Description

Technical Field

[0001] The present invention belongs to the technical field of medical equipment, and in particular relates to a split-type transfer device for moving critically ill patients to an examination bed. Background Art

[0002] In hospital ICUs, imaging departments, and other scenarios, critically ill patients often need to be transferred from their beds to CT / MRI / examination beds for diagnosis or treatment. Due to the patients' fragile physical conditions, traditional manual transfer methods have problems such as low efficiency, high labor intensity, and easy to cause secondary injuries. Some hospitals use "ceiling track transfer machines", but the tracks need to be fixed and installed, which lacks flexibility.

[0003] While some existing automated transport equipment incorporates mechanical assistance, it still suffers from technical flaws. For example, some devices use rigid carriers to carry patients, which cannot conform to the body's curves and can easily cause skin compression. Some devices also lack precise control and stability during the transport of critically ill patients, making them particularly prone to complications such as wound lacerations and dislodged medical circuits. When patients are placed on the examination bed, they may experience positional deviations, resulting in lower transport efficiency. Furthermore, bed sheets are prone to wrinkling and shifting during transport with most devices, impacting patient comfort and safety. Laying and leveling bed sheets often relies on manual labor, which is time-consuming and labor-intensive.

[0004] To this end, we provide a split transfer device for moving critically ill patients to an examination bed to solve the above problems. Summary of the Invention

[0020] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example 1 In order to solve the problem that some existing transfer devices use rigid carriers to carry patients, which cannot fit the curve of the human body, easily cause pressure on the patient's skin, and lack precise control and stability during the transfer process, please refer to Figure 1-Figure 5 The present invention provides a split transfer device for moving critically ill patients to an examination bed, comprising a transfer bed body 1 and a movable base frame 2 arranged at the bottom of the transfer bed body 1, a flexible bed sheet 3 for carrying the patient is laid on the transfer bed body 1, a top plate 4 is provided above the transfer bed body 1, and suspension components 5 for lifting the flexible bed sheet 3 as a whole are provided at the four corners of the bottom of the top plate 4; a first driving mechanism 6 for driving the top plate 4 to move horizontally is provided above the top plate 4, and a second driving mechanism 7 for driving the first driving mechanism 6 to move vertically is provided on one side of the first driving mechanism 6, and the second driving mechanism 7 is fixedly mounted on the movable base frame 2.

[0022] The suspension assembly 5 includes a suspension rod 501 fixed to the bottom of the top plate 4 and multiple slings 502 attached to the sides of the suspension rod 501. The edges of the flexible sheet 3 are provided with multiple rings 301 for connecting to the slings 502. The ends of the slings 502 are equipped with quick-connect fittings, such as hooks or buckles, for secure and efficient connection to the rings 301 on the flexible sheet 3. During transport, the slings 502 are connected to the rings 301 on the edge of the flexible sheet 3 in a one-to-one manner. The flexible sheet 3 can be made of a medical-grade nylon and polyester blend with a non-slip surface treatment (such as embossing). High-strength webbing is sewn along the edges to support the tension of the slings 502.

[0023] To address the potential safety hazard of the device tipping over due to a shifted center of gravity during transport and enhance its load-bearing stability, telescopic frames 8 are installed on both sides of the mobile chassis 2. These frames extend beneath the examination bed during transport to expand the device's support area and improve stability during transport. Telescopic frames 8 include a movable arm 801 and a movable module 802 for driving the movable arm 801 horizontally. The movable module 802 is fixed to the mobile chassis 2. First telescopic cylinders 803 are installed on the top surfaces of both ends of the movable arm 801. The telescopic ends of the first telescopic cylinders 803 are equipped with cushioning pads 804 for ground contact. The first telescopic cylinders 803 can be driven by electric push rods, pneumatic cylinders, or hydraulic cylinders. Their operation is controlled by a control system based on positioning feedback signals.

[0024] like Figure 1 、 Figure 3-Figure 4 As shown, the transfer device also includes four positioning components 9, which are arranged in a matrix at the four corner areas of the flexible bed sheet 3 for positioning during the process of the flexible bed sheet 3 being lowered to the examination bed; the positioning component 9 includes a second telescopic cylinder 901 fixed on the top surface of the end of the movable arm 801, and a positioning socket 902 for plugging with the boom 501 is provided on the top surface of the telescopic end of the second telescopic cylinder 901; a laser emitter 503 is provided at the bottom of the boom 501, and a laser receiver matching the laser emitter 503 is provided in the positioning socket 902, and the laser emitter 503 and the laser receiver constitute a photoelectric beam system, which can be used for real-time detection of the relative position between the boom 501 and the positioning socket 902, to assist in completing automatic centering and plugging operations; fixing rings 302 for the second telescopic cylinder 901 to pass through are provided at the four corners of the flexible bed sheet 3; the inner diameter of the fixing ring 302 is larger than the outer diameter of the second telescopic cylinder 901. The second telescopic cylinder 901 can be driven by an electric push rod, a pneumatic cylinder or a hydraulic cylinder, and its movement is controlled by a control system according to a positioning feedback signal.

[0025] To prevent harmful gases from escaping during transfer and potentially affecting the health of surrounding personnel and the patient, the telescopic rod of the second telescopic cylinder 901 is provided with a plurality of suction holes 903 on the side of the flexible sheet 3 facing the patient. These holes are used to absorb volatile harmful gases or odorous gases produced by the patient, preventing them from spreading into the environment. These holes 903 are connected to an external negative pressure device via an internal airway, forming a localized air circulation system and reducing the risk of cross-infection. The external negative pressure device can be installed within the housing of the second drive mechanism 7 and also incorporates a high-efficiency air filtration module, such as a HEPA and activated carbon composite filter element, to effectively purify harmful gases or odorous gases.

[0026] When the patient on the transfer bed 1 needs to be transferred to the examination bed, the mobile base frame 2 is first controlled to move the entire device to the side of the examination bed, and then the telescopic base frames 8 on both sides of the mobile base frame 2 are started. The movable arm 801 is driven by the mobile module 802 to extend horizontally to the bottom of the examination bed. When it reaches the predetermined position, the first telescopic cylinder 803 pushes the buffer pad 804 down until it is in close contact with the ground to stabilize the support device. Then, the second driving mechanism 7 is started to drive the top plate 4 down at a stable speed, so that the sling 502 of the suspension assembly 5 is connected with the ring 301 on the edge of the flexible bed sheet 3, and then the flexible bed sheet 3 and the patient are lifted up steadily at a uniform speed; at this time, the first driving mechanism 6 intervenes to drive the top plate 4 to drive the lifted patient to move toward the examination bed, and with the help of the built-in The positioning system realizes precise positioning, so that the top plate 4 stops just above the examination bed. During the positioning process, the laser emitter 503 at the bottom of the boom 501 emits laser, which cooperates with the laser receiver in the positioning socket 902 to accurately calibrate the position of the top plate 4. After confirmation, the second drive mechanism 7 is started again to steadily lower the flexible bed sheet 3 and the patient as a whole at a stable speed. The boom 501 is inserted into the positioning socket 902 until the flexible bed sheet 3 is completely flat and supported on the examination bed. Finally, the connection between the sling 502 and the ring 301 is disconnected, and the first drive mechanism 6 and the second drive mechanism 7 work together to reset the top plate 4 to above the transfer bed body 1, and the flexible bed sheet 3 is restricted to the examination bed by the telescopic rod of the second telescopic cylinder 901, completing the entire transfer process.

[0027] Example 2 On the basis of the first embodiment, in order to solve the problem that the bed sheet is easily wrinkled or misplaced when hanging it on the examination bed in the existing transfer device, such as Figure 4 、 Figure 6 As shown, the positioning assembly 9 also includes a stretching unit 904 for pulling the flexible bed sheet 3 to lay it flat on the examination bed; the stretching unit 904 includes a rubber block 904b and an electric telescopic rod 904a for driving the rubber block 904b to move, and the electric telescopic rod 904a is embedded in the telescopic rod of the second telescopic cylinder 901; a circular groove 303 is provided on the inner wall of the side of the fixing ring 302 facing away from the flexible bed sheet 3, and the rubber block 904b is inserted into the circular groove 303 to drive the flexible bed sheet 3 to move, so as to realize automatic tensioning and flat laying of the flexible bed sheet 3.

[0028] The electric telescopic rod 904a drives the rubber block 904b to be inserted into the circular groove 303 of the fixing ring 302, pulling the four corners of the flexible bed sheet 3 to achieve tensioning, thereby achieving automatic positioning and flattening of the flexible bed sheet 3.

[0029] Example 3 On the basis of the first and second embodiments, in order to solve the problem of the patient's body position changing and wound stretching due to shaking during side lying or transportation, as shown in FIG. Figure 1 、 Figure 7 As shown, the transfer device further includes a plurality of limit assemblies 10 provided at the bottom of the top plate 4. The limit assemblies 10 are used to be attached to both sides of the patient's body to limit lateral sliding or displacement of the patient during the transfer process.

[0030] The limiting assembly 10 includes a limiting rod body 1001, a frame body 1004 fixedly arranged on the top of the limiting rod body 1001, a support plate 1002 fixedly sleeved on the upper part of the limiting rod body 1001, and an airbag 1005 fixedly sleeved on the lower part of the limiting rod body 1001. The airbag 1005 is made of flexible material and can be filled with air or gel inside. It has good cushioning performance and can adapt to the patient's body shape to improve safety and comfort; a strip through hole 401 for the limiting rod body 1001 to pass through is provided on the top plate 4. The strip through hole 401 extends laterally to allow the limiting assembly 10 to adjust its position laterally within a certain range. A plurality of equally spaced limiting through holes 402 are provided on both sides of the strip through hole 401. A rod 1003 for inserting into the limiting through hole 402 to lock the limiting assembly 10 is fixedly provided at the bottom of the support plate 1002.

[0031] The position of the limiting assembly 10 is adjusted according to the patient's body shape. The limiting rod 1001 is slid horizontally along the strip-shaped through hole 401 to the appropriate position. The rod 1003 at the bottom of the support plate 1002 is aligned with the limiting through hole 402 at the corresponding position. The limiting rod 1001 is pressed vertically downward to fully insert the rod 1003 into the limiting through hole 402 to lock the assembly position. The limiting position and force can be flexibly adjusted according to the patient's different body shapes and lying postures. The limiting assembly 10 maintains synchronization and stability with the patient, providing additional lateral support for the patient, avoiding the patient's body deviation due to the inertia of the device's movement, making the entire transfer process smoother and reducing the patient's discomfort caused by changes in body position. For example, it can be used for the side-lying transfer of patients with spinal injuries.

[0032] The above embodiment merely represents one embodiment of the present invention. While the description is relatively specific and detailed, it should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the scope of the present invention, and such modifications and improvements are all within the scope of protection of the present invention.
