Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Referring to fig. 1 and 2, the transfusion auxiliary hemostatic clamp comprises a first clamping rod 1 and a second clamping rod 12, wherein the first clamping rod 1 comprises a first lower arm 11 and a first upper arm 12, the second clamping rod 12 comprises a second lower arm 21 and a second upper arm 22, the middle parts of the first lower arm 11 and the second lower arm 21 are hinged, the first upper arm 12 and the second upper arm 22 are of an inward-bent C-shaped structure, a first pressure pad 13 is arranged at one end, away from the first lower arm 11, of the first upper arm 12, the first pressure pad 13 is planar and made of soft silica gel materials, a second pressure pad 23 is arranged at one end, away from the second lower arm 21, of the second upper arm 22, and the second pressure pad 23 is of a thumb-shaped protruding structure and made of soft silica gel materials.

After the transfusion to the back of the hand of the patient is finished, the medical staff holds the first lower arm 11 and the second lower arm 21 by hands to clamp the palm of the patient after transfusion, the first pressure pad 13 abuts against the palm of the patient, the second pressure pad 23 abuts against the eye of the patient, and the second pressure pad 23 can simulate the thumb of the medical staff and help the patient press the eye of the patient comfortably for a period of time to prevent the eye of the patient from bleeding due to the fact that the second pressure pad 23 is of a thumb-shaped protruding structure and made of soft silica gel material. The device can help patients with lower blood platelets, weak bodies or hemiplegia to press the back of the hand after transfusion, thereby not only reducing the burden of the upper limbs of the patients, saving the physical strength of the patients, but also reducing the burden of medical care personnel.

In addition, the first upper arm 12 and the second upper arm 22 are arranged into an inward-bent C-shaped structure, the two ends of the structure are small, the middle of the structure is large, and the palm of a patient can be conveniently placed in the structure. By arranging the second pressure pad 23 to be a thumb-shaped protruding structure and made of soft silicone material, accurate pressing of the needle eye position is facilitated.

Preferably, the first clamping rod 1 and the second clamping rod 12 are made of medical plastics or medical stainless steel materials, so that medical staff can conveniently use the medical clamping device, and the medical plastics and the medical stainless steel have good rigidity and toughness, so that when the first pressure pad 13 and the second pressure pad 23 are separated, the medical clamping device has larger elasticity, and can further help a patient to press the needle eye comfortably.

Referring to fig. 1 to 3, the middle portions of the first clamping rod 1 and the second clamping rod 12 are hinged to each other through a rotating shaft 3 and a torsion spring 4 sleeved on the rotating shaft 3, and two ends of the torsion spring 4 respectively abut against the inner sides of the first lower arm 11 and the second lower arm 21. The size of the clamping force between the first clamping rod 1 and the second clamping rod 12 can be controlled by selecting the torsion springs 4 with different specifications; also can select suitable material to change the size of clamping-force between first clamping rod 1 and the second clamping rod 12 through first clamping rod 1 and second clamping rod 12, the clamping-force sign is in first clamping rod 1 or second clamping rod 12 outside to distinguish, make this device be applicable to different crowds.

Preferably, the first lower arm 11 and the second lower arm 21 are plate-shaped structures in order to facilitate abutment of both ends of the torsion spring 4.

In addition, through setting up the supplementary hemostatic clamp of infusion and loosening the state, the interval size of first pressure pad 13 and second pressure pad 23 can make this device be applicable to different crowds.

In order to improve the comfort of the patient using the device, the first pressure pad 13 is circular in shape and has a radius of 20mm to 30mm, so that the first pressure pad 13 is well adapted to the palm of the patient.

Example 1: under the supplementary hemostatic clamp of infusion unclamped the state, the interval of first pressure pad 13 and second pressure pad 23 is for setting to 10mm to 15mm, and the clamping-force between first clamping rod 1 and second clamping rod 12 sets to 5 to 15N, is applicable to the infant to avoid the too big influence infant's palm of pressure.

Example 2: under the supplementary hemostatic clamp of infusion unclamped the state, the interval of first pressure pad 13 and second pressure pad 23 is 15mm to 25mm, and the clamping-force between first clamping rod 1 and second clamping rod 12 is 15 to 25N, is applicable to adult to it can not reach the effect of pressing to avoid the pressure undersize.

It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
