Description

[Detailed description of the invention] (Medical application field) This invention relates to improving medical care.

Hygiene is paramount in medical care, and for this reason, syringes and the like are currently sterilized and used only once and then thrown away.

Even if the syringe is sterilized, when you put the drug into the syringe, there are tons of dirty dust in the outside air! It is unsanitary because it gets in together with 41α.

If that is the case, it would be very convenient to use the new syringe if it was filled with medicine from the beginning, but there would be problems in preserving the medicine inside, and this method is less hygienic than the conventional method. There's a problem. For this reason, this invention relates to a medicine container containing an injection solution and a syringe for injecting it into a patient or living body, which is an invented method for handling the injection solution hygienically and labor-savingly (prior art).When using an injection solution It was used for treatment, diagnosis, prevention, etc., and the amount used varied widely, and the shape and material of the medicinal container differed depending on the amount of medicinal solution.

The material was made of synthetic resin Yagarasu. For small to medium doses, the drug solution was sucked into a syringe, and for large doses, it was injected through a hose.

When sucking a medicinal solution from a medicinal liquid container into a syringe, the user sucks in the amount of outside air into the syringe, and while the outside air is introduced into the medicinal liquid container, the medicinal liquid is alternately sucked into the syringe and replaced.

Another method is to open the mouth of the drug dispenser, insert a syringe needle, and suck it up. This method allows outside air to enter through the mouth of the drug dispenser, and countless amounts of dirty dust from the outside air enters with the drug solution, making it unsanitary.

(Problem to be solved by the invention) Hygiene is the first priority in medical care. For this reason, new sterilized instruments are used for syringes, which are disposable and thrown away after one use.Although the outside air is not completely clean, this is not considered important when using syringes.

Even if the instruments are sterile, there is a very high possibility that the countless amount of dirt in the outside air in the medical field will get into the drug solution, and it is impossible to use a drug solution that has been used for a long time. Therefore, the operator must be extremely careful. It was time consuming.

Therefore, if the syringe is filled with medicine from the beginning, it will be very convenient for the operator, but there will be a big problem in terms of hygiene.The present invention is a new medicine liquid container and syringe that solves the above problems. Aiming at Improving Medical Hygiene and Saving Labor (Means for Solving Problems) The present invention is configured as follows in order to achieve the above object.

In other words, when injecting, the problem is sucking out the drug solution from the drug dispenser, so in order for the drug dispenser to also function as a syringe, there will be no problems with sanitary preservation. There is no problem in keeping it alive and storing it.〈It is a conventional medicine liquid container, and in order to become a syringe, a partition rubber 4F is attached to the bottom or middle of the medicine liquid container 1, and a medicine liquid chamber 4 in which the medicine liquid is placed is attached.
6 and an outdoor air chamber 47 into which outside air enters, and in order to move this partition rubber 4, it is necessary to open the lower part of the drug container 1 and input energy into the outside air chamber 47 to push it. , or install an object that emits energy.

The former method is the means shown in FIGS. 1 to 10.

If the lower part of the chemical liquid container I is opened and energy is applied to push it, the outside air chamber 47 is not necessary, and therefore the partition rubber 4 is installed at the lower part of the chemical liquid container I.

In order to open the bottom part of the drug solution container 1, it is easy and clean, does not require any special tools, and in order to avoid discharging waste into the medical field, open the bottom part of the drug solution container 1 and apply energy. A boat awl 14 is attached to a pusher 15 that is moved by the pusher, and the lower part of the chemical liquid container 1 is cut open.

A pusher 15 is used to connect and move the partition rubber 4.

The latter are the means shown in Figs. 14 to 21. 6 The ball for installing the energy-generating object in the outside air chamber 47 is an elastic body, with a coil spring 48 in Fig. 14, a sponge rubber 49 in Fig. 15, The elastic body is installed in the outside air chamber 47 to push the partition rubber 4 to increase the internal pressure of the chemical chamber.

At this time, the partition rubber 4 cannot be pushed unless outside air enters, so insert the two outside air passage pipes with the intake needle 28. Place the bellows-shaped bag 50 in the outside air chamber 47, and then FIG. 16 shows a means for making compressed air hot and pressurized.

To the state shown in Fig. 16, coil spring 48 or sponge rubber 49
Fig. 17 and Fig. 18 show the means for further installing the temperature and pressure.

Place the bellows-shaped bag 50 in the outside air chamber 47, and put it inside.
Figures 19 and 20 show a method of placing a chemical and causing an expansion or foaming reaction.

Place the bellows-shaped bag 50 in the outside air chamber 47, and put it inside.
Install the air cylinder 58 and close the cylinder valve 60.
When opening, a valve opening arm 61 is attached to the valve 60, and a magnet 62 is further attached to the valve opening arm 61.

When the magnet 62 is moved outside the N lacquerware container 1 by another strong magnet, the magnet 62 moves the valve opening arm 61 and opens the valve 60 as shown in FIG.

If the drug is placed in a soft container, the medicinal solution will come out regardless of the outside air, so Fig. 11 shows a method in which the soft container is used as a syringe.

The medicine liquid container has a rubber stopper 2, so instead of using the conventional syringe needle, use a syringe needle 3 with a double-edged blade, one to pierce the medicine liquid container rubber stopper 2 and the other to pierce the living body. One means is shown in FIG.

If you insert the syringe needle 3 into the drug dispenser and pull the pusher 15 in the opposite direction, outside air will enter the drug dispenser and contaminate the drug solution.
To prevent this, use 3I of outside air between the two blades! FIG. 23 shows the means in which the cutoff valve 67 is installed.

Since the injection needle 3 has a double-edged blade, one for piercing the rubber stopper 2 of the drug liquid container and the other for piercing the living body, the blade for piercing the rubber stopper 2 of the drug liquid container is hidden by the stab stop 5 as shown in Fig. 24. It is.

In order to prevent outside air from entering the drug solution container and contaminating the drug solution when the injection needle 3 is inserted into the drug solution container, the drug solution container and the injection needle 3 are packaged in the same sterilized package as shown in FIG. 25 and 26.
It is a diagram.

(Function) In Fig. 2 of the M1 diagram, when the medicine liquid container of the main body and the pusher 15 are connected and the medicine liquid is put into the blood vessel, the outside air 3
+! If the injection needle 3 without the valve 67 is used in a pond, the medicine liquid container and the injection needle 3 are packaged in the same sterilized package.
It is more hygienic to use the injection needle 3 equipped with the outside air cutoff valve 67.

There is a drug dispenser containing an elastic body, from which a drug solution comes out when a syringe needle 3 is inserted into the drug dispenser.

These are the chemical liquid containers shown in Figures 14 to 18.

When the medicinal liquid in these medicinal liquid containers is used in a conventional syringe, the medicinal liquid enters the syringe from the side, so there is no contamination of the outside air.

If you want to use this medicine liquid container as a syringe to give additional injections to living organisms or intravenous drip injections, attach a connecting hose between the injection needle inserted into the medicine liquid container and the injection needle inserted into the living body, and fold the connecting hose. While adjusting the presser foot, use the pressure from the drug dispenser to inject additional injections into the biological body or the intravenous injection.

Even in a drug dispenser containing an elastic body, there is a drug dispenser in which the drug solution does not initially come out even when the injection needle 3 is inserted.

When the coil spring 48 is made of a shape memory alloy and used in the chemical liquid dispenser shown in FIGS. 14 and 18, it becomes an elastic body by putting it in a memory recall state.

In the chemical liquid containers shown in FIGS. 19 and 20 as well, the internal pressure of the chemical liquid chamber 46 increases after the chemical reaction occurs.

The chemical liquid container shown in FIG. 21 has a valve 60 of a compressed air cylinder 58.
is transferred using a magnet, and when the valve 60 is opened, the chemical liquid chamber 46 is opened.
The internal pressure of increases.

Oral drug administration must be done with great care and hygiene.

Compared to traditional syringes, hygiene is much improved.

Treatment can be performed in a hygienic and labor-saving manner by minimizing the effort required to draw medicine from a liquid dispenser into a syringe and the countless amounts of contaminated outside air at medical sites.

Since the lower part of the medicine liquid container as shown in FIG. 1 is opened and used as a syringe, resources are saved, and the amount of waste generated in the conventional medicine liquid container is reduced.

Not only is it sanitary and labor-saving, it is also economically improved.

When connecting the drug dispenser to the pusher, the boat awl gets rounded with debris and no awl waste is left in the medical field.

Easy to clean and requires no special tools.

A drug dispenser equipped with an elastic body or the like allows treatment to be carried out in a hygienic and labor-saving manner by minimizing the amount of polluted outside air required for additional intravenous injections or intramuscular injections.

Even with conventional syringes, medical liquid containers equipped with elastic bodies or the like can minimize outside air and provide sanitary and labor-saving treatment.

The injection needle that prevents the inflow of outside air does not damage the drug solution, so treatment can be performed in a sanitary and labor-saving manner.

If the medicine container and the injection needle are packaged in the same package, the treatment can be performed in a more sanitary and labor-saving manner.

If a medicine container and a large number of outside air inflow prevention injection needles are packaged in the same sterilized package, they can be used for preventive injections, etc., thereby improving public health.
