Abstract
The utility model relates to the technical field of medical instruments, in particular to a single-wing arterial indwelling needle. The single-wing arterial indwelling needle is composed of a tubular needle, an indwelling catheter, a pressure measuring tube, a three-way valve and an indwelling needle protection sleeve. A needle point of the tubular needle penetrates through a rubber check valve to be arranged in the indwelling catheter, a needle base is inserted at the tail end of an indwelling catheter base to be fixed, the needle point of the tubular needle is exposed out of the indwelling catheter, and the needle point of the tubular needle and the indwelling catheter are sleeved with the indwelling needle protection sleeve. According to the single-wing arterial indwelling needle, a single-wing handle can be easily held during puncturing, and patient blood losing and operator pollution can be avoided through the rubber check valve. The pressure measuring tube is connected, and blood returning can be conveniently observed during puncturing to judge whether puncturing is successful or not. A 30-degree included angle is formed between the indwelling catheter base and a side tube, the fixing area is increased, and fixing after tube placing is facilitated.
Description
Technical field
This utility model relates to technical field of medical instruments, especially a kind of single-blade needle of retaining on artery.
Background technology
Cavity in Critical Patients, in order to carry out direct arteriotony monitoring and to gather the chemical examination of arterial blood row blood gas analysis, needs indwelling needle of retaining on artery.The needle of retaining on artery using clinically, be straight needle of retaining on artery iv cannule as bright in shellfish, BD needle of retaining on artery, there is following shortcoming in straight needle of retaining on artery: without being difficult for observing blood back in gripping handle operation inconvenience, puncture, has reduced puncture success rate, pulled out nook closing member artery blood and gush out and cause patient to lose blood and operator pollutes, is difficult for fixing.Zhang Xiuxia uses the capable arterial intubation of Y shape venous detaining needle in the capable Radial Artery Cannulation > of < < skilful use Y shape venous detaining needle >, but venous detaining needle because of conduit material hardness inadequate, accurately Monitoring of blood pressure, only can be used for gathering arterial blood specimen.
Summary of the invention
In order to overcome the above-mentioned deficiency of existing needle of retaining on artery, this utility model provides a kind of single-blade needle of retaining on artery.
This utility model solves the technical scheme that its technical problem adopts: described single-blade needle of retaining on artery is comprised of bobbin 6, inlying catheter 4, pressure-measuring pipe 2, three-way valve 1 and indwelling needle-protecting sleeve 5; Wherein:
The end of bobbin 6 is fixed with needle stand 9, and bobbin 6 is hollow pipe, and needle stand 9 is made as one with single-blade handle 8, when single-blade handle 8 is beneficial to puncture, grips, and meets China nursing staff and puts the puncture custom while managing, and improves puncture success rate;
One end of inlying catheter 4 is that inlying catheter seat 10, inlying catheter seat 10 have side pipe 3; At inlying catheter seat 10 inner chambers, between side pipe 11 and inlying catheter seat 10 ends, be provided with rubber check (non-return) valve 7, punctured and pulled out after bobbin 6, can effectively avoid blood to gush out, avoided patient to lose blood and operator's pollution; Inlying catheter 4 is transparent hollow tube with inlying catheter seat 10;
One end of pressure-measuring pipe 2 is connected with side pipe 3, other end connecting tee valve 1; Connect pressure-measuring pipe 2, while being convenient to puncture, observe blood back and puncture successfully judging whether.
Bobbin 6 needle points are placed in inlying catheter 4 through rubber check (non-return) valve 7, and needle stand 9 is inserted in inlying catheter seat 10 ends and fixes, and bobbin 6 needle points are exposed outside inlying catheter 4, and indwelling needle-protecting sleeve 5 is enclosed within outside bobbin 6 needle points and inlying catheter 4.
11 one-tenth 30 degree angles of inlying catheter seat 10 and side pipe.
Pressure-measuring pipe 2 is made by medical polyvinyl material, and hardness is high, and pressure measurement is accurate.
The material of bobbin 6 is medical stainless steel.The material of inlying catheter 4 is medical macromolecular materials.
The beneficial effects of the utility model are: when single-blade handle is beneficial to puncture, grip, rubber check (non-return) valve can avoid patient to lose blood and operator pollutes.Connect pressure-measuring pipe, while being convenient to puncture, observe blood back and puncture successfully judging whether.Inlying catheter seat and side pipe form 30 degree angles, have strengthened fixed-area, are beneficial to put to manage rear fixing.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is this utility model structural representation.
1. three-way valve in figure, 2. pressure-measuring pipe, 3. side pipe, 4. inlying catheter, 5. indwelling needle-protecting sleeve, 6. bobbin, 7. rubber check (non-return) valve, 8. single-blade handle, 9. needle stand, 10. inlying catheter seat.
The specific embodiment
The end of bobbin 6 is fixed with needle stand 9, and bobbin 6 is hollow pipe, and needle stand 9 is made as one with single-blade handle 8.One end of inlying catheter 4 is that inlying catheter seat 10, inlying catheter seat 10 have side pipe 3; At inlying catheter seat 10 inner chambers, between side pipe 11 and inlying catheter seat 10 ends, be provided with rubber check (non-return) valve 7; Inlying catheter 4 is transparent hollow tube with inlying catheter seat 10.One end of pressure-measuring pipe 2 is connected with side pipe 3, other end connecting tee valve 1.Bobbin 6 needle points are placed in inlying catheter 4 through rubber check (non-return) valve 7, and needle stand 9 is inserted in inlying catheter seat 10 ends and fixes, and bobbin 6 needle points are exposed outside inlying catheter 4, and indwelling needle-protecting sleeve 5 is enclosed within outside bobbin 6 needle points and inlying catheter 4.11 one-tenth 30 degree angles of inlying catheter seat 10 and side pipe.Pressure-measuring pipe 2 is made by medical polyvinyl material, and hardness is high, and pressure measurement is accurate.The material of bobbin 6 is medical stainless steel.The material of inlying catheter 4 is medical macromolecular materials.
