Description

Technical Field

[0001] The invention relates to a drainage bag hook used in hospital clinics. Background Art

[0002] Currently, patients often require various drainage tubes to drain pus, blood, and fluids accumulated in body tissues or cavities to the outside of the body, preventing postoperative infection and impairing wound healing. Changes in patient position can cause traction on the drainage tube, and if the tube becomes dislodged, it can pose a risk or injury to the patient. Drainage bags are commonly used drainage devices, collecting pus, blood, and fluids removed by the drainage tube. Therefore, secure, proper, and reliable retention of the drainage bag is essential for safe tube care. Currently, a variety of devices are used to secure drainage bags, including adhesive tape, pins, hooks, bandages, and cotton ropes. These methods have significant drawbacks: Firstly, they offer limited reliability; secondly, they are inconvenient to attach and remove when the patient leaves bed. Furthermore, patients often forget to remove the drainage bag, causing the drainage tube to become dislodged due to traction.

[0003] For this reason, the applicant has developed a brand-new drainage bag fixing structure. Summary of the Invention

[0004] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide a drainage bag hook with a more reasonable structure, which can make it more convenient to hang the drainage bag and effectively avoid the risk of the drainage tube being pulled and falling off due to forgetting to remove the drainage bag when getting out of bed.

[0005] In order to solve the above-mentioned technical problems, the present invention adopts the following technical solutions:

[0006] A drainage bag hook comprises a hook seat, a hook arranged in a hook groove of the hook seat, and a knob for rotating the hook, wherein:

[0007] The hook slot of the hook seat includes a vertical slot, a horizontal slot and an outer oblique slot; an open elastic clip slot for clamping and installing the hook is provided on the upper part of the vertical slot;

[0008] The hook comprises a vertical hook portion, a horizontal hook portion and an oblique hook portion corresponding to the vertical slot, the horizontal slot and the outer oblique slot respectively; after the vertical hook portion of the hook is clamped into the elastic clamping slot, the hook can swing in and out of the horizontal slot and the outer oblique slot in the elastic clamping slot; a pair of clamping platforms are provided on the vertical hook portion, which are clamped outside the upper and lower ends of the elastic clamping slot; the oblique hook portion can elastically deform in the horizontal direction when subjected to external force and can automatically return to its original position when the external force is released;

[0009] The knob is arranged on the upper end of the vertical hook portion.

[0010] In an improved solution to the drainage bag hook, a trouser clip is provided on the knob, and the trouser clip and the horizontal hook portion and the oblique hook portion of the hook are respectively located on both sides of the vertical hook portion.

[0011] In the improved solution to the drainage bag hook, the horizontal hook portion and the oblique hook portion are integrally injection-molded with elastic plastic; the lower end of the vertical hook portion is tightly fitted with the horizontal hook portion.

[0012] In an improved solution to the drainage bag hook, the horizontal hook portion and the oblique hook portion are connected at their bends by an obtuse-angled spring piece.

[0013] In an improved solution to the drainage bag hook, a placement hole for placing a magnet is provided on the hook seat. After the magnet is placed in the placement hole, it is covered by a blocking cap.

[0014] In an improved solution to the drainage bag hook, strong adhesive paper is provided on the back of the hook seat.

[0015] Compared with the prior art, the present invention has the following advantages: since the vertical hook portion of the hook is inserted into the elastic clip groove, and the hook can swing in and out of the horizontal groove and the outer oblique groove in the elastic clip groove, it is convenient to store it when it is not needed; in addition, the oblique hook portion of the hook can be elastically deformed in the horizontal direction and automatically reset when subjected to external force, so that when the drainage bag is not removed and the range of activities beyond the length of the drainage tube is exceeded (such as going to the toilet, etc.), the drainage bag will be pulled. At this time, the oblique hook portion can be elastically deformed in the horizontal direction under a certain pulling force, so that the drainage bag can smoothly slide out along the oblique hook portion and fall to the ground, effectively reminding the patient or the patient The family members pick up the drainage bag in time, thereby avoiding the danger of the drainage tube being pulled and directly causing it to fall off; when the drainage bag slides out, the oblique hook part of the hook is automatically straightened and reset, so that it can continue to be used normally; at the same time, the hook can swing 180 degrees horizontally around the axis of the elastic clip groove, so that when the patient gets out of bed and moves, the pulling force at any angle can be consistent with the elastic deformation direction of the oblique hook, so that the drainage bag can smoothly slide out of the elastically deformed oblique hook when pulled at any angle. Therefore, the structure of the present invention is more reasonable, the drainage bag is easy to hang and take off, and it can effectively avoid the danger of pulling the drainage tube off due to forgetting to take off the drainage bag.

[0021] The present invention is a drainage bag hook, such as Figures 1 to 3 As shown, it includes a hook seat 1, a hook 2 arranged in a hook groove 11 of the hook seat 1, and a knob 3 for rotating the hook 2, wherein:

[0022] The hook slot 11 of the hook seat 1 includes a vertical slot 111, a horizontal slot 112 and an outer oblique slot 113; an open elastic clip slot 12 for clamping and installing the hook 2 is provided on the upper part of the vertical slot 111, which greatly facilitates the disassembly, replacement and maintenance of the hook;

[0023] The hook 2 includes a vertical hook portion 21, a horizontal hook portion 22, and an oblique hook portion 23 corresponding to the vertical slot 111, the horizontal slot 112, and the outer oblique slot 113, respectively. After the vertical hook portion 21 of the hook 2 is inserted into the elastic clip slot 12, the hook 2 can swing in and out of the horizontal slot 112 and the outer oblique slot 113 in the elastic clip slot 12. A pair of clamping platforms 211 are provided on the vertical hook portion 21, which are clamped outside the upper and lower ends of the elastic clip slot 12. This not only enhances the force applied to the hook, but also prevents the hook from falling out of the elastic clip slot in the vertical direction. The oblique hook portion 23 can elastically deform in the horizontal direction when subjected to external force and can automatically reset when the external force is released.

[0024] The knob 3 is provided at the upper end of the vertical hook portion 21 and is used for rotating the entire hook 2 to store the hook in the hook groove 11 of the hook seat 1 and to hang the drainage bag after the hook 2 is rotated out.

[0025] When the present invention is used, it is fixed to the side of the bed by means of strong adhesive tape or strong magnets, and then the knob 3 is rotated to swing out the horizontal hook portion 22 and the oblique hook portion 23 of the hook 2. Figure 2As shown, the drainage bag can be hung in this way; when the drainage bag is not needed, the knob 3 can be rotated to store the hook 2 in the hook groove 11 of the hook seat 1. When the patient leaves the bed and moves around without removing the drainage bag, the hook can swing horizontally 180 degrees around the axis of the elastic clip groove when it is gently pulled by the drainage tube. When the patient moves beyond the range of the drainage tube (such as going to the toilet), the drainage bag will be pulled so that the drainage bag slides from the horizontal hook portion 22 to the oblique hook portion 23. When the pulling force is relatively large, large enough to cause the oblique hook portion 23 to elastically deform in the horizontal direction, the drainage bag can smoothly slide out along the oblique hook portion and fall to the ground, thereby reminding the patient or the patient's family to pick up the drainage bag in time to avoid the risk of the drainage bag falling off. After the drainage bag slides out of the hook, the oblique hook portion 23 of the hook automatically straightens and resets, so that it can continue to be used normally. Therefore, the structure of the present invention is more reasonable, convenient for hanging and taking out the drainage bag, and can effectively avoid the risk of pulling the drainage tube off due to forgetting to remove the drainage bag.

[0026] The opening size of the elastic clip groove 12 should be convenient for disassembly and assembly of the hook 2 and can prevent the hook from falling out when hanging the drainage bag. Therefore, it must be smaller than 1 / 2 of the outer diameter of the vertical hook part 21, generally about 1 / 3 of the outer diameter of the vertical hook part 21.

[0027] Preferably, a waistband clip 4 is provided on the knob 3, and the horizontal hook portion 22 and the oblique hook portion 23 of the hook 3 are respectively on both sides of the vertical hook portion 21 (that is, equivalent to being 180 degrees apart). When the patient gets out of bed, the hook 2 can be pulled out of the elastic clip groove 12, and the waistband clip 4 can be used to clamp the patient's waistband or trouser pocket, etc., so that the drainage bag is in the lower position. In this way, the drainage effect of the patient is always guaranteed when he or she is moving at a long distance and for a long time, and the patient's hands are freed (because there is no need to carry the drainage bag by hand), so that the patient can get out of bed more flexibly and safely.

[0028] In order to allow the oblique hook portion 23 to elastically deform horizontally when subjected to external force and automatically reset when the external force is released, the hook can have different structures. For example, the cross hook portion 22 and the oblique hook portion 23 can be connected at the bend by a blunt-angled spring piece (whose cross-section is circular or elliptical to avoid cutting the ear of the drainage bag). In this embodiment, the cross hook portion 22 and the oblique hook portion 23 are integrally injection molded from elastic plastic. In actual production, according to the molding temperature and other measures, the hardness of the cross hook portion 22 can be made harder to withstand the weight of the fluid contained in the drainage bag, and the elasticity and hardness of the oblique hook portion 23 can be made to meet the requirements; the lower end of the vertical hook portion 21 is tightly fitted with the cross hook portion 22, such as Figure 4 shown.

[0029] In this embodiment, the knob 3, the vertical hook portion 21 and the waistband clip 4 are integrally formed by injection molding; of course, the vertical hook portion can be produced separately, while the knob 3 and the waistband clip 4 are integrally formed.

[0030] In this embodiment, the drainage bag hook is attracted to the side of the bed by a strong magnet. Figure 3 、 4 As shown, the hook base 1 is provided with a plurality of placement holes 13 for placing the magnets 5. After the magnets 5 are placed in the placement holes 13, they are covered by the plug caps 6. Of course, strong adhesive tape can also be provided on the back of the hook base 1 to stick the drainage bag hook to the side of the bed, just like the adhesive hooks commonly used at home.

[0031] In this embodiment, if Figure 3 As shown, the vertical groove 111 is a plane concave from the front side of the left side of the hook seat 1, which facilitates the production of the hook seat.

[0032] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications may be made to the present invention without departing from the principles and spirit of the invention as defined in the claims. Therefore, the detailed description of the disclosed embodiments is intended to be illustrative only and not to limit the present invention, which is to be defined by the claims.
