Abstract
This utility model discloses a kind of deep vein puncture needle with pressure tester, comprise piercing needle and syringe, this syringe is made up of syringe and piston, syringe cavity is formed between piston and syringe, also comprise the pressure tester being arranged on described piston rear end, this pressure tester is communicated with syringe cavity by pipeline, or, also comprise the pressure tester being arranged on described piercing needle and syringe junction, this pressure tester communicates with piercing needle inner chamber.This utility model structure is simple, easy to use, can effectively improve deep vein puncture success rate, reduces arterial injury probability and degree, reduces the misery of patient.
Description
Technical field
This utility model relates to field of medical technology, specifically a kind of deep vein puncture needle of the band measuring device for deep venouspuncture.
Background technology
Clinically, for carrying out major operation or intensive care patient needs to carry out massive transfusion transfusion, central venous pressure monitoring, heart function monitoring, row deep venouspuncture is therefore needed.The position of deep vein puncture mainly contains internal jugular vein, subclavian vein and femoral vein.These veins all accompany row with tremulous pulse, be therefore that constant error is through tremulous pulse carrying out deep vein puncture.Distinguish that arteriovenous method is insert a syringe needle in the hole that puncture needle afterbody puts seal wire at present, observe and whether have blood to flow out.If there is blood to flow out, judge that needle point is positioned at intra-arterial, if needle point depletion of blood liquid stream goes out, think needle point not at intra-arterial.This mode complex operation, often departs from blood vessel because these operations cause puncture needle needle point to move, causes puncture failure.
Utility model content
For above-mentioned the deficiencies in the prior art, the purpose of this utility model proposes a kind of deep vein puncture needle with measuring device, and simple to operate, puncture success rate is high, can avoid the further damage to tremulous pulse.
Technical solution of the present utility model is as follows:
A kind of deep vein puncture needle with pressure tester, comprise piercing needle and syringe, this syringe is made up of syringe and piston, syringe cavity is formed between piston and syringe, its feature is, also comprise the pressure tester being arranged on described piston rear end, this pressure tester is communicated with syringe cavity by pipeline.
The spring being provided with piston in described pressure tester and being connected with this piston, the sidewall of described pressure tester is also provided with pressure labelling.
Another kind of deformation technology scheme of the present utility model is as follows:
A kind of deep vein puncture needle with pressure tester, comprise piercing needle and syringe, this syringe is made up of syringe and piston, syringe cavity is formed between piston and syringe, its feature is, also comprise the pressure tester being arranged on described piercing needle and syringe junction, this pressure tester communicates with piercing needle inner chamber.
The spring being provided with piston in described pressure tester and being connected with this piston, the sidewall of described pressure tester is also provided with pressure labelling, respectively has a hole before and after pressure tester, and front hole communicates with syringe cavity, and metapore communicates with air.
During use, when needle point thrusts blood vessel, needle lumen and syringe cavity pressure increase, and blood enters pressure tester by pipeline, and blood promotes the piston compression spring in pressure tester, the piston ceases movement when blood pressure and spring pressure reach balance.The pressure in syringe now can be read by the scale on pressure tester sidewall.Judge that needle point is positioned at intra-arterial or intravenous by pressure size.
Compared with prior art, the beneficial effects of the utility model are that structure is simple, easy to use, can effectively improve deep vein puncture success rate, reduce arterial injury probability and degree, reduce the misery of patient.
Accompanying drawing explanation
Fig. 1 is the structural representation of the deep vein puncture needle embodiment one of this utility model band measuring device.
Fig. 2 is the structural representation of the deep vein puncture needle embodiment two of this utility model band measuring device.
Fig. 3 is the structural representation of measuring device in this utility model.；
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Please first consult Fig. 1, Fig. 1 is the structural representation of the deep vein puncture needle embodiment one of this utility model band measuring device, as shown in the figure, a kind of deep vein puncture needle with pressure tester, comprise piercing needle 1 and syringe 2, this syringe is made up of syringe and piston, forms syringe cavity between piston and syringe, also comprise the pressure tester 3 being arranged on described piston rear end, this pressure tester is communicated with syringe cavity by pipeline.The spring 5 being provided with piston 4 in described pressure tester 3 and being connected with this piston, the sidewall of described pressure tester is also provided with pressure labelling, as shown in Figure 3.
Fig. 2 is the structural representation of the deep vein puncture needle embodiment two of this utility model band measuring device, as shown in the figure, a kind of deep vein puncture needle with pressure tester, comprise piercing needle 1 and syringe 2, also comprise the pressure tester 3 being arranged on described piercing needle and syringe junction, this pressure tester communicates with piercing needle inner chamber.The spring 5 being provided with piston 4 in described pressure tester 3 and being connected with this piston, the sidewall of described pressure tester is also provided with pressure labelling.Pressure tester 3 is cylindrical, transparent, and respectively there is a hole front and back, and front hole communicates with syringe cavity, and metapore communicates with air.
During use, when needle point thrusts blood vessel, needle lumen and syringe cavity pressure increase, and blood enters pressure tester by pipeline, and blood promotes the piston compression spring in pressure tester, the piston ceases movement when blood pressure and spring pressure reach balance.The pressure in syringe now can be read by the scale on pressure tester sidewall.Judge that needle point is positioned at intra-arterial or intravenous by pressure size.
It should be noted last that, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail this utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical scheme of utility model or equivalent replacement, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
