Abstract
The utility model discloses a batching plug of a vein indwelling needle, a slash is backwardly formed on the front end surface of the batching plug in the axial direction, the maximum width of the slash is less than the diameter of the batching plug, and the final end of the slash is close to the rear end surface of the batching plug. The utility model has the advantages that the structure is simple, the use is convenient, the sealing performance is good, and the batching plug can effectively avoid the infiltration flow of the blood.
Description
Technical field
This utility model relates to a kind of venous detaining needle batching pig.
Background technology
Venous detaining needle is as the regeneration product of scalp draw point, be widely used in clinical, its advantage more and more by the nursing staff cognition.
The advantage of venous detaining needle has: (1) venous indwelling needle cannula is made by advanced person's biomaterial Vialon, and sleeve pipe softness, toughness be big, be difficult for the injured blood vessel wall and cause and exosmose that its leakage rate is below 13.8%.(2) venous indwelling is stabbed for a short time at blood vessel, protects blood vessel effectively, and tube drawing reduces the destruction to blood vessel after of short duration reparation is promptly reusable.(3) venous detaining needle has reduced the patient's blood vessel puncture time, has alleviated patient's misery, has alleviated nurse's workload.(4) trocar retention time in blood vessel is longer, can accomplish venous transfusion at any time for patients such as operation, neonate, critical, rescues, guarantees treatment.(5) economical price of the trocar equates both economical practicality substantially with common scalp draw point transfusion consumptive material.
Present remaining needle mainly includes sheath, remaining needle sleeve pipe, casing seat, puncture needle tubing, infusion connector assembly, and the sleeve pipe rear end is connected with casing seat.Straight formula venous detaining needle, extract the puncture needle tubing after, the casing seat rear portion directly is connected with the infusion connector assembly and infuses.In the three way type venous detaining needle casing seat batching pig is housed also, the puncture needle tubing was inserted batching pig hermetically, was positioned at the remaining needle sleeve pipe, and the casing seat side direction is connected with transfusion three way cock assembly by connecting leg.After medical personnel use venous indwelling at the patient's vein vascular puncture, the needle tubing that will puncture is extracted from casing seat rear end and remaining needle sleeve pipe, comparatively softish sleeve portion is kept somewhere in the patient's vein blood vessel, carries out continuously to the patient or transfusion discontinuously by the remaining needle sleeve pipe.Existing most remaining needle is after extracting puncture needle, because left pin hole of puncture needle or pin seam is arranged on the batching pig, it is unreliable to seal, patient's blood can flow out from blood vessel along sleeve pipe easily, pollute the site of puncture, even infect medical personnel, to patient and medical personnel's the big harm of healthy formation machine.Excessive for preventing blood, medical personnel need push down blood vessel and sleeve pipe with finger when pulling out pin, and operation is inconvenience very, but also are to stop the blood outflow fully.
Summary of the invention
This utility model purpose is: a kind of venous detaining needle batching pig is provided, and this batching pig is simple in structure, easy to use, good airproof performance, can prevent blood seepage flow effectively.
The technical solution of the utility model is: a kind of venous detaining needle batching pig, the front end face of this batching pig is cut the cut channel of a Breadth Maximum less than the batching pig diameter backward vertically, the width of cut channel progressively diminishes after by forward direction, and the rearmost end of cut channel is near the rear end face of batching pig.
This utility model advantage is: when extracting puncture needle, cut channel of the present utility model can be sealed pin hole immediately, and sealing is reliable, and patient's blood can not flow out from blood vessel along sleeve pipe, has avoided that the site of puncture is contaminated, medical personnel are infected.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further described:
Fig. 1 is a front view of the present utility model;
Fig. 2 is the longitudinal sectional view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1.
Wherein: 1 cut channel; 2 ring grooves.
The specific embodiment
Embodiment: as Fig. 1, Fig. 2 and shown in Figure 3, a kind of venous detaining needle batching pig, the front end face of this batching pig is cut the cut channel 1 of a Breadth Maximum less than the batching pig diameter backward vertically, and the width of cut channel 1 progressively diminishes after by forward direction, and the narrowest place of cut channel 1 is near the rear end face of batching pig.
In the use, when extracting puncture needle, cut channel 1 of the present utility model can be sealed pin hole immediately, and sealing is reliable, and patient's blood can not flow out from blood vessel along sleeve pipe, has avoided that the site of puncture is contaminated, medical personnel are infected.
The middle part of described batching pig outer surface is provided with a ring groove 2, and the annular protrusion that is provided with in ring groove 2 and the casing seat cooperates, and is used for batching pig stably is fixed in the Injector Bushing base.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.In addition to the implementation, this utility model can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within this utility model scope required for protection.
Claims (2)
1. venous detaining needle batching pig, it is characterized in that: the front end face of this batching pig is cut the cut channel (1) of a Breadth Maximum less than the batching pig diameter backward vertically, and the rearmost end of cut channel (1) is near the rear end face of batching pig.
2. according to the described venous detaining needle batching pig of claim 1, it is characterized in that: the width of described cut channel (1) progressively diminishes after by forward direction.
