Description
Technical field
This utility model relates to technical field of medical instruments, particularly related to one be applicable to infant negative-pressure type quiet/needle of retaining on artery.
Background technology
The existing conventional infant remaining needle used does not possess negative pressure blood return function.After venipuncture success, blood back is the impact of liquid body static pressure and infant local vessel wall elasticity, blood volume, tube chamber fullness degree, when above-mentioned factor is undesirable, and blood back difficulty; When infant local vascular does not appear again, puncture person blindly send pin, easily causes to wear by mistake, judge by accident, reduces puncture success rate.Frequent diagnostic arterypuncture blood sampling, adds the destructiveness of blood vessel simultaneously, brings difficulty to diagnosis and treatment in the future, both causes unnecessary misery to infant, affect nurse-patient relationship, and turn increased hospital costs, reduce work efficiency.
Infant is as special PATIENT POPULATION, during puncture, available blood vessel is few, and it pricks this Ink vessel transfusing after tourniquet, and to retain blood volume limited, many unsuitable blood backs, carry out moving/venous detaining needle puncture time, need another nurse to be connected syringe pump to judge success or not, both increase manpower like this, increase again the use amount of consumptive material.Complex operation simultaneously, increases nosocomial infection probability and infant medical expense.
Summary of the invention
For the deficiencies in the prior art, this utility model provide one be applicable to infant negative-pressure type quiet/needle of retaining on artery.
This utility model comprises puncture needle flexible pipe, puncture needle, needle handle, pulley-type actuator, extension tube, buckle-type actuator and Y type interface; Extension tube one end connecting puncture needle, the other end connects Y type interface, puncture needle flexible pipe is nested on puncture needle, puncture needle afterbody is provided with needle handle, extension tube is provided with pulley-type actuator and buckle-type actuator, and the distance of pulley-type actuator distance puncture needle is less than the distance of buckle-type actuator distance puncture needle.
Described pulley-type actuator comprises pulley and pulley groove, and pulley can roll along pulley groove inwall, and the length of pulley groove equals pulley circumference, and is greater than the length of puncture flexible pipe.
Described pulley groove is wedge structure, and the tip of wedge shape is near puncture needle.
Described buckle-type actuator is buckle-type actuator on conventional remaining needle.
The diameter of described extension tube tube chamber is 1.5 times of extension tube lumen diameter on conventional remaining needle.
The beneficial effect of this utility model is:
1, as needle of retaining on artery in order to reduce frequent diagnostic arterial blood drawing puncture time, protection blood vessel, is especially applied to infant that is critical, puncture difficulty, can saves therapeutic time, simultaneously infant arterial blood drawing needs operator to touch its arteriopalmus to gather, and venipuncture difficulty is larger; Tremulous pulse blood back is easy not as adult, and this Novel remaining needle sets up negative pressure blood return function, for arterypuncture successfully provides safeguard.
2, as venous detaining needle
1) be convenient in infusion process, check remaining needle whether in the unobstructed situation of Ink vessel transfusing or liquid.
2) improve the malleation effect of Catheter, avoid the blood reflux plugging after tube sealing, the positive pressure connector that disposable vein remaining needle configures can be abolished simultaneously, reduce the price more than 2 times of product.
3) omit transfusion and terminate rear tube sealing link, reduce the nosocomial infection chance brought thus.
3, carry out suction judgement due to syringe need not be connect, reduce the chance of nosocomial infection.
4, blood vessel can be reduced to damage further, alleviate infant pain, improve blood vessel availability and puncture success rate.
5, cost of manufacture is low, practical and convenient, simple to operate, safety.
6, save human and material resources, increase work efficiency.
7, operator's mental pressure is alleviated, harmonious nurse-patient relationship.
8, reduce infant medical treatment cost, avoid the wasting of resources.
Accompanying drawing explanation
Fig. 1: be this utility model structural representation;
In figure: 1 puncture needle flexible pipe, 2 puncture needles, 3 needle handles, 4 pulley-type actuators, 5 extension tubes, 6 buckle-type actuators, 7 breeches joints, 8 pulleys, 9 pulley grooves.
Detailed description of the invention
Below in conjunction with embodiment, this utility model is further described.
As shown in Figure 1, puncture needle flexible pipe 1, puncture needle 2, needle handle 3, pulley-type actuator 4, extension tube 5, buckle-type actuator 6 and Y type interface 7 is comprised; Extension tube 5 one end connecting puncture needle 2, the other end connects Y type interface 7, puncture needle flexible pipe 1 is nested on puncture needle 2, needle handle 3 is arranged on puncture needle 2 afterbody, extension tube 5 is provided with pulley-type actuator 4 and buckle-type actuator 6, and pulley-type actuator 4 is less than the distance of buckle-type actuator 6 apart from puncture needle 2 apart from the distance of puncture needle 2.
Described pulley-type actuator 4 comprises pulley 8 and pulley groove 9, and pulley 8 can roll along pulley groove 9 inwall, and the length of pulley groove 9 equals pulley 8 girth, and is greater than the length of puncture needle flexible pipe 1.
Described pulley groove 9 is wedge structure, and the tip of wedge shape is near puncture needle 2, and namely pulley 8 closing direction is by (namely the backshank of puncture needle 2 is to needle point direction) before backward.
Described buckle-type actuator 6 is buckle-type actuator on conventional remaining needle.
The diameter of described extension tube 5 tube chamber is 1.5 times of extension tube lumen diameter on conventional remaining needle.
Using method of the present utility model: 1, implement periphery venipuncture method: routine normal saline gets rid of the air in a whole set of venous indwelling needle tubing, after closing the buckle-type actuator 6 in its extension tube 5, then close the close syringe needle place as far as possible, position of this actuator of pulley-type actuator 4().Conventional puncture, when puncture needle 2 needle slope thrusts in skin completely, unclamps pulley-type actuator 4, at this moment just negative pressure can be formed in extension tube 5, continue puncture, if syringe needle enters intravenous, due to suction function, then blood back immediately, now, then open buckle-type actuator 6, while move back puncture needle 2 limit to send into puncture needle flexible pipe 1, after completing, routine disinfection breeches joint 7 connects transfusion device, carries out infusing.
2, check in transfusion: first close in extension tube 5 near transfusion device end buckle-type actuator 6, close near puncture needle 2 end extension tube 5 pulley-type actuator 4, unclamp pulley-type actuator 4 again, at this moment negative pressure is formed in extension tube 5, if syringe needle is at Ink vessel transfusing, then visible blood-flow, then unclamp buckle-type actuator 6 continuation transfusion.
3, infusion-completed Catheter: transfusion terminates two actuators in extension tube to move down as far as possible, near puncture needle 2 side, close actuator and have two kinds of methods: (1) first closes pulley-type actuator 4, blood just can clamp-on Ink vessel transfusing, when closing buckle actuator 6 again, now form malleation in official jargon, subsequently close transfusion device carries actuator, remove transfusion device, fixing venous detaining needle.(2) also two actuators in extension tube 5 can cut out simultaneously, subsequently close transfusion device carry actuator, remove transfusion device, fixing venous detaining needle.Use above-mentioned two kinds of methods can without the need to doing positive pressure tube sealing again, the positive pressure connector that disposable vein remaining needle configures be just defeasible.This method can improve the effect of Catheter malleation, avoids the blood reflux plugging after tube sealing, can abolish the positive pressure connector that disposable vein remaining needle configures simultaneously, reduces the price more than 2 times of product.
