Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a syringe, and more particularly, to a syringe which does not require calculation of a drug dose at the time of use.

[0002]

2. Description of the Related Art Drugs are often based on the weight of the patient when setting the dose. In addition, the use of some drugs is 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 an injection syringe to administer the drug.

A concrete example is as follows. The drug to be administered is, for example, drug A, and 1 g of drug A is used.
Is dissolved in 20 ml of physiological saline and diluted to 5 m per kg of body weight
g administration. For example, if the weight of a patient is 60 kg, the amount of drug to be administered to this patient is 60 kg × 5 mg = 300 mg. 20 ml dissolved in physiological saline is 100 drug A
20ml (300/1000) from 0mg
That is, 6 ml will be administered.

[0004]

Conventionally, in administering a drug to an injecter such as a patient, as described above, the total dose is calculated in advance in a clinical setting, and then the syringe for injection is dissolved in physiological saline. 6 ml out of 20 ml was administered. Thus, in the past, medical care and nursing staff in the clinical setting used to calculate drug doses each time, which made the medical work complicated and time-consuming, and there was an opportunity to make medical mistakes due to incorrect calculations. There were many. Therefore, the present invention is intended to improve such conventional drawbacks, and an object thereof is to provide a syringe and a syringe which can immediately determine a dosage and administer the dosage if the weight of an injecter such as a patient can be confirmed. It is intended to provide a printer for a label to be attached.

[0005]

[Means for Solving the Problems] All of the syringes currently used in clinical practice are displayed in ml (milliliter) indicating a dose. As described above, in actual use, many drugs are indicated to use a drug amount of mg (milligram) or ml per body weight of the injector such as a patient. Therefore, taking the above A drug as an example,
If the standard of the medicine is 1g and it is sure to dissolve in 20ml physiological saline, the weight of 10k per 1ml of syringe
Attach the label prepared in the ratio of g to the syringe and weigh 60
When the drug A is administered to an injector such as a patient of kg, the drug is inhaled up to a position of 60 kg with a syringe scale and is administered to the injector such as a patient. As can be seen from the above, the syringe of the present invention is provided with a weight scale in place of the dose scale so that the dose is shown according to the weight of the patient or the like. Therefore, it is necessary to design the drug so that it has a constant concentration and to match it with the syringe scale, or to set a dedicated syringe for a specific drug. The sticking of the label on the syringe is a simple method, but when a syringe is manufactured by a pharmaceutical company, it is preferable to combine it with the drug to be used and engrave a label specific to the drug on the surface of the syringe.

In FIG. 1, reference numeral 1 is a syringe having a syringe 2. The syringe 1 is made of transparent or translucent glass or synthetic resin, has a cylindrical liquid reservoir 3 having the same cross-section, and is continuously formed in the longitudinal direction. The liquid reservoir 3 can be observed from the outer surface. A liquid inlet / outlet port 4 that allows an injection needle to be attached to one opening end of the syringe 1 to allow the liquid to enter and leave the liquid reservoir 3.
Are formed. A plunger 5 that is inserted into the liquid reservoir 3 from the other end of the syringe 1 and is slidable on the inner surface of the liquid reservoir 3 is inserted in the liquid reservoir 3. On the surface of the syringe 1,
Display unit 8 displaying the corresponding drug name 6 and weight scale 7
Is provided. Each position on the weight scale 7 is a mark that is a position for displaying the dose of the liquid medicine unique to the patient who receives the medication.

Next, the display method of the display section will be described with reference to a specific example shown in the above paragraph 0003. It is assumed that 1 g of the 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 weighs 60
If the dose is kg, the dose of drug required for this patient is 60 kg × 5 mg = 300 mg. 20 ml dissolved in physiological saline is 100 drug A
20ml (300/1000) from 0mg
That is, 6 ml will be administered. Therefore, the weight scale 7 of the display unit 8 may be a scale of 10 kg of body weight for each 1 ml dose of the liquid reservoir 3. The calculated drug solution for administration does not include the age of the patient. If necessary, a correction value according to age, for example, 0.5 for children,
A dosage value may be determined by using a count value such as 1.0 for an adult and 0.7 for an old person and multiplying the calculated value by the calculated amount of the solution of the administered drug. INDUSTRIAL APPLICABILITY The present invention is advantageous in that it is simple and that an appropriate dosage can be reliably administered. For highly urgent drugs and drugs for which the dose calculation is complicated, if the dose for the body weight is calculated in advance and the label of the syringe is designed, even if the dose is difficult to measure, Appropriate administration becomes possible by referring to the scale.
In addition, if the attached solution that complies with the internal volume standard is attached to a syringe in which the dose per body weight is entered at the time of drug production and is sold as a kit, the scale per body weight can be calculated even if the dose is difficult to measure. The appropriate administration becomes possible by referring to.

Next, an explanation will be given of emergency measures in the case where a drug must be urgently administered to a patient due to the occurrence of a sudden accident or the like, and the above-mentioned syringe according to the present invention is not prepared. . First, prepare a printer with the following label. That is, as shown in FIG. 2, the printer 10 has a central processing unit 11 as the center, an input device 12 having keys for entering drug names, and corresponding to each drug name, per 1 kg of body weight of an injecter such as a patient.

As shown in FIG. 3, the input device 12 has a plurality of keys 16 on which drug names are entered. Regarding the arrangement of the drug names displayed on these keys 16, care must be taken not to place confusing drug names or drug names with different actions in close proximity in order to avoid medical mistakes. As described above, the memory 13 is in the state as shown in FIG. 4 (1) and corresponds to the plurality of drug names displayed on the input device 12, the drug solution dilution amount, and the drug administered per kg body weight of the injecter such as the patient. Data indicating the amount is stored.

The data read from the memory 13 is sent to the central processing unit 11. Here, for example, a syringe 1 m of the syringe used from the data shown in FIG.
The structural data such as 0.1 ml per m has been read out, and the body weight of the injecter of the drug, etc. sent from the drug is 1 kg.
Print data indicating the weight of the injecter of a patient or the like corresponding to the amount of the dissolved drug solution inhaled in the syringe is created based on the data of the amount of the dissolved drug solution per hit, 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.

[0012] The printed label is taken out by a medical staff, and is accurately adhered to the surface of the syringe by a predetermined method, and then the administered drug solution is inhaled up to the weight position of the injecter such as the patient displayed on the label. And administered to the injector such as the patient. Accurately attaching the printed label to the surface of the syringe requires considerable skill. Therefore, if the syringe is accurately positioned and set in the printer and the label is printed on the syringe, the syringe can be rotated, for example, so that the label is attached automatically and accurately. Can be attached to.

A patient's body weight and age are recorded in the medical record in which the progress of medical treatment and the illness are described for the patients who are going to the hospital or in the hospital.
Using the personal information recorded in this chart, prepare a syringe with a label attached in advance before regular medical treatment, inhale the drug solution into the syringe at the time of examination, and administer it to the patient. It will be 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 name and weight of the patient can be input from the input device 12. Based on these input data, the data indicating the amount of administered drug solution per 1 kg of patient weight read from the memory 13 to the central processing unit 11 is multiplied by the patient's weight, and the required amount of dissolved drug inhaled into the syringe. The print data indicating the position of is generated, 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 or the name of the administered drug may be printed on the label. Of course, this device is not limited to handling a single drug, and it is also possible to store a plurality of types of drug data in the memory 13 as described above and create a label corresponding to a plurality of types of drugs.

Although the present invention has been described with reference to the above-described embodiments, the present invention can be applied not only to administration of drugs to patients but also to administration of nutritional supplements and blood transfusion as in the above-described embodiments. You can Further, for example, instead of the method of printing a label and adhering it to a syringe as in the above-described embodiment, a label is directly engraved on the surface of a syringe when a syringe is manufactured by a pharmaceutical company. For example, various modifications and applications are possible within the scope of the present invention, and these modifications and applications are not excluded from the scope of the present invention.
