Detailed Description

The present invention is further described with reference to fig. 1-2.

The utility model provides a bottle insertion puncture outfit which characterized in that: comprises a base 1, an upper cover 5, a lower cover 2, a puncture needle 6 and a filter screen 4. The base 1 has a partition 11 therein to divide the interior of the base 1 into an upper chamber 12 and a lower chamber 13. An upwardly extending filter tube 3 is formed on the bottom wall of the upper chamber 12, i.e., the partition 11, the upper end of the filter tube 3 is closed and the lower end is opened, and a plurality of filtrate ports 31 are formed on the side wall of the filter tube 3, and each of the filtrate ports 31 is higher than the bottom wall of the upper chamber. The filter screen 4 is assembled in the upper chamber through a filter screen cover 41 and is positioned in a position close to the upper chamber opening, and the liquid medicine entering the upper chamber is filtered. The upper cover 5 is assembled on the upper opening of the upper chamber, and the inner cavity 51 of the upper cover 5 is communicated with the upper chamber of the base 1, and the side wall of the upper cover 5 is provided with a liquid inlet 52. The lower end of the puncture needle 6 is inserted and fixed in a positioning tube on the partition plate 11, and the upper end of the puncture needle passes through the top of the upper cover 5. The lower cover 2 is clamped on the lower cavity opening of the lower cavity 13, an air inlet valve 22 and a liquid outlet pipe 21 are integrally formed on the lower cover, the air inlet valve 22 is communicated with the lower end opening of the puncture needle 6, an air filtering membrane 221 is arranged on the air inlet valve 22, and the liquid outlet pipe 21 is communicated with the lower end opening of the filtering pipe 3.

Based on the structure, the utility model specifically works as follows: the lower end of the liquid outlet pipe 21 is connected with a transfusion pipe, and the upper end of the puncture needle 6 is inserted into the medicine bottle; the liquid medicine in the medicine bottle flows out through the liquid inlet 52, the inner cavity 51 of the upper cover 5, the upper cavity of the base 1, the filter tube 3, the liquid outlet tube 21 and the infusion tube; meanwhile, in order to ensure the stable air pressure in the medicine bottle, external air enters the medicine bottle through the air valve 22 and the puncture needle 6. In the process, when the liquid medicine enters the upper chamber, the liquid medicine needs to pass through the filter screen 4, so that the filter screen 4 can carry out first filtering on the liquid medicine so as to filter bubbles and particles in the liquid medicine; secondly the liquid medicine is when process filter tube 3, because the filtrating mouth 31 of filter tube 3 is located the lateral wall of filter tube 3, consequently even there is the bubble behind filter screen 4, when passing through filtrating mouth 31, also can be crowded garrulous by filtrating mouth 31, or can't lead to filtrating mouth 31 and remain in the upper chamber, reach the effect of getting rid of the filtrating bubble, simultaneously because filtrating mouth 31 is higher than the diapire of upper chamber, can effectively avoid last remaining liquid to pass through filtrating mouth 31 and enter into in drain pipe 21, and most granule dregs are in this remaining liquid, consequently this structure can reach apparent filter effect.

The integrated forming has pneumatic valve 22 and drain pipe 21 on lower cover 2, under this structure, can promote the degree of fit of lower cover 2 on the port under base 1, under the condition of convenient assembly, can also promote the leakproofness after the assembly, reduces the possibility of weeping.

Specifically, the lower end of the upper cover 5 is provided with the conical bayonet 54, the upper cover 5 is clamped on the upper end wall of the base 1 through the conical bayonet 54, the upper end of the lower cover is clamped through the conical bayonet 54, the upper end of the lower cover can be assembled with the upper end of the base 1, meanwhile, under the gradient of the conical structure, an effective sealing effect can be achieved, and the possibility that liquid medicine overflows from the position between the base 1 and the upper cover 5 is reduced. Furthermore, in order to improve the stability of the assembly of the upper cover 5 on the base 1, the inner wall of the tapered bayonet 54 is provided with a clamping groove 53, the outer side wall of the base 1 is provided with a clamping strip 15 clamped with the clamping groove 53, and the outer side wall of the base 1 is formed with an outer step 14 for the lower end of the upper cover 5 to abut against.

A clip 212 is formed on the outer side wall of the lower cover, and a clip groove for clipping the clip 212 is formed on the inner wall of the lower chamber 13. The structure can facilitate the clamping of the lower cover 2 on the lower end of the base 1 and can also ensure the tightness after the clamping.

The lower extreme of drain pipe 21 is screwed joint 211, and this structure can be convenient for the connection or the dismantlement of transfer line, can also guarantee the leakproofness under the connection status simultaneously.

The upper cover, the base 1, the lower cover and the filter screen 4 are made of the same PVC material, so that the same recovery and treatment in the later period of the utility model are facilitated.
