[0001] The utility model relates to medical instrument technical field, concretely is a portable arterial pressure monitoring sensor fixing device. BACKGROUND

[0002] In clinical critical care, invasive arterial pressure monitoring is an important indicator reflecting the patient's hemodynamic state. The traditional tape fixing pressure group is usually used, which has the following defects: 1. Body position interference: when the patient sits up to eat or carries out rehabilitation training, the traditional fixing device is difficult to keep the sensor consistent with the heart level with the change of body position, resulting in distortion of the pressure measurement value (normal error can reach 10-15mmHg), and often accompanied by changes in illness during activity, nurses need to observe in time to prevent adverse events; 2. Fixation defects: conventional adhesive tape fixation is easily affected by patient activity and displacement, nurses need to adjust frequently, and need to be zeroed in time after position change, increasing the workload; 3. Skin damage: long-term contact with hard fixing materials can cause pressure damage; 4. Inconvenient operation: the existing fixing frame lacks a quick disassembly and assembly structure, affecting the nursing operation efficiency. SUMMARY

[0003] In view of the defects of the prior art, the utility model provides a portable arterial pressure monitoring sensor fixing device, which solves the above problems.

[0004] To achieve the above purpose, the utility model realizes the following technical scheme: a portable arterial pressure monitoring sensor fixing device, comprising:

[0005] Flexible base layer, as the installation basis of arterial pressure monitoring sensor, placed flat or rolled and bound on the upper arm to keep the arterial pressure monitoring sensor and the ventricle level;

[0006] Mounting seat, fixedly connected to the top center of the flexible base layer;

[0007] Variable direction mounting piece, rotationally connected to the mounting seat, used for installing the arterial pressure monitoring sensor.

[0008] Preferably, the flexible base layer comprises a memory metal sheet in the inside and a medical silica gel film coated outside, the outer surface of the medical silica gel film is coated with an antibacterial coating, and the bottom of the medical silica gel film is pasted with breathable cotton cloth.

[0009] Preferably, the variable direction mounting piece is composed of a fixing sleeve and a clamping sleeve, and the arterial pressure monitoring sensor is installed on the clamping sleeve.

[0010] Preferably, the clamping sleeve is installed on the fixing sleeve by plug-in connection, or the clamping sleeve is separated from the fixing sleeve and plug-in connected to the clothing chest pocket.

[0011] Preferably, the locking sleeve includes an elastic U-shaped sleeve, with the top two ends of the U-shaped sleeve bent inward to prevent the arterial pressure monitoring sensor from falling off. The rear side of the U-shaped sleeve is provided with an insert, and the locking sleeve is inserted into a fixed sleeve or the chest pocket of clothing through the gap between the insert and the U-shaped sleeve.

[0012] Preferably, the inner surface of the U-shaped sleeve is covered with an anti-slip pad, and the inner surface of the anti-slip pad is provided with anti-slip textures or anti-slip bumps.

[0013] This invention provides a portable arterial pressure monitoring sensor fixation device. Compared with the prior art, it has the following advantages:

[0014] 1. This portable arterial pressure monitoring sensor fixation device allows the sensor to be positioned horizontally at heart level when the patient is resting in bed. When the patient changes position, needs to eat, or undergoes bedside rehabilitation training, the device can be attached directly to the patient's arm like a "snap ring" to maintain the heart-level position for accurate blood pressure measurement. This allows nurses to monitor blood pressure changes during patient activity and promptly correct and prevent adverse events. The flexible substrate layer consists of a medical-grade silicone film encasing a memory metal sheet, coated with an antibacterial layer to ensure antibacterial efficacy. The side in contact with the skin is made of breathable cotton fabric to prevent skin damage.

[0015] 2. This portable arterial pressure monitoring sensor fixing device features a directional mounting component that can rotate to adjust the angle. Regardless of the mounting method, the arterial pressure monitoring sensor automatically rotates to adapt to changing directions, preventing strain on the infusion tubing. Furthermore, the locking sleeve offers two mounting options and its detachable nature allows the arterial pressure monitoring sensor to be installed on a flexible substrate. When the upper arm requires movement, the sensor can also be mounted in a chest pocket of clothing, making it convenient to use. Attached Figure Description

[0025] 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.

[0026] See Figures 1-5 This utility model provides the following two technical solutions:

[0027] First embodiment: A portable arterial pressure monitoring sensor fixation device, comprising:

[0028] The flexible substrate layer 1 serves as the mounting base for the arterial pressure monitoring sensor 2. It can be laid flat or rolled up and tied to the upper arm to keep the arterial pressure monitoring sensor 2 at the same height as the ventricle. The flexible substrate layer 1 includes an internal shape memory metal sheet 11 and an external medical silicone membrane 12. The outer surface of the medical silicone membrane 12 is coated with an antibacterial coating, and a breathable cotton cloth 13 is attached to the bottom of the medical silicone membrane 12.

[0029] Mounting base 3 is fixedly connected to the top center of flexible substrate layer 1;

[0030] The rotatable mounting component 4 is rotatably connected to the mounting base 3 and is used to mount the arterial pressure monitoring sensor 2.

[0031] When the patient is resting in bed, the arterial pressure monitoring sensor 2 will be fixed in a position at the level of the patient's heart. When the patient changes position, needs to eat, or undergoes bedside rehabilitation training, the device can be directly attached to the patient's arm like a "slap ring" to maintain the position at the level of the heart for accurate blood pressure measurement. This allows nurses to observe changes in blood pressure during the patient's activities and correct and prevent adverse events in a timely manner. The flexible substrate layer 1 is made of medical silicone film 12 wrapped with memory metal sheet 11 and coated with antibacterial coating to ensure antibacterial effect. The side in contact with the skin is made of breathable cotton cloth 13 to prevent skin damage to the patient.

[0032] The second embodiment differs from the first embodiment in that the variable mounting component 4 consists of two parts: a fixed sleeve 41 and a snap-fit ​​sleeve 42. The arterial pressure monitoring sensor 2 is mounted on the snap-fit ​​sleeve 42. The snap-fit ​​sleeve 42 is installed on the fixed sleeve 41 by plugging in, or the snap-fit ​​sleeve 42 is detached from the fixed sleeve 41 and inserted into the chest pocket of clothing.

[0033] The snap-fit ​​sleeve 42 includes an elastic U-shaped sleeve 421, with the top two ends of the U-shaped sleeve 421 bent inward to prevent the arterial pressure monitoring sensor 2 from falling off. An insert 422 is provided on the rear side of the U-shaped sleeve 421. The snap-fit ​​sleeve 42 is inserted into the fixing sleeve 41 or the chest pocket of clothing through the gap between the insert 422 and the U-shaped sleeve 421. An anti-slip pad 423 is pasted on the inner surface of the U-shaped sleeve 421. The inner surface of the anti-slip pad 423 is provided with anti-slip texture or anti-slip protrusions.

[0034] The variable mounting bracket 4 can be rotated to adjust the angle. When installed in different ways, the arterial pressure monitoring sensor 2 can automatically rotate to adapt to the changing direction, avoiding the pulling of the infusion tube. In addition, the locking sleeve 42 has two installation methods. Its detachable nature allows the arterial pressure monitoring sensor 2 to be installed on the flexible substrate layer 1. When the upper arm needs to move, the arterial pressure monitoring sensor 2 can also be installed on the chest pocket of clothing, which is convenient to use.
