Description
Technical field
This utility model relates to medical instruments field, is specifically related to a kind of hemodialysis remaining needle.
Background technology
Uremic patient often needs to carry out hemodialysis to sustain life for a long time.
The hemodialysis remaining needle of current domestic use, have the following disadvantages: its extension tube part is too short, it is inconvenient when the front vascular forceps of upper power traction blood clamps this part, and vascular forceps has certain weight metal object, easy tractive dialysis venous detaining needle, makes pin be shifted, even deviates from, more easily crush patient, increase the misery of patient.Some remaining needle employs liquid stopping clamp, but liquid stopping clamp is thinner, flexible during use, and easily skids, and makes troubles to operation.
Utility model content
The purpose of this utility model is to provide a kind of hemodialysis remaining needle, to solve the deficiencies in the prior art.
In order to achieve the above object; the technical solution of the utility model is: a kind of hemodialysis remaining needle, comprises body, catheter block, slide fastener, extension tube, joint of extending, puncture needle tubing, injection cap, Paracentesis needle holder, exhaust joint and the sheath for the protection of body.Body rear end is connected with catheter block front end, is provided with extension tube between catheter block rear end and joint of extending front end; Slide fastener is arranged in extension tube, is provided with a drops through hole below slide fastener, and above through hole and oblique below is connected to a chute, and tiltedly the chute of below extends to slide fastener wall, and slide fastener upper end is provided with reinforcement; Puncture needle tubing is arranged between joint of extending rear end and injection cap front end, and injection cap rear end is connected with Paracentesis needle holder, and exhaust joint is connected to Paracentesis needle holder rear end.
The width of slide fastener upper hopper chute is less than the width of through hole.
beneficial effect
This utility model structure is simple, easy to use.Extension tube adds a slide fastener, extension tube can be clamped more easily, eliminate the inconvenience and potential danger that use vascular forceps to bring, more convenient, safer; And slide fastener is provided with reinforcement, when making slip slide fastener, not easily distortion, but also play anti-skidding effect, convenient operation.

Detailed description of the invention
Below in conjunction with accompanying drawing 1-3, detailed description of the invention of the present utility model is described in detail.
A kind of hemodialysis remaining needle, comprises body, catheter block, slide fastener, extension tube, joint of extending, puncture needle tubing, injection cap, Paracentesis needle holder, exhaust joint and the sheath for the protection of body.Body rear end is connected with catheter block front end, is provided with extension tube between catheter block rear end and joint of extending front end; Slide fastener is arranged in extension tube, is provided with a drops through hole below slide fastener, and above through hole and oblique below is connected to a chute, and tiltedly the chute of below extends to slide fastener wall, slide fastener upper end is provided with reinforcement, when making slip slide fastener, not easily distortion, but also play anti-skidding effect, convenient operation; Puncture needle tubing is arranged between joint of extending rear end and injection cap front end, and injection cap rear end is connected with Paracentesis needle holder, and exhaust joint is connected to Paracentesis needle holder rear end.The width of slide fastener upper hopper chute is less than the width of through hole.
During use, first puncture, punctured and carried out rollback puncture needle, when needle point rollback is to slide fastener place, slip slide fastener makes extension tube enter chute, and clamping extension tube, detaches puncture needle subsequently, connect corresponding dialysis pipeline, slip slide fastener, extension tube is slipped in through hole and carries out hemodialysis.
Claims (2)
1. a hemodialysis remaining needle, comprise body, catheter block, slide fastener, extension tube, joint of extending, puncture needle tubing, injection cap, Paracentesis needle holder, exhaust joint and the sheath for the protection of body, it is characterized in that: body rear end is connected with catheter block front end, between catheter block rear end and joint of extending front end, be provided with extension tube; Slide fastener is arranged in extension tube, is provided with a drops through hole below slide fastener, and above through hole and oblique below is connected to a chute, and tiltedly the chute of below extends to slide fastener wall, and slide fastener upper end is provided with reinforcement; Puncture needle tubing is arranged between joint of extending rear end and injection cap front end, and injection cap rear end is connected with Paracentesis needle holder, and exhaust joint is connected to Paracentesis needle holder rear end.
2. a kind of hemodialysis remaining needle according to claim 1, is characterized in that: the width of slide fastener upper hopper chute is less than the width of through hole.
