Above-mentioned spike 10 in use; puncture portion 121 is utilized to puncture plug on medicine bottle; but; because puncture portion 121 is in said structure; it is in the process puncturing plug; usually the woollen that existing breaks plug drops is brought into the risk in medicinal liquid, time serious, patient's blood vessel can be caused to block.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of novel infusion perforator, and it can effectively prevent woollen from entering medicinal liquid.
For achieving the above object, this utility model adopts following technical scheme:
Novel infusion perforator, comprises,
Handheld Division;
Be positioned at the liquid outlet on Handheld Division and air inlet;
Be connected to the cross-under pipe of front end, Handheld Division, the front end of this cross-under pipe forms a puncture portion, the taper that puncture portion increases gradually in diameter from front to back, the side line of puncture portion axial cross section is curved, and the surface in puncture portion and cross-under pipe front end seamlessly transit, wear nozzle interior and form mutually isolated fluid passage and gas passage, one end of gas passage is communicated with air inlet, the other end extends to the formation gas outlet, side in puncture portion, the side in puncture portion at least has two inlets around the axial array in puncture portion, one end of fluid passage is communicated with this at least two inlets, the other end is communicated with liquid outlet.
Inlet is arranged on the diapire of the deep gouge that surface, puncture portion is offered.
An air-filtering membrane is provided with in air inlet.
Fluid passage and gas passage are by the curved barrier partitions in the cross section of wearing nozzle interior.
The beneficial effects of the utility model are:
Compared to prior art, this utility model due to puncture portion be the taper of level and smooth cambered surface in surface, therefore, when puncture portion punctures plug, regular the breaking of breach of plug, avoid plug woollen to drop, thus effectively prevent plug woollen to enter medicinal liquid, improve the safety of intravenous drip.
Accompanying drawing explanation
The structural representation of the existing spike of Fig. 1;
Fig. 2 is the structural representation of this utility model spike;
Fig. 3 is sectional view of the present utility model;
Fig. 4 is the A direction view of this Fig. 2;
Wherein: 20, Handheld Division; 30, cross-under pipe; 31, puncture portion; 311, gas outlet; 312, inlet; 32, fluid passage; 33, gas passage; 40, liquid outlet; 50, air inlet.
Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, this utility model is described further:
As Fig. 2, 3, 4, for a kind of spike of the present utility model, it comprises Handheld Division 20, cross-under pipe 30, be arranged on the liquid outlet 40 of Handheld Division 20 tail end, and be arranged on the air inlet 50 of side, Handheld Division 20, wherein, Handheld Division 20 is as the base component of whole spike, it is in use so that operator's hands is held, cross-under pipe 30 is connected to the leading section of Handheld Division 20, the front end of cross-under pipe 30 forms a puncture portion 31, the taper that puncture portion 31 increases gradually in diameter from front to back, the axial cross section side line in puncture portion 31 is camber line, and, the position that the afterbody on surface, puncture portion 31 is connected with cross-under pipe 30 front end seamlessly transits, the inside of cross-under pipe 30 forms fluid passage 32 and the gas passage 33 of isolation mutually, one end of gas passage 33 is communicated with air inlet 50, the side that the other end extends to puncture portion 31 forms a gas outlet 311, the side in puncture portion 31 has three inlets 312, the axial array of these three inlets 312 around puncture portion 31, that is, angularly distribute in face, a sector at these three inlets 312, this face, sector is just just to above-mentioned fluid passage 32, one end of aforesaid liquid passage 32 is communicated with three above-mentioned inlets 312, the other end is communicated with liquid outlet 40.
This utility model in use, puncture portion 31 is utilized to puncture plug on medicine bottle, medicinal liquid in medicine bottle enters into fluid passage 32 respectively from three inlets 312, then fluid passage 32 of postponing flows out from liquid outlet 40, meanwhile, outside gas is through air inlet 50, and gas passage 33 of postponing enters in medicine bottle from gas outlet 311, pressure in equalizing vial, multiple inlet 312 effectively can play the effect of shunting; When puncture portion 31 punctures plug, because puncture portion 31 is the taper that surface is level and smooth cambered surface, therefore, regular the breaking of breach of plug, avoid plug woollen to drop, thus effectively prevent plug woollen to enter medicinal liquid, improve the safety of intravenous drip.Here it should be noted that, above-mentioned inlet 312 quantity of the present utility model can be determined according to the diameter of cross-under pipe 30, its quantity can be specifically two also can be greater than three, in a word, no matter be arrange how many inlets 312, all inlets 312 are all the axial array around puncture portion 31.
Drop to avoid plug woollen further, above-mentioned inlet 312 can be arranged on the diapire of the deep gouge on surface, puncture portion 31, that is, thus, effectively avoid inlet 312 and produce because machining accuracy is difficult to control the phenomenon protruding from surface, puncture portion 31.
Certainly, in order to prevent the impurity in extraneous air from entering into medicine bottle internal contamination medicinal liquid, in above-mentioned air inlet 50, an air-filtering membrane is provided with.
In this utility model, fluid passage 32 and gas passage 33 mutually isolated by arrange in cross-under pipe 30 inside baffle plate realize, the cross section of this baffle plate is curved, and the part shape gas passage 33 that curved baffle surrounds, cross-under pipe 30 is not then formed fluid passage 32 by the part that curved baffle encloses.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of this utility model claim.
