DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0025] The utility model provides a lifting infusion stand for obstetrics and gynecology nursing. Figure 1 , including: a supporting component, an adjusting component and a hanging component, the supporting component includes a base 1 and a lower column 101 arranged on the base 1, the interior of the lower column 101 is a hollow structure, and an adjusting component is arranged on the top of the lower column 101. The adjusting component mainly plays a role in adjusting the height of the infusion stand, including a lifter 2, and the hanging component includes an infusion pole 3. The bottom of the infusion pole 3 is fixedly connected to the lifter 2, and the lifter 2 is adjusted to move up and down, thereby realizing the overall height adjustment of the infusion stand.

[0026] See also Figure 2Specifically, the elevator 2 includes a worm 205 and a worm wheel 206 meshing with the worm 205. A nut 207 and a lead screw 208 meshing with the nut 207 are fixedly arranged at the bottom of the worm wheel 206. Specifically, a hole is opened at the center of the nut 207, and an internal thread is arranged in the hole. The lead screw 208 passes through the worm wheel 206 and the nut 207 and meshes with the internal thread of the nut 207. When the worm 205 is rotated, the worm wheel 206 rotates, driving the nut 207 to start rotating. When the nut 207 rotates, the internal thread of the nut 207 can convert the rotational motion into a linear motion, thereby realizing the up and down adjustment of the lead screw 208. The top of the lead screw 208 is fixedly connected to the bottom of the infusion rod 3. When the lead screw 208 moves, it will also move synchronously with the infusion rod 3.

[0027] In order to prevent dust from entering the interior of the elevator 2 and to prevent safety accidents during the lifting process, an upper column 301 is also sleeved on the outside of the infusion pole 3. The height of the upper column 301 is lower than the height of the infusion pole 3. When the infusion pole 3 is at the lowest position, it should be slightly higher than the upper column 301. The bottom of the upper column 301 is fixedly connected to the top of the lower column 101. At the same time, the bottom space of the upper column 301 is expanded to accommodate the worm wheel 206 and the worm 205 to prevent debris or human body from being drawn in during the transmission process and causing accidents. The upper column 301 can be fully enclosed or an inspection port can be opened on the upper column 301 to facilitate subsequent inspection and maintenance work.

[0028] See also Figure 1 The infusion pole 3 in the infusion stand plays the role of supporting the medicine liquid, so a hanger 302 for hanging the medicine liquid is arranged on the top of the infusion pole 3. In order to evenly bear the force when hanging the medicine liquid, the hangers 302 are symmetrically arranged along the center point of the top of the infusion pole 3, and there are at least two hangers to prevent the infusion stand from tipping over due to excessive force on one side when too much medicine liquid is hung.

[0029] See also Figure 1 , 2In this infusion stand, the adjustment methods include manual and electric adjustment modes. Specifically, one end of the worm 205 is connected to the handwheel 202, and a handle 203 is provided on the handwheel 202. When the infusion stand needs to be raised, the handwheel 202 is rotated clockwise, the worm 205 rotates forward, and the worm wheel 206 and the nut 207 are synchronously driven to rotate forward, and the screw rod 208 and the infusion rod 3 rise. When the infusion stand needs to be lowered, the handwheel 202 is rotated counterclockwise, the worm 205 is reversed, and the worm wheel 206 and the nut 207 are synchronously driven to reverse, and the screw rod 208 and the infusion rod 3 are lowered. The other end of the worm 205 is connected to the power end of the motor 201. An adjustment button 204 electrically connected to the motor 201 is also provided on the lower column 101. The adjustment button 204 has an up button and a down button. Its working principle is consistent with the manual adjustment principle. When the ascending button is pressed, the motor 201 rotates clockwise, the worm 205 rotates forward, synchronously driving the worm wheel 206 and the nut 207 to rotate forward, and the screw rod 208 and the infusion rod 3 ascend; when the descending button is pressed, the motor 201 rotates counterclockwise, synchronously driving the worm wheel 206 and the nut 207 to rotate reversely, and the screw rod 208 and the infusion rod 3 descend; at the same time, the adjusting button 204 and the motor 201 both adopt the inching operation, that is, the motor 201 rotates when the button is pressed, and stops rotating immediately when the motor 201 is released, so as to achieve the effect of push-and-go; the hand wheel 202 and the motor 201 are arranged on the outside of the lower column 101 for easy operation; due to the complex hospital environment, if it is simply electric adjustment, various emergencies such as inconvenience in power supply may be encountered; therefore, the two adjustment modes of manual and electric are set to cope with various operation scenarios well.

[0030] See also Figure 3, during the lifting and lowering process of the screw rod 208, if the screw rod 208 is not fixed by external force, the screw rod 208 will rotate in place with the nut 207 and will not make linear motion. Therefore, an anti-rotation device is also provided in the infusion stand. Specifically, the anti-rotation device includes a block 209 provided at the top of the screw rod 208 and a slot 303 matched with the block 209 provided at the bottom of the infusion rod 3. At the same time, two symmetrical sliding grooves 304 are provided on the inner side wall of the upper column 301. The sliding groove 304 is vertically arranged along the movement direction of the screw rod 208. A connecting rod 305 is also provided in the upper column 301. The connecting rod 305 passes through the slot 303 and the block 209 to fix the slot 303 and the block 209, and the two ends of the connecting rod 305 are arranged in the sliding groove 304. The connecting rod 305 can move up and down in the sliding groove 304 with the screw rod 208. When the worm 205 is rotated, the anti-rotation device can The screw rod 208 plays a limiting role, preventing the screw rod 208 from rotating in place with the nut 207, ensuring that the movement of the screw rod 208 is only linear motion, and can also provide a guiding effect for the screw rod 208 to ensure the stable rise of the screw rod 208. At the same time, it can also provide a limiting effect for the screw rod 208. When the connecting rod 305 rises to the highest point of the sliding groove 304, it will be blocked by the top of the sliding groove 304 and cannot rise any further. At this time, the motor 201 or the handwheel 202 can no longer rotate. Therefore, the length of the sliding groove 304 should be shorter than the height that the screw rod 208 can rise to, to prevent the screw rod 208 from rising too high and falling out of the nut 207, causing an accident. In actual applications, sliding devices such as guide grooves and balls can also be added to the contact surface of the sliding groove 304 and the connecting rod 305 to reduce the friction between the sliding groove 304 and the connecting rod 305, increase the transmission efficiency, and make the operator more labor-saving during operation.

[0031] It should be noted that the elevator 2 in the infusion stand can adopt a screw elevator or a commonly used ball screw elevator. Since the transmission methods of the two are different, the friction force is also different, so the self-locking property is different. In comparison, the screw elevator has slow transmission and strong self-locking property, while the ball screw has fast transmission efficiency and slightly weaker self-locking property. It can be selected according to the weight of the suspended medicine or actual usage requirements.

[0032] See also Figure 1 During the infusion process, the patient may need to get up and out of bed at any time. Therefore, in order to facilitate the movement of the infusion stand, four braked casters 102 are provided under the base 1. The four braked casters 102 are respectively installed on the four corners of the base 1. The braked casters 102 are medical standard parts with built-in silent effect. The infusion stand can be stopped by stepping on the brake device of the braked casters 102. When the infusion stand needs to be moved, the brake can be unlocked and it can be easily pushed. At the same time, when the infusion patient walks on the ground, the infusion stand can also provide center of gravity support to prevent the patient from accidentally falling when standing.

[0033] This infusion stand can flexibly adjust to different heights according to the height and body position of different patients. The electric and manual dual operation modes can adapt to the complex scenes in the hospital. The overall structure is simple and practical. It can save precious time for medical staff in infusion treatment and improve the convenience of treatment operation. Patients can also adjust the height of the infusion stand according to their needs at any time during the infusion process, which also provides patients with a more convenient and flexible infusion tool.
