DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Please refer to Figures 1-4, An invasive blood pressure monitoring device with a limiting structure, including a device fixing plate 1.

The mutually adjacent side surfaces of the connecting fixing belt 4 are adhered to each other. Inside the connecting fixing belt 4, a monitoring head 5 of the invasive blood pressure monitoring device is clamped. The monitoring head 5 of the invasive blood pressure monitoring device is a monitoring structure containing parts such as a pressure sensor and is the main component of the invasive blood pressure monitoring device. By using the connecting fixing belt 4, the monitoring head 5 of the invasive blood pressure monitoring device can be installed at the required position on the patient's body surface, so as to accurately monitor the patient's blood pressure using the invasive blood pressure monitoring device;

[0023] The body surface fixing mechanism 2 includes a winding box 201. The bottom surface of the winding box 201 is fixedly connected to the upper surface of the device fixing plate 1. Connecting wires 6 are fixedly communicated with both side surfaces of the monitoring head 5 of the invasive blood pressure monitoring device. On the upper surface of the device fixing plate 1, an auxiliary fixing belt 3 is fixedly connected. By using the connecting wires 6, the monitoring head 5 of the invasive blood pressure monitoring device can be connected and used with the invasive blood pressure monitoring device. By using the auxiliary fixing belt 3, it is convenient to assist in fixing the monitoring head 5 of the invasive blood pressure monitoring device.

[0024] Inside the winding box 201, a winding bolt 202 is rotatably connected. A fastening nut 208 is threadedly connected to the outer surface of the winding bolt 202. One end of the winding bolt 202 away from the fastening nut 208 is fixedly connected to a torsion buckle 7. Two buffer rings 8 are sleeved on the outer surface of the winding bolt 202. The inner wall of one of the buffer rings 8 is fixedly connected to the outer surface of the winding bolt 202, and the back surface of the other buffer ring 8 is in contact with the front surface of the fastening nut 208. By manually pinching the torsion buckle 7, it is convenient to rotate the winding bolt 202. And by sleeving two buffer rings 8 on its surface, when the winding bolt 202 is tightened, the pressure exerted by the winding bolt 202 on the winding box 201 can be buffered.

[0025] A fixing elastic band 203 is sleeved on the outer surface of the winding bolt 202. The fixing elastic band 203 is made of soft rubber band material and is an elastic band with a certain elasticity. One end of the fixing elastic band 203 far away from the winding box 201 penetrates through the winding box 201 and extends to the left side of the winding box 201. A connecting block 204 is fixedly connected to the end of the fixing elastic band 203 far away from the winding box 201. A fixing block 205 is fixedly connected to the upper surface of the equipment fixing plate 1. The left side surface of the connecting block 204 is in contact with the right side surface of the fixing block 205. An L-shaped clamping groove 206 is opened on the right side surface of the fixing block 205. A wedge-shaped clamping buckle 207 is fixedly connected to the left side surface of the connecting block 204. The wedge-shaped clamping buckle 207 is clamped inside the L-shaped clamping groove 206. A disassembly box 9 is fixedly connected to the upper surface of the fixing block 205. The disassembly box 9 is communicated with the L-shaped clamping groove 206. By fixedly connecting the disassembly box 9 to the upper surface of the fixing block 205, it is convenient to arrange the disassembly mechanism inside the disassembly box 9, so as to facilitate the disassembly of the wedge-shaped clamping buckle 207 from the inside of the L-shaped clamping groove 206.

[0026] A disassembly rod 10 is slidably connected inside the disassembly box 9. An extrusion plate 14 is fixedly connected to the bottom end of the disassembly rod 10. The extrusion plate 14 is slidably connected inside the L-shaped clamping groove 206. By manually pressing the disassembly rod 10, it can slide inside the disassembly box 9, so as to use the extrusion plate 14 to extrude the wedge-shaped clamping buckle 207 inside the L-shaped clamping groove 206, and further facilitate the disassembly of the wedge-shaped clamping buckle 207 from the inside of the L-shaped clamping groove 206.

[0027] A sliding plate 11 is fixedly connected to the outer surface of the disassembly rod 10. The sliding plate 11 is slidably connected inside the disassembly box 9. An extrusion spring 12 is fixedly connected to the bottom surface of the sliding plate 11. The bottom end of the extrusion spring 12 is fixedly connected to a sliding ring 13. The inner walls of the extrusion spring 12 and the sliding ring 13 are both in contact with the outer surface of the disassembly rod 10. The bottom surface of the sliding ring 13 is in contact with the upper surface of the fixing block 205. By sliding the disassembly rod 10 inside the disassembly box 9, the sliding plate 11 can be used to squeeze the extrusion spring 12 to accumulate elastic force inside it, so as to use this elastic force to make the used disassembly rod 10 bounce back to its original state, and further facilitate the reuse of this disassembly structure.

[0028] The working principle of the present utility model is as follows: When in use, first connect the monitoring head 5 of the invasive blood pressure monitoring device to the medical monitor through the connecting wire 6. When it is necessary to use the invasive blood pressure monitoring device with a limiting structure to perform real-time, continuous, dynamic and accurate blood pressure monitoring on a patient, first manually place the device fixing plate 1 at the body surface position of the cardiac zero point where the monitoring head 5 of the invasive blood pressure monitoring device needs to be placed. Then, manually control the winding bolt 202 to twist the fastening nut 208, so that the winding bolt 202 can rotate in the winding box 201. Since the fixing elastic band 203 is wound around the outer surface of the winding bolt 202, by rotating the winding bolt 202, the fixing elastic band 203 can be loosened from its surface, and thus the fixing elastic band 203 can be extended, which is convenient for medical staff to pass the fixing elastic band 203 through the patient's waist until one end of the fixing elastic band 203, the fixed connecting block 204, contacts the fixed block 205;

[0029] At this time, by twisting the winding bolt 202, after the fixing elastic band 203 is wound to an appropriate length, manually twist the fastening nut 208 until the two buffer rings 8 tightly contact both sides of the winding box 201, so that the extended length of the fixing elastic band 203 can be fixed. When the connecting block 204 contacts the fixed block 205, the wedge-shaped buckle 207 fixed on one side of the connecting block 204 can be snapped into the internal L-shaped card slot 206, so that both ends of the fixing elastic band 203 are fixed to both sides of the device fixing plate 1. Since the fixing elastic band 203 is made of soft rubber band material and has a certain elasticity, the device fixing plate 1 can be stably set at the required position;

[0030] Then, manually install the monitoring head 5 of the invasive blood pressure monitoring device into the connecting and fixing band 4, and use the magic tape fixed in the connecting and fixing band 4 to fix the monitoring head 5 of the invasive blood pressure monitoring device, so that the invasive blood pressure monitoring device with a limiting structure can be used safely and stably to perform real-time, continuous, dynamic and accurate blood pressure monitoring on the patient. When it is necessary to disassemble this structure, only need to manually press the disassembly rod 10 in the disassembly box 9, and the extrusion plate 14 at the bottom end of the disassembly rod 10 can be used to squeeze the wedge-shaped buckle 207 in the L-shaped card slot 206, so that the wedge-shaped buckle 207 can be conveniently pulled out of the L-shaped card slot 206 to complete the disassembly of this structure.

[0031] The above is only the preferred specific implementation mode of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its utility model concept, making equivalent replacements or changes should be covered within the protection scope of the present utility model.
