Abstract
The invention relates to a medical appliance, in particular to a perforator for a bottle stopper of a transfusion device. The bottle stopper perforator consists of a perforating pipe, a perforating pipe seat and an air filter. The bottle stopper perforator is characterized in that the perforating pipe is hollow; a perforating end of the perforating pipe is a closed cusp; the side surface of the perforating pipe is provided with at least one opening; the opening at the lower end of the perforating pipe is connected with the puncturing pipe seat that is internally provided with a liquid passage and a gas passage; one end of the gas passage is communicated with the air filter; the other end of the gas passage extends into the puncturing pipe to form an extension section; an opening of the extension section is at least higher than the lower edge of a lowest opening on the side surface of the perforating pipe; and the extension section and the perforating pipe are communicated with the liquid passage of the perforating pipe seat by clearances. The bottle stopper perforator with the structure has low perforating resistance and moderate cost, can be assembled easily, can realize automation easily, and has good sealing performance and low using risk.
Description
Technical field
The present invention relates to a kind of medical apparatus, be specially the bottle plug puncture unit of transfusion device head.
Background technology
At present domestic bottle plug puncture unit in use mainly contains two classes.
The first kind is the plastics perforator, and is simple in structure, and cost is low, but side by side gas passage and fluid passage in its puncture tube, and caliber is very thick, and penetration Resistance is big, and exists the medicine bottle bottle stopper to be punctured to break and cause the risk of leakage.
Second class is the metal puncture device, especially fitst water with metallic sheath tubular type perforator, have single puncture and the low advantage of resistance, but because sleeve pipe mode, generally by internal and external pin and up and down needle stand totally 4 parts constitute, have the cost height, assemble time-consumingly, leakage even bubble were sneaked into shortcomings such as fluid passage when the connecting portion sealing can't guarantee to cause infusing.
Summary of the invention
At the problems referred to above, the object of the present invention is to provide a kind of bottle plug puncture unit, to solve the problem that present technology exists.
For achieving the above object, be achieved through the following technical solutions:
A kind of bottle plug puncture unit, form by puncture tube, puncture base and air filter, it is characterized in that described puncture tube hollow, cutting tip is the sealing tip, there is at least one hole the side, its lower ending opening connects the puncture base, puncture base inside has fluid passage and gas passage, its gas passage one end is communicated with air filter, the other end extends to form the extension in puncture tube, the extension opening is higher than the lower limb of the minimum hole in puncture tube side at least, and extension and puncture tube gap are communicated with the fluid passage of puncture base.
Described puncture tube side has only 1 hole, and puncture base extension opening is higher than this hole lower limb, the ventilation of hole upper end, and the hole lower end leads to liquid.
There are 2 holes up and down described puncture tube side, and puncture base extension opening is higher than hole lower limb down, last hole ventilation, and following hole leads to liquid.
Present relatively technology, the present invention has the following advantages:
1, penetration Resistance is lower than shaped plastics perforator, and is the same with metallic sheath cast perforator.
2, two parts are only arranged, though cost is lower than metallic sheath cast perforator than shaped plastics perforator height.
3, two parts are only arranged, assembling is simple, realizes automatization easily.
4, connect between two parts and can adopt at present the most stable epoxide-resin glue legal, the probability of leakage is well below metallic sheath cast perforator, significantly reduced the risk that leakage in the infusion process or bubble are sneaked into fluid passage input human body.

Fig. 2 is another embodiment of the present invention structural representation
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described further.
As shown in Figure 1, a kind of bottle plug puncture unit comprises puncture tube 1, puncture base 2 and air filter 3.It is characterized in that puncture tube 1 head has sealing tip 11, the side has hole 12, lower ending opening 13 connects puncture base 2, puncture base 2 inside have fluid passage 21 and gas passage 22, gas passage one end 23 is communicated with air filter 3, the gas passage other end extends to form extension 24 in puncture tube, extension 24 openings are higher than the lower limb of hole 12, and the gap 4 of extension 24 and puncture tube 1 is communicated with the fluid passage 21 of puncture base 2.During use, gas enters the gas passage 22 and the extension 24 of Paracentesis needle holder 2 after filtering from air filter 3,24 opening is discharged from the extension, the upper end of the lateral apertures 12 by puncture needle 1 enters medicine bottle, and medicinal liquid enters from the lower end of the lateral apertures 12 of puncture needle 1, by the gap 4 of extension 24 and puncture tube 1, enter the fluid passage 21 of puncture base 2.
As shown in Figure 2, the another kind of embodiment of bottle plug puncture unit comprises puncture tube 1, puncture base 2 and air filter 3.It is characterized in that puncture tube 1 head has sealing tip 11, the side has last hole 121 and following hole 122, lower ending opening 13 connects puncture base 2, puncture base 2 inside have fluid passage 21 and gas passage 22, gas passage one end 23 is communicated with air filter 3, the gas passage other end extends to form extension 24 in puncture tube, extension 24 openings are higher than the lower limb of hole 122 down, and the gap 4 of extension 24 and puncture tube 1 is communicated with the fluid passage 21 of puncture base 2.During use, gas enters the gas passage 22 and the extension 24 of Paracentesis needle holder 2 after filtering from air filter 3,24 opening is discharged from the extension, enter medicine bottle by hole 121 on the side of puncture needle 1, and medicinal liquid hole 122 under the side of puncture needle 1 enters, by the gap 4 of extension 24 and puncture tube 1, enter the fluid passage 21 of puncture base 2.
