Description

Puncture needle suitable for home use

Technical Field

The utility model relates to a human living article, in particular to a medical instrument, and particularly relates to a puncture needle suitable for being used at home.

Background

Home Hemodialysis (HD) is an end-stage renal disease (ESRD) treatment modality in which patients are self-individualized at home. Compared with the treatment of a hemodialysis center, the treatment mode improves the life quality of patients, has no risk of cross infection and effectively solves the contradiction of short supply and short demand of medical beds. The benefits of home hemodialysis compared to central dialysis are increasingly being of concern to health care providers and Hemodialysis (HD) patients.

However, in the case of the existing home hemodialysis, since the operator is mostly the patient himself and is not trained professionally, the existing hemodialysis apparatus is not convenient for the patient to operate independently and is easy to stab the patient by misoperation of the needle.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a puncture needle suitable for home use, and aims to solve the technical problems that a hemodialysis device in the prior art is inconvenient to operate by a single person and easily punctures a patient.

In order to achieve the above purpose, the utility model provides the following technical scheme:

the utility model provides a pjncture needle that is fit for use at home, includes a needle tubing, the head of needle tubing be provided with a syringe needle, the syringe needle be provided with a needle cap outward, the needle tubing on from the head to the afterbody have a pair of stationary vane, a protective sheath, a medicine feeding component, a switch to press from both sides in proper order, the stationary vane use the axle center of needle tubing set up as symmetry axis symmetry the outer wall of needle tubing on, the stationary vane be close to the syringe needle, the protective sheath be hollow tubulose, the protective sheath on follow the axial of needle tubing be provided with two draw-in grooves, the draw-in groove open in its with the terminal surface that the needle phase is in, medicine feeding component include a body, the body cover establish the needle tubing outside, the body on radially be provided with a medicine feeding pipe to the outside, medicine feeding pipe with the body intercommunication, the tail end of the administration tube is provided with a leakage-proof membrane, and the tail part of the needle tube is provided with a connecting screw cap.

Further, the axial direction of the administration tube is vertical to the axial direction of the tube body.

Furthermore, the needle head is a blunt puncture needle head.

The working process is as follows:

the needle cap is arranged outside the needle head during normal storage, and the clamping groove of the protective sleeve penetrates through the fixing wing, so that the outer shell of the protective sleeve is coated on the outer sides of the needle head and the needle cap, and the condition of needle head puncture is prevented. During the use, take off the syringe needle, be connected connecting nut and the medical equipment who corresponds, move back the protective sheath outside the stationary vane, pierce the puncture point with the syringe needle, fix the syringe needle on the skin surface through stationary vane and fixed subsides can.

The auxiliary medicament can be injected through the administration tissue as required, the auxiliary medicament is absorbed into a needle cylinder firstly, then the needle head of the needle cylinder is inserted into the needle cylinder through the administration tube, the auxiliary medicament is fed into the needle cylinder and then the needle head of the needle cylinder is pulled out, and the leakage-proof film is used for preventing the medicament in the needle cylinder from leaking out of the needle cylinder. The transfusion can be stopped at any time through the switch clamp according to the disease condition and the transfusion progress.

After hemodialysis is completed, the switch clamp is clamped, the needle head is extracted, the clamping groove of the protective sleeve penetrates through the fixing wing, the outer shell of the protective sleeve is wrapped outside the needle head, and the condition that the needle head is punctured in the subsequent picking process is prevented.

Compared with the prior art, the utility model has the beneficial effects that: 1. the components needing to be operated are integrated together, so that the home hemodialysis can be independently completed when a patient is at home; 2. the protective sleeve can effectively prevent an unskilled patient from being punctured by the needle.

Detailed Description

Example 1

Referring to fig. 1 and fig. 2, the present invention provides a technical solution:

a puncture needle suitable for household use comprises a needle tube 1, the head of the needle tube 1 is provided with a needle head 2, the outside of the needle head 2 is provided with a needle cap 3, the needle tube 1 is sequentially provided with a pair of fixed wings 4 and a protective sleeve 5 from the head to the tail, a send medicine subassembly 6, a switch clamp 7, stationary vane 4 uses the axle center of needle tubing 1 as symmetry axis symmetry setting on the outer wall of needle tubing 1, stationary vane 4 is close to syringe needle 2, protective sheath 5 is hollow tubulose, protective sheath 5 is last to be provided with two draw-in grooves 51 along the axial of needle tubing 1, draw-in groove 51 is open in its terminal surface opposite with syringe needle 2, send medicine subassembly 6 to include a body 61, body 61 cover is established in the needle tubing 1 outside, be provided with a pipe 62 of dosing on the body 61 along radial outside side, pipe 62 and body 61 intercommunication of dosing, the end of pipe 62 of dosing is provided with a leak protection membrane 63, the afterbody of needle tubing 1 is provided with a coupling nut 8.

Further, the axial direction of the administration tube 62 is perpendicular to the axial direction of the tube body 61.

Further, the needle 2 is a blunt puncture needle. The length of the needle head is longer than that of a conventional needle head, so that the autonomous operation of a patient is facilitated.

The working principle of the embodiment is as follows:

when preserving at ordinary times, the syringe needle 2 is provided with the needle cap 3 outward, and draw-in groove 51 of protective sheath 5 passes stationary vane 4, makes the shell cladding of protective sheath 5 in the outside of syringe needle 2 and needle cap 3, prevents the situation that takes place syringe needle 2 stabbing. During the use, take off syringe needle 2, be connected connecting nut 8 and the medical equipment who corresponds, move back protective sheath 5 outside stationary vane 4, pierce the puncture point with syringe needle 2, fix on the skin surface through stationary vane 4 and fixed subsides with syringe needle 2 can.

The auxiliary agent can be injected through the administration tissue 6 as required, the auxiliary agent is absorbed into a syringe, the needle of the syringe is penetrated into the needle tube 1 through the administration tube 62, the auxiliary agent is fed into the needle tube 1, and then the needle of the syringe is pulled out, and the leakage-proof film 63 is used for preventing the agent in the needle tube 1 from leaking out of the needle tube 1. The transfusion can be stopped at any time through the switch clamp 7 according to the disease condition and the transfusion progress.

After hemodialysis, press from both sides the switch and press from both sides 7, extract syringe needle 2, the draw-in groove 51 of protective sheath 5 passes stationary vane 4, makes the shell cladding of protective sheath 5 in the syringe needle 2 outside, prevents that follow-up picking-up in-process from taking place the situation that syringe needle 2 stabbed.

Specifically, the leakproof film 63 and the fixing of the puncture needle by the fixing wings and the fixing patch are conventional practice for those skilled in the art, and will not be described herein.
