Description

Technical Field

[0001] The utility model belongs to the technical field of medical auxiliary equipment, and in particular relates to a drainage bottle height adjustment suspension device. Background Art

[0002] The height of the drainage bottle has a direct impact on the drainage rate and amount of drainage. By adjusting the height of the drainage bottle, the amount of cerebrospinal fluid or tissue fluid drained can be controlled to maintain normal intracranial pressure or other body cavity pressure. For example, in lumbar drainage care, the drainage tube orifice must be 3 to 4 cm above the level of the lumbar spinal canal, and the drainage bag must be below the level of the spinal canal to ensure smooth outflow of cerebrospinal fluid. When the patient changes position, from supine to semi-sitting, the height of the drainage tube orifice needs to be readjusted to maintain normal intracranial pressure.

[0003] Currently, drainage bottles are suspended using a bandage loop. Adjusting the height requires untying the bandage, adjusting the length, and then tying it again. This method is cumbersome and makes it difficult to accurately control the bandage length, which means the height of the drainage bottle cannot be accurately controlled. In other fields, some suspension devices use coil springs, but these springs rewind very quickly, making them dangerous to use. Utility Model Content

[0016] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings and embodiments.

[0017] In order to describe the technical scheme of the present application, the following will be described through specific embodiments.

[0018] As Figures 1-3 shown, the drainage bottle height adjustment suspension device provided by the embodiment comprises a bottom box 1 and a box cover 2, the top of the bottom box 1 is provided with a suspension part 3, a take-up wheel 4 and an operation wheel 5 are rotatably arranged in the bottom box 1, a hanging belt 6 is connected to the take-up wheel 4, and the hanging belt 6 is led out from the bottom of the bottom box 1, the bottom of the take-up wheel 4 is provided with a pinion 41, the operation wheel 5 comprises a support sleeve 51 and a large gear 52, the pinion 41 and the large gear 52 are engaged, the box cover 2 is provided with a locking mechanism 7 for locking the take-up wheel 4, and an operation handle 8 linked with the support sleeve.

[0019] The device is hung on a position-fixed suspender in a ward through the suspension part, and a hook is generally arranged at the bottom of the hanging belt, and the drainage bottle is hung on the hook during use. The device is characterized in that the take-up wheel and the operation wheel are arranged in the bottom box, the hanging belt is wound around the take-up wheel, and the box cover is further provided with the locking mechanism and the operation handle. The locking mechanism is used for locking the position of the take-up wheel, so as to avoid the take-up wheel from rotating and paying out the line when the drainage bottle is suspended. The operation wheel is used for engaging the large gear below with the pinion of the take-up wheel, and completing the winding through driving the operation wheel to rotate.

[0020] The structure design has the advantages that the operation wheel and the operation handle are separately arranged, and the automatic take-up of the coil spring is not used. There is no similar suspension device in the use occasion of the drainage bottle. In addition, the coil spring is generally used in the winding mode in other fields. However, the coil spring has the characteristic that the winding speed is very fast, similar to the winding of a tape measure, and the hook is arranged at the bottom of the hanging belt, and the coil spring winding mode has safety hazards in the ward. Therefore, the device adopts the manual winding mode, so as to ensure the safety.

[0021] Under the conventional mode, the operation handle is generally arranged on one side of the take-up wheel. However, since the take-up wheel rotates a large number of circles when paying out the line, the operation handle also needs to be reversely rotated a large number of circles when winding, which is relatively inconvenient. In the structure, the large gear is arranged to engage, so that a small number of circles of the large gear (that is, the operation handle is rotated) can drive the take-up wheel to rotate a large number of circles, so that the operation efficiency is improved.

[0022] In addition, in order to ensure the stability of the rotation of the two wheels, the center of the large gear 52 is provided with a first limiting hole 53, the center of the pinion 41 is provided with a second limiting hole 42, the bottom box 1 is provided with a positioning ring 11 matched with the first limiting hole 53 and a positioning column 12 matched with the second limiting hole 42. Therefore, the take-up wheel rotates around the positioning column, and the operation wheel rotates around the positioning ring. In addition, the bottom of the support sleeve 51 is provided with a pin shaft 54, the pin shaft 54 passes through the box cover 2 and is fixed with the operation handle 8. The operation handle can drive the operation wheel to rotate by being rotated.

[0023] As a specific structure of the locking mechanism, combined Figure 4As shown, the box cover 2 is provided with a through hole opposite the take-up wheel 4, the locking mechanism 7 comprises a top sleeve 71 above the through hole, the through hole is further provided with a matching compression ring 72, the compression ring 72 is laterally provided with a pressing plate 73, the pressing plate 73 is provided with a plurality of guide rods 74, the top sleeve 71 is provided with a circular hole 75 corresponding to the guide rods 74, the bottom of the compression ring 72 is provided with a ring of toothed openings 76, the top of the take-up wheel 4 is provided with a circular groove 43 opposite the position of the compression ring 72, the bottom of the circular groove 43 is provided with a ring of toothed grooves 44, the toothed openings 76 and the toothed grooves 44 are matched, the center of the top sleeve 71 is screwed into an adjusting hand rod 77, and the end of the adjusting hand rod 77 abuts against the pressing plate 73.

[0024] In the structure, the adjusting hand rod is first loosened, the compression ring keeps a certain pressure downward under the action force of the spring, and therefore the toothed openings at the bottom of the compression ring can keep the pressure on the toothed grooves. When the hanging belt is pulled out, the take-up wheel rotates, the compression ring slightly jumps during the rotation, and when the appropriate length is pulled out (the hanging belt is provided with a scale line), the position of the hanging belt is relatively stable and cannot be loosened under the limiting of the toothed openings and the toothed grooves. At this time, the adjusting hand rod is tightened so that the end is pressed against the pressing plate on the compression ring, and the locking of the take-up wheel is completed. In this way, the operation is simple, and the effect is good.

[0025] The above only describes preferred embodiments of the utility model and is not used to limit the utility model, and any modification, equivalent replacement and improvement made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
