Description

Hemodialysis pjncture needle of removable fraction of syringe needle

The technical field is as follows:

the utility model relates to the field of medical equipment, mainly relate to a removable fraction hemodialysis pjncture needle of syringe needle.

Background art:

hemodialysis pjncture needle is an indispensable medical instrument in hemodialysis treatment. The puncture needle at the present stage is mostly produced by adopting a standard method, and needs to be placed in a storage box after being used, so that the puncture needle is prevented from being hurt by a sharp device to workers. The existing puncture needles are mostly produced according to the standard, a hose with a long end is arranged below the needle head, the number of the needle heads placed into the storage box is greatly influenced, and medical workers are stabbed outside the storage box to cause needle stick injuries due to the fact that the long needle head of the hose is tilted and exposed outside the storage box in serious cases. In daily use, the puncture needle is also cut off to be placed in the storage box, but blood fluid splashing of a patient in the hose easily causes environmental pollution of a treatment area or infection of workers, so that the structure of the puncture needle needs to be improved, and the puncture needle can meet the requirements of convenient use and collection.

The utility model has the following contents:

the utility model discloses the purpose is exactly in order to remedy prior art's defect, provides a but syringe needle split hemodialysis pjncture needle, after the use, the accessible is placed to its split after reclassification, has not only satisfied the purpose of categorised collection, makes things convenient for manual operation moreover, and the blood at both ends can not drip, has avoided patient's in the hose blood body fluid to splash and has caused treatment area environmental pollution or staff's infection.

The utility model discloses a realize through following technical scheme:

the utility model provides a syringe needle detachable type hemodialysis pjncture needle which characterized in that: the hose including two butt joints, the hose is including nozzle stub and long tube, the needle handle is installed to the money tip of nozzle stub, the hose of tip is connected with the syringe needle through the spliced pole before the needle handle, the cover is equipped with the syringe needle protective sheath on the syringe needle, the end of nozzle stub is equipped with the step face, the step is equipped with the ring channel along the axial setting in the face, the cooperation of pegging graft of ring channel and the preceding tip of long tube, the back tip of step face and long tube is equipped with the external screw thread respectively, and closes soon on the external screw thread and have the adapter sleeve, the adapter sleeve has certain tapering, the rear end portion of long tube is installed and is only flowed and press from both sides.

The inside wall of syringe needle protective sheath and the suit cooperation punishment of syringe needle spliced pole distribute the draw-in groove that the interval set up, the card is equipped with the sealing strip in the draw-in groove.

The annular groove is matched with the long pipe, the diameter of the inner circumference of the step surface is smaller than the inner aperture of the long pipe, and the diameter of the outer circumference of the step surface is larger than the outer aperture of the long pipe.

The inner circumferential surface and the outer circumferential surface of the front end part of the long pipe are respectively provided with annular sealing convex ribs which are arranged in a staggered mode.

The principle is as follows: through the structural design of the hose of dock, can carry out the split to it after its use finishes, at first close the end flow clamp during split, then carry out gas seal state to the syringe needle through the syringe needle protective sheath, thereby certain air pressure has been guaranteed, the syringe needle can not drip after the split from the pjncture needle, the advantage that prevents that the pjncture needle raffinate from arousing the infection has been realized, later revolve wrong adapter sleeve of twisting butt joint department again, thereby make nozzle stub and long-tube butt joint be in simple grafting state, can carry out the split to it, syringe needle after the split, needle handle and nozzle stub can be followed the pjncture needle and split and place the receiver alone and be difficult for receiving the pipe influence perk, the advantage of easy safe storage of pjncture needle has been realized, all the other parts are abandoned, the operation of categorised collection.

The utility model has the advantages that:

the utility model has the advantages of reasonable design, the accessible is placed to reclassification after its split, has not only satisfied the purpose of categorised collection, makes things convenient for manual operation moreover, and the blood at both ends can not drip, has avoided patient's in the hose blood body fluid splash to cause treatment area environmental pollution or staff's infection, has satisfied facilitates the use and has collected the requirement.

Description of the drawings:

fig. 1 is a schematic structural diagram of the present invention.

The specific implementation mode is as follows:

see the drawings.

The utility model provides a removable fraction hemodialysis pjncture needle of syringe needle, is including the hose of two butt joints, the hose is including nozzle stub 1 and long tube 2, needle handle 3 is installed to the coin tip of nozzle stub 1, the hose of tip is connected with syringe needle 4 through spliced pole 11 before the needle handle 3, the cover is equipped with syringe needle protective sheath 5 on the syringe needle 4, the end of nozzle stub 1 is equipped with step face 6, be equipped with ring channel 7 along the axial setting in the step face 6, ring channel 7 is pegged graft the cooperation with the preceding tip of long tube 2, the back tip of step face 6 and long tube 2 is equipped with the external screw thread respectively, and closes soon on the external screw thread and have adapter sleeve 7, adapter sleeve 7 has certain tapering, only flow clamp 8 is installed to the back tip of long tube 2, connector 9 is installed to the terminal tip of.

The inside wall of syringe needle protective sheath 5 and the suit cooperation punishment of syringe needle spliced pole 11 distribute the draw-in groove that the interval set up, the card is equipped with the sealing strip in the draw-in groove. This construction allows for stability and sealing between the needle shield and the connecting post 11.

The annular groove 7 is matched with the long pipe 2, the diameter of the inner circumference of the step surface 6 is smaller than the inner aperture of the long pipe 2, and the diameter of the outer circumference of the step surface 6 is larger than the outer aperture of the long pipe 2. Under the condition of guaranteeing mutual communication between the whole pipe bodies, the structure guarantees the matching of the pipe diameters, and can guarantee the matching of the pipe diameters when being conveniently inserted, thereby avoiding the influence on blood flow caused by the reduction of the pipe diameters.

The inner circumferential surface and the outer circumferential surface of the front end part of the long tube 2 are respectively provided with annular sealing convex ribs 10 which are arranged in a staggered way. The sealing performance at the butt joint can be enhanced.

The above-mentioned embodiment is only the preferred embodiment of the present invention, and is not to the limitation of the technical solution of the present invention, as long as the technical solution can be realized on the basis of the above-mentioned embodiment without creative work, all should be regarded as falling into the protection scope of the right of the present invention.
