Description
Technical Field
The utility model belongs to the technical field of medical instrument, especially, relate to a take press device's arteriopuncture to keep somewhere needle.
Background
Currently, the current state of the art commonly used in the industry is such that: the arteriopuncture catheterization can be widely applied to clinic because the dynamic blood pressure of a patient can be rapidly and continuously monitored and the blood sample of the patient can be conveniently collected. The currently clinically used arterial puncture needle generally consists of an inner tube (steel needle core) and an outer tube (remaining needle), wherein after the steel needle core is successfully punctured and the remaining needle is placed into an artery, the steel needle core is withdrawn, and then the remaining needle is connected with an arterial sensor. Before withdrawing the steel needle core, the approximate position of the front end of the indwelling needle in the artery needs to be estimated in advance, effective compression is performed to prevent blood from overflowing from the indwelling needle, and the sensor is connected quickly. In the current practical clinical operation process, a great amount of blood often gushes out from the artery indwelling needle due to inaccurate estimated position, inadequate compression position or small compression force. When the front end of the indwelling needle is compressed, a patient often generates certain distending pain, the quick connection sensor has certain technical requirements on an operator while accurately compressing an artery, and the overflow of arterial blood of the patient causes certain blood loss, causes pollution to the skin of the patient and surrounding environments such as a hand pad and a hand frame, and has the risk of cross infection.
In summary, the problems of the prior art are as follows:
(1) the traditional process that the artery indwelling needle is connected with the sensor needs to compress the artery of the patient to cause pain, and the technical requirement on an operator is high.
(2) The overflow of blood in the process of connecting the traditional arterial indwelling needle with the sensor causes the blood loss of a patient, the blood pollution to the surrounding environment and the risk of cross infection.
SUMMERY OF THE UTILITY MODEL
To the problems existing in the prior art, the utility model provides an arterial puncture indwelling needle with a pressing device.
The utility model is realized in such a way that the artery puncture indwelling needle with the pressing device comprises a steel needle core inner tube and an artery indwelling needle tube sleeved outside the steel needle core;
the steel needle core inner tube consists of an inner tube needle tube part and an inner tube needle seat part, and the inner tube needle tube part is inserted in the inner tube needle seat part;
the artery indwelling needle tube comprises an indwelling needle tube and an indwelling needle seat, and the indwelling needle tube is inserted into the indwelling needle seat.
Furthermore, the indwelling needle seat is cylindrical, and the diameter of the indwelling needle seat is slightly larger than that of the inner tube needle seat to be intussuscepted.
Furthermore, the outer side of the top end of the indwelling needle seat is provided with threads, and an artery sensor pipeline is sleeved on the indwelling needle seat.
Furthermore, notches are formed in two sides of the middle part of the indwelling needle seat, rubber pipes are installed in the notches, and the rubber pipes are connected with the indwelling needle seat through connecting parts;
and a pressing strip block is arranged outside the notch and is fixed outside the notch through a connecting belt.
In summary, the advantages and positive effects of the invention are: the artery puncture indwelling needle with the pressing device is provided with a notch in the middle of the casing of the artery indwelling needle, so that the rubber tube is exposed, and meanwhile, certain hardness is kept, and the operation is convenient. The rubber tube is arranged in the gap, and the self-heating shape can be kept when the rubber tube is not stressed. The outside strip piece that presses of breach can seal the rubber tube when receiving external force extrusion. The pressing bar blocks are fixed at the two ends of the notch, so that extra workload is not increased; the design is simple, and the practicality is strong.

Detailed Description
In order to further understand the contents, features and effects of the present invention, the following embodiments are illustrated and described in detail with reference to the accompanying drawings.
Aiming at the problems in the prior art, the invention provides an arterial puncture indwelling needle with a pressing device, and the invention is described in detail with reference to the attached drawings 1 and 2.
The artery puncture indwelling needle with the pressing device adopts an artery puncture needle with a one-way valve, and comprises a steel needle core inner tube 1 and an artery indwelling needle tube sleeved outside the steel needle core. The inner tube 1 of the steel needle core consists of an inner tube needle tube part 3 and an inner tube needle seat part 4. The artery indwelling needle tube 2 comprises an indwelling needle tube 5 and an indwelling needle seat 6, wherein the indwelling needle seat 6 is cylindrical, and the diameter of the indwelling needle seat is slightly larger than that of the inner tube needle seat 4 for intussusception. Be equipped with screw thread 7 in the outside of keeping somewhere 6 top ends of needle file for link up with the screw thread of arterial sensor pipeline, keep somewhere 6 mid portion both sides of needle file and design jaggedly 10, its inside rubber tube 8 that is, rubber tube 8 is connected with keeping somewhere needle file 6 through connecting portion 9. A pressing strip 11 is arranged outside the notch 10 and fixed outside the notch through a connecting belt 12.
When the artery puncture needle is used for artery puncture and tube placement, an operator holds the inner tube needle seat part 4 with one hand to perform artery puncture, after the inner tube needle tube 3 of the steel needle core punctures the artery successfully and returns blood, holds the outer tube indwelling needle seat 6 with the other hand to place the outer tube indwelling needle tube part 5 into the artery, presses the pressing strip block 11 to seal the rubber tube 8, and finally completely withdraws the inner tube needle core part 3 from the outer tube indwelling needle tube part 6 to complete artery tube placement. At the moment, the connecting pipe of the artery sensor and the thread 7 at the outer side of the top end of the indwelling needle seat 6 can be rotationally connected, and after the success, the pressing strip block is loosened, and the rubber pipe 8 is re-stretched due to natural elasticity.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all the modifications and equivalents of the technical spirit of the present invention to any simple modifications of the above embodiments are within the scope of the technical solution of the present invention.
