Description

A kind of semipermanent hemodialysis catheter

Technical field

The utility model belongs to medical field, and in particular to a kind of semipermanent hemodialysis catheter.

Background technique

The common treatment of haemodialysis replaces the internal metabolism of kidney removing useless in the patient of acute or chronic renal failure, with machine Object maintains electrolyte and acid-base balance, while removing internal excess moisture, and by defeated time patient's body of purified blood, and The bridge that hemodialysis catheter is connect as machine end with human body, it is most important in dialysis treatment, therefore, either set pipe also It is that tube drawing requires veteran medical staff and could go up hand operation, also, general hemodialysis catheter is in catheterization procedure Need to undergo local anaesthesia, puncture vein haemospasia, wear silk, sheath expands skin, beat hypodermic tunnel, be intubated, reeling off raw silk from cocoons, suture needle, washes pipe, Whole process lasts length, and wound area is big, and tube drawing bleeding is big, extremely painful for the patient.

Summary of the invention

In view of the deficienciess of the prior art, the utility model provides a kind of blood convenient for being intubated, mitigating patient suffering Dialysis catheter.

The utility model is achieved through the following technical solutions:

A kind of semipermanent hemodialysis catheter, including supervisor, bloodletting tube, blood return tube, attachment base and draw silk, in the supervisor It is divided into the identical upper tube half of flux and lower tube half by diaphragm, is embedded with a pair of of silk between the diaphragm two sides and supervisor's inner wall Line, the wire length is identical as the diaphragm length, is connected to the bloodletting tube by the attachment base on the left of the upper tube half, Directing tube and the blood return tube, the directing tube and the lower tube half are respectively communicated with by the attachment base on the left of the lower tube half It is interior through have it is described draw silk, described to draw a right end rounding, left end is connected with pull ring, on the attachment base on the outside of the directing tube It hangs and is connected to pipe close, the pipe close two sides are provided with bayonet lock, and front and back is symmetrically arranged with fixture block, the bayonet lock and institute on the attachment base State fixture block cooperation.

The diaphragm and the supervisor are an entirety.

The silk thread preferably uses titanium silk.

It is provided with red pipe clamp on the bloodletting tube, blue pipe clamp is provided in the blood return tube.

The bloodletting tube and the blood return tube left end are provided with machine connecting pin.

Compared with prior art, the utility model has the beneficial effects that the utility model draws silk enhancing master by preset The intensity of pipe merging supervisor, shortening indwelling catheter time can reduce wound, reduce patient's pain in the case where expanding skin without using sheath Hardship, and infection risk is reduced to a certain extent；Drawing silk and can be extracted out with pull ring by directing tube after the completion of pipe is set, directing tube is blocked Plug, and hold-open catch can restore the unobstructed suppleness being responsible for of blood return tube, reduce medical staff's working strength；In addition, It is embedded with titanium silk between diaphragm and supervisor's wall, on the one hand can prevent from drawing in a withdrawal process, is responsible for contraction distortion, on the other hand, is prevented It is only responsible for excessive torsional deflection, improves reliability and service life.

Specific embodiment

As in Figure of description Fig. 1 to a kind of semipermanent hemodialysis catheter shown in fig. 6, including supervisor 1, bloodletting tube 2, Blood return tube 3, attachment base 4 and draw silk 5, is divided in supervisor 1 by diaphragm 7 for the identical upper tube half 8 of flux and lower tube half 9,7 liang of diaphragm It is embedded with a pair of of silk thread 10 between 1 inner wall of side and supervisor, 10 length of silk thread is identical as 7 length of diaphragm, passes through connection on the left of upper tube half 8 Seat 4 is connected to bloodletting tube 2, passes through attachment base 4 on the left of lower tube half 9 and is respectively communicated with directing tube 11 and blood return tube 3, directing tube 11 and lower half Run through to have in pipe 9 and draw silk 5, draw the intensity of the enhancing of silk 5 supervisor 1, supervisor 1 can be placed in the case where expanding skin without using sheath, on 8 end of semicanal is the side opening of dedolation, and common seal wire can be introduced by blood return tube 3.

Draw 5 right end rounding of silk, avoid mechanical damage, left end is connected with pull ring 12, and the attachment base 4 in 11 outside of directing tube is hung oneself It is connected to directing tube plug 13,13 two sides of directing tube plug are provided with bayonet lock 14, and front and back is symmetrically arranged with fixture block 6, bayonet lock 14 on attachment base 4 Cooperate with fixture block 6, sets drawing silk 5 and can be extracted out with pull ring 12 by directing tube 11 after the completion of pipe, block directing tube plug 13, and fixing card Pin 14 can restore the suppleness of the unobstructed of blood return tube 3 and supervisor 1, carry out dialysis treatment.

Diaphragm 7 and supervisor 1 are an entirety.

Silk thread 10 preferably uses titanium silk, and corrosion-resistant, mechanical performance is superior, elasticity modulus is close to natural bone, with human contact It is not likely to produce repulsion and allergic reaction, on the one hand can prevent from drawing in 5 withdrawal process of silk, is responsible for 1 contraction distortion, on the other hand, is prevented It is only responsible for 1 excessive torsional deflection, improves reliability and service life.

It is provided with red pipe clamp 15 on bloodletting tube 2, blue pipe clamp 16 is provided in blood return tube 3, is not carrying out dialysis treatment In the case where closing pipe line, prevent blood backflow.
