Problems solved by technology

Each operation requires medical staff to fix the tourniquet on the patient's limbs with both hands. At the same time, due to the needs of individual hygiene and health, when the tourniquet is applied to other patients every time, it is necessary to disinfect the tourniquet or replace it. A new tourniquet is cumbersome to operate, and the workload of medical staff is heavy, and each person changing the tourniquet will not only increase the amount of medical waste, but also cause a waste of resources
In addition, some patients are more afraid of the blood collection process, and feel uncomfortable when they see the venipuncture blood collection during the puncture process.
At present, there is no extruding device for extremities that can simultaneously solve the above problems at home and abroad.

Embodiment approach 1

[0041] The working process of the cable tie mechanism of the device: as attached Figure 4 As shown, the cable tie (9) is in a relaxed state by the cable tie reset mechanism through the connecting strap (15), and the anchor point (14) is fixed on the cable tie reset mechanism fixing arm (17) of the device bracket (2). After the motor (12) inside the tensioning mechanism is started, the two motors (12) rotate in opposite directions and drive the corresponding rotors (18) to rotate in the same direction. The rotor rotates through the end of the cable tie (10) to rotate and tighten the cable tie ( 9) The cable tie (9) is stretched and the loop is tightened. At this time, the connecting strap (15) is stretched. When the motor (12) is reset, the cable tie (9) is restored to the relaxed position under the action of the connecting strap (15).

Embodiment approach 2

[0043] The working process of the isolation film transmission mechanism of the device: as attached Figure 5 As shown, in the non-working state, one end of the isolation membrane (16) is in a folded state (23) at the feeding end (5), and the other end at the collecting end (7). After the device is started, it is inside the collecting end (7) The motor starts to work and drives the corresponding roller (21) to rotate. The roller (21) drives the isolating film (16) to move inside. The isolating film (16) comes out of the feed end (5) and then to the collecting end (7) Move and enter the collecting end (19). When it moves to a proper length, turn off the motor.

Embodiment approach 3

[0044] Embodiment 3: It is a preferred implementation process of the upper limb elbow joint vein blood sampling of the upper limb vein extrusion of the device of the present invention.

[0045] The device is used in the operation process of extremity extrusion, as attached Figure 1-5 As shown, first adjust the angle of the device support (2) and the device base (1), then penetrate the upper limbs into the hollow (4) part of the device support, start the isolation membrane transmission mechanism, and the motor inside the collecting end (7) starts Work, drive the corresponding roller (21) to rotate, the roller (21) drives the isolation film (16) to move inside, the isolation film (16) moves from the feed end (5) to the aggregate end (7) and moves When the length is appropriate, close the transmission mechanism of the isolation membrane, start the tie-tensioning mechanism, the tie-tensioning mechanism pulls the tie (9), stretches the tie (9), and acts on the upper arm after contact...

Abstract

The invention discloses a four-limb extrusion device for medical use. The four-limb extrusion device is mainly applied to the medical conditions with need for four-limb extrusion such as venous bloodsampling, transfusion, hemostasis and the like, is characterized by being capable of replacing traditional handheld type tourniquet operation and meets the individual health demand, so that rapid extrusion for four limbs is realized, the operation process is simplified, and the diagnosis and treatment efficiency is improved.

Description

Technical field [0001] The present invention relates to a medical extremity squeezing device, which is mainly used in venous blood collection, fluid transfusion, hemostasis and other medical situations that require extremity squeezing, and at the same time meets individual hygiene needs, and belongs to the medical diagnosis and treatment field. Background technique [0002] Under normal circumstances, blood sampling or intravenous infusion of limbs requires a certain degree of squeezing of the proximal blood vessels of the veins to achieve the purpose of exposing the venous vessels and easy puncture operations. In addition, when the extremities vascular trauma bleeding, in order to achieve temporary hemostasis For the purpose, it is also necessary to squeeze the limbs. [0003] At present, in clinical practice, when venous blood collection or infusion is performed at the blood collection window of the hospital, the transfusion center, or the bedside of the ward, elastic tourniquets...
