Description

Technical Field

[0001] The invention relates to the technical field of medical auxiliary equipment, and in particular to a device for preventing hospitalized patients from falling out of bed. Background Art

[0002] Bed rails provide a handhold for getting in or out of bed, provide comfort and security, and reduce the risk of patients falling out of bed when transported. But bed rails also present potential risks, strangulation, suffocation, physical injury, or death when patients or parts of their bodies become trapped between the rails or between the bed rails and the mattress. Falls can cause more serious injuries when patients climb over the rails. Bruises, cuts, and abrasions can occur. When bed rails are used as restraints, they can cause agitation. Feelings of isolation or unnecessary restriction.

[0003] Therefore, in order to prevent accidents from causing harm to patients, after using the bed rails, nurses must closely observe whether the patients are adapting to the use process, increase the frequency of inspections, and increase the workload of medical staff.

The third driving part 20441 adopts a servo motor, and the third driving part 20441 drives the screw to rotate.

[0079] like Figure 3 and Figure 4 As shown, the telescopic frame includes a primary frame 2041, a secondary frame 2042, and a tertiary frame 2043 that are telescopically connected, and a fourth driving unit 2045 for driving the primary frame 2041, the secondary frame 2042, and the tertiary frame 2043 to telescopically move. A support leg 2046 is provided below the end of the tertiary frame 2043, and the two support legs 2046 are spaced apart along the length direction of the bed body 1. The fourth driving unit 2045 is connected to the bed body 1.

[0080] like Figure 4 As shown, the first frame 2041, the second frame 2042, and the third frame 2043 are all welded by rectangular square tubes, wherein the longitudinal beam 2047 arranged along the length direction of the bed body 1 adopts a downward curved arc tube to improve comfort. In addition, in order to prevent the patient from contacting the telescopic frame and causing impact, a cushioning material such as a cushioning pad is arranged on the upper layer of the telescopic frame. The fourth driving part 2045 adopts a telescopic cylinder or a hydraulic cylinder.

[0081] In this embodiment, by providing a telescopically connected first-level frame 2041, a second-level frame 2042, and a third-level frame 2043, and a fourth driving unit 2045 for driving the first-level frame 2041, the second-level frame 2042, and the third-level frame 2043 to telescope and move, it is possible to avoid occupying too much space under the bed, and by providing support legs 2046, the strength of the telescopic bed mechanism 2 is increased, further ensuring the reliability of receiving patients.

[0082] Still Figure 4 As shown, the support leg 2046 adopts a telescopic tube arranged along the height direction of the bracket 202. The upper end of the telescopic tube is connected to the three-stage bracket 202, and the support assembly 205 is connected to the three-stage bracket 202.

[0083] like Figure 5 As shown, the telescopic assembly 2032 includes a plurality of connecting rods 20321 hinged in a scissor-shaped manner, and a fifth driving part 20322 for driving one of the connecting rods 20321 to rotate.

A sliding block 20323 is provided on the pivot axis of every two connecting rods 20321, and a through hole is provided on the sliding block 20323. A telescopic rod 207 extending along the width direction of the bed body 1 is provided on the bracket 202, and the telescopic rod 207 passes through the through hole.

[0084] like Figures 6 to 8As shown, the support assembly 205 includes a mounting seat 2051 connected to the end of the three-stage frame 2043, a support body 2052 disposed on the mounting seat 2051, and an elastic sleeve 2053 covering the support body 2052. The support body 2052 includes a ball head 20521 and a screw rod 20522 connected up and down. The locking assembly 206 is connected to the telescopic rod 207.

[0085] The locking assembly 206 includes a locking body 2061, a locking member 2062 sleeved on the locking body 2061, and a power assembly driving the locking member 2062 to move downward. A ball hole matching the ball head 20521 is provided in the locking body 2061, and a plurality of first opening grooves 20611 are provided in the circumference of the locking body 2061. When the ball head 20521 is stuck in the ball hole, the power assembly drives the locking member 2062 to move to the lower part of the ball hole, and the locking member 2062 locks the locking body 2061 due to elastic retraction, and the first opening grooves 20611 shrink.

[0086] Still Figures 6 to 8 As shown, the locking body 2061 includes a straight segment 20612, a spherical segment 20613, a first conical segment 20614 and a first conical segment 20615 connected in sequence from top to bottom. The ball hole is formed in the spherical segment 20613, and the first opening groove 20611 extends from the spherical segment 20613 to the first conical segment 20615. In the initial state, the locking member 2062 is arranged at the intersection of the straight segment 20612 and the spherical segment 20613. Figure 6 As shown, the initial state in this embodiment is the state where the support assembly 205 has not yet been inserted into the locking assembly 206. At this time, the abutment end of the drive sleeve 2064 described below is also arranged at the intersection of the straight segment 20612 and the spherical segment 20613.

[0087] Still Figures 6 to 8 As shown, the elastic sleeve 2053 includes a hemispherical section 20531, a second conical section 20532 and a second conical section 20533. The elastic sleeve 2053 is provided with a second opening groove 20534 arranged along the circumferential direction, and the second opening groove 20534 is arranged on the second conical section 20532 and the second conical section 20533. The taper of the first conical section 20615 is not less than that of the second conical section 20533. When the support assembly 205 and the locking assembly 206 are in a locked state, the first conical section 20614 and the second conical section 20532 are located at the same height.

[0088] Still Figures 6 to 9As shown, the power assembly includes a sixth driving part 2063, a driving sleeve 2064 connected to the power output end of the sixth driving part 2063, and the driving sleeve 2064 is sleeved on the outer side of the locking body 2061. A pressing shaft 2065 is also elastically connected inside the driving sleeve 2064, and an elastic member 2066 is provided between the pressing shaft 2065 and the driving sleeve 2064. When the driving sleeve 2064 moves downward, the pressing shaft 2065 first abuts on the straight section 20612, the elastic member 2066 is gradually compressed, and the lower end of the driving sleeve 2064 abuts on the locking member 2062. When the driving sleeve 2064 continues to move downward, the driving sleeve 2064 drives the locking member 2062 to move downward to the first shrinking section 20614. The sixth driving part 2063 adopts a telescopic cylinder or a hydraulic cylinder.

[0089] Preferably, if Fig. 9 As shown, a plurality of third opening grooves 20641 are provided along the circumferential direction on one side of the drive sleeve 2064 near the abutting end. The abutting end of the drive sleeve 2064 is tapered, and the minimum outer diameter is larger than the inner hole of the locking member 2062. Figure 3 and Fig. 9 As shown, the locking assembly 206 is further provided with a connecting seat 208 , and the connecting seat 208 is connected to the end of the telescopic rod 207 .

[0090] In addition, if Figure 7 As shown, the screw portion 20522 is further provided with a screw-connected rotating disk 2067. When the rotating disk 2067 is driven to move upward, the taper of the second tapered section 20533 increases, and the width of the second opening groove 20534 increases. By providing the rotating disk 2067, the rotating disk 2067 can be manually driven to gradually move upward to drive the taper of the second tapered section 20533 to increase, thereby increasing the taper of the first tapered section 20615 on the locking body 2061 accordingly, so that the diameters of the first shrinking section 20614 and the second shrinking section 20532 increase, and the locking member 2062 is thus lifted upward and sleeved on the outer side of the abutting end of the driving sleeve 2064. The locking member 2062 is restored to its initial position by the driving of the sixth driving portion 2063.

[0091] The locking piece 2062 of this embodiment adopts a circular rubber ring, and the driving sleeve 2064, the locking body 2061, and the elastic sleeve 2053 are all made of spring steel. In addition, the elastic force of the driving sleeve 2064 should be greater than that of the locking body 2061 and the elastic sleeve 2053, so that the locking piece 2062 can be sleeved on the abutting end of the driving sleeve 2064.

[0092] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
