Description
Technical field
The present invention relates to a kind of syringe, the disposable intervention Medical treatment device of the processes such as clinical transfusion, sampling, puncture is applied to
Tool field.
Background technology
Transfusion injection, to puncture the PCIs such as sampling be indispensable, main treatment means in clinical treatment.But note
Utensil is that patient fears and avoid one of factor for the treatment of to the pain destroyed and its cause of skin histology during being shot through thorn.
In general, the mankind will be inoculated with various vaccines from birth beginning, occur to need the doctors such as various punctures and injection when various diseases are hindered
Treat treatment.Injection, puncture pain and the body injury for being effectively reduced operation receiveing person are the Main ways of current medical apparatus research
One of.
Simultaneously in order to prevent cross-infection, the destruction structural strength of the disposable syringe carried out at present is big, the knot of core bar
Plate body also constitutes the reinforcement of the body of rod in structure, therefore needs larger power by easy breaking type core bar bending, and could to be extremely difficult to
The purpose for fractureing.
The content of the invention
It is an object of the invention to provide a kind of syringe, solution disposable syringe acupuncture pain is strong, use rear palm
Be inconvenient to the problem destroyed.
To achieve the above object, the technical solution adopted in the utility model is：
Syringe, including push rod, cylinder and syringe needle, the outer surface of metal pipe of the syringe needle are provided with rule and radially divide along syringe needle
The concave convex texture of cloth, the neighboring edge of the concave convex texture is round and smooth without corner angle；Insert the medicinal liquid cavity of cylinder, push rod in one end of push rod
Front end set seal, seal forms sealing and coordinates with the inwall of medicinal liquid cavity, and described syringe needle is set in the front end of cylinder.
Preferably, push rod includes preceding push rod, connector and rear push-rod, the preceding push rod sets company with the junction of rear push-rod
Junctor, preceding push rod shrinks tapered simultaneously with rear push-rod in connector, and the connector is arranged on the cone of preceding push rod and rear push-rod
Push rod and rear push-rod before being connected at shape.
Preferably, the concave convex texture of the outer surface of metal pipe of syringe needle is the spiral around metal tube, thread groove
Cross section is circular arc.
Preferably, preceding push rod is intersected by two panels plate body and is constituted and is formed tapered end face one in rearward end, it is described after
Push rod is intersected by two panels plate body and constitutes and form taper surface two in leading section, and the connector is arranged on end face one and end face
Between two.
Preferably, the connector is the column of diameter 1mm 3mm long, cut channel is provided with the middle part of connector.
As preferred：One week of the seal sets irregular radial seal lines, and sealing lines is under cylinder extruding
By the anterior medicinal liquid cavity and rear closure of cylinder.
It is further preferred：The seal is silica gel.
The utility model has the advantage of：Sharp needle point cuts skin, syringe needle and skin open in regular injection, puncture process
Tissue produces frictional resistance, and pain is mainly derived from needle point to the stimulation of nerve endings, syringe needle and skin histology friction and its glutinous
It is stagnant to involve the effect such as nerve stimulation, sensitivity of foreign materials for causing.Syringe needle with threaded form disclosed by the invention, can subtract
Syringe needle and the contact area of skin histology in injection puncture process, eliminate the poly- of the stress stimulation that continuous viscid friction causes less
Collect and reduce its stimulus intensity and reduce pain.Simultaneously at push rod using the structure that easily snaps off, fractureed institute than existing structure
Need power smaller.

Specific embodiment
Structure of the present utility model is as illustrated, syringe, including push rod, cylinder 4 and syringe needle 1, the metal of the syringe needle 1
The outer surface of pipe 2 is provided with rule along the radially-arranged concave convex texture 3 of syringe needle, and the neighboring edge of the concave convex texture 3 is round and smooth without corner angle；
The medicinal liquid cavity 7 of cylinder 4 is inserted in one end of push rod, and the front end of push rod sets sealing, and 5, seal 5 forms close with the inwall of medicinal liquid cavity 7
Envelope coordinates, and described syringe needle 1 is set in the front end of cylinder 4.Push rod includes preceding push rod 6, connector 8 and rear push-rod 9, the preceding push rod
6 set connector 8 with the junction of rear push-rod 9, and preceding push rod 6 shrinks tapered simultaneously with rear push-rod 9 in connector, the connector
8 are arranged at the taper of preceding push rod and rear push-rod push rod and rear push-rod before connection.
The concave convex texture that the metal tube appearance of syringe needle is bought is the spiral around metal tube, and thread groove cross section is
Circular arc.Preceding push rod is intersected by two panels plate body and constitutes and form tapered end face one in rearward end, and the rear push-rod is by two panels
Plate body is intersected and constitutes and form taper surface two in leading section, and the connector is arranged between end face one and end face two.
Connector is the column of diameter 1mm 3mm long, and cut channel is provided with the middle part of connector.One week of seal is provided with recessed
Convex radial seal lines, sealing lines is under cylinder extruding by the anterior medicinal liquid cavity and rear closure of cylinder.Seal is silicon
Glue.
Syringe needle metal tube surface screw thread can be equidistant single thread, or many screw threads of displacement on same syringe needle；Spiral shell
Groove depth scope is 0. 01-0. 10mm;The width of thread is 0. 02-0. 50mm;Pitch is more than 1mm, until screw thread becomes
Injection wire surface is along strip；The distribution of syringe needle screw thread can occupy whole needle tubing surfaces, or part.
In Clinical practice, because the continuous groove on needle tubing surface is acted on, actually connecing for syringe needle and skin histology is reduced
Contacting surface is accumulated, and the continuous friction of syringe needle and skin histology is changed into interruption friction, can effectively reduce skin histology to syringe needle table
Stagnant frictional resistance and the stimulation to underlying nerve tip are led in sticking together for face.Injection needle application method disclosed by the invention and routine
Injection needle is as good as, and patient uses no SOR, for puncturing frictional resistance due to reducing by patient, is capable of achieving to subtract pain
Effect.
