Description

  The present invention relates to a structure of a syringe, and more particularly to a syringe that does not require calculation of a dose of a drug at the time of use.

  Drugs are often based on the patient's weight in setting their dose. In addition, some drugs have their usage limited by age and weight. Therefore, in clinical practice, when the drug is used as an injection, the total dose is calculated in advance, and the required amount is measured with a syringe for injection, and medication is performed.

  The following are specific examples. The drug to be administered is, for example, drug A, and 1 g of drug A is dissolved and diluted in 20 ml of physiological saline and administered at 5 mg per kg body weight. For example, if the patient's weight is 60 kg, the amount of drug required for this patient is 60 kg × 5 mg = 300 mg. Since 20 ml dissolved in physiological saline becomes 1000 mg of drug A, 20 ml (300/1000), that is, 6 ml is administered.

  Conventionally, when administering a drug to an infusion subject such as a patient, as described above, the total dose is calculated in advance in the clinical field, and then 6 ml of the 20 ml syringe for injection dissolved in physiological saline is administered. It was. Thus, in the past, medical nurses in clinical settings had to calculate troublesome drug dosages, which complicated the medical work and required a long time. There were many. Therefore, the present invention aims to remedy such conventional drawbacks, and an object of the present invention is to provide a syringe that can determine and administer the dosage as soon as the body weight of the person to be injected such as a patient can be confirmed, and the syringe. It is intended to provide a printer with a label to be attached to the printer.

  All syringes currently used in the clinical setting are in ml (milliliter) indicating the dose. As described above, in the actual use situation, there are many drugs that indicate how many mg (milligram) or how many ml of drug per body weight of an injection subject such as a patient is used. Therefore, taking the example of the above drug A, if the standard of drug A is 1 g and it is certain that it will dissolve in 20 ml of physiological saline, a label made at a ratio of 10 kg body weight per ml of syringe is affixed to the syringe. When the drug A is administered to an infusion subject such as a patient weighing 60 kg, the drug is inhaled to the position of 60 kg with a syringe scale and administered to the infusion subject such as a patient. As can be seen from the above, the syringe of the present invention is provided with a body weight scale instead of the dose scale so as to show the dose corresponding to the body weight of the patient or the like. Therefore, it is necessary to design the drug at a constant concentration and match the syringe scale, or a specific syringe setting for a specific drug. Affixing the label to the syringe is a simple method, but when a syringe is manufactured by a pharmaceutical company, it may be combined with a drug used and a label peculiar to the drug may be engraved on the syringe surface.

  Next, an embodiment of the present invention will be described in detail with reference to the drawings. This will be described in detail with reference to FIG. FIG. 1 is a front view of a syringe according to the present invention. In FIG. 1, reference numeral 1 denotes a syringe having a syringe 2. The syringe 1 is made of transparent or translucent glass or synthetic resin, and has a liquid reservoir 3 continuously formed in the longitudinal direction with a cylindrical shape having the same cross-sectional shape, and the liquid reservoir 3 can be observed from the outer surface. A liquid inlet / outlet 4 is formed at one opening end of the syringe 1 so that an injection needle can be attached and liquid can enter and exit the liquid reservoir 3. A plunger 5 inserted into the liquid reservoir 3 from the other end of the syringe 1 and slidable with the inner surface of the liquid reservoir 3 is inserted into the liquid reservoir 3. On the surface of the syringe 1, a display unit 8 on which a corresponding medicine name 6 and a weight scale 7 are displayed is provided. Each position of the weight scale 7 is a mark that is a position for displaying a liquid dose unique to a patient who receives medication.

  Next, the display method of the display unit will be described using a specific example shown in paragraph 0003 above. It is assumed that 1 g of drug A to be administered is dissolved and diluted in 20 ml of physiological saline and administered at 5 mg per kg body weight. For example, if the patient's weight is 60 kg, the amount of drug required for this patient is 60 kg × 5 mg = 300 mg. Since 20 ml dissolved in physiological saline becomes 1000 mg of drug A, 20 ml (300/1000), that is, 6 ml is administered. Therefore, the weight scale 7 of the display unit 8 may be a scale of 10 kg for each 1 ml dose of the liquid reservoir 3. The patient's age is not taken into account in the above-calculated administered drug solution. If necessary, a correction value based on age, for example, a count value such as 0.5 for children, 1.0 for adults, 0.7 for elderly people, etc. is used. You may decide. The present invention is advantageous in that it can be administered with ease and with an appropriate dosage reliably. For highly urgent drugs and drugs with complex dose calculations, calculate the dose for the above body weight in advance, and further design the syringe label, so even if the dose is difficult to measure, Appropriate administration becomes possible with reference to the scale. In addition, if you make a kit with a syringe containing the dose per body weight up to the attached dissolution solution that conforms to the internal volume specification at the time of drug production, even if the dosage is difficult to measure, the scale per body weight Appropriate administration becomes possible with reference to FIG.

  Next, an emergency measure in the case where a drug has to be urgently administered to a patient due to the occurrence of a sudden accident or the like, and the syringe according to the present invention as described above is not prepared will be described. First, a printer with the following label is prepared. That is, as shown in FIG. 2, the printer 10 has an input device 12 having a key on which a medicine name is entered centered on a central processing unit 11, and corresponds to each medicine name per 1 kg body weight of an injection target person such as a patient. In addition to storing map data in which data indicating the amount of the administered drug solution is stored, the memory 13 storing the structure data of the syringe used, the progress of the processing of the central processing unit 11 and the calculation results, etc. Are temporarily stored, and a printing unit 15 for printing a label is included.

  As shown in FIG. 3, the input device 12 has a plurality of keys 16 in which drug names are entered. With regard to the arrangement of the drug names displayed on these keys 16, care must be taken such as avoiding misplaced drug names or drug names having different actions from being placed close to each other in order to avoid medical errors. As described above, the memory 13 is in the state shown in FIG. 4 (1), corresponding to a plurality of drug names displayed on the input device 12, and the dose per 1 kg body weight of the infusion subject such as a patient. Data indicating the amount of medicine is stored.

  Data read from the memory 13 is sent to the central processing unit 11. Here, structural data such as 0.1 ml per 1 mm syringe of the syringe used is read from the data shown in FIG. 4 (2), and the patient to be injected, such as a patient of the drug that has been sent. Print data indicating the weight of the person to be injected, such as a patient, corresponding to the amount of solution medicine to be inhaled into the syringe is created based on the amount of medicine solution amount data per kg of body weight, and this data is sent to the printing unit 15. . The printing unit 15 prints a label using the print data sent from the central processing unit 11.

  The printed label is taken out by a medical staff, and is adhered to the surface of the syringe accurately by a predetermined method, and then the administered drug solution is inhaled to the weight position of the injecting subject such as a patient displayed on the label, It is administered to infusion subjects such as patients. In addition, attaching a printed label correctly to the syringe surface requires considerable skill. Therefore, if the syringe is accurately positioned and set on the printer, and the label is printed on the label, for example, the syringe is rotated and automatically attached to the label. Can be attached.

  A medical record describing the progress of treatment and disease is issued to patients who are out of hospital or hospitalized, and the patient's own weight and age are recorded in this medical record. Using the personal information recorded in this medical chart, prepare a syringe with a label attached in advance before regular medical examinations, inhale the drug solution into the syringe at the time of examination, and administer to the patient This is convenient. In such a case, a personal computer keyboard is connected to the input device 12 of the printer 10 so that character data can be input, and the patient's name and weight can be input from the input device 12. Based on these input data, the data indicating the amount of the administered drug solution per kg of the patient's body weight read from the memory 13 to the central processing unit 11 is multiplied by the patient's weight, and the required amount of the dissolved drug to be inhaled into the syringe Print data indicating the position of the image is created, and this data is sent to the printing unit 15. The printing unit 15 prints a label for a specific patient using the print data sent from the central processing unit 11. If necessary, the name of the specific patient and the name of the administered drug may be printed on the label. Of course, this apparatus does not limit the chemicals to be handled to a single item. As described above, a plurality of types of chemical data can be stored in the memory 13 to create labels corresponding to a plurality of types of chemicals.

  Although the present invention has been described by the above embodiment, the present invention can be applied not only to the administration of a drug to a patient but also to the administration of a nutrient or blood transfusion as in the above embodiment. Further, for example, instead of a method of printing a label and sticking this to a syringe as in the above-described embodiment, a label is directly engraved on the surface of the syringe when the syringe is manufactured by a pharmaceutical company. Various modifications and applications are possible within the scope of the gist of the present invention, and these modifications and applications are not excluded from the scope of the present invention.
