Description

Technical Field

[0001] The invention relates to the field of nursing supports, and more particularly to an adjustable nursing support. Background Art

[0002] In clinical work in hospitals, the infusion stand is a common piece of equipment, which is mainly used to hang infusion bottles for intravenous infusion for patients. Intravenous infusion usually takes a long time. When the patient needs to go out or go to the bathroom, the infusion bottle needs to be removed and held high to prevent the infusion bottle from being too low, which may cause blood backflow in the human body and cause safety hazards.

[0003] With the increase in the number of patients, medical staff cannot pay attention to each patient in time, resulting in patients who are more tired during infusion not paying attention to the infusion bottles that need to be replaced in time, which can easily cause the infusion tube to enter air into the human body, and severe cases require surgical rescue. Secondly, when there are too many patients, the traditional infusion stand needs to be placed on the side of the bed when in use, making the limited space in the ward more crowded, and there is also the risk of being knocked over by patients and their families in the same ward. When in use, the hanging height of the infusion bottle cannot be adjusted accordingly, so when the patient changes his posture, it cannot ensure that the infusion bottle maintains the same height difference with the patient's infusion site, resulting in different infusion fluid intensities, which causes changes in the infusion speed and easily causes discomfort to the patient.

[0004] If the infusion pressure is too low, it is easy to prolong the infusion time, the liquid flow rate will slow down, and the entire infusion process will be prolonged. This not only increases the patient's discomfort, but may also affect the progress of the treatment plan. In the treatment of some chronic diseases, reasonable control of the infusion pressure helps the drug to better penetrate into tissue cells and improve the efficacy of the drug. If the pressure is too low, the drug penetration rate will slow down, which may reduce the treatment effect. When the pressure is too high, it will cause excessive pressure on the patient's vascular system, which is not conducive to the treatment of the patient.

[0005] However, it is inconvenient to adjust the height of traditional infusion stands. Medical staff usually need the assistance of others to adjust the height of the stand, which is inconvenient to operate. Especially when there are many patients and the medical staff is under pressure, it cannot meet the current medical needs.

[0006] In order to solve the above problems, an adjustable nursing support is proposed. Summary of the invention

DETAILED DESCRIPTION

[0037] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0038] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0039] In the present invention, unless otherwise specified, the directions used, such as "up" and "down", usually refer to the directions shown in the drawings, or to the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.

[0040] For examples, see Figure 1 - Fig. 9 , an adjustable nursing bracket, including a back plate 1, a fixing plate is fixedly connected to the outer side of the back plate 1, a bolt is connected to the inner thread of the fixing plate, and the inner end of the bolt is fixedly connected to the wall. Specifically, the entire back plate 1 is installed on the wall, so as to save the regional space of the infusion room. A shell 2 is fixedly connected to the middle part of the outer side of the back plate 1, and vertical displacement mechanisms are symmetrically arranged on both sides of the shell 2. A buzzer is arranged at the shell 2. Specifically, the vertical displacement mechanism is divided into two groups, which is convenient for patients with different needs to use. The vertical displacement mechanism includes a rotating slot 3, and the rotating slot 3 is symmetrically arranged on both sides of the outer end of the shell 2. Side slots 4 are symmetrically arranged on both sides of the shell 2. Active cavities 5 are arranged at the tops of the two side slots 4. Screws 6 are rotatably connected in the two rotating slots 3, and damping rubber is arranged at the rotation connection between the two screws 6 and the rotating slot 3. Specifically, in order to carry out the following When lowering and adjusting the height, the infusion bottle is prevented from falling too fast, so as to ensure the stable descent of the infusion bottle. The outer walls of the two screws 6 are threadedly connected with sliding components, and the sliding component includes a threaded sleeve block 7, and the threaded sleeve block 7 is threadedly connected to the outer wall of the screw 6. One side of the threaded sleeve block 7 is fixedly connected with an outer sleeve plate 12, and the outer end of the threaded sleeve block 7 is connected with a hanging component. Specifically, the hanging component can be adjusted by displacement to meet different usage requirements and can be used to hang the infusion bottle. The outer sleeve plate 12 is vertically slidably connected to the side groove 4, and a lifting component is connected to the top of the outer sleeve plate 12. The middle part of the outer sleeve plate 12 is hollow, and an inner slide plate 13 is relatively slidably connected to the inner sleeve plate 12. Specifically, the inner slide plate 13 cannot be separated from the outer sleeve plate 12, and a spring 14 is elastically connected between the inner slide plate 13 and the outer sleeve plate 12, and a limiting component is connected to the outer end of the inner slide plate 13.

[0041] A vertical slot is provided in the middle of the inner wall of the two rotating slots 3, and a vertical slider 32 is vertically slidably connected in the two vertical slots. The two vertical sliders 32 are fixedly connected to the outer wall of one side of the threaded sleeve 7, specifically, the stability of the threaded sleeve 7 when it moves downward can be ensured. With the screw 6 and the threaded sleeve 7 being threadedly connected, they can slide under the weight of the suspension assembly and the infusion bottle, and drive the screw 6 to rotate, so that the threaded sleeve 7 can be stably lowered.

[0042] When the equipment is installed and needs to be used, the medical staff can first release the limit of the vertical displacement mechanism by the limit component, so that as the suspension component moves vertically downward along the screw 6 under the action of gravity, and as the screw 6 moves downward, it can be threadedly connected with the threaded sleeve 7, so that the threaded sleeve 7 can slide vertically along the side groove 4. The downward movement speed of the threaded sleeve 7 can be adjusted by relying on the abutment between the damping rubber and the screw 6. After sliding to the designated area, the patient or medical staff can use the limit component to limit it to ensure that the patient's infusion needs are met, and the required infusion bottle is hung on the suspension component, and the patient can receive normal infusion.

[0043] The limiting assembly includes a side plate 15, which is fixedly connected to the outer end of the inner slide plate 13, and a side slide bar 16 is connected to the side plate 15 for relative horizontal sliding sliding. A spring 18 is sleeved on the outer wall of one end of the side slide bar 16, and the spring 18 is elastically connected to the side plate 15 and one end of the side slide bar 16, and an insertion rod 17 is fixedly connected to the other end of the side slide bar 16.

[0044] The limiting assembly also includes a limiting plate 19, which is symmetrically fixedly connected to both sides of the shell 2. A rectangular round-shaped slot 20 is opened on the outer wall of the limiting plate 19, and a plurality of horizontal transverse slots 21 are evenly opened in the round-shaped slot 20. A socket 31 is opened on one side of the connection between the round-shaped slot 20 and the transverse slot 21.

[0045] Sliding slots 22 are provided above the multiple transverse slots 21, and blocking blocks 23 are connected to the multiple sliding slots 22 for relative horizontal sliding. The multiple blocking blocks 23 slide to the side away from the socket 31 and limit the circular slot 20. Specifically, the blocking blocks 23 of the corresponding height can be slid to the side away from the socket 31 as needed, thereby ensuring that the limit assembly can automatically return to its position and lock under the lifting assembly.

[0046] The depth of the insertion hole 31 is deeper than the circular notch 20 .

[0047] When the patient uses it for the first time, the medical staff needs to hold the side plate 15 and pull it outward to release the insertion limit connection between the insertion rod 17 and the insertion hole 31, and move the side slide bar 16 and the side plate 15 horizontally to drive the insertion rod 17 into the notch on the side of the circular groove 20 away from the insertion hole 31. At this time, multiple blocking blocks 23 are in the center position and do not cause obstruction at the circular groove 20; thus, the hanging assembly can quickly slide down to the appropriate position, which is convenient for medical staff or patients to hang the infusion bottle, and the patient can slide the blocking block 23 of the corresponding height to the other side according to his own needs to block the circular groove 20, so as to prevent the patient from sliding too high when using the lifting assembly later, affecting the patient's normal use.

[0048] After the infusion bottle is hung, the lifting assembly can be used to pull the hanging assembly upward, and when it slides to the corresponding transverse groove 21 area under the blocking of the blocking block 23, the spring 2 18 drives the insertion rod 17 in the unblocked state to slide along the transverse groove 21 to the current insertion hole 31 area, and under the elastic contraction of the two springs 1 14, the entire side plate 15 and the insertion rod 17 are pulled inward to slide, so that the insertion rod 17 is connected to the insertion hole 31, and the height of the infusion bottle is suspended.

[0049] When the patient needs to go out for activities, he only needs to repeat the above operation to conveniently take the infusion bottle, and after returning, he can use the lifting component to quickly put the infusion bottle back in place, and the operation can be completed with one hand.

[0050] The suspension assembly includes a rotating sleeve 8, which is rotatably connected to the top of the threaded sleeve 7, and the inner wall of the rotating sleeve 8 does not contact the screw rod 6. Specifically, the suspension assembly can be rotatably adjusted.

[0051] An outer rod 9 is fixedly connected to the outer end of the rotating sleeve block 8, and a slide groove is opened at the bottom end of the outer rod 9. An inner slide rod 10 is relatively slidably connected in the slide groove. A damping rubber is provided at the sliding connection between the inner slide rod 10 and the outer rod 9. Specifically, the stability of the outer rod 9 can be ensured under the damping rubber. A plurality of hanging hooks 11 are evenly and fixedly connected to the bottom end of the inner slide rod 10, and pressure sensors are provided at the plurality of hanging hooks 11. Specifically, the hanging hooks 11 can hang an infusion bottle, and when the weight of the infusion bottle is lower than the set threshold, the pressure sensor transmits a signal to the buzzer and warns the medical staff.

[0052] After the height adjustment is completed, the infusion bottle can be hung on the hanging hook 11 at the corresponding position according to the position situation, wherein the hanging hook 11 can be rotated around the center of the threaded sleeve block 7 and adjusted to a suitable position by utilizing the rotating connection between the rotating sleeve block 8 and the top of the threaded sleeve block 7, and can be adaptively slidably adjusted under the relative horizontal sliding connection between the inner slide rod 10 and the outer sleeve rod 9, so as to better meet the adjustment requirements of the infusion pressure of different drugs.

[0053] During the infusion operation, when the liquid in the infusion bottle gradually decreases over time, under the action of the pressure sensor, when the weight of the infusion bottle drops to the threshold, the buzzer will be connected and the corresponding signal will be transmitted to the medical staff. The buzzer can be directly sounded or the signal can be transmitted to the medical staff for adjustment. This can avoid the patient's health being endangered by the infusion bottle being empty and the infusion continuing due to physical discomfort and fatigue, etc., effectively improving the safety of the equipment and reducing the hidden dangers of infusion.

[0054] The lifting assembly includes a fixed wheel 1 25 rotatably connected to the movable cavity 5, and positioning plates 26 are symmetrically fixedly connected to the outer wall of the shell 2 on both sides. The bottom ends of the two positioning plates 26 are rotatably connected to fixed wheels 27, and the top ends of the two outer sleeve plates 12 are fixedly connected to connecting ropes 28. The two connecting ropes 28 are sequentially set with the fixed wheels 1 25 and the fixed wheels 27. Figure 8 The connecting rope 28 is sleeved outside the fixed wheel 1 25 and the fixed wheel 2 27 , and is rotationally connected to the fixed wheel 1 25 and the fixed wheel 2 27 .

[0055] The bottom ends of the two connecting ropes 28 are fixedly connected to pull rods 29, and the guide slides 24 are symmetrically fixedly connected to the outer wall of the back plate 1. The two guide slides 24 are relatively vertically slidably connected with positioning slides 30, and the outer ends of the two positioning slides 30 are fixedly connected to the connecting ropes 28.

[0056] A counterweight is arranged inside the pull rod 29 .

[0057] When the suspension assembly is adjusted to move downward, the pull rod 29 can be pulled vertically upward synchronously under the rotation connection between the fixed wheel 1 25 and the fixed wheel 27, wherein the pull rod 29 maintains its own stability under the vertical sliding of the positioning slide plate 30 and the guide slide plate 24. When it is necessary to move the suspension assembly upward, the blocking block 23 of the corresponding height is slid, and the circular notch 20 on the other side is blocked, and then the pull rod 29 is pulled downward by hand, and the corresponding area can be pulled under the connection of the connecting rope 28 by relying on the rotation connection between the fixed wheel 1 25 and the fixed wheel 27. The outer sleeve plate 12 of the domain slides vertically upward along the side slot 4 to the specified position, and when it slides to the corresponding transverse slot 21 area under the blocking of the manually sliding blocking block 23, the spring 2 18 drives the plug rod 17 in the unblocked state to slide along the transverse slot 21 to the current insertion hole 31 area, and under the elastic contraction of the two springs 1 14, the entire side plate 15 and the plug rod 17 are pulled inward to slide, so that the plug rod 17 is connected to the insertion hole 31, thereby completing the limitation of the suspension component and avoiding the displacement change of the suspension component under gravity.

[0058] In all the schemes mentioned above, the connection between the two parts can be selected according to the actual situation by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. Although the embodiments of the present invention have been shown and described, it can be understood by those of ordinary skill in the art that various changes, modifications, substitutions and deformations can be made to these embodiments without departing from the principle and spirit of the present invention.
