Medical closed ampoule bottle

Abstract

The invention discloses a medical closed ampoule bottle. The medical closed ampoule bottle is characterized in that an upper bottle opening and a lower bottle opening which are opposite to each otherare formed in a bottle body; the upper bottle opening is provided with a sealing cover, and a piston made of a flexible material is arranged in the lower bottle opening; when liquid medicine in the bottle cavity is sucked from the upper bottle opening, the piston can slide to the upper bottle opening along the inner wall of the bottle body. The medicine closed ampoule bottle has the advantages that it can be avoided that when a nurse breaks an ampoule bottle by holding the ampoule bottle with great strength, the ampoule bottle is likely to fracture, and consequently liquid medicine is wasted;it can be voided that when the ampoule bottle fractures, the hands of the nurse are punctured; it can be avoided that when the ampoule bottle fractures, glass fragments fall into the liquid medicine,and then the liquid medicine is drawn into an injector and injected into the human body; it can be avoided that when the nurse exerts excessive strength, a needle of the injector strikes the bottom, and consequently the needle may curve and cause harm to a patient; it can be avoided that dust, haze, germs and viruses in the air fall into the liquid medicine; it can be avoided that droplets or secreta possibly generated when the nurse breaking the ampoule bottle sneezes enters the liquid medicine and causes contamination. The medical closed ampoule bottle is simple in structure, convenient to operate, high in safety and suitable for storing injection liquid or injection powder.

Description

technical field [0001] The invention relates to a medical ampoule, in particular to a medical closed ampoule bottle. Background technique [0002] 1. The glass ampoule (hereinafter referred to as "background technology one") before the 1980s was bullet-shaped or rocket-shaped. When extracting the liquid in the ampoule, most of them used tweezers to crush the ampoule head, opened the ampoule first and then sucked it Liquid medicine, its defect is: [0003] (1) Inadvertent operation often causes the ampoule body to break and the medicine to spill all over the floor. [0004] (2) Even if the ampoule body is intact, glass shards often fall into the liquid medicine. Small glass shards (such as 50% glucose injection is relatively viscous) are often sucked into the syringe along with the liquid medicine and large needles and then Inject into the human body. In particular, intravenous injection can cause pulmonary infarction; in some medical accidents, even doctors and nurses do ...

AI Technical Summary

Problems solved by technology

[0003] (1) Inadvertent operation often causes the ampoule body to break and the medicine to spill all over the floor

[0004] (2) Even if the ampoule body is intact, glass shards often fall into the liquid medicine. Small glass shards (such as 50% glucose injection is relatively viscous) are often sucked into the syringe along with the liquid medicine and large needles and then Inject into the human body

Especially intravenous injection can cause pulmonary infarction; some medical accidents, even doctors and nurses do not know the real cause of death

[0005] (3) After the head of the ampoule is broken, the medicinal liquid in the ampoule is exposed to the atmosphere, and the wind, dust, floating dust, bacteria, and viruses in the atmosphere are in danger of falling into the medicinal liquid

[0006] (4) Some nurses, especially nurses in primary medical institutions, often operate, exhale, talk or sneeze without wearing masks, which will cause germs, viruses, mycoplasma, etc. in the mouth and respiratory tract to cause infection. The pathogenic microorganisms are directly sprayed into the medicine liquid in the ampoule to cause pollution

[0007] (5) Nurses often insert the syringe needle into the bottom of the ampoule to suck out the liquid medicine in the ampoule. If the force is not appropriate, the needle tip will curl, and then injecting with this needle will increase the pain of the patient.

In particular, intravenous injection and needle withdrawal can cause scratches on the inner wall of the vein, causing cord-like thrombus in the vein and subcutaneous ecchymosis. If the patient does not massage the wound properly, there is a risk of thrombus falling off and pulmonary infarction

[0008] (6) For medical institutions, it will cause the environment to be polluted by glass shards and debris

[0011] (2) The glass shards produced when the neck of the ampoule breaks will still fall into the medicinal liquid in the inner cavity of the ampoule

[0012] (3) The method of opening the ampoule is still open, and the liquid medicine in the ampoule still has the risk of being polluted by dust, foreign matter, germs, viruses, and small insects in the atmosphere

[0013] (4) There is still the problem of curling the needle tip of the syringe

[0014] Three, the patent application number is 200480009701.6, the publication number is CN1771018A, and the defect of the ampoule (hereinafter referred to as "background technology three") on May 10, 2006 is: it is still an open way of taking liquid, and the ampoule suction container When part (12) is the medicinal liquid in the bottle body, the atmosphere will still enter the inner cavity of the container part 12, such as nurse's droplets, sneezing, coughing, dust haze in the atmosphere, foreign matter, germs, viruses, small insects, etc. Risk of contaminating the liquid medicine in the container part 12

[0016] (1) The nurse usually inserts the needle of the syringe into the bottom of the ampoule and injects water for injection or sodium chloride injection. Aspirate cleanly; the problem is that improper or excessive force can cause the needle tip to curl, which is a very common problem when nurses are busy

[0017] (2) Since the medicinal powder occupies a certain space in the inner cavity of the ampoule bottle, the inner cavity of the ampoule bottle will generate negative pressure in the latter period of time after the liquid medicine is sucked, which in turn will cause a short circuit for taking liquid as described in "Background Technology 3" (applicant Think it's difficult to breathe)

The nurse will pull out the syringe needle, and then suck air into the cavity of the ampoule to increase the pressure in the cavity of the ampoule to facilitate the extraction of the liquid medicine. There are two problems: ① Repeated puncture of the rubber sealing cap of the ampoule is easy to produce cap debris, There is a danger of tiny bottle cap debris being sucked into the syringe and injected into the human body with the liquid medicine; ② In order to avoid the adverse effects of preservatives on the human body, or to extend the shelf life of some injection medicines, some pharmaceutical institutions use vacuum ampoules to Storage of medicines for injection (powder); the problem is that it is difficult to suck the dissolved medicine from the ampoule, and it needs to inject an appropriate amount of air to make the operation of pumping the medicine smooth; not only are there many operating procedures, but also A bit similar to the defect of open suction liquid medicine
