Description
Technical field
The present invention relates to medical treatment, care tool technical fields, and in particular to one kind being used for local anaesthesia or lipolyse, glass
The injections blunt needles such as uric acid, PRP injections.
Background technology
In the prior art, injection needle traditional in beauty treatment clinic is using the puncture injections such as muscle, subcutaneous, due to tradition
The front end of injection needle is cone sword, and front end is directly provided with infusion of medicine hole, in puncture injection since dynamics is grasped not
Enough accurate, injection pressure transmission speed is too fast, and drug equally discharges too fast during pushing, and often causes needle stick injuries blood
Pipe and nerve or drug are too fast by injection pressure transmission speed, cause moment to operative site or surrounding tissue, blood vessel and
The damage of nerve, so as to cause making some operations that there is certain risk.
Invention content
It is an object of the present invention to overcome defect existing in the prior art, provide it is a kind of it is simple in structure, easy to use,
Good operation effect, can make solvent, medicament will not quickly but at leisure by being sprayed in hole, do not oppress hurt nerve and
Blood vessel hardly brings any burden to human body.It can injection blunt needle that equably large area is injected.
To achieve the above object, the technical scheme is to design hypodermic injection blunt needle, the top of the blunt needle is
Smooth surface body, smooth surface body are equipped with the oval interior table in outer surface using lower part as pipe structure on the tube wall of tube body
The side view of the rounded through-hole in face, through-hole is in dome-shaped, and the blunt needle is made of semi-rigid material, and the arbitrary portion of tube body
Potential energy bending is to 90 °.The injection blunt needle is mainly characterized by the rounded hole of the oval inner surface in outer surface, it and one
As injection needle circular hole it is different.Any part of tube body curves 90 degree, and medicament will not block, and tube body can be with operator
Member controls, and thinks where be bent with regard to where being bent.
In order to avoid single through-hole also needs to confirm the trouble that injected material is projected by which direction, preferred skill in injection
Art scheme is to be equipped with 2~4, and 2~4 in the rounded through-hole of the oval inner surface of tube wall upper outer surface of the tube body
The rounded through-hole of a oval inner surface in outer surface is near the top of blunt needle.
It can be slowly by being flowed out in through-hole for the ease of control injected material, further preferred technical solution is in addition, institute
The rounded through-hole of the oval inner surface in outer surface is stated, elliptical long axis is parallel with the axis of tube body.
It can be slowly by being flowed out in through-hole for the ease of control injected material, further preferred technical solution is in addition, institute
The rounded through-hole of the oval inner surface in outer surface is stated, elliptical long axis is helically arranged on the surface of tube body.
In order to ensure tube body can carry out bending in any part, and tube wall will not rupture after bending, and injected material energy
It is enough successfully to flow through bending part, it for the ease of injection, and operating personnel can control at one's discretion, and can be always maintained at light
The posture of pine operates, and further preferred technical solution is in addition, the semi-rigid material is Japan steel SUS304DE.Day
The steel SUS304DE of this system is not only thin but also secured.Arbitrarily needle can be bent, highest can be bent to 90 degree.
For the ease of the company of the body portion of injection blunt needle and the injection storage chamber of syringe and injection propulsive units
It connects, preferred technical solution is in addition, the other end in the tube body is equipped with the conical pipe for transition connection.
Smooth in order to ensure tube surfaces, further preferred technical solution is in addition, the outer surface of the blunt needle is passed through
The processing of polishing treatment technique.
The advantages of the present invention are：The injection blunt needle has simple in structure, easy to use, surgical effect
It is good, solvent, medicament can be made not to oppress quickly but at leisure by being sprayed in hole and hurt nerve and blood vessel, it is several
Any burden will not be brought to human body, it can the features such as equably large area is injected.Since the present invention is in tube surfaces
What is opened up is the rounded through-hole of the oval inner surface in outer surface, not only long but also narrow compared with general circular through hole, so molten
Agent, medicament will not be flowed out, but be sprayed at leisure quickly, hardly bring burden to human body.And one shares 2~4
It, can equably large area be injected to skin in the rounded through-hole of the oval inner surface in outer surface that rotary is distributed.
Each commodity can be checked before sterilization treatment, so will not there is a phenomenon where through-holes to block.In addition, due to tube body material
The steel SUS304DE for having used Japanese system can be accomplished not only thin but also secured using tube body made of this material.It can be arbitrary
Tube body is bent, highest can be bent to 90 degree, no matter operator controls, and can be always maintained at easily posture and come
Shi Shu.Since the top of the injection blunt needle is rounded, nerve and blood vessel will not be hurt, it is existing internal haemorrhage pain will not occur
As.That is almost painless.If in the case of only 1 through-hole, solvent gushes out from which direction and needs to confirm after insertion,
But in the case of 4 through-holes or 2 through-holes, operator be not necessarily to confirm the position in hole ready for insertion into.The injection
Blunt needle can be used in the fields such as local anaesthesia or lipolyse injection, sodium hyaluronate injection, PRP injections and be widely used.If with
If injecting blood vessel when sodium hyaluronate is injected, angionecrosis can be caused, but it is such to have used this injection blunt needle that would not occur
Thing.Can be to avoid internal haemorrhage using it, necrosis, the appearance of the symptoms such as pain.
