Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, and in particular relates to a disposable invasive pressure sensor fixing device. Background Art

[0002] Invasive pressure sensors are mainly used clinically to monitor central venous pressure and arterial pressure. They are mainly used in anesthesiology departments and ICU rooms, and are usually used in conjunction with invasive arterial catheters.

[0003] At present, in clinical use, disposable invasive pressure sensors are mainly fixed to one side of the bed by vertical fixing bars or brackets, or fixed to the patient's limbs by tape winding or tying. These fixing methods mainly have the following shortcomings. First, in the method of fixing with vertical fixing bars or brackets, especially for patients in the ICU intensive care unit, since the height of the sensor needs to be adjusted and fixed according to the patient's body position, whenever the patient lies flat or sits, the position of the sensor needs to be repositioned to ensure that the sensor can maintain the same height as the heart. In actual use, it will greatly increase the workload of medical staff; and in the method of tape winding or tying, the tightness of the binding is difficult to grasp, which depends entirely on the doctor's experience and judgment, and the tightness cannot be adjusted after binding. Once the binding is too tight, the tape can only be removed and re-tied, which is extremely inconvenient to operate.

[0004] To this end, we propose a disposable invasive pressure sensor fixation device that is easy to use. Utility Model Content

[0005] The utility model aims to provide a disposable invasive pressure sensor fixing device to solve the above problems existing in the prior art.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] Furthermore, the base belt is an inelastic webbing with a width of 4-5 cm and a length of 40-50 cm, preferably a nylon webbing or a bamboo fiber webbing.

[0009] Furthermore, the two ear straps are arranged relative to each other, and the directions of the two ear straps are designed to be opposite, and the spacing distance between the two ear straps is adapted to the spacing distance between the hanging rings on both sides of the invasive pressure sensor.

[0024] In order to more clearly illustrate the technical solutions in the embodiments of the utility model or the prior art, the utility model will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the utility model. For ordinary technicians in this field, other drawings can also be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the utility model, but does not constitute a limitation of the utility model.

[0025] When using disposable invasive pressure sensors for ICU intensive care patients, the sensors are fixed outside the bed using traditional brackets or fixing strips. Whenever the patient lies flat or sits, the position of the sensor needs to be repositioned to ensure that the sensor is at the same height as the heart. In clinical applications, this greatly increases the workload of medical staff. To solve this problem, we propose an adjustable strap with Velcro to effectively fix the invasive pressure sensor to the patient's limbs (arms) (it can also be fixed to the patient's legs during surgery according to actual needs). The position only needs to be calibrated once when the sensor is fixed, so that the height between the sensor and the heart can be kept relatively flat whether the patient is lying flat or sitting or resting, without the need to frequently adjust the sensor position. The specific solution is as follows:

[0026] Embodiment 1:

[0027] like Figure 1-6As shown, the present embodiment provides a disposable invasive pressure sensor fixing device, specifically comprising a base band 1, the upper surface of one end of the base band 1 is sewn with a magic adhesive fleece surface A2 and a magic adhesive hook surface A3, respectively, the magic adhesive hook surface A3 is located at the end of the base band 1, and a rotatable buckle 7 is installed at the other end of the base band 1, and a pair of ear straps 4 are sewn on the surface of the magic adhesive fleece surface A2 close to the buckle 7, the buckle 7 is a rectangular frame design, a magic adhesive hook surface B5 is sewn on half of the upper surface of the ear strap 4, and a magic adhesive fleece surface B6 is sewn on the other half of the ear strap 4.

[0028] When using the strap to fix the invasive pressure sensor, the strap can be first tied to the patient's limb through the cooperation of the magic adhesive fleece surface A2 and the magic adhesive hook surface A3 on the base band 1, and then with the help of the design of the buckle 7, the invasive pressure sensor can be fixed to the strap through the cooperation of the hanging rings on both sides of the strap and the two ear straps 4. At the same time, medical staff can also fix the invasive pressure sensor to the strap first and then tie the strap to the patient's limb according to needs.

[0029] In order to improve the comfort of the straps when binding, the contact area between the limbs and the straps is increased to reduce the tightness during binding. The base belt 1 is an inelastic webbing with a width of 4-5 cm and a length of 40-50 cm, and preferably a nylon webbing or a bamboo fiber webbing. The use of an inelastic webbing as the base belt 1 of the straps can effectively avoid the problem of increasing the difficulty of controlling the tightness during the binding operation due to the elastic effect of the fabric itself, and the inelastic webbing design has strong deformation resistance. When binding, the force on the side of the webbing in contact with the limbs is more uniform than that of the elastic webbing.

[0030] In order to smoothly fix the invasive pressure sensor, the two ear straps 4 are arranged relative to each other, and the directions of the two ear straps 4 are designed to be opposite. The interval between the two ear straps 4 is adapted to the distance between the hanging rings on both sides of the invasive pressure sensor. When fixing the invasive pressure sensor, one end of the two ear straps 4 is passed through the corresponding hanging rings on both sides of the invasive pressure sensor and then the ear straps 4 are flipped over so that the magic adhesive surface B6 and the magic adhesive hook surface B5 on the ear straps 4 are bonded to each other, and the invasive pressure sensor is firmly fixed on the surface of the magic adhesive surface A2.

[0031] In order to further improve the comfort of the fixing device, a skin-friendly layer is sewn at the bottom of the base band 1. The thickness of the skin-friendly layer is preferably 1-1.5 mm, and the skin-friendly layer can be made of sterile, soft, sweat-absorbent and breathable fabric, preferably pure cotton fabric.

[0032] Embodiment 2:

[0033] Since invasive pressure sensors are mainly used to monitor central venous pressure and arterial pressure, in the process of fixing the sensor, once the binding force is too large (i.e., too tight), it will affect the accuracy of the final test results. In traditional binding operations, since each patient has different perceptions, it is often inaccurate to judge the tightness of the binding by asking the patient, especially in some clinical operations where the patient is in anesthesia and coma, it is even more difficult to get an answer by asking. Therefore, when binding and fixing invasive pressure sensors, medical staff basically make judgments based on experience. However, this method of using experience judgment has high practical requirements and experience for medical staff. For some medical staff who are in the stage of accumulating experience, it is easy to have the problem of rework and rebinding, which is time-consuming and laborious. Moreover, even experienced medical staff find it difficult to accurately grasp the binding force. For this reason, we need to visually design the binding force so that medical staff can accurately control the binding force. The specific plan is as follows:

[0034] like Figure 1-6 As shown, this embodiment is different from the first embodiment in that, based on the scheme recorded in the first embodiment, this embodiment also includes a binding pressure monitoring component, wherein the binding pressure monitoring component includes a strip-shaped flexible pressure sensor 8, a plug connector 9 and a micro-electronic display 11, the strip-shaped flexible pressure sensor 8 is electrically connected to the plug connector 9 through a wire, and the micro-electronic display 11 is electrically connected to the plug connector 9 through a plug terminal. Specifically, the plug connector 9 is fixedly mounted on one end of the magic adhesive surface A2, and the micro-electronic display 11 is slidably plugged between two card slots 10 fixed on the magic adhesive surface A2, and the strip-shaped flexible pressure sensor 8 is located in the gap between the skin-friendly layer and the base band 1, and the pressure sensing contacts on the strip-shaped flexible pressure sensor 8 are all arranged toward the skin-friendly layer side.

[0035] A storage battery and a display module for displaying pressure values ​​are also provided inside the micro electronic display 11 . When the storage battery is electrically connected to the plug connector 9 through the micro electronic display 11 , it simultaneously supplies power to the strip-shaped flexible pressure sensor 8 .

[0036] In this embodiment, the micro electronic display 11 adopts a small liquid crystal display device which is more common in current electronic products. It is a well-known technology in the field of electronic product technology, so it is not described in detail in the above text. Among them, the micro electronic display 11 adopts a detachable connection of sliding plug, which can make one micro electronic display 11 adapt to multiple fixing devices of the same type, so that medical staff only need to carry one display device when performing invasive pressure sensor fixing operations on patients in multiple I CU rooms one after another. Secondly, a strip-shaped flexible pressure sensor 8 is adopted, and the pressure sensing contact on it is arranged toward the side of the skin-friendly layer. On the one hand, the flexible characteristics of the strip-shaped flexible pressure sensor 8 itself will not affect the bending and binding operation of the baseband 1. Secondly, the points for binding pressure detection can be evenly distributed on the bottom surface of the baseband 1. During the binding operation, the binding pressure values ​​of multiple points can be measured. With the average value as a reference, the accuracy of binding pressure detection can be greatly improved. Moreover, the value detected by the strip-shaped flexible pressure sensor 8 is finally transmitted to the micro electronic display 11 through the wire via the plug connector 9 and is intuitively displayed in digital form, which provides convenience for medical staff to accurately control the binding force.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
