CN1204267A - Intravenous catheter with flexible extender and protector against needle tip - Google Patents

Abstract

An intravenous catheter assembly with flexible extender and protector against needle tip comprising an intravenous catheter (2) together with a flexible extender (7) for infusions, passing over an introducing needle (1), which extender (7) may prevent the undesirable escape of blood or other infusions with a simple strangulation. It is essentially composed of a rigid or semi-flexible concave handle (16) which shelters the needle (1) and the other components, including the flexible extender (7); by using the handle-casing, the catheter packaging is discarded, requiring only a lid (17) which combined with the handle (16), hermetically closes the catheter (2). A protector for the needle tip is also provided for effecting greater safety and hygiene.

Description

IV Tubing with Flexible Extension and Needle Tip Protector

The article entitled "IV Tubing with Flexible Extension and Needle Tip Protector" is characterized in that it has a small flexible tube for infusion, which prevents blood flow from simple choking, which is the case It can be caused by using only one hand until the tubing or its cap is attached. Therefore, its process of attaching to the patient's body becomes easy without worrying about blood flowing out, which is superior to the utility model "single outlet vascular device" which causes bleeding due to the hole in the latex body (flexible glove curve) , which is just as the traditional infusion tube caused by various reasons. In addition, there is a protector for protecting the needle point on it, which is located at the needle end, and is used to separate it from the needle point after the infusion tube is connected.

The following is a description of the drawings and a description of each component:

Figure 1 shows the use position of "intravenous infusion tube with flexible extension piece and needle tip protector";

Figure 2 shows the moment after the infusion tube is inserted into the vein, wherein it shows the flexible extension piece being squeezed by hand, and also shows the action of the protector protecting the needle tip.

Figure 3 shows the separation of the infusion tube from the opening: the protector is attached to the infusion tube until the safety wire is fully extended, preventing the protector from being separated from the rest of the device, and placing it in the operating position;

Figure 4 shows the semi-flexible handle in use;

Figure 5 shows the device in a cylindrical, small, sealed housing that protects the needle tip, infusion tubing and flexible extension. Finally, the support frame is occupied by each component, and the arrangement of each component is completed;

Figure 6 shows the position of use of the device;

Figure 7 shows isolated parts of the present invention;

Figure 8 illustrates the operation of the device, showing the support frame with the needle after the infusion tube is secured.

The components in the figure:

1 - An introducer needle, the length of which can pass through the entire length of the flexible extension to reach the other end, the tip of the infusion tube. The thinner needles can be separated to form slits to facilitate observation of blood flow.

2- IV tubing set.

3- Vessels.

4 - Rigid (or flexible) infusion tube set base, which is connected to the flexible tube 7 for infusion, which has an inner cone and an outer cover around it.

5-Protrusion in the concave handle of the instrument, used for the opening 4 of the infusion tube sleeve.

6-cooperating part, it must be connected with instrument body protrusion 5, guarantees stability when piercing.

7-transfusion flexible tube, connected to the base part 4 of the transfusion tube cover.

8 - The opening of the infusion flexible tube, through which the guide needle passes, which cooperates with the protective claw.

9-needle protection claws, including: two bent pressure sheets, facing the needle so as to isolate its tip; and two bent flanges, facing the wall of the opening 8 of the infusion extension piece. When the stop cable 13 is extended, the protector separates from the opening of the infusion extension, and it is automatically in the position on the needle point, which is not connected with the infusion tube at this moment.

10 - Rigid contact area 11 or flexible contact area 14 .

11 - Infusion tube holder, which is a female handle, which protects the needle by surrounding it, the extension piece and the needle tip protector, all these pieces are connected by its inner part.

12 - The needle base located inside the infusion tube holder 11 with a filter at its bottom.

13-stop wire, which is a thin wire with certain strength and length, so as to prevent the protector 9 from breaking away.

14 - Semi-flexible concave handle, which presses against the flexible connector 4, providing greater sensitivity and stability when piercing blood vessels with thin needles.

15 - slit in needle to confirm blood flow.

16 - Cylindrical handle, which protects the rest of its interior.

17-Sealing the cover of the device.

18—infusion tube guide needle base part, fixed on the bottom.

19 - Bracket with semi-flexible sides with holes 20 and cavities 22 that limit the movement of the bracket.

20—The hole is matched with the housing protrusion 21 .

21 - the inner protrusion of the handle (housing) 16.

22 - Bracket cavity intended to cooperate with said protrusion 21 and limit its movement inside the handle-housing.

Claims (4)

1. venous transfusion pipe that has flexible and extendable and needle tip protector; it is characterized in that it has a transfusion flexible and extendable (7) and transfusion pipe box substrate (4), three kinds of dissimilar handles (11; 14 and 16), and the columnar stays frame (19) of puncture back protection needle point.

2. the venous transfusion pipe that has flexible and extendable and needle tip protector as claimed in claim 1 is characterized in that it has an indent handle (11), and it is around flexible and extendable (7); And a fixed lobe (5), the indenture in transfusion pipe box substrate (4) cooperates, as Fig. 1, shown in 2 and 3.

3. the venous transfusion pipe that has flexible and extendable and needle tip protector as claimed in claim 1 or 2; it is characterized in that; it has half flexible grip (14) of an indent; the pin that its protection one is thin; this pin has a hole in the middle; so that when arriving blood vessel, indicate, when being installed, tube for transfusion provides susceptiveness (Fig. 4) preferably.

4. as the described venous transfusion pipe that has flexible and extendable and needle tip protector of claim 1,2 or 3, it is characterized in that it has a column handle (16), this handle is protected within it portion (18) (pin depart from be shown in Fig. 5,6,7 and 8) with guid needle (2); And having bracing frame (19), it departs from the protection needle point.
