[0002] The ECG monitor features a connector for connecting to a pressure sensor, which connects to the NS drainage and flushing tubes. Both ends and the top of the pressure sensor are connected to infusion tubing and extension tubing, respectively. A three-way switch for adjusting arteriovenous access is located on each front side of the pressure sensor. The pressure sensor is located at the patient's bedside and needs to be adjusted in height based on the patient's position to zero the arterial blood pressure before measuring it. Utility Model Content
[0003] The purpose of the present utility model is to provide a pressure sensor holder to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.
[0004] The technical solution adopted to solve the above technical problems is: a pressure sensor fixer, comprising: a fixed plate; a moving block, the moving block slides vertically on the fixed plate, the moving block is installed with a guide column, the guide column is slidably provided with a clip, an elastic member is installed between the clip and the moving block, the elastic member provides an elastic force to bring the clip close to the fixed plate; an adjusting screw, one end of the adjusting screw is installed with an adjusting handle, and the other end is threaded through the moving block and contacts the fixed plate.
[0005] This technical solution has at least the following beneficial effects: the fixing plate is installed on one side of the bed rail by means of screws, glue, etc., and the pressure sensor is clamped in the clip, which can relatively fix the position of the pressure sensor. By loosening and tightening the adjustment screw, the height position of the movable block can be adjusted longitudinally, thereby facilitating the adjustment of the height of the pressure sensor according to the patient's body position, facilitating zero calibration, obtaining the most accurate invasive arterial blood pressure monitoring data, and facilitating the observation of the patient's condition.
[0006] As a further improvement to the above technical solution, the movable block is provided with a collar sleeved on the fixed plate, and the collar is vertically slidably connected to the fixed plate, thereby improving the stability of the relative sliding between the movable block and the fixed plate and facilitating the longitudinal movement of the movable block.
[0007] As a further improvement of the above technical solution, the movable block is provided with a sliding groove in the transverse direction, a slider is slidably arranged in the sliding groove, and the guide column is mounted on the slider. The slider can slide transversely in the sliding groove, so that the relative position of the clamp can be adjusted according to needs.
[0008] As a further improvement to the above technical solution, the elastic member is a coil spring with its ends fixed to the slider and the clamp, respectively. When the clamp is opened, the coil spring is stretched. After the pressure sensor is placed in the clamp and released, the return force of the coil spring pulls the clamp toward the slider, causing the clamp to securely press the pressure sensor against the moving block, thereby stabilizing the pressure sensor's position.
[0009] As a further improvement of the above technical solution, two of each of the slider, the elastic member, the guide post and the clamp are provided. The pressure sensor is fixed with two clamps, thereby improving the stability of the pressure sensor.
[0010] As a further improvement to the above technical solution, the invention further comprises a tie rod, each end of which is provided with a transverse groove for the two guide posts to slide transversely therein, and a handle is provided in the middle of the tie rod. The transverse grooves on both sides of the tie rod are inserted into the side of the guide post near the coil spring, and by pulling the handle away from the moving block, the tie rod can simultaneously push the clamps on both sides, thereby facilitating the insertion of the pressure sensor into the two clamps and securing the pressure sensor.
[0011] As a further improvement to the above technical solution, one end of the chute passes through one side of the moving block and is detachably mounted with a blocking block. By removing the blocking block, the slider can be easily installed and removed, thereby facilitating adjustment of the number of clips and also facilitating replacement or repair of clips and other components.
[0012] As a further improvement of the above technical solution, the blocking block is provided with a bolt threadedly connected to the moving block. By installing or removing the bolt, the blocking block can be easily installed or removed.
[0013] As a further improvement to the above technical solution, two winding posts are arranged side by side horizontally at the bottom of the fixing plate, with a baffle mounted on one end of each post away from the fixing plate. The extension tube connected to the pressure sensor can be wound around the two winding posts, thereby allowing the extension tube to be stored and organized, preventing it from being pressed against the patient's skin due to its length and causing indentations. Storing the extension tube prevents the patient from removing the tube, thereby reducing the risk of extubation and tube removal.
[0014] As a further improvement to the above technical solution, an L-shaped plate is provided on top of the fixing plate, a fixing screw is threadedly mounted on the L-shaped plate, and a fixing handle is provided at one end of the fixing screw. The fixing plate can be easily fixed to the bed rail by clamping the L-shaped plate on the top of the bed rail and then rotating the fixing screw until it contacts the bed rail.

[0023] Reference Figure 1-2The pressure sensor holder includes a fixing plate 100, a moving block 200, and an adjusting screw 300. An L-shaped plate 600 is formed on the top of the back of the fixing plate 100. A fixing screw 610 is provided at one end of the L-shaped plate 600 that is parallel to the fixing plate 100. The middle part of the fixing screw 610 is threadedly connected to the L-shaped plate 600. A fixing handle 620 is provided at the end of the fixing screw 610 away from the fixing plate 100, and a rubber anti-skid pad is attached to the end surface of the fixing screw 610 that is close to the fixing plate 100. The L-shaped plate 600 is embedded in the top position of the bed rail, and then the fixing screw 610 is rotated by grasping the fixing handle 620, so that the end of the fixing screw 610 with the rubber anti-skid pad is pressed against the bed rail, so that the fixing screw 610 and the fixing plate 100 clamp the bed rail, so that the fixing plate 100 is firmly installed on the bed rail.
[0024] A collar 210 is mounted on the bottom of the fixed plate 100 and can slide vertically on the fixed plate 100. The collar 210 is integrally formed with the movable block 200, with the movable block 200 positioned in front of the collar 210. It should be noted that a protrusion corresponding to the height of the L-shaped plate 600 protrudes from the top of the back of the fixed plate 100. This ensures that when the fixed plate 100 is secured to the bed rail, there is a gap between the fixed plate 100 and the bed rail for the collar 210 to move longitudinally.
[0025] One end of the adjusting screw 300 is threaded into the right side wall of the collar 210. This end of the adjusting screw 300 also threads through the collar 210 and presses against a side wall of the fixed plate 100. This allows the movable block 200 to be fixed at a predetermined height. An adjustment handle 310 is provided on the end of the adjusting screw 300 that is away from the fixed plate 100. This handle is shaped like a plum blossom. Gripping the adjustment handle 310 facilitates loosening and tightening the adjusting screw 300, thereby facilitating adjustment of the movable block 200's height.
[0026] The movable block 200 is provided with two sliding blocks 230. Specifically, a slide groove 220 is provided at the front bottom of the movable block 200. The slide groove 220 is arranged horizontally and one end thereof passes through a side of the movable block 200. The cross section of the slide groove 220 is "T"-shaped. Both slide blocks 230 are inserted into the slide groove 220 from one end of the slide groove 220 passing through the movable block 200, and the two slide blocks 230 can slide within the slide groove 220. A blocking block 231 is installed at the end of the slide groove 220 passing through the movable block 200. A bolt 232 is passed through the blocking block 231. The head of the bolt 232 contacts the blocking block 231, and the rod of the bolt 232 passes through the blocking block 231 and is screwed into the movable block 200, thereby facilitating the installation and removal of the blocking block 231. The cross sections of the blocking block 231 and the slide block 230 are both "T"-shaped to fit the slide groove 220.
[0027] A guide post 240 is connected to the side of the slider 230 away from the bottom wall of the chute 220. The axis of the guide post 240 is perpendicular to the front of the movable block 200. A clip 250 is slidably mounted on the guide post 240. The clip 250 can be made of plastic. One end of the clip 250 is sleeved onto the guide post 240, and the other end is bent to form an arcuate segment. The arcuate segment forms a clamping space between the movable block 200. An elastic member 260 is mounted between the clip 250 and the slider 230. The elastic member 260 is a coil spring. One end of the coil spring is fixed to the front of the slider 230, and the other end is fixed to the side of the clip 250 closer to the slider 230. The coil spring is sleeved on the outside of the guide post 240. A limiting block is mounted on the end of the guide post 240 away from the slider 230. The diameter of the limiting block is larger than that of the guide post 240, thereby preventing the clip 250 from detaching from the guide post 240.
[0028] A tie rod 400 is positioned between the two clamps 250. Both ends of the tie rod 400 are provided with transverse grooves 410. These grooves 410 are arranged horizontally, giving the tie rod 400 an overall horizontal "H" shape. A handle 420 is mounted in the middle of the tie rod 400, with its axis perpendicular to the front of the tie rod 400. A spherical block is positioned on the end of the handle 420 facing away from the tie rod 400. After installing the first slider 230, one of the transverse grooves 410 of the tie rod 400 is inserted into the already installed guide post 240, with the tie rod 400 positioned on the side of the clamp 250 closest to the slider 230. When installing the second slider 230, the other transverse groove 410 of the tie rod 400 is also inserted into the guide post 240 being installed, so that both transverse grooves 410 of the tie rod 400 are inserted into the two guide posts 240. The blocking block 231 is then installed.
[0029] During use, the fixing plate 100 is first fixed to the bed rail via the L-shaped plate 600 and the fixing screw 610. By pulling the handle 420, the two ends of the cross-tie rod 400 push the clamps 250 to overcome the elastic force of the coil spring and open the clamping space. The pressure sensor is placed in the clamping space. The handle 420 is then released. Under the action of the return force of the coil spring, the two clamps 250 firmly press the two sides of the pressure sensor, thereby firmly fixing the pressure sensor to the movable block 200. It should be noted that the position of the two clamps 250 needs to be adjusted horizontally in advance to a position away from the pressure sensor adjustment handle to prevent obstruction of the pressure sensor adjustment operation.
[0030] A long strip is installed at the bottom of the fixed plate 100, and winding posts 500 are fixedly installed on both sides of the front of the long strip, and the two winding posts 500 are arranged side by side in a horizontal direction. A baffle 510 is provided at the end of the winding post 500 away from the long strip. The cross section of the baffle 510 is square, and the length and width of the baffle 510 are both larger than the diameter of the winding post 500. After the pressure sensor is installed on the moving block 200 and the height position of the moving block 200 is adjusted, the infusion tube connected to the pressure sensor can be wound in an "8" shape on the two winding posts 500, so that the longer extension tube can be sorted and stored, preventing the extension tube from being too long and being pressed against the patient's skin and causing indentations. Storing the extension tube can prevent the patient from pulling out the tube, which can reduce the risk of pulling out the tube and falling off the tube.
[0031] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
