bloodletting tools

Abstract

The invention discloses a blood stasis and bloodletting tool, which includes a handle part, a disposable bloodletting head and a disposable blood storage tool. The handle part includes a handle, and a telescopic rod is slidably installed in the handle. Install a disposable bloodletting head for discharging blood stasis, the handle is provided with a rotating wheel, and the telescopic rod is provided with teeth meshing with the rotating wheel, and the rotating wheel drives the telescopic rod to move through the meshing with the teeth. The disposable bloodletting head includes a connecting head and a bloodletting plate for frictional wound bleeding. The other end of the handle is provided with a first threaded head, and the first threaded head is screwed to install a disposable blood storage tool. The blood stasis and bloodletting tool of the present invention solves the problem of lack of specific tools for small incision bloodletting. The tool can easily control the depth of insertion into the wound, optimizes the problem of blood stasis treatment, and reduces the qualification threshold of the operator.

Description

【Technical field】 [0001] The invention relates to the field of medical appliances, in particular to blood stasis and bloodletting tools. 【Background technique】 [0002] Whether the finger body can survive after replantation depends on whether the blood circulation of the affected finger can be re-established. Venous crisis is a common complication after replantation, manifested by swollen fingers, purple skin color, decreased skin temperature, shortened or even disappeared capillary filling time, and is often seen in severe injuries without anastomosable veins or small anastomotic veins or venous reflux Obstacles in several situations, if not treated in time, will lead to necrosis of the replanted finger body. Clinically, small incision bloodletting is often used to relieve venous vascular crisis, especially 3-5 days after operation is the critical period for the survival of severed fingers, and it is also the window period of venous crisis. Bloodletting can be stopped, an...

Problems solved by technology

[0003] This operation generally requires experienced nurses to complete smoothly. It is difficult to control the depth of the needle or tweezers into the wound.

If the needle penetrates too deeply, it will easily penetrate the papillary dermis and damage the deep tissue, resulting in delayed incision healing and increasing the patient’s discomfort such as pain

Toothed tweezers have too deep tooth lines, which will damage the incision tissue, and non-toothed tweezers have insufficient scratching and stimulation force, and the contact with the blunt surface is slightly larger, resulting in difficult bleeding or slow bleeding volume and speed, which cannot achieve the effect of draining blood stasis

Heparin cotton balls are currently used to absorb the discharged blood stasis, and suck blood while bleeding. If the adsorption is not timely, the blood stasis will flow to other parts of the finger body or even bed sheets and quilt covers, which will increase the difficulty of bloodletting and the chance of contamination.

In addition, tools need to be aseptically operated during bloodletting, and tools need to be sterilized or brand new tools are used every time they are used, which is a waste of medical resources
