Embodiment 1

[0019] In order to solve the problem that the multifunctional negative pressure dispensing device in the prior art requires repeated insertion and withdrawal of the needle, which is inconvenient to use, and more exposed to air, is prone to infection. The present invention provides a device such as figure 1 The multifunctional negative pressure dispensing device shown includes a bottle body for storing medicinal liquid, the bottle body is a compressed elastic bottle 1, a base 2 is arranged above the mouth of the compressed elastic bottle 1, and a base 2 is arranged above the base 2 The needle holder 3, the needle holder 3 includes a sleeve 17 arranged above the base 2, and a liquid passage 18 arranged in the middle of the sleeve 17, the inner wall of the sleeve 17 is provided with internal threads, and the height of the liquid passage 18 is higher than The height of the sleeve 17 is such that the liquid channel 18 will extend out of the sleeve 17, which is convenient to be conne...

Embodiment 2

[0024] On the basis of Example 1, such as figure 2 As shown, the bottom surface of the compressed elastic bottle 1 is also provided with a second needle base 9, the second needle base 9 is connected with a second injection needle 10, and the second injection needle 10 is also provided with a second elastic compression sleeve 11 , the second injection needle 10 is also sheathed with a second needle sheath 12, and the elastic compression sleeve 5 and needle sheath 6 sheathed on the injection needle 4 have the same function.

[0025] With this structure, there is no need to store the medicine in the compressed elastic bottle 1. When in use, according to the actual dispensing needs, one end is inserted into the dilution liquid, and the other end is inserted into the liquid bottle that needs to be proportioned. If necessary, it can be inserted between the needle seat and the injection needle. A one-way valve is added in between to determine the flow direction of the drug or dilute...

Embodiment 3

[0027] Different from Examples 1 and 2, the solution of the multifunctional negative pressure dispenser provided in this example is that a compression auxiliary part is arranged on the outside of the compressed elastic bottle 1, such as image 3 As shown, the compression auxiliary part includes a syringe 14, and a push rod 15 matched with the syringe, the bottom surface of the compressed elastic bottle 1 is provided with a groove 13, and the inner wall of the groove 13 is provided with a second internal thread, so The top of the push rod 15 is provided with a protruding head 16 , and the outer wall of the protruding head 16 is provided with a second external thread, and the groove 13 is threadedly connected with the protruding head 16 .

[0028] This design scheme can also complete aseptic and fast dispensing work, and the cooperation between the designed groove 13 and the protrusion 16 can completely discharge the medicine in the compressed elastic bottle 1 without causing a l...

Abstract

The invention belongs to the technical field of medical apparatus, and in particular relates to a multifunctional negative-pressure dispensing apparatus; without inserting and withdrawing a needle repeatedly, medicines can be preserved in the multifunctional negative-pressure dispensing apparatus in a vacuum environment in advance; when the medicines need to be dispensed and used, a vacuum jacket is opened and diluting liquid is injected into the multifunctional negative-pressure dispensing apparatus for dispensing and using, so that an opportunity of getting into contact with external air is reduced and the circumstance of bacterium or germ infection is greatly avoided; moreover, the multifunctional negative-pressure dispensing apparatus is convenient and simple to use, and the dispensing apparatus is capable of completing dispensing just by inserting and withdrawing the needle once; and in addition, the multifunctional negative-pressure dispensing apparatus can also serve as a blood collector, so as to provide convenience for the blood collecting therapy of patients.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a multifunctional negative pressure medicine dispenser. Background technique [0002] As we all know, the inpatient department of a hospital needs to prepare different types and proportions of medicinal liquids for injection and infusion for each patient according to the doctor's prescription. Since it is related to life and health, the liquid preparation work is very important. At present, the dispensing work in hospitals is performed manually by nurses using disposable syringes. During the dispensing process, it is necessary to continuously pull and push the plunger of the syringe to complete the work, and the labor intensity of the operators is relatively high. Due to the diversity of drugs, the process of dispensing often involves the mixing of drugs in various packaging forms, such as ampoules, vials, infusion bags, etc. Among them, ampoules and vials can...
