Problems solved by technology

In the nursing operation of LMWH injection, medical staff still generally use direct injection, relying on memory and experience to select the injection site. However, LMWH is different from other injections. Its drug characteristics make multiple injections at close distances cause petechiae on the skin surface , ecchymosis, if the injection operation is continued without treatment, it will lead to adverse reactions such as hematoma, tissue necrosis, epidermal hemorrhage, etc., which will be life-threatening in severe cases
Although when epidermis symptoms appear, this situation will generally be noticed by medical staff, who will change the injection site, or use the positioning card for injection in the prior art, but it is still difficult to avoid epidermal congestion and redness when the hospital students and patients operate on their own The phenomenon of pain not only increases the probability of adverse reactions, but also increases the suffering of patients
Even if the existing injection cards are used in this LMWH injection, there are still defects. Because of the wide range of injection drugs used, the technical purpose is to avoid repeated injections at the same needle hole position, and the distance selection is mostly limited to greater than 5mm. Therefore, our hospital introduced it to China. Patent 201520987340.8 heparin injection positioning card, Chinese patent application number 201520718596.9 interferon injection positioning plate, Chinese patent 201120134476.6 insulin injection positioning device and other specific drug injection positioning devices, but the effect is not ideal no matter whether the positioning distance is greater than or less than 20mm. According to the statistical results of clinical trials, the effect of using the universal injection card is not ideal, and cases of ecchymosis, subcutaneous nodules, redness, swelling and bleeding, skin hematoma, purple black and even skin necrosis have occurred

Embodiment Construction

[0016] Such as figure 1 , 2 As shown, the scale disc for nursing operation of low molecular weight heparin injection includes a main disc body 1 and a pair of wings 2, wherein the main disc body 1 includes a positioning disc 3, an inner peripheral rail 4, an outer peripheral rail 5, a scale fan disc 6, and a pointer The positioning rod 7 and the concentric positioning rod 8, the inner peripheral rail 4 is arranged on the outer edge of the positioning plate 3, the scale fan plate 6 is slidingly fitted between the inner peripheral rail 4 and the outer peripheral rail 5, and the travel watch double wings 2 Slidingly fitted on the outer peripheral rail 5 of the main disc body 1 . One end of the pointer positioning rod 7 is rotatably connected to the center of the positioning plate 3, and the concentric positioning rod 8 is magnetically slipped on the pointer positioning rod 7. Both the pointer positioning rod 7 and the concentric positioning rod 8 are provided with a number of in...

Abstract

The invention relates to a scale disk for nursing operation of low-molecular weight heparin injection. The scale disk comprises a main disk body and meter moving double wings. The main disk body comprises a positioning disk, an inner circumferential rail, an outer circumferential rail, a scale sector plate, a pointer positioning rod, and a concentric positioning rod. The inner circumferential rail is arranged on the outer edge of the positioning disk. The scale sector plate is slidably configured between the inner circumferential rail and the outer circumferential rail. The meter moving double wings are slidably configured on the outer circumferential rail of the main disk body. Aimed at injection medicine characteristics of low-molecular weight heparin, horizontal, longitudinal, and circumferential distances of an injection position are accurately controlled around 20 mm. through the positioning disk, an injection range is positioned, a central positioning plate aligns at a basic injection point, an injection forbidden annular plate shields an injection forbidden region, the pointer positioning rod positions angles and longitudinal interval, and the concentric positioning rod positions distance and horizontal interval. After positioning holes of the two positioning rods are overlapped, a position most suitable for injection is accurately founded, so operation of a nurse is more accurate and rapid, and difficulty of self-operation of an intern doctor and a patient is effectively reduced.

Description

technical field [0001] The invention relates to a medical device, in particular to a scale disc for nursing operation of low molecular weight heparin injection. Background technique [0002] Low-molecular-weight heparin (LMWH) is mainly used in the prevention and treatment of thromboembolic diseases clinically, because it is less likely to bleed and has high bioavailability when exerting antithrombotic effects, so drugs with similar effects are more clinically used. widely. In the nursing operation of LMWH injection, medical staff still generally use direct injection, relying on memory and experience to select the injection site. However, LMWH is different from other injections. Its drug characteristics make multiple injections at close distances cause petechiae on the skin surface , ecchymosis, if the injection operation is continued without treatment, it will lead to adverse reactions such as hematoma, tissue necrosis, epidermal hemorrhage, etc., which may be life-threate...
