Description

Disposable catheter clamp

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to disposable catheter clamp suitable for hemodialysis is effective.

Background

Along with the higher living standard of people, the incidence rate of kidney diseases is increased. At present, there are two dialysis modes for renal failure patients, one is hemodialysis treatment, and the other is peritoneal dialysis treatment. However, in clinical practice, hemodialysis is the most effective method for treating acute and chronic renal failure and acute drug intoxication. Before the autologous arteriovenous internal fistula is mature, a dialysis catheter is mostly adopted as a dialysis passage of a patient, and the vascular dialysis passage is just like a life line of the patient and has self-evident importance to the patient. The semi-permanent catheter is preferably placed into a patient with a long age and poor vascular condition clinically. For such patients who will be hemodialysis for about 3 times a week, the tube is easily damaged and the tube clamp is easily broken due to repeated use of the tube, so that the patients are exposed to risks of heavy bleeding, infection, tube replacement, dialysis interruption and the like, the pain of the patients is increased, the economic burden of the patients is increased, and the medical consumption is increased.

Consequently, to the easy fracture of pipe clamp and the difficult problem of replacement on the pipe for hemodialysis among the prior art, the utility model discloses plan to design a disposable pipe clamp, can install on the pipe when supporting pipe clamp fracture on the hemodialysis pipe, realize the function of pipe clamp to protection pipe that can be better.

SUMMERY OF THE UTILITY MODEL

To the problem that prior art exists, the utility model discloses a solve the technical scheme that the problem that exists adopts among the prior art as follows:

a disposable catheter clamp, comprising: including the two half structures that set up relatively, every half structure all includes the arc frame, connects two pipe splint inboard at the frame, is equipped with the opening on the frame, and open position is equipped with wedge locked groove and fore shaft, on the two half structure opposite faces, be equipped with a plurality of draw-in grooves of matched with and checkpost, specifically be half structure and seted up a plurality of draw-in grooves, corresponding checkpost is seted up to second half structure.

The catheter clip is made of plastic materials with certain toughness.

The draw-in groove sets up the left and right sides medial surface at two arc frames with the checkpost to and on the pipe splint inboard facing inside, the frame thickness that is located the left and right sides is greater than the frame thickness of downside, makes the complete pipe clamp upper and lower position fretwork of piecing together, and the pipe can pass the pipe clamp smoothly, and the pipe splint parallel arrangement after the chucking, the clearance slightly is less than pipe compression thickness between the two, makes the pipe clamp press from both sides tightly the back, and two pipe splint can tightly clip the pipe.

The use method of the disposable catheter clamp comprises the following steps: place the two half structures of pipe clamp respectively in the pipe both sides, press two half structures relatively, make in one of them half checkpost card advances the draw-in groove of second half structure to become a complete pipe clamp, the pipe is located between two pipe splint this moment, then press the fore shaft and make the fore shaft card in the locked groove, thereby make two pipe splint merge the clamp closure pipe, realize the function that the pipe pressed from both sides.

The utility model has the advantages of as follows:

the disposable conduit clamp of the utility model improves the linear conduit clamping structure in the middle of the existing fixed conduit clamp into a plate-shaped clamping structure, increases the contact area between the conduit clamp and the conduit, reduces the abrasion caused by the clamping of the conduit in multiple use, and prolongs the service life of the conduit; through the utility model discloses disposable pipe clamp, original pipe clamp fracture is bad to be replaced when falling, has avoided among the prior art when falling in the face of the pipe clamp is bad, often needs take out the hemodialysis pipe from the patient is internal, carries out whole replacements, the misery that brings for the patient to and the waste of medical resource.

fig. 2 is an inside view of the other half of the catheter clip of the present invention;

FIG. 3 is a schematic view of a prior art hemodialysis catheter;

wherein: 1-clamping groove, 2-clamp, 3-catheter clamping plate, 4-locking groove, 5-locking notch, 6-venous tube, 7-arterial tube and 8-intracorporeal tube.

Detailed Description

The technical solution of the present invention is further described in detail by the following embodiments with reference to the accompanying drawings, as shown in fig. 1-2, a disposable catheter clamp is characterized in that: including the two half structures that set up relatively, every half structure all includes the arc frame, connects two pipe splint inboard at the frame, is equipped with the opening on the frame, and open position is equipped with wedge locked groove 4 and fore shaft 5, on the two half structure opposite faces, be equipped with a plurality of draw-in grooves of matched with and checkpost, specifically for half structure has seted up a plurality of draw-in grooves 1, and corresponding checkpost 2 has been seted up to second half structure.

The conduit clamp is made of plastic materials with certain toughness.

Draw-in groove and checkpost setting are at the left and right sides medial surface of two arc frames to and on the pipe splint inboard inside surface, the frame thickness that is located the left and right sides is greater than the frame thickness of downside, make the complete pipe clamp upper and lower position fretwork of piecing together, the pipe can pass the pipe clamp smoothly, pipe splint parallel arrangement after the chucking, the clearance slightly is less than pipe compression thickness between the two, make the pipe clamp press from both sides tight back, two pipe splint can tightly clip the pipe.

The use method of the disposable catheter clamp comprises the following steps: place the two half structures of pipe clamp respectively in the pipe both sides, press two half structures relatively, make in one of them half checkpost 2 card advances the draw-in groove 1 of second half structure to become a complete pipe clamp, the pipe lies in between two pipe splint 3 this moment, then presses fore shaft 5 and makes the fore shaft card in locked groove 4, thereby makes two pipe splint 3 merge the clamp closure pipe, realizes the function that the pipe pressed from both sides.

Fig. 3 is a schematic view showing a structure of a catheter for hemodialysis in the prior art, wherein an internal tube 8 is inserted into a patient, and catheter clamps are arranged on a venous tube 6 and an arterial tube 7 for controlling the on-off of a liquid passage in the catheter; through the utility model discloses disposable pipe clamp, original pipe clamp fracture is bad to be replaced when falling, has avoided among the prior art when falling in the face of the pipe clamp is bad, often needs take out the hemodialysis pipe from the patient is internal, carries out whole replacements, the misery that brings for the patient to and the waste of medical resource.

The scope of the present invention is not limited to the above-described embodiments, and it is apparent that those skilled in the art can make various modifications and variations to the present invention without departing from the scope and spirit of the present invention. It is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
