AI Technical Summary
The existing puncture device has too small a height difference between the fluid outlet and the air inlet, resulting in insufficient fluid outflow pressure. Medical staff need to manually squeeze the drip chamber to drain the fluid, which is troublesome and time-consuming.
A liquid inlet and an air inlet are designed on the side of the tip of the puncture device. The height difference is increased by oblique cutting, and a relative depression is formed on the outer wall to reduce puncture resistance. The air inlet channel is L-shaped to slow down the air flow and promote the dissolution of air bubbles.
It increases the rate of fluid outflow, reduces the number of steps required for medical staff, and improves work efficiency.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to a puncture ware field, concretely relates to a novel plastic puncture ware. BACKGROUND
[0002] The inlet of the puncture ware is used for allowing external air to enter so as to promote liquid to be discharged, and the liquid outlet is used for liquid to flow out. The existing puncture ware has the problems of small liquid outlet pressure and difficult liquid in a medicine bottle to flow out due to the small height difference (about 2.37 mm) between the liquid outlet and the inlet. SUMMARY
[0003] In view of the above problems of the prior art, the utility model aims to provide a novel plastic puncture ware with a reasonable structure.
[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme:
[0005] A novel plastic puncture ware comprises a puncture ware main body, the puncture ware main body is internally formed with a liquid outlet channel and an air inlet channel, one end of the liquid outlet channel penetrates through the puncture ware main body tip side surface to form a liquid outlet, and one end of the air inlet channel also penetrates through the puncture ware main body tip side surface to form an air inlet; characterized in that the liquid outlet and the air inlet are increased in height difference by being beveled on the outer wall of the liquid outlet.
[0006] Preferably, the height difference between the liquid outlet and the air inlet is 4.68 mm.
[0007] Preferably, recesses are formed on the outer wall of the puncture ware main body and on the opposite sides, and the recesses are not communicated with the liquid outlet channel and the air inlet channel. This design can reduce the puncture resistance.
[0008] Preferably, the air inlet channel is L-shaped. The L-shaped design can slow down the air flow rate and promote bubble dissolution.
[0009] Compared with the prior art, the utility model has the beneficial effects as follows:
[0010] The utility model increases the height difference between the liquid outlet and the air inlet, thereby increasing the pressure difference between liquid outflow and air inlet, effectively promoting the rapid outflow of liquid, eliminating the operation of medical staff to squeeze the drip chamber to drain, and improving the work efficiency. BRIEF DESCRIPTION OF DRAWINGS
[0011] Figure 1 The utility model structural schematic diagram is shown in the figure;
[0012] Figure 2The utility model discloses a structure section view schematic drawing. PREFERRED EMBODIMENT
[0013] The utility model makes further elaboration in combination with the drawings, and the part that is not elaborated below is according to the prior art and the conventional knowledge in the field.
[0014] As Figure 1 , Figure 2 The utility model discloses a novel plastic puncture ware, including puncture ware main part 1, the liquid outlet channel 2 and the air inlet channel 3 are formed in puncture ware main part 1, and the air inlet channel is L type, and L type design can slow down air velocity, promotes the bubble dissolution. And the liquid outlet channel 2 one end penetrates the side of puncture ware main part 1 tip to form liquid outlet 4, and the air inlet channel 3 one end also penetrates the side of puncture ware main part 1 tip to form air inlet 5, and liquid outlet 4 and air inlet 5 are all beveling, and further beveling on the outer wall of liquid outlet to make the height difference A of liquid outlet lower end and air inlet lower end increase to 4.68mm.
[0015] Form recessed on the outer wall of puncture ware main part 1 tip and the two sides opposite, and recessed 1.1 and liquid outlet channel, air inlet channel all are not connected, recessed design is carried out on two sides, can reduce the puncture resistance.
