Description
Technical Field
The utility model relates to the technical field of medical instruments, in particular to an improved tunnel needle for peritoneal dialysis intubation.
Background
The medical apparatus refers to instruments, equipment, appliances, in-vitro diagnostic reagents and calibrators, materials and other similar or related articles which are directly or indirectly used for the human body, and comprises required computer software for diagnosing, preventing, monitoring, treating or relieving diseases; diagnosis, monitoring, treatment, mitigation, or functional compensation of injury; examination, replacement, regulation or support of a physiological structure or physiological process; support or maintenance of life; controlling pregnancy; the examination of a sample from a human body provides information for medical or diagnostic purposes, peritoneal dialysis is an important renal replacement therapy for treating end-stage renal disease, peritoneal dialysis catheterization is a prerequisite and key for peritoneal dialysis, and although peritoneal dialysis catheterization is well-established, tunnel needles in the operation still have the following problems in the application process, resulting in prolonged operation time and increased damage and complications in the operation.
(1) In the using process of the traditional tunnel needle, a catheter connected with the tail part of the traditional tunnel needle is easy to fall off under the blocking of subcutaneous fat and other tissues;
(2) because there is kafu (white dacron cover) structure in the peritoneal dialysis pipe, the expansion of traditional tunnel needle is not enough, leads to the pipe often to be difficult to draw out subcutaneously, needs extra vascular pincers expansion tunnel, leads to unnecessary damage.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
Aiming at the defects of the prior art, the utility model provides an improved tunnel needle for peritoneal dialysis intubation, which solves the problems in the prior art.
(II) technical scheme
In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a peritoneal dialysis puts effective improvement type tunnel needle, includes the tunnel needle body, the lateral wall bottom threaded connection of tunnel needle body has the tail cap, the tail cap is both ends opening and hollow structure, the bottom of tunnel needle body is located the inside of tail cap is fixed with the connector.
Preferably, the tunnel needle body includes head section, middle section and tail section, the head section the middle section with tail section integrated into one piece has, the left end of head section is pinpoint column structure, the middle section is crooked column structure, and the curvature is 100.
Preferably, the connector is that five annular grooves are formed in the outer side wall from top to bottom in an integrated mode, and the distance between two adjacent annular grooves is 2 mm.
Preferably, the tunnel needle body and the tail cap are both made of metal materials.
(III) advantageous effects

Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic view of the internal structure of the present invention.
In the figure: 1. a tunnel needle body; 101. a head section; 102. a middle section; 103. a tail section; 2. a tail cap; 3. a connecting head.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1-2, the present invention provides a technical solution: the utility model provides a peritoneal dialysis puts effective improvement type tunnel needle, including tunnel needle body 1, tunnel needle body 1's lateral wall bottom threaded connection has tail cap 2, tail cap 2 is both ends opening and hollow structure, tunnel needle body 1's bottom is located the inside of tail cap 2 and is fixed with connector 3, before using, at first with tail cap 2 spiro union on tunnel needle body 1, then with pipe connection on connector 3, in the in-process of using, when tunnel needle passes subcutaneous, tail cap 2 can protect the pipe, avoid the pipe under the blockking of subcutaneous fat and other tissues, the pipe takes place the condition that drops in subcutaneous easily, and because the diameter of tail cap 2 is greater than tunnel needle body 1's diameter, it can suitable increase the expanded range, thereby can make the smooth passing through of peritoneal dialysis card husband structure.
Further, tunnel needle body 1 includes head section 101, middle section 102 and tail section 103, and head section 101, middle section 102 and tail section 103 integrated into one piece have, and the left end of head section 101 is pinpoint column structure, and middle section 102 is crooked column structure, and the curvature is 100, can make things convenient for tunnel needle body 1 to use more.
Further, connector 3 has five annular grooves for lateral wall from the top down integrated into one piece, and the interval between two adjacent annular grooves is 2mm, avoids the condition that the pipe that connector 3 is connected takes place to drop from connector 3 easily.
Further, tunnel needle body 1 and tail cap 2 are the metal material, make whole tunnel needle can tolerate high temperature high pressure disinfection to can used repeatedly.
In conclusion, the working process of the utility model is as follows: before using, at first with tail cap 2 spiro union on tunnel needle body 1, then connect the pipe on connector 3, in the in-process of using, when the tunnel needle passes subcutaneous, tail cap 2 can protect the pipe, avoids the pipe to be in subcutaneous fat and other tissue's the circumstances that blocks, the pipe easily takes place to drop under the skin to because the diameter of tail cap 2 is greater than tunnel needle body 1's diameter, it can be appropriate increase the range of expansion, thereby can make the smooth passing through of peritoneal dialysis catheter cuff structure.
