Abstract
Description
Technical Field
[0001] This utility model relates to the field of arterial pressure sensor installation technology, specifically to an arterial pressure sensor fixator. Background Technology
[0002] Arterial pressure sensors, also known as invasive pressure sensors, sense changes in pressure, convert pressure signals into electrical signals, and transmit them to external devices for processing and analysis via connecting lines. In the medical field, invasive pressure sensors are mainly used to monitor patients' physiological parameters such as blood pressure and cardiac pressure, providing doctors with diagnostic and treatment information.
[0003] To ensure the reliability of monitoring data and avoid deviations, medical arterial pressure sensors are typically positioned at the same level as the patient's heart during use. This is usually achieved by fixing the sensor to the head of the bed using a specialized mounting device. Existing mounting devices generally include a base and a support rod, with a connecting plate on the outside of the support rod. Several limiting rails and a top plate are fixed to one side of the connecting plate to hold the arterial pressure sensor in place. However, since the arterial pressure sensor is directly inserted into the limiting rails, wear and deformation inevitably occur on the sides of the limiting rails and top plate over time, easily causing the sensor to detach. Furthermore, the conduit connecting the arterial pressure sensor is usually secured to the side of the connecting plate with tape, which can easily detach when pulled. Utility Model Content
[0004] The technical problem this invention aims to solve is that existing arterial pressure sensor fixing devices are prone to failure due to wear and tear, and are also inconvenient for fixing the conduit.
[0005] To solve the above problems, the technical solution adopted by this utility model is an arterial pressure sensor fixator, including a base, a support rod fixed on the upper side of the base, a pair of connecting rods fixed at the top of the support rod, a fixing structure on the outside of the connecting rod, the fixing structure including a connecting plate, a number of pairs of limiting slide rails fixed on one side of the connecting plate, a frame fixed on the other side of the connecting plate at each pair of limiting slide rails, a pair of vertical holes and a horizontal hole opened on the side of the connecting plate at the frame, a push plate slidably provided on the inner side of the frame, a top plate fixed on the side of the push plate at the vertical hole and a baffle fixed on the side of the push plate at the horizontal hole, a compression spring sandwiched between the push plate and one side of the inner side of the frame, a number of extension plates fixed on the upper and lower sides of the connecting plate, and a pair of wire clamping rods fixed on the side of the extension plates.
[0006] As a further embodiment of this utility model: a sleeve is fixed on the side of the connecting plate at the connecting rod, and a fastening bolt is threaded and rotated on one side of the sleeve. One end of the fastening bolt abuts against the side of the connecting rod, which facilitates fixing the position of the connecting plate and adjusting the height of the connecting plate.
[0007] As a further embodiment of this utility model: an arterial pressure sensor body is inserted into a pair of limiting slide rails, the bottom end of the arterial pressure sensor body is in contact with the baffle, and one end of the top plate abuts against one side of the arterial pressure sensor body, so as to clamp the arterial pressure sensor body.
[0008] As a further embodiment of this utility model: the top edge of the top plate is provided with rounded corners to facilitate the insertion of the arterial pressure sensor body.
[0009] As a further aspect of this invention: the height of the baffle relative to the push plate is greater than the height of the top plate relative to the push plate, so that the baffle can block the arterial pressure sensor body.
[0010] Compared with the prior art, the advantages of this utility model are as follows: This patent adds a push plate structure, which pushes the top plate to clamp the arterial pressure sensor body in the limiting slide rail, which can better fix its position and eliminate the problem of clamping failure caused by wear. In addition, a wire clamping rod structure is added to facilitate the fixation of the wire tube. Attached Figure Description

A fastening bolt 12 is threaded and rotated on one side of the sleeve 11. One end of the fastening bolt 12 abuts against the side of the connecting rod 3, which makes it easy to fix the position of the connecting plate 4 and to adjust the height of the connecting plate 4.
[0021] Combined with appendix Figure 2-4It can be seen that the fixing structure includes a connecting plate 4, and several pairs of limiting slide rails 5 are fixed on one side of the connecting plate 4; an arterial pressure sensor body 13 is inserted into a pair of limiting slide rails, the bottom end of the arterial pressure sensor body 13 is in contact with the baffle 7.2, and one end of the top plate 7.1 abuts against one side of the arterial pressure sensor body 13 to facilitate clamping the arterial pressure sensor body 13. On the other side of the connecting plate 4, a frame 6 is fixed at each pair of limiting slide rails 5. A pair of vertical holes 6.1 and a horizontal hole 6.2 are opened on the side of the connecting plate 4 at the frame 6. A push plate 7 is slidably provided on the inner side of the frame 6, and a push plate 7 is fixed at the vertical hole 6.1 on the side of the push plate 7. A baffle 7.2 is fixed at the top plate 7.1 and the horizontal hole 6.2. The top edge of the top plate 7.1 is rounded to facilitate the insertion of the arterial pressure sensor body 13. The height of the baffle 7.2 relative to the push plate 7 is greater than the height of the top plate 7.1 relative to the push plate 7, so that the baffle 7.2 can block the arterial pressure sensor body 13. A compression spring 8 is sandwiched between the push plate 7 and one side of the frame 6 to push the push plate 7 outward. Several extension plates 9 are fixed on the upper and lower sides of the connecting plate 4. A pair of wire clamping rods 10 are fixed on the side of the extension plate 9.

Then, the fastening bolt 12 is tightened. Then, the arterial pressure sensor body 13 with the connected tubing can be directly inserted into a pair of limiting slide rails 5. When inserted, the top plate 7.1 will be pressed into the frame 6, and at the same time, the push plate 7 will press the compression spring 8. At the same time, the reaction force of the compression spring 8 will push the top plate 7.1 outward to clamp the arterial pressure sensor body 13, thus fixing the arterial pressure sensor body 13. Then, the tubing can be positioned by passing it around a pair of wire clamping rods 10.
