Abstract
Description
Technical Field
[0001] The invention relates to the technical field of medical devices, in particular to a limb restraint for nursing patients in an operating room. Background Art
[0002] During surgery, in order to ensure the safety of the patient and the smooth progress of the operation, it is often necessary to properly restrain the patient's limbs. As an important surgical auxiliary tool, the main function of the limb restraint is to fix the patient's limbs and prevent the patient from unconsciously moving due to pain, anxiety or other reasons, thereby avoiding adverse effects on the patient or the surgical operation.
[0003] At present, the commonly used limb restraint methods in the operating room mainly include strap fixation and simple clamp restraint. Strap fixation is the most traditional method, which is achieved by wrapping the strap around the patient's limbs and tightening them. However, this method has many problems: first, the tightness of the strap is difficult to control accurately. If it is too tight, it may cause obstruction of blood circulation in the patient's limbs, causing local ischemia or even tissue damage; if it is too loose, it cannot effectively restrain the patient, and there is a risk of the patient breaking free. Secondly, the strap lacks a buffering function when the patient struggles, and it is easy to cause compressive damage to the patient's limbs. In addition, the fixing and adjustment process of the strap is relatively cumbersome, requiring medical staff to spend more time and energy to adjust it, which reduces the work efficiency of the operating room. Although the simple clamp restraint solves the shortcomings of the strap to a certain extent, its structure is relatively simple and its function is relatively single. It is impossible to flexibly adjust the restraint strength and position according to the different conditions of the patient, and it also lacks an effective buffering and protection mechanism when the patient struggles. Therefore, the existing limb restraints still need to be improved in terms of safety, comfort and ease of operation. The development of a limb restraint for nursing patients in the operating room that can effectively solve these problems has important clinical application value. Summary of the invention

[0012] Preferably, a limit handle is rotatably arranged in the middle position inside one side of the limit slide, a limit block is fixedly arranged on one side of the limit handle, a plurality of limit columns are fixedly arranged at the lower end of the limit plate, a plurality of limit holes are opened at the upper end of the limit slide frame, and a plurality of the limit columns are clamped into some of the plurality of limit holes.
[0013] Preferably, the connecting mechanism includes a support frame, a soft pad is fixedly arranged inside the support frame, two connecting grooves are provided on both sides of the support frame, two installation grooves are provided on both sides of the support frame near the middle position, and four constraint mechanisms are provided, and the four constraint mechanisms are respectively arranged inside the four installation grooves.
[0014] Preferably, a retractable card block is embedded and slidably provided on one side of the interior of the multiple installation grooves, and the multiple retractable card blocks are connected to the interior of the support frame through springs, and multiple internal support springs are embedded and provided on the other side of the interior of the multiple installation grooves, and a movable plate is fixedly provided on the other end of multiple groups of internal support springs, and a sliding card block is fixedly provided on the other end of the movable plate, and support strips are fixedly provided on both sides of the interior of the multiple installation grooves near the lower end.
[0015] Preferably, a limiting structure is slidably penetrated at the lower end of one of the two rotating shafts, and a trigger rod is provided at the upper end of the limiting structure. The upper end of the trigger rod penetrates the upper end of the limiting frame, and the trigger rod is used to drive the limiting structure to descend to cancel the limitation on the rotating shaft.
[0016] Working principle: The working process of this operating room patient care limb restraint is as follows: First, press the trigger rod, and the trigger rod drives the limit structure to descend, thereby canceling the limit on the rotating shaft. At this time, pull the adjustment handle, and the adjustment handle drives the adjustment slide frame to move in the limit frame through the transmission action of the transmission belt. Next, turn the limit handle, and the limit handle drives the limit block to rotate, so that the limit block cancels the limit on the limit slide. After that, pull the limit plate upward, and the limit plate drives the limit column to rise, and the limit slide can slide freely at this time. After sliding to the appropriate designated position, lower the limit plate so that the limit column is stuck in the limit hole, and then turn the limit handle again to drive the limit block to be stuck inside the limit slide, so as to limit the limit slide, and then adjust the upper limit frame and the lower limit frame to the ideal position;
[0017] After completing the above adjustments, open the fixing buckle and flip open the upper limit frame, place the patient's limbs between the upper limit frame and the lower limit frame, and then fasten the fixing buckle to restrain the patient's limbs. During the patient's operation, if the patient struggles, the soft properties of the sponge pad and the restraint airbag can prevent the patient's limbs from being injured. At the same time, the patient's struggle will drive the adjustment slide frame to move, and the buffer spring will deform to absorb the impact force. In addition, the movement of the adjustment slide frame will squeeze the sealing cylinder, which inhales air from the outside through the one-way valve, and then fills the gas into the restraint airbag through the inflation tube, causing the restraint airbag to expand, further strengthening the restraint of the patient's limbs.
[0018] (III) Beneficial effects
[0019] The present invention provides a limb restraint for nursing patients in an operating room. It has the following beneficial effects:
[0020] 1. The present invention provides a limb restraint for nursing patients in an operating room. The restraint mechanism of the limb restraint is provided with an adjustment handle, a transmission belt and an adjustment slide frame assembly that cooperate with each other to form a precise adjustment system. Medical staff only need to gently pull the adjustment handle, and with the help of the transmission effect of the transmission belt, they can easily drive the adjustment slide frame to move smoothly in the limit frame. This process can accurately adjust the upper limit frame and the lower limit frame to the most suitable position according to individual differences such as the thickness, length and placement of the patient's limbs. During the period when the patient's limbs are restrained, the sponge pad inside the upper limit frame is soft and elastic, and can evenly disperse the pressure; the restraint airbag inside the lower limit frame can be adaptively adjusted according to the contour of the patient's limbs. The two work together to effectively fit the patient's limbs, greatly improving the patient's comfort during the operation, and fundamentally avoiding potential injuries such as crushing and abrasions to the patient's limbs caused by hard constraints.
[0021] 2. The present invention provides a limb restraint for nursing patients in an operating room. When the patient struggles during the operation, the buffering and intelligent restraint enhancement mechanism of the device is quickly activated. The movement of the adjusting slide frame will cause the buffer spring to deform, which can quickly and effectively absorb the impact force generated by the patient's struggle, play an excellent buffering effect, and prevent the patient's limbs from being injured due to violent shaking. At the same time, the movement of the adjusting slide frame will also produce continuous squeezing on the sealing cylinder, causing it to continuously perform reciprocating motions of elongation and shortening. In this process, the sealing cylinder inhales air from the outside through a one-way valve. The setting of the one-way valve ensures that the gas can only flow in one direction, avoiding gas backflow. The inhaled air is accurately delivered to the restraint airbag through the inflation tube, causing the restraint airbag to gradually expand. As the restraint airbag expands, the restraint force on the patient's limbs is automatically enhanced, and this enhancement changes dynamically according to the degree of the patient's struggle, effectively preventing the patient from breaking free, and providing a solid guarantee for the safe conduct of the operation.
