Screw type compression hemostat with universal pressing plate and magnetic needle indication

Abstract

The invention discloses a screw type compression hemostat with a universal pressing plate and magnetic needle indication. The screw type compression hemostat comprises a screw (1), a ball mortar (2), a joint (3), a pressing plate (4), a base (5) and an anchor ear adhesive tape (6). In the technical scheme, a ball head is arranged on the upper side of the pressing plate, the ball mortar is arranged at the lower end of the screw, and the pressing plate is connected with the screw through the ball head and the ball mortar; and a magnetic needle is arranged in a knob of the screw, and the scales of the knob is indicated by compass property that the magnetic needle does not rotate with the knob, so that defects that a structure is complicated, the cost is high and the pressing plate is in difficult fit with hemostatic positions of wound limbs in the prior art are overcome. In the provided screw type compression hemostat with the universal pressing plate and the magnetic needle indication, the ball head is connected with the ball mortar, so that the pressing plate is in universal fit with the hemostatic positions of the wound limbs; the scales are indicated by utilizing the magnetic needle, so that a scale indicating mechanism is simplified; and the screw type compression hemostat fulfills the aims that the structure is simple, the cost is reduced and the pressing plate is in easy fit with the hemostatic positions of the wound limbs.

Description

technical field [0001] The invention relates to a medical device, in particular to a universal pressure plate and a screw-type compression hemostat indicated by a magnetic needle, which is used for postoperative hemostasis and wound hemostasis. Background technique [0002] Prior art screw arterial compression hemostat, see Figure 8 , consists of a base with a nut, a screw with a knob, a pressure plate, and a hoop tape; in order to indicate the rotation angle of the screw, the center of the screw is made of a hollow tube, and the transparent knob on the top of the screw is provided with a dial, and the upper part of the pressure plate is set It is a rotating shaft cylinder with a pointer on the top of the rotating shaft cylinder. The upper rotating shaft cylinder of the pressure plate slides and fits through the hollow tube in the center of the screw. The pointer on the top of the rotating shaft is located under the transparent knob with a dial on the top of the screw. When ...

AI Technical Summary

Problems solved by technology

The above-mentioned structure is complex and costly, and the pressure plate and the screw rod slide vertically and orthogonally. When pressing to stop bleeding, it is difficult for the pressure plate to fit the complex curved surface of various parts of the human body and not press on the "point". Therefore, the existing technology has complex structures, High cost, problems and deficiencies that the pressure plate is difficult to fit to the hemostasis of the injured limb
