Description

 Specification

 Injection needle safety equipment

 Technical field

 The present invention relates to a safety device for an injection needle that can prevent a needle injection accident in which a used injection needle accidentally stabs a finger or the like beforehand.

 Background art

 [0002] In recent years, a so-called "needle stick accident" in which doctors, nurses, hospital cleaners, and the like accidentally stab an injection needle used for a patient with a finger or the like has become a problem. As a result of this needlestick accident, healthcare workers and medical waste processors are infected with HIV (Human Immunodeficiency Virus, so-called AIDS Winores), HCV (Hepatitis C virus), HBV (Hepatitis B virus), etc. from the patient's blood. He has been forced to live for a long time and has died.

 [0003] A needle puncture accident occurs most often when a doctor or the like injects a syringe and then recaps the syringe needle (put it in a protective cap). Then, the staff forgets to put the needle on the bed sheet of the meal tray and the staff cleans it up. It has been reported that this may occur at the time of disposal or when it is disposed of in a plastic bag other than the specified waste container.

 [0004] As a preventive measure against needle sticks, after the injection, the injection needle is pulled out of the affected area, then the injection needle is not recapped and discarded in a waste container as it is. Disposal is recommended from all directions!

 [0005] However, without recapping, it is more likely that the doctor or nurse who injected the needle will prevent needle sticks, but if subsequent measures are not taken properly, measures other than the person who injected the injection will be taken. The risk of needle sticks for personnel and waste handlers is much higher than when recapped.

 [0006] Therefore, returning to the basics, it is most desirable to be able to reliably recap by an operation method without causing needle sticks.

[0007] As described above, the recapping is to cover the injection needle attached to the syringe with a protective cap again after the injection.

[0008] Although this protective cap varies depending on the injection needle used, it has a large force of several mm in diameter. It is only about 10 mm in diameter, and when inserting the needle tip through the opening formed at one end and putting it over the injection needle, the needle tip is not inserted well into the small opening and the protective cap is held. Often stabbed fingers.

[0009] In order to solve such a problem, Patent Documents 115 and the like propose injection needle protection caps having various structures.

[0010] Patent Document 1 discloses a needle tip protection cap in which a brim is attached to an end. As a result, even if the position of the injection needle is mistakenly shifted when inserting the injection needle into the protective cap, the finger with the protective cap will not be stabbed by the collar because it will be blocked by the collar. ing.

 [0011] In the device disclosed in Patent Document 2, a lever that acts as a lever or a wedge is attached to a protective cap. When the syringe needle is inserted with the lever during use, the distance between the syringe needle and the fingertip is increased. It is said that it is possible to prevent the finger from hitting the tip of the injection needle or accidentally injuring the fingertip.

 [0012] Patent Document 3 discloses a large opening area in which an extended portion is provided in one half of an insertion port portion of an injection needle cap and a shortened portion is provided in an opposite half portion. The center of gravity of the needle is shifted to prevent rolling down when the needle cap is temporarily placed on a desk when not in use.

 [0013] The one disclosed in Patent Document 4 is one in which a vertically split groove having a width that allows insertion of a needle tip is formed in a part of the body of the protective cap. During use, the needle is inserted into the protective cap along the vertical groove so that the entire needle is dropped, preventing the needle from moving in the direction of piercing the finger and preventing accidental needle sticks. It is possible.

 [0014] The one disclosed in Patent Document 5 has a guide groove formed on the side surface of the opening of the injection needle. The side surface of the injection needle is applied to the guide groove and pulled in the direction opposite to the needle tip. By dropping the tip into the insertion slot and then inserting the needle tip into the main body, it is possible to prevent the needle tip from coming out of the insertion slot at the time of mounting, which allows the needle tip to be moved by hand or finger. It is said that puncture accidents can be prevented beforehand.

[0015] However, all of these protective caps require an operation in which a doctor or the like holds the protective cap with the hand opposite to the hand holding the syringe after injection and covers the injection needle. That is, note Since the hand with the protective cap comes over the extension of the shooting needle, there is a risk that the needle will be stuck in that hand, even if careful.

 [0016] On the other hand, Patent Documents 6 to 8 propose a jig for holding a protective cap.

[0017] Patent Document 6 discloses a cap in which a cap table and a needle guide are integrated or paired, a bend is provided in the cap table and the injection needle guide, and a step is provided at a boundary between the cap table and the injection needle guide. It is an attaching machine. When using, set the protective cap on the cap base and move the injection needle with the guide needle bend as a guide.Since the protective cap opening is on the extension of the bend, insert the needle smoothly into the protective cap. it can. Since the cap stand is used by setting it on a stand that can be held by hand, there is no hand holding the syringe on the extension of the injection needle.

 [0018] In the structure disclosed in Patent Document 7, the peripheral wall including the insertion port is cut out in a vertically elongated shape toward the distal end from the insertion port side cap, and is directed toward the insertion port toward the distal end of the notch. It has a case body that can store a plurality of injection needle protection caps with locking pieces for locking winged needles, and this case body exposes the notch of the stored protection cap to allow used injection needles. An injection needle processing tool that has a take-out port that keeps it attachable and that can take out the protective cap one by one, a panel that urges the stored protective cap toward the take-out port, and a handle on the case body. .

 [0019] Patent Document 8 discloses a case body that stores a plurality of protective caps, holds the protective caps in a position where a used injection needle can be inserted from an insertion port, and attaches the case to the case body. And an opening / closing lid for preventing the injection needle protection cap from coming off.

 Disclosure of the invention

 Problems to be solved by the invention

 [0021] The device disclosed in Patent Documents 6 to 8 solves the problem of the protective cap disclosed in Patent Documents 15 to 15. However, the capping machine disclosed in Patent Document 6 discloses an injection device. Since the needle comes into contact with the bent part, blood adhering to the tip of the injection needle is more likely to adhere to the needle guide, and there is a risk of infection by skin contact with the blood.

 [0022] The injection needle processing tool disclosed in Patent Document 7 inserts the injection needle into the protective cap by holding the handle provided on the case main body with the vacant hand, and thus there is no danger of needle stick. You need to use

 [0023] The injection needle treatment tool disclosed in Patent Document 8 also basically needs to use both hands because it holds the case body with another hand different from the hand holding the syringe.

 [0024] After a doctor or the like makes an injection, the needle of the syringe is removed from the patient's body, and when the needle is pierced, the puncture of the skin causes blood to come out. You need to wait for the blood to clot and stop. Normally, the patient is instructed to hold it by himself, but if the patient is weak or unconscious, the doctor who injected the medicine will use the hand opposite to the hand holding the syringe that was removed. It is necessary to hold down. Then, the device of Patent Documents 6 to 8 using both hands to insert the protective cap cannot be used. If you ask your attendant or nurse to hold the cotton wool, you will still be exposed, and people will move near the needle, increasing the risk of needle stick.

 [0025] In the device of Patent Documents 6-8, another stand is provided on a table or the like so that the injection needle can be inserted into the protective cap with only one hand (the hand holding the syringe). Although devised, the injection site does not always have a place to put a stand nearby. On bed sheets, the stands are not stable and fall off the sheets. When picking up a fallen stand, the injection needle may pierce a doctor or other people.

[0026] Therefore, an object of the present invention is to provide a safety device for an injection needle that allows the injection needle to be reliably inserted into the protective cap with only the hand holding the injection device. Means for solving the problem

 [0027] In order to solve the above problem, a safety device for an injection needle according to the first configuration of the present invention includes a protective cap having a claw portion that engages with a flange portion or a proximal end portion of the injection needle near an opening. And a case body for storing and holding at least one of the protective caps, and a case holding means for stably holding the case body on a support is provided.

 [0028] In the first configuration, the case main body is used by holding the case main body at an arbitrary place such as a desk in an examination room, a bedside of a patient, or on a sheet of a patient by a case holding means. The doctor or nurse installs the safety device of the present invention containing the protective cap at an arbitrary place before the injection. Next, after injecting the syringe with the dominant hand, for example, the right hand, hold the syringe and inject the needle with the left hand while holding down the part where the needle of the syringe is stabbed with absorbent cotton, etc., and then withdraw the injection needle. When the syringe is inserted through the opening of the protective cap, the collar formed at the base end of the injection needle engages with the claw provided near the opening of the protective cap. Since the cap is detached from the case body, the state of the injection needle covered with the protective cap is obtained. During this time, the case body is held in place by the case holding means, so when inserting the injection needle into the protective cap or removing the protective cap, the case body is Does not move with the syringe, and the protective cap can be securely attached. The syringe needle is then withdrawn from the tip of the syringe cylinder with a protective cap and discarded in a designated safety container. The case body may be configured to store and hold one protective cap. This is convenient for disposing each time when it is used only once, such as when injecting into a hospital bed or at a house call. A configuration in which a plurality of protective caps are housed and held in the case body may be employed. This is convenient for processing multiple protective caps at once when multiple patients are injected continuously, such as vaccination injections, or when several types of injections are given to a single patient during surgery. Yes, and economical. In addition, the injection needle is usually provided with a flange at the base end, but there is a case where there is no flange like an indwelling needle. In this case, a claw provided near the opening of the protective cap is used. The base end of the indwelling needle is hooked on the part, so that it functions as a stopper.

[0029] In a second configuration of the present invention, the case holding means is provided on a back surface of a case body, It is a non-slip layer that increases friction with the surface of the support.

 [0030] In the second configuration, since the anti-slip layer is provided on the bottom surface of the case body, the case body can be placed at an arbitrary location such as a desk in an examination room, a bedside of a patient, or on a sheet of a patient. When placed, it can be installed in a state where it does not easily move in the horizontal direction. When the protective cap is put on the injection needle after injection, the case body is held in place by the non-slip layer, so when inserting the needle into the protective cap or removing the protective cap, the case body Even if the force in the direction is strong, the protective cap can be securely attached so that the case body does not move with the syringe.

[0031] A third configuration of the present invention is characterized in that the anti-slip layer is a silicone rubber layer.

[0032] According to the third configuration, the frictional resistance between the case main body and the installation surface is increased, so that when the injection needle is inserted into the protective cap, even if a force in the front-rear and left-right directions is applied to the case main body, The moving body can be prevented from moving.

 [0033] A fourth configuration of the present invention is characterized in that the anti-slip layer is an adhesive layer.

[0034] In the fourth configuration, a doctor or a nurse can attach a case body having an adhesive layer formed on a bottom portion to an arbitrary place before injection. Since the adhesive layer effectively adheres to the surface of the fiber, it is perfectly fixed even when the fixing partner is a cloth such as a sheet. When multiple protective caps are stored and held in the case body, the adhesive strength of the adhesive layer weakens as it is pasted and peeled in place, but this case body uses a protective cap. Since it is discarded in the finished state, it is sufficient if it can be adhered as many times as the number of protective caps.

 [0035] A fifth configuration of the present invention is characterized in that a release paper is attached to the surface of the adhesive layer. Thereby, the surface of the adhesive layer can be protected, and the release paper can be peeled off and attached at the time of use.

 [0036] A sixth configuration of the present invention is characterized in that the adhesive layer is a double-sided tape. Thereby, the adhesive layer can be easily formed.

[0037] In a seventh configuration of the present invention, the bottom surface of the case main body provided with the anti-slip layer and the center axis of the protective cap held by the case main body are inclined such that the opening side of the protective cap is higher. The feature is that. [0038] According to the seventh configuration, when the syringe is inserted into the protective cap after the case main body is adhered to a predetermined place, the injection needle is not inserted along the adhered surface. Since the injection needle can be inserted at a certain inclination angle, it can be easily aimed at the opening of the protective cap and can be easily mounted.

 [0039] In an eighth configuration of the present invention, the case holding means is mounted on the support, has at least one edge, and has a protrusion or groove formed substantially parallel to the edge surface. And a resilient leg formed at the lower front part of the case main body. The rear of the case main body is brought into contact with the edge of the substrate, and the front leg of the case main body is projected or grooved on the substrate. , Whereby the case body is held on the substrate.

 [0040] In the eighth configuration, a case in which legs are provided at the lower front portion of the case body is used, and an edge and a projection or a groove are provided on a substrate that can be placed on a tabletop or a bedside, and the edge and the projection are provided. Alternatively, if the case main body is mounted in such a manner that the front leg is engaged with the protrusion or the groove so that the rear portion contacts the edge between the grooves, the case main body can be held on the substrate. As the substrate, a substrate having heat resistance and chemical resistance such as stainless steel is preferable so that it can be washed many times after use, sterilized by high-temperature sterilization or sterilized with a chemical solution. The substrate may be in the form of a tray with an edge, which is usually used in hospitals, but may be a substrate having an edge at one location.

 The invention's effect

 According to the present invention, there is provided a protective cap having a claw engaging with a flange of an injection needle near an opening, and a case main body for storing and holding at least one protective cap, With a configuration that provides a case holding means that stably holds the main body to the support, the needle can be securely inserted into the protective cap with only the hand holding the syringe, and the needle is inserted into the other hand. In addition, no bleeding occurs, and the patient can perform treatment such as hemostasis with the free hand.

 BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.

 [Embodiment 1]

FIGS. 1 and 2 show a configuration of a case main body in a safety device for an injection needle according to Embodiment 1 of the present invention, wherein FIG. 1 ( _a ) is a plan view, (b) is a side view, (C) is a sectional view taken along line A-A in (a), (d) is a front view, (e) is a sectional view taken along line B-B in (a) and (c), and FIG. 2 is a bottom view. It is. FIGS. 3A and 3B show the configuration of the protective cap in the safety device according to the first embodiment, where FIG. 3A is a cross-sectional view, FIG. 3B is a plan view, FIG. 3C is a right side view, and FIG. (B) is a CC sectional view.

 In these figures, the case main body 10 includes a top plate 11, a bottom plate 12, a side plate 13, a partition wall 14, and a protective cap end receiver 15. A leg 16 curved downward is formed at the front bottom of the case main body 10, so that the case main body 10 is inclined and placed on the installation surface. The bottom plate 12 comes into close contact with the installation surface with the case body 10 inclined. The partition wall 14 and the protective cap end receiving portion 15 form a protective cap mounting space in which a protective cap 20 (described later) is mounted. The bottom plate 12 is provided with an adhesive layer 17 formed by attaching a double-sided tape or the like, and a release paper is usually attached when not in use.

 In front of the top plate 11, a tongue piece 11a extends so as to be located at the center of each protective cap mounting space, and a projection 1 lb is formed at the lower center of the tongue piece 1 la. You.

 As shown in FIG. 3, the protective cap 20 is engaged with the cap body 21, the concave portion 22 with which the projection l ib of the case body 10 is engaged, and the proximal end flange of the injection needle (described later). A claw portion 23 is formed to prevent falling off. In order to form the claw portion 23 with a resin injection molding die, a ridge 24 is formed inside the cap body 21 and an opening 25 for receiving a slide core is provided. Although FIG. 3 shows one claw portion 23 provided at the upper portion inside the front opening of the protective cap 20, a plurality of claw portions 23 may be provided on the circumference inside the front opening.

FIG. 4 is a perspective view showing a use state of the first embodiment, and FIG. 5 is a cross-sectional view showing a state where an injection needle is attached to a protective cap. The case body 10 according to the first embodiment has a state in which six protective caps 20 are set in this example such that the concave portions 22 are fitted into the projections lib below the tongue pieces 11a. The release paper of the adhesive layer 17 attached below is peeled off, and attached on, for example, a patient sheet. Next, after the doctor or nurse performs the injection, the tip of the injection needle 31 is inserted into the protective cap 20 while holding the syringe 30. Then, the collar 32 at the proximal end of the injection needle 31 pushes up the claw 23 and passes through the claw 23. When the syringe 30 is pulled out in this state, the claw 23 is hooked on the flange 32. The engagement between the projection l ib under the tongue piece 11a of the case body 10 and the recess 22 of the protective cap 20 is weak. Since the case body 10 is fixed to sheets or the like, when the syringe 30 is pulled out, the protective cap 20 is pulled out from the case body 10 with the protective cap 20 attached to the injection needle 31.

 [0050] In this way, a doctor or the like can cover the injection needle with the protective cap after performing the injection with the syringe 30 without changing the posture of the hand holding the syringe. Since this operation can be performed with one hand holding the syringe 30, it is possible to perform a procedure such as pressing a bandage for hemostasis with the other hand, and it is necessary to turn the other hand around the tip of the injection needle. Therefore, safety can be maintained.

 [0051] Further, as shown in Fig. 1 (b), the case main body 10 is provided to be inclined with respect to the bottom plate 12, so that the injection needle is attached to the protective cap 20 attached to the case main body 10. Insertion and pull-out operation force Since it can be performed diagonally from above, it can be performed naturally without any difficulty in the posture of the wrist.

 [0052] After the injection, the case body 10 is also peeled off from the place where it was affixed, is attached with release paper, and is reused by the number of protective caps. In this example, since six protective caps 20 are attached to the case body 10, the case body 10 is discarded after being used six times. The injection needle covered with the protective cap 20 is also disposed of according to a predetermined standard.

 In the first embodiment, since a plurality of protective caps 20 are housed and held in the case main body 10, a case where a plurality of patients are continuously injected, such as a preventive injection, or a surgical operation is performed. It is convenient and economical to process a plurality of protective caps 20 together when several injections are given to one patient.
