Abstract
This utility model belongs to technical field of medical instruments, particularly a kind ofly just takes and thrusts the blood taking needle of depth adjustable.This is just taken and the blood taking needle thrusting depth adjustable comprises shank and syringe needle, it is characterized in that: with external screw thread outside described shank, shank is connected with the female casing threads of medial wall band, that end opening that sleeve pipe is passed by syringe needle, opening part is provided with projection, be provided with elastomeric element inside sleeve pipe, outside of sleeve surface is the rubbing surface of treated increase coefficient of friction.Structure is simple, easy to use; Shank is connected with casing threads, regulates needle body to thrust the degree of depth of human body, decrease the misery of human body by revoling tube; Elastomeric element is provided with, even if stripped thread also can be regulated by elastomeric element thrust human depth in sleeve pipe; Cost is low, easy to utilize.
Description
(1) technical field
This utility model relates to a kind ofly just to be taken and thrusts the blood taking needle of depth adjustable, belongs to technical field of medical instruments.
(2) background technology
Blood taking needle is doctor's requisite instrument when taking a blood sample, in order to meet the needs of different parts blood sampling, the length of needle body differs, thus blood taking needle includes plurality of specifications, if doctor does not look easily to slip out of the hand when changing the blood taking needle of different model, and differ due to the acupuncture treatment maneuver weight of doctor, for same blood sampling site, different people's operations, the degree of depth that needle body thrusts human body is also different, and some meetings are pricked shallow, make to adopt less than blood, some meetings are pricked dark, and bring larger pain to patient, it is just right seldom to accomplish.
(3) summary of the invention
This utility model, in order to make up the defect of prior art, provides a kind of structure simple, easy to use just take and thrusts the blood taking needle of depth adjustable.
This utility model is achieved by the following technical solution:
A kind ofly just take and thrust the blood taking needle of depth adjustable, comprise shank and syringe needle, it is characterized in that: with external screw thread outside described shank, shank is connected with the female casing threads of medial wall band, that end opening that sleeve pipe is passed by syringe needle, opening part is provided with projection, is provided with elastomeric element inside sleeve pipe, and outside of sleeve surface is the rubbing surface of treated increase coefficient of friction.
Wherein:
Projection is touched in described elastomeric element one end, and the other end touches the end of shank.
Described elastomeric element is spiral spring.
This utility model shank is connected with casing threads, the degree of depth of thrusting human body is regulated by revoling tube, decrease human body because thrust dark misery, and be provided with elastomeric element in sleeve pipe, even if shank and sleeve pipe stripped thread also can be regulated by elastomeric element and thrust the degree of depth, extend service life of the present utility model; Outside of sleeve surface is the rubbing surface of treated increase coefficient of friction, makes not easily to slip out of the hand in this utility model use procedure.
The beneficial effects of the utility model are: structure is simple, easy to use; Shank is connected with casing threads, regulates needle body to thrust the degree of depth of human body, decrease the misery of human body by revoling tube; Elastomeric element is provided with, even if stripped thread also can be regulated by elastomeric element thrust human depth in sleeve pipe; Cost is low, easy to utilize.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, this utility model is further described.
Accompanying drawing 1 is that this utility model is just taken and thrusts the blood taking needle structural representation of depth adjustable.
In figure: 1, shank; 2, syringe needle; 3, sleeve pipe; 4, protruding; 5, spiral spring.
Detailed description of the invention
Accompanying drawing is specific embodiment of the utility model.
This utility model as shown in Figure 1 is just taken and is thrust the blood taking needle of depth adjustable, comprise shank 1 and syringe needle 2, with external screw thread outside described shank 1, shank 1 is threaded with the female sleeve pipe 3 of medial wall band, that end opening that sleeve pipe 3 is passed by syringe needle 2, and opening part is provided with protruding 4, spiral spring 5 is provided with inside sleeve pipe 3, sleeve pipe 3 outer surface is the rubbing surface of treated increase coefficient of friction, and spiral spring 5 one end touches protruding 4, and the other end touches the end of shank 1.
This utility model shank 1 is threaded with sleeve pipe 3, the degree of depth of thrusting human body is regulated by revoling tube 3, decrease human body because thrust dark misery, and be provided with spiral spring 5 in sleeve pipe 3, even if shank 1 and sleeve pipe 3 stripped thread also can be regulated by spiral spring 5 thrust the degree of depth, extend service life of the present utility model; Sleeve pipe 3 outer surface is the rubbing surface of treated increase coefficient of friction, increases the frictional force between sleeve pipe 3 and hands, makes be affectedly bashful convenient in this utility model use procedure and not easily slip out of the hand.
