Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an arm fixing device for a hospital bed. Background Art

[0002] In the field of medical emergency, cardiopulmonary resuscitation (CPR) is a vital rescue method, which can buy precious life time for patients in the case of cardiac arrest or respiratory arrest. However, when performing CPR, medical staff often face a challenge: how to effectively fix the patient's arms, especially for larger patients.

[0003] Traditional medical beds often do not have specially designed fixing devices for large patients, which results in obese patients' arms easily slipping off the bedside during cardiopulmonary resuscitation, making it difficult for medical staff to maintain effective compression, thus affecting the resuscitation effect.

[0004] Existing fixation methods usually rely on temporary solutions, such as using additional straps or relying on manual support. These fixation methods are not only time-consuming and labor-intensive, but also lack stability and reliability. Utility Model Content

[0005] The purpose of the utility model is to provide an arm fixing device for a hospital bed to solve the problem that existing fixing methods usually rely on temporary solutions, such as using additional straps or relying on manpower support. These fixing methods are not only time-consuming and labor-intensive, but also lack stability and reliability.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical scheme: an arm fixing device for a hospital bed, comprising a fixing column, both ends of the fixing column are rotatably provided with rotating blocks, an adjusting plate is rotatably provided on the outer wall of the fixing column, a plurality of fixing grooves are provided at equal angles on the outer walls of both ends of the fixing column, a spring is fixed inside the fixing groove, a clamping column is sleeved inside the fixing groove, the top end of the spring is connected to the bottom end of the clamping column, two clamping grooves are provided on the bottom surface of the adjusting plate, and one of the plurality of clamping columns is plugged into the inside of the clamping groove.

[0007] Preferably, limiting columns are fixed on both left and right ends of the fixed column, a limiting hole is opened on one side of the rotating block, the limiting hole and the limiting column are rotatably arranged, and the rotating block is connected to one side of the adjusting plate.

[0008] Preferably, an extension plate is slidably arranged inside the adjustment plate, limiting grooves are respectively provided on both sides of the inner wall of the adjustment plate, limiting blocks are respectively fixed on the left and right sides of the extension plate, and the limiting blocks are slidably arranged with the limiting grooves.

[0009] Preferably, a mounting block is fixed to one side of the fixing column, and a mounting opening is formed on a side of the mounting block away from the fixing column.

[0010] Preferably, two threaded holes are provided on the top surface of the mounting block, and bolts are connected to the internal threads of the threaded holes, and the bottom ends of the bolts extend to the inside of the mounting opening.

[0011] Preferably, a boosting block is fixed to the top end of the bolt, and a force-bearing plate is fixed to the bottom end of the bolt.

[0012] Compared with the prior art, the arm fixing device for a hospital bed using the above technical solution has the following beneficial effects:

[0013] 1. During use, when the medical staff bends the adjustment plate, the adjustment plate can be rotated on the outer wall of the fixed column through the rotating block. When the adjustment plate rotates on the outer wall of the rotating block, the clamping column will be retracted into the interior of the fixed slot due to the resistance of the clamping slot, and the spring will be in a retracted state. The medical staff can adjust the inclination angle of the adjustment plate according to the thickness of the patient's arm. When it is adjusted to a suitable angle, one of the several clamping columns will correspond to the clamping slot. At this time, the clamping column is not affected by the resistance, so the clamping column is reinserted into the interior of the clamping slot through the rebound of the spring, thereby locking the position of the adjustment plate;

[0014] It ensures that the patient's arm can be firmly fixed to the bedside during critical medical operations such as cardiopulmonary resuscitation (CPR) to prevent it from sliding off the bedside and ensure that the arm will not be displaced, thereby improving the efficiency of treatment and reducing possible additional damage to the patient;

[0015] 2. During use, the medical staff inserts the mounting block into both sides of the bed through the mounting port. At this time, the staff twists the power-assisting block, and the bolt is driven to rotate by the rotation of the power-assisting block. At this time, the force plate will contact the bed, and the contact area of ​​the bolt is increased by the force plate, so that the bolt can better fix the mounting block to the side of the bed. No additional straps or manpower support are required, which greatly saves the time and energy of medical staff. This ease of operation not only improves work efficiency, but also reduces the workload of medical staff. Medical staff pull the extension plate out from the inside of the adjustment plate, thereby extending the width of the adjustment plate, so that the device can better adapt to the body positions of different obese patients during use, thereby improving the applicability of the device.

DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0022] like Figure 1-Figure 4 As shown, the arm fixing device for a hospital bed comprises a fixing column 1, both ends of which are rotatably provided with a rotating block 2, an outer wall of the fixing column 1 is rotatably provided with an adjusting plate 3, a plurality of fixing grooves 4 are provided at equal angles on the outer walls of both ends of the fixing column 1, a spring 5 is fixed inside the fixing groove 4, a clamping column 6 is sleeved inside the fixing groove 4, the top of the spring 5 is connected to the bottom end of the clamping column 6, two clamping grooves 7 are provided on the bottom surface of the adjusting plate 3, one of the clamping columns 6 is plugged into the inside of the clamping groove 7, limiting columns 8 are fixed at both left and right ends of the fixing column 1, a limiting hole 9 is provided on one side of the rotating block 2, the limiting hole 9 is rotatably provided with the limiting column 8, and the rotating block 2 is connected to one side of the adjusting plate 3.

[0023] During use, when the medical staff bends the adjustment plate 3, the adjustment plate 3 can be rotated on the outer wall of the fixed column 1 through the rotating block 2. When the adjustment plate 3 rotates on the outer wall of the rotating block 2, the clamping column 6 will be retracted into the interior of the fixed groove 4 due to the resistance of the clamping groove 7, and the spring 5 will be in a retracted state. The medical staff can adjust the inclination angle of the adjustment plate 3 according to the thickness of the patient's arm. When it is adjusted to a suitable angle, one of the several clamping columns 6 will correspond to the clamping groove 7. At this time, the clamping column 6 is not affected by the resistance, so that the clamping column 6 is reinserted into the interior of the clamping groove 7 through the rebound of the spring 5, thereby locking the position of the adjustment plate 3;

[0024] It ensures that during critical medical operations such as cardiopulmonary resuscitation (CPR), the patient's arms can be firmly fixed to the bedside to prevent them from slipping off the bedside and ensure that the arms will not be displaced, thereby improving treatment efficiency and reducing possible additional damage to the patient.

[0025] like Figure 1 , Figure 2 and Figure 4 As shown, an extension plate 10 is slidably provided inside the adjustment plate 3, and limiting grooves 11 are respectively provided on both sides of the inner wall of the adjustment plate 3. Limiting blocks 12 are respectively fixed on the left and right sides of the extension plate 10, and the limiting blocks 12 are slidably provided with the limiting grooves 11. A mounting block 13 is fixed on one side of the fixed column 1, and a mounting opening 14 is provided on the side of the mounting block 13 away from the fixed column 1. Two threaded holes 15 are provided on the top surface of the mounting block 13, and the internal threads of the threaded holes 15 are connected with bolts 16, and the bottom end of the bolt 16 extends to the inside of the mounting opening 14, and a booster block 17 is fixed to the top end of the bolt 16, and a force plate 18 is fixed to the bottom end of the bolt 16.

[0026] During use, the medical staff inserts the mounting block 13 into both sides of the bed through the mounting opening 14. At this time, the staff twists the assisting block 17, and the rotation of the assisting block 17 drives the bolt 16 to rotate. At this time, the force plate 18 will contact the bed, and the contact area of ​​the bolt 16 is increased by the force plate 18, so that the bolt 16 can better fix the mounting block 13 on the side of the bed. No additional straps or manpower support are required, which greatly saves the time and energy of the medical staff. This ease of operation not only improves work efficiency, but also reduces the workload of the medical staff. The medical staff pulls the extension plate 10 out from the inside of the adjustment plate 3, thereby extending the width of the adjustment plate 3, so that the device can better adapt to the body positions of different obese patients during use, thereby improving the applicability of the device.
