Abstract
The utility model discloses a peritonaeum dialysis puncture needle, which is characterized in that one end of a handle is fixed to one end of a puncture needle core. The other end of the puncture needle core forms a cone-shaped body. A section of the puncture needle core near the handle is provided with a screw hole, and the outside of the puncture needle core is in sleeve joint with a jacket tube. The section of the jacket tube is provided with a bolt hole corresponding to the screw hole of the puncture needle core. The jacket tube is fixed to the puncture needle core into integration through screw bolts. The end of the jacket tube is an adducent mouth, which is in sleeve joint with the cone-shaped body of the puncture needle core. The utility model has the advantages of simple structure, easy production, simple operation, small incision, hard damage on organs and convenient popularization in hospitals with different levels. Another dialysis tube can be arranged newly along an existing puncture point when a dialysis tube is clogged.
Description
This utility model relates to a kind of medium is imported in the body or in body and takes out the medical apparatus and instruments that medium is used, particularly a kind of peritoneal dialysis puncture needle.
Peritoneal dialysis is one of method of treatment acute or chronic renal failure determined curative effect, and peritoneal dialysis art for a long time adopts modus operandi to put pipe, and how 3cm place open abdomen is inserted bladder rectum crypts with ring clamp with peritoneal dialysis catheter until peritoneum under umbilicus.Carry out peritoneal dialysis in this way and have following defective, the one, the modus operandi complicated operation, generally need the urological surgeon to implement, the 2nd, operating time is long, and long incision is implemented this operation and often needed one hour, there is 5cm above (especially fat person) in otch more, wound is big, and wound healing is slow, and complication is many (as hemorrhage, infect, accidentally injure internal organs, fistula of abdominal wall, intestinal adhesion etc.), (protein content height in the HFRS peritoneum peritoneal effluent after the pipe choking of peritoneal dialysis simultaneously, easily block, if have hemorrhage, easier obstruction), wash obstructedly, must put pipe again, if put pipe again from former otch, need open the abdominal cavity once again, not only make the tissue of wound increase the weight of damage, and airtight poor around the saturating folding pipe, and dialysis solution has from managing the possibility of exosmosing in week, dialysis-effect but also easily secondary infection had not only been influenced, again put pipe if change the position, then increase patient tissue wound and misery, dialysis solution can exosmose from former otch.
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of easy and simple to handle, and otch is little, and easy damaged internal organs not can be put the peritoneal dialysis puncture needle of pipe again along former point of puncture after Dialysis tubing blocks.
The purpose of this utility model realizes by following technical proposals:
The design leader is affixed with the puncture nook closing member, and puncture nook closing member peripheral hardware has a sleeve pipe, and the nearly handle of puncture nook closing member position is provided with a screw, is provided with a bolt hole with the sleeve pipe of nook closing member screw corresponding position, and sleeve pipe is connected by bolt with the nook closing member that punctures.
To puncture earlier during use nook closing member and sleeve pipe socket, and make the two binding in aggregates with bolt, again with the point of puncture incision of skin 0.5cm otch of local anesthesia, separate subcutaneous tissue with vascular forceps, puncture needle is vertically thrust the abdominal cavity along otch, again stainless steel silk is inserted in the peritoneal dialysis catheter, unclamp bolt, extract nook closing member, the peritoneal dialysis catheter of strip steel silk is inserted bladder rectum crypts through sleeve pipe, take out sleeve pipe after pulling out steel wire, fixedly peritoneal dialysis catheter is connected the peritoneal dialysis solution carrier pipe and can be dialysed.In the time of need putting pipe again after Dialysis tubing blocks, take out and blocked Dialysis tubing, insert the peritoneal dialysis puncture needle from former otch again, reach nook closing member, and in sleeve pipe, the Dialysis tubing of changing is inserted bladder rectum crypts, proceed dialysis.
From above-mentioned situation as can be known, the purpose of this utility model can realize, because its otch is less, the peritoneal dialysis puncture needle directly passes stomach wall and peritoneum, and by extracting nook closing member, stay sleeve pipe and make passage, make Dialysis tubing arrive bladder rectum crypts by stomach wall more smoothly, in case Dialysis tubing blocks, can take out very easily and insert again, insert the week sealing of back Dialysis tubing more better, the ne-leakage phenomenon is used through clinical ten multidigit patients, its safety simple to operate, just can finish in 10-15 minute and put pipe, otch is 0.5cm only, does not see that an example has complication.This peritoneal dialysis puncture needle is simple in structure, easy to manufacture, and its using method of clinician's easy to perform is suitable for promoting in hospitals at different levels.
Accompanying drawing and drawing are described as follows:
Accompanying drawing is this utility model configuration diagram.
In conjunction with the embodiments this utility model is further described with reference to the accompanying drawings below:
As shown in the figure, design one with handles 1 peritoneal dialysis puncture nook closing member 3, handle 1 is designed to one with nook closing member 3 or the two row is affixed, present embodiment is selected the two built-in structure for use, nook closing member is garden cylindricality or triangle, present embodiment is selected the garden cylindricality for use, and length is good with 6-8cm, and present embodiment is selected 8cm for use, the tapered body in its end, bullet length is good with 0.5-1cm, and present embodiment is selected 0.8cm for use, and the nearly handle end of nook closing member is provided with a cylindricality screw 2, as shown in the figure, design a hollow sleeve 5, casing inner diameter adapts with puncture nook closing member shape size, so that the two can socket not stay the gap, sleeve pipe one end is provided with outside one collar head 4 that expands, in case sleeve pipe is strayed into the abdominal cavity, casing length is decided with nook closing member length, makes big of the bullet of nook closing member exposed.The telescopic other end is interior closing in, so that fit tightly with the bullet of nook closing member 3, the nearly collar head of sleeve pipe position promptly is provided with a bolt hole with the corresponding position of the screw on the nook closing member, so that with bolt nook closing member and sleeve pipe are fixed as one.
Claims (2)
1, a kind of peritoneal dialysis puncture needle, form by handle, nook closing member and sleeve pipe, it is characterized in that handle (1) one end is affixed with puncture nook closing member (3) one ends, the puncture needle other end is a bullet, the nearly handle of puncture nook closing member position is provided with a screw (2), and puncture nook closing member overcoat connects a sleeve pipe (5), and the screw corresponding position on sleeve pipe (5) and the nook closing member is provided with bolt hole, sleeve pipe and nook closing member are connected into one by bolt, and sleeve pipe and nook closing member cone socket end are to close up in one.
