Description

Deep venous puncture device

Technical field

The utility model relates to a kind of deep venous puncture devices.

Background technique

Central venous puncture tube indwelling technology is widely used to clinic, should with the development of medical science and medical technology Technology has been carried out extensively in basic hospital, in blood transfusion, fluid infusion, intravenous nutrition, monitoring center's vein pressure and severe crisis patient Rescue etc. has been widely used, and with constantly improve for the technology, has expanded to haemodialysis, Chemotherapy of Tumor Patients, intracardiac Pace-making, drainage Celom liquid loading etc., current most deep venous puncture uses process generally to sterilize, anaesthetizing, wear It pierces, be inserted into guide wire and set pipe, process is complex, takes a long time, and increases the pain of patient, while also increasing medical care people The labor intensity of member.

Utility model content

The purpose of the utility model is to overcome the above deficiencies in the existing technologies, and provide a kind of structure design conjunction The deep venous puncture device of reason.

The technical scheme in the invention for solving the above technical problem is: a kind of deep venous puncture device, special Sign is: being provided with the cavity for being equipped with built-in pipe including puncturing needle tubing and built-in pipe, the puncture needle, described wears Pricker pipe is divided into syringe needle section, is arranged section and holding tank section, and the syringe needle section is piercing needle, and described is arranged section in hollow Cylindricality, the holding tank section are the receiving groove body that section is semi-circumference annular, built-in pipe be arranged in the cavity of puncture needle and Its outside wall surface is bonded with the inner wall of puncture needle, and the built-in pipe is provided with hollow cavity, one end of the built-in pipe It is provided with the through-hole being connected to its cavity, the other end of built-in pipe is provided with the connection with syringe or injection needle mating connection Head.

Further: one end of the built-in pipe is round end, and the through-hole is opened up in the side of round end.

Further: the connector uses medical female Luer, the maximum outside diameter ruler of the medical female Luer The very little outer diameter less than interior column tube.

Further: the rear end of the puncture needle tubing is fixedly installed hand holding handle, the wall surface setting of the hand holding handle There is anti-slip rubber.

Further: the outer tube wall of the puncture needle tubing is provided with steel seal graduation mark, the outer tube wall of the built-in pipe It is provided with ink printing graduation mark.

The utility model compared with prior art, has the following advantages that and effect: it is reasonable in design, it is disposable import in Pipe is set, without seal wire importing, operating process is relatively simple compared to traditional merging, operates time-consuming end, effectively reduces doctor The working strength of business personnel and the pain of patient.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model embodiment deep venous puncture device.

Fig. 2 is the structural schematic diagram that the utility model embodiment punctures needle tubing.

Fig. 3 is the puncture and intubation schematic diagram of the utility model embodiment deep venous puncture device.

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawing and by embodiment, and following embodiment is pair The explanation of the utility model and the utility model is not limited to following embodiment.

Referring to figures 1-3, a kind of 4 puncture and intubation device of Deep venou of the present embodiment, it is characterised in that: including puncturing needle tubing 1 And built-in pipe 2, the puncture needle are provided with the cavity for being equipped with built-in pipe, the puncture needle tubing 1 divides for syringe needle section 11, it is arranged section 12 and holding tank section 13, the syringe needle section 11 is piercing needle, and the section 12 that is arranged is in hollow cylindrical, The holding tank section 13 is the receiving groove body 14 that section is semi-circumference annular, built-in pipe 2 be arranged in the cavity of puncture needle and Its outside wall surface is bonded with the inner wall of puncture needle, and the built-in pipe 2 is provided with hollow cavity, one end of the built-in pipe It is provided with the through-hole 24 being connected to its cavity, the other end of built-in pipe is provided with the company with syringe 5 or injection needle mating connection Connector 22, one end of the built-in pipe are round end, and the through-hole 24 is opened up in the side of round end, effectively avoids puncture process In built-in lumen generate thrombus blocking, the connector 22 uses medical female Luer, because of the letter of female Luer connection Just property and different medical equipments have extensive compatibility, and can switch note under the premise of not plugging patient fluid infusion's needle tubing Source is penetrated, the maximum outside diameter size of the medical female Luer is less than the outer diameter of interior column tube, convenient for creating being arranged for time syringe needle Section 12 extracts built-in pipe, and the rear end of the puncture needle tubing 1 is fixedly installed hand holding handle 15, and the wall surface of the hand holding handle 15 is set It is equipped with anti-slip rubber, the outer tube wall of the puncture needle tubing is provided with steel seal graduation mark, the outer tube wall setting of the built-in pipe There is ink to print graduation mark, the present embodiment provides carry out the step of Deep venou 4 operates using 4 puncture and intubation device of Deep venou:

1) puncture and prepare: medical care operator carries out the disinfection of the corresponding site of itself and patient, using benefit Cacaine carries out local anaesthesia, and the front end of built-in pipe connects syringe 5.

2) it punctures: checking 4 puncture and intubation device of Deep venou, the through-hole 24 of built-in pipe, which is in, punctures 1 piercing needle position of needle tubing It sets slightly exposing cavity, puncture needle and skin 3 and is pierced into skin 3 to Deep venou 4, when puncture pumpback visible time in 30 ° to 40 ° angles Blood punctures successfully.

3) run-bake-needle fault: built-in pipe is pushed ahead, and hand holds built-in pipe rear end at this time, keeps built-in pipe position motionless, gradually Guidance outward, when being arranged section 12 and syringe needle section 11, successively disengaging punctures skin 3 and is pierced by by the other end of built-in pipe, lays down Syringe 5, so that puncturing needle tubing 1 is detached from built-in pipe.
