Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a mounting base for a pressure sensor. Background Technology

[0002] Disposable invasive pressure monitoring sensors are used by medical institutions to monitor patients' arterial pressure, central venous pressure, and other pressures. They are typically equipped with various connectors, such as Abbott connectors, UTA connectors, and BD connectors, to meet the needs of various monitors.

[0003] A search revealed a Chinese patent publication number: CN215874635U, which discloses a disposable pressure sensor fixing device. The device is fixed to a fixing plate via a slot, and the fixing plate can install up to three pressure sensors to monitor blood pressure at different locations. A C-clamp is used to fix the fixing plate and the infusion stand with screws. The disposable pressure sensor is fixed in place by the fixing device, which improves the accuracy of invasive pressure monitoring and provides effective basis for medical staff to take the correct treatment plan.

[0004] In the above technical solution, the sensor is fixed in the slot and then the fixing device is fixed to the infusion stand. However, in order to ensure that the measured blood pressure value reflects the patient's true blood pressure, the sensor needs to be fixed in the fourth intercostal space at the mid-axillary line. Fixing the sensor to the infusion stand will reduce the accuracy of the measurement, or fixing it to the patient with tape in a conventional way will reduce the comfort of the tether and the stability of the fixation. Therefore, a pressure sensor fixing base is proposed to solve the above problems. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3This utility model provides an embodiment of a pressure sensor mounting base, including a mounting strap 1. A shoulder strap 2 is fixedly connected to the top of the mounting strap 1. Two sets of shoulder straps 2 are provided, allowing the mounting strap 1 to be worn on a patient. The surface of the shoulder strap 2 has eyelets 6, with several sets of equally spaced eyelets 6 on each set of shoulder straps 2. The length of the shoulder strap 2 can be adjusted by selecting the corresponding eyelet 6 and connecting it to a fixing buckle 5. A fixing buckle 5 is fixedly connected to the surface of the mounting strap 1. A Velcro fastener 3 is fixedly connected to the outer wall of the mounting strap 1. A second Velcro fastener 4 is detachably connected to the Velcro fastener 3. The Velcro fastener 3 and the second Velcro fastener 4 are mutually adhesive, thus securing the mounting strap 1. A fixing ring 7 is fixedly connected to the inner wall of the fixing band 1. An adhesive plate 8 is attached to the inner surface of the fixing band 1. The adhesive plate 8 is curved to facilitate fitting with the patient's mid-axillary line. A fixing seat 10 is fixedly connected to the top of the adhesive plate 8. A groove 13 is opened on the outer wall of the fixing seat 10. A spring 14 is fixedly connected to the inner wall of the groove 13. A clamping plate 15 is fixedly connected to the end of the spring 14. A screw 16 is threadedly connected to the inner wall of the fixing seat 10. A limit plate 18 is rotatably connected to the end of the screw 16. The cooperation between the limit plate 18 and the clamping plate 15 can provide clamping and fixing force for the pressure sensor. A dial ring 17 is fixedly connected to the outer wall of the screw 16. A disassembly assembly is provided on the surface of the fixing seat 10.

[0032] Reference Figures 2-4 A sponge pad 12 is fixedly connected to the outer wall of the bonding plate 8. The sponge pad 12 contacts the patient's mid-axillary line, increasing the patient's comfort when wearing the fixation seat 10. The sponge pad 12 is fixed to the inner side of the bonding plate 8 with nano double-sided adhesive for easy replacement. The side wall of the clamping plate 15 is slidably connected to the inner wall of the groove 13, and the side wall of the limiting plate 18 is slidably connected to the inner wall of the groove 13. The fixation seat 10 is sleeved on the outer wall of the fixation strap 1, and the end of the Velcro strap 2 4 is fixedly connected to the outer wall of the fixation strap 1. The disassembly and assembly components include screw holes 9. The screw hole 9 is located on the outer wall of the bonding plate 8 away from the sponge pad 12. The inner wall of the screw hole 9 is threaded with a fixing bolt 11. The depth of the screw hole 9 is only one-third of the wall thickness of the bonding plate 8. When the fixing bolt 11 is connected to the screw hole 9, it will not pass through the bonding plate 8. The outer wall of the fixing bolt 11 is threaded with the inner wall of the fixing seat 10. When the fixing bolt 11 is screwed into the fixing seat 10 and connected to the screw hole 9, it can pass through the fixing ring 7. The fixing ring 7 is made of hard plastic to prevent the soft material fixing band 1 from wrinkling and causing unstable fixing.

[0033] Reference Figures 3-4The outer wall of the fixed base 10 is provided with an adjustment hole 19. The center point of the adjustment hole 19 is on the same horizontal line as the central axis of the slot 13. The inner wall of the adjustment hole 19 is threaded with a fixing rod 20. The outer wall of the fixing rod 20 is fixedly connected with a mounting plate 21. The outer wall of the mounting plate 21 is fixedly connected with a rubber block 22. The surface of the rubber block 22 is provided with a pipe groove 23. The pipe groove 23 is set in a shape larger than a semicircle. There are two sets of adjustment holes 19, fixing rods 20, mounting plates 21 and rubber blocks 22 respectively, and they are symmetrically arranged with the center point of the fixed base 10 as the axis of symmetry. The pipe grooves 23 on the two sets of rubber blocks 22 can clamp and limit the hose connected to the pressure sensor.

[0034] Working principle: Pass the patient's two arms through the two sets of shoulder straps 2, adjust the length of the shoulder straps 2 to determine the position of the fixing strap 1 on the patient's body, select the corresponding buckle 6 and fasten it on the fixing buckle 5 to fix the shoulder straps 2. Use Velcro 3 and Velcro 4 to fix the fixing strap 1. Place the pressure sensor into the slot 13. At this time, the clamping plate 15 will be compressed by the spring 14. Manually turn the dial ring 17 to drive the screw 16 to rotate a distance from the inner wall of the fixing seat 10. At this time, the limiting plate 18 gradually approaches the pressure sensor and fixes the pressure sensor in conjunction with the clamping plate 15. Insert the two sets of hoses connecting the patient's body and the external monitor into the pipe slot 23. Due to the properties of the rubber material of the rubber block 22, it has deformation and anti-slip capabilities. Furthermore, the pipe groove 23 is larger than a semi-circle, which can provide a limit for the hose. Then, a rotational force is applied to the mounting plate 21, causing it to screw into or out of the adjustment hole 19 by a certain distance, thereby switching the orientation of the rubber block 22. This allows for better connection of the hose to the patient's body and the external monitor. When the patient is lying flat, the pressure sensor is located in the fourth intercostal space at the mid-axillary line, ensuring that the height of the pressure sensor is consistent with the level of the heart, reducing the influence of gravity on the fluid column, and thus obtaining accurate blood pressure measurement values. Finally, the fixing bolt 11 is reversed so that it is disengaged from the screw hole 9 and the fixing ring 7 in sequence. After separating the fixing seat 10 from the fixing strap 1, it is convenient to clean the fixing strap 1 or disinfect the fixing seat 10, improving the ease of use of the fixing seat 10 and the stability of fixing the pressure sensor.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
