Abstract
The utility model discloses a kind of venous detaining needles of the fluted batching pig of band, it include casing seat, the front end of described sleeve pipe seat is equipped with steel needle, batching pig is equipped in described sleeve pipe seat, the outer wall of the batching pig and the inner wall of casing seat are bonded, the rear end of the batching pig is equipped with groove, and the centre of the groove is equipped with a kerf, and the front end of the batching pig is equipped with duckbill valve.The utility model is by the structure of optimization batching pig, and by groove design to an access is provided during the puncture needle withdraw of the needle, when extracting puncture needle, groove both sides notch can seal rapidly needle mouth, sealed reliable；While duck mouth valve structure can further reduce withdraw of the needle power simultaneously, closely sealed performance ensure that, and promote compressive resistance, medical staff is avoided to encounter the puckery problem of the withdraw of the needle when pulling out needle, guarantee the leakproofness of batching pig, improves batching pig compression resistance to mitigate patient suffering, avoid conflict between doctors and patients.
Description
Technical field
The utility model relates to a kind of medical supplies, especially venous detaining needle.
Background technique
Remaining needle is a kind of medical instrument for vein detaining needle for fluids infusion, as the regeneration product of scalp acupuncture, due to operation
Simply, easy to use, medication is carried out to sick body, nutrition is provided, while can to avoid injury of blood vessel caused by multiple puncture and
The pain for mitigating patient both can be reduced patient and protect blood vessel well because of the pain punctured repeatedly, and can guarantee treatment, mitigate shield
The workload of scholar, is clinically widely used.The needle assemblies of remaining needle specifically include that conduit, catheter block, puncture needle,
Paracentesis needle holder.Structure is to apply glue and be pressed into catheter block in the periphery of batching pig, by between batching pig and catheter block
Bonding force and interference fit carry out increasing friction force, form Hermetical connecting structure, and the fluid seepage in casing seat is prevented to come out, thus
Guarantee the security and reliability of remaining needle work when infusion.But in clinical use find needle tubing plug when tube body and batching pig it
Between because frictional force is larger, it is puckery to lead to the problem of the withdraw of the needle, when withdraw of the needle can cause it is micro- quiver, be easy that patient is made not feel good, to influence
Patient's treatment and generation conflict between doctors and patients.
Utility model content
Technical problem to be solved by the utility model is: providing a kind of batching pig of Novel structure, pushing away for remaining needle is reduced
The puckery problem of needle.
The solution that the utility model solves its technical problem is: a kind of venous detaining needle of the fluted batching pig of band,
It include casing seat, the front end of described sleeve pipe seat is equipped with steel needle, is equipped with batching pig, the outer wall of the batching pig in described sleeve pipe seat
It is bonded with the inner wall of casing seat, the rear end of the batching pig is equipped with groove, and the centre of the groove is equipped with a kerf, described
The front end of batching pig is equipped with duckbill valve.
As a further improvement of the above technical scheme, the escape groove of annular is equipped in the middle part of the periphery of the batching pig.
As a further improvement of the above technical scheme, the depth of the notch is the 1/2~3/4 of batching pig length.
As a further improvement of the above technical scheme, the outer application of the notch has lubricant layer.
The beneficial effects of the utility model are: the utility model is given by the structure of optimization batching pig by groove design
An access is provided during the puncture needle withdraw of the needle, groove both sides notch can seal rapidly needle mouth when extracting puncture needle, and sealing can
It leans on；While duck mouth valve structure can further reduce withdraw of the needle power simultaneously, closely sealed performance ensure that, and promote compressive resistance,
Avoid medical staff from encountering the puckery problem of the withdraw of the needle when pulling out needle, guarantee the leakproofness of batching pig, improve batching pig compression resistance to
Mitigate patient suffering, avoids conflict between doctors and patients.
Detailed description of the invention
It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described.Obviously, described attached drawing is a part of the embodiment of the utility model, rather than complete
Portion's embodiment, those skilled in the art without creative efforts, can also be obtained according to these attached drawings it
His design scheme and attached drawing.
Fig. 1 is the overall schematic of the utility model；
Fig. 2 is the stereoscopic schematic diagram of the batching pig of the utility model.
Specific embodiment
It is carried out below with reference to technical effect of the embodiment and attached drawing to the design of the utility model, specific structure and generation
It clearly and completely describes, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment
It is a part of the embodiment of the utility model, rather than whole embodiments, it is based on the embodiments of the present invention, the skill of this field
Art personnel other embodiments obtained without creative efforts belong to the model of the utility model protection
It encloses.In addition, all connection/connection relationships being previously mentioned in text, not singly refer to that component directly connects, and referring to can be according to specific reality
Situation is applied, by adding or reducing couple auxiliary, to form more preferably coupling structure.Each technology in the invention is special
Sign, can be with combination of interactions under the premise of not conflicting conflict.
Referring to Fig.1~Fig. 2, a kind of venous detaining needle of the fluted batching pig of band, includes casing seat 1, described sleeve pipe seat 1
Front end be equipped with steel needle 2, batching pig 3 is equipped in described sleeve pipe seat 1, the outer wall of the batching pig 3 is Nian Jie with the inner wall of casing seat 1
Together, the rear end of the batching pig 3 is equipped with groove 31, and the centre of the groove 31 is equipped with a kerf, the front end of the batching pig 3
Equipped with duckbill valve 32.Batching pig groove is to open the groove of a 2mm × 0.5mm in the rear surface of batching pig, and go deep into batching pig.
Batching pig upper surface is then duck mouth valve structure, has a gap at flat valve nozzle, and valve body is passed through when the puncture needle withdraw of the needle, should
Gap is opened, and steel needle passes through valve body；When needle point exits, and valve body stops working, the inside and outside pressing weighing apparatus of valve body or external pressure are big
When internal pressure, gap prevents medium back flow inlet valve body, has the function that non-return by elastic force and the lower closure of external pressure effect.Groove
Ingenious combination with duckbill valve can ensure that adaptation while further decreasing withdraw of the needle power, improve the pressure resistance of batching pig
Ability.
It is further used as preferred embodiment, the escape groove 33 of annular is equipped in the middle part of the periphery of the batching pig 3.Pass through
