Description

Technical Field

[0001] This utility model relates to nursing equipment, and more particularly to a precise pressure control and timing compression device for wounds after pacemaker implantation. Background Technology

[0002] For patients who have undergone traditional permanent pacemaker implantation, intermittent compression of the wound area is necessary in clinical nursing care to prevent bleeding and subcutaneous hematoma at the implantation site.

[0003] Current techniques involve applying pressure to the wound using saline bags. However, different patients require different weights of saline bags, and repeatedly adjusting the weight increases the complexity of nursing care. If a hematoma develops in the wound area, an ice pack needs to be used for low-temperature compression, requiring the replacement of the saline bag with an ice pack or the simultaneous use of both, further increasing the workload. Furthermore, during compression, the saline or ice pack is difficult to secure, often slipping and deviating from its compression position, affecting the effectiveness of the compression. To prevent patient discomfort or tissue necrosis caused by prolonged compression, intermittent compression is necessary; however, manual timed decompression is inaccurate and cumbersome. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a precise pressure adjustment and timing compression device for the wound after pacemaker implantation. It can not only quickly switch between normal temperature compression and low temperature compression of the wound position as needed, but also provides a precise control scheme for compression intensity and time interval compression. It is easy to position, does not slip, and provides convenience for postoperative care.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a precise pressure adjustment and timing compression device for post-pacemaker implantation wounds, comprising a counterweight base with rollers, a column vertically mounted on the counterweight base, a horizontally extending cantilever connected to the top of the column, a cold water tank connected to the column, an electric telescopic rod connected to the end of the cantilever, and a compression device connected to the lower end of the electric telescopic rod; the compression device comprises a pressure plate rotatably connected to the electric telescopic rod via a ball joint hinge, a salt cylinder threadedly connected to the bottom of the pressure plate, and two layers of water-resistant membranes stretched at the lower end of the salt cylinder, a pressure sensor being installed on the lower surface of the lower water-resistant membrane, and the two ends of the two water-resistant membranes being connected to the cold water tank via a water supply pipe and a water return pipe, respectively, and the cold water tank being equipped with a water pump.

[0006] Furthermore, the interlayer between the two waterproof membranes is filled with a loose, porous, and hydrophobic filler.

[0007] Furthermore, the filler is in the form of fine granules or a mesh.

[0008] Furthermore, the drive motor of the electric telescopic pole is equipped with a control panel, which includes a timer button and a pressure adjustment knob. The pressure sensor is connected to the drive motor via a signal line.

[0009] Furthermore, the cold water tank is connected to the column via a sliding frame.

[0010] Furthermore, the column and the cantilever bracket are provided with reinforcing rods at an angle.

[0011] Furthermore, the salt cylinder is filled with salt bags or loose salt granules.

[0012] Furthermore, the outer circumferential surface of the pressure plate and the inner wall of the salt cylinder are provided with matching threads.

[0013] The beneficial effects of adopting the above technical solution are as follows: This utility model provides downward pressure through an electric telescopic rod; the interlayer between the cold water tank, water supply pipe, and water-resistant membrane, and the return water pipe form a closed channel for the refrigerant; the pump controls whether to pump low-temperature water into the interlayer of the water-resistant membrane; the control panel sets the downward pressure and compression duration, and the pressure sensor detects the actual compression force, allowing for fine-tuning of the compression force based on the patient's sensation; the ball joint hinge allows the compressor to adaptively adjust its angle according to the external contour of the patient's body; it not only allows for quick switching between normal temperature compression and low temperature compression of the wound location as needed, but also provides a precise control scheme for compression force and timed interval compression, is easy to position, does not slip, and provides convenience for postoperative care.

[0018] See appendix Figure 1 and 2In one specific embodiment of this utility model, the structure includes a counterweight base with rollers, a vertically mounted column on the counterweight base, a horizontally extending cantilever rod connected to the top of the column, a cold water tank connected to the column, and an electric telescopic rod connected to the end of the cantilever rod. The lower end of the electric telescopic rod is connected to a compressor. The compressor includes a pressure plate rotatably connected to the electric telescopic rod via a ball-joint hinge, a salt cylinder threaded below the pressure plate, and two layers of waterproof membranes stretched over the lower end of the salt cylinder. A pressure sensor is installed on the lower surface of the lower waterproof membrane. The two ends of the two waterproof membranes are connected to the cold water tank via a water supply pipe and a return pipe, respectively. The cold water tank is equipped with a water pump. The counterweight base ensures the stability of the compressor and prevents it from tipping over.

[0019] The interlayer between the two waterproof membranes is filled with a loose, porous, and hydrophobic filler. The filler is in the form of fine granules or a mesh. The filler supports the two waterproof membranes, preventing them from sticking together under pressure and blocking cold water from passing through.

[0020] The drive motor of the electric telescopic rod is equipped with a control panel, which features a timer button and a pressure adjustment knob. A pressure sensor is connected to the drive motor via a signal cable. The control panel allows setting the compression pressure and duration, while the pressure sensor detects the actual compression force, allowing for fine-tuning of the pressure based on the patient's sensations.

[0021] The cold water tank is connected to the column via a sliding bracket. The sliding bracket allows for adjustment of the cold water tank's height; it is recommended to adjust it so that the cold water tank and the compressor are at the same horizontal level to reduce the height difference of the pumped liquid and decrease energy consumption.

[0022] The uprights and the cantilever support are reinforced with reinforcing bars at an angle. These reinforcing bars improve the stability of the cantilever.

[0023] The salt cylinder is filled with salt bags or loose salt granules.

[0024] The outer circumferential surface of the pressure plate and the inner wall of the salt cylinder are provided with matching threads.

[0025] The working principle of this invention is as follows: During use, a salt bag is placed inside a salt cylinder, which is then threaded onto the pressure plate. After tightening, the lower surface of the pressure plate compacts the salt bag or loose salt particles inside the cylinder. The rollers move the compressor, adjusting it above the pacemaker implantation site. The pressure and duration are adjusted via the control panel. The drive motor extends the electric telescopic rod, pressing the lower surface of the compressor's waterproof membrane against the patient's wound area. Thanks to the adaptive angle adjustment of the ball joint hinge, the compressor automatically adjusts to fit the patient's body, preventing discomfort caused by misalignment. When low-temperature compression is required, a water pump is activated, pumping cold water from the tank into the membrane's interlayer to provide low-temperature compression to the wound area and relieve hematoma. A pressure sensor provides real-time pressure feedback. A timer button connects to a timer module, which automatically keeps track of the compression duration. Once the required duration is reached, the timer module sends a signal to the drive motor, causing it to reverse, shorten the electric telescopic rod, and stop the compression. The compression cycle then resumes, repeating this process to complete the timed interval compression program.

[0026] The above description is only presented as a feasible technical solution of this utility model and is not intended as a single limitation on the technical solution itself.
