Detailed Description

The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.

In the description of the present invention, it is to be understood that the terms "inner", "outer", "left" and "right" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

The first embodiment is as follows:

the invention discloses a medicine dispenser as shown in figures 1-4, wherein an adapter part 1 made of elastic material is arranged above the medicine dispenser, a temporary storage part 10 is communicated below the adapter part, a partition plate 9 for dividing the temporary storage part into an upper part and a lower part is arranged at the middle position of the temporary storage part, and a first one-way valve 5 is arranged at the middle position of the partition plate, so that liquid medicine can only flow into the upper space from the lower space of the temporary storage part and flows out from the adapter part through a first interface of the temporary storage part to be input into an injector without flowing back. The temporary storage portion right side sets up parallel to each other and independent second interface and third interface, and wherein the second interface is located the temporary storage portion top, and the third interface is located the temporary storage portion below, and two interfaces all communicate with the filter house, and this filter house is hydrophobic filter, can filter the gas that gets into in the bottle and purify, reduces external pollution. A second one-way valve 6 is arranged between the second interface and the filtering part, a third one-way valve 8 is arranged between the filtering part and the third interface, and a filter screen 7 is arranged between the third one-way valve and the filtering part. The passing direction of the second one-way valve is opposite to that of the third one-way valve, namely, the gas can only enter the filtering part from the upper part of the temporary storage part and then enter the lower part of the temporary storage part and cannot flow back. The fourth interface is arranged below the temporary storage part and is communicated with the liquid taking part 4, the liquid taking part is a double-channel pricking pin, and the double-channel pricking pin can effectively transfer liquid and maximize the amount of the liquid to be drawn. The protection sleeve is arranged outside the double-channel puncture needle to prevent external microorganisms from invading to cause infection, and the protection sleeve is made of elastic materials and can be tightly contacted with the puncture needle to ensure the sealing property.

The axis of the first interface, the axis of the first one-way valve, the axis of the fourth interface and the axis of the liquid taking part are all coaxially arranged, so that a direct-flow liquid passage can be provided without bending, the integrity of blood cells cannot be damaged when blood or blood products are infused, and the risk of hemolysis is reduced.

The liquid taking part is externally provided with a connecting seat 3 which is used for fixing the dispensing device and the penicillin bottle 12 and has a sealing effect, the connecting seat is also of an elastic shell structure, the elastic structure can adapt to penicillin bottles of various types and specifications, and the universal type is strong.

All parts in the device are made of transparent materials, and the purpose is to facilitate observation of liquid flow direction and removal of abnormity.

The length of the puncture needle in the device is far less than that of a common syringe needle, and the puncture needle channel has a diameter larger than that of the syringe needle because the specifications of the penicillin bottles are different and the tail end of the puncture needle is preferably positioned at the bottleneck when the penicillin bottle with the minimum specification is inserted.

When the device is used, the penicillin bottle 12 is wiped by alcohol and dried; taking down the protective sleeve at the top of the puncture needle, holding the medicine dispenser and inserting the puncture needle into the penicillin bottle to ensure that the medicine dispenser and the puncture needle enter vertically without inclination or toppling; the pricking pin is completely inserted into the penicillin bottle, the fixing seat is in close contact with a bottle body of the penicillin bottle, the dispensing device is fixed on the bottle body, the adapter part is wiped clean and dried by alcohol, the syringe 11 without the needle head is inserted into the adapter part 1, the adapter part is elastically deformed and is tightly connected with the front end of the syringe, the piston of the syringe is pushed forwards, air is pumped into the penicillin bottle 12 through the temporary storage part 10 and the filtering part 2, the penicillin bottle is inverted, and the piston is pulled to take out required amount of liquid medicine.

Example two:

this embodiment discloses a medicine dispenser for disposing freeze-dried powder, the installation direction of first check valve 5, second check valve 6 and third check valve 8 is opposite in first embodiment in this medicine dispenser, promptly this medicine dispenser is when using, directly squeezes into the xiLin bottle through first check valve 5 with the liquid in the syringe, then inhales the filter 2 with the mixed liquid in the xiLin bottle through third check valve 7, and the liquid after the filtration gets into temporary storage portion 10 through second check valve 6, gets into in the syringe through switching portion 1 at last.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the application. Thus, the present application is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
