Description

Technical Field

[0001] The utility model relates to the technical field of nursing medical equipment, in particular to a drainage bag hook. Background Art

[0002] A drainage bag generally refers to a transparent plastic bag connected to the end of the drainage tube that is used to hold the drained liquid after surgery, where bleeding and fluid accumulation deep inside the body or in a local surgery need to be drained out using a pipe. For example, CN202022922738.7 discloses a drainage bag that is convenient for calculating drainage speed and flow rate. Although there are many structures of drainage bags in the prior art, this drainage bag retains the most common drainage bag structure, that is, it includes a bag body with a hanging ear, at least one drainage tube is provided on the bag body, and a drainage port is designed at the bottom of the bag body.

[0003] When the drainage bag is in use, it needs to be hung on the edge of the bed with a hook. When the patient needs to get up and move, the hook can also be hung in the buttonhole of the clothes. In the existing medical care process, there is no special hook for hanging the drainage bag. Generally, the drainage bag is fixed to the edge of the bed with a rope, or other simple 2-shaped hooks are used to hang the drainage bag.

[0004] In general, a patient only needs one drainage bag. However, in some cases, it may be necessary to drain body fluids from different locations. In order to prevent cross infection or facilitate operation, two drainage bags and two drainage tubes are often used for drainage. However, the existing hooks can only hang one drainage bag. When two drainage bags need to be hung, two independent hooks need to be used. It is very inconvenient to hang the hooks on buttonholes, and two hooks also need two hanging positions. Utility Model Content

[0005] The utility model aims to provide a drainage bag hook, which can use one main hook to hang two drainage bags, and can also adjust the position of the sub-hook according to the number of drainage bags hung. When in use, the force is balanced and deflection is not easy to find.

[0006] To achieve the above-mentioned purpose, an embodiment of the utility model provides a drainage bag hook, comprising a main hook, a crossbar installed at the lower end of the main hook, and two sub-hooks arranged on the crossbar;

[0007] A collar is sleeved on the crossbar, which is connected to the sub-hook, and a sealing cap is arranged at the end of the crossbar; the crossbar includes a limiting part and a sliding part, the outer diameter of the limiting part is larger than the sliding part, the outer side of the crossbar is provided with a limiting part, and the position where the crossbar is connected to the main hook is also provided with a limiting part;

[0008] The collar comprises an inner collar and an outer collar, the two ends of the inner collar form baffles, the middle of the inner collar forms an annular groove, and the outer collar is sleeved inside the annular groove; the inner diameter of the inner collar is larger than the sliding part, and the inner diameter of the inner collar forms an interference fit with the outer diameter of the limiting part;

[0009] The sub-hook is provided with an L-shaped bending portion bent inwardly at a position below the crossbar.

[0010] Preferably, in the utility model, a through hole is provided between the two limiting parts below the main hook, and a limiting sheet is provided after the lower part of the main hook passes through the through hole to prevent the main hook from escaping from the through hole.

[0011] Preferably, the sealing cap on the cross bar is a rubber plug, and the rubber plug is sleeved on the end of the cross bar.

[0012] Preferably, the length of the crossbar is 6 cm to 12 cm, the length of the main hook is 5 cm to 8 cm, and the length of the sub-hook is 6 cm to 9 cm.

[0013] In summary, the utility model has the following advantages:

[0014] 1. The utility model has two sub-hooks on the crossbar, the positions of which can be adjusted according to the number of drainage bags to be hung. The sub-hooks can be rotated on the crossbar through the rings, so that they can be kept in a vertical direction when hung at any hanging position, and are easier to combine with the drainage bag.

[0015] 2. The two sub-hooks of the utility model are bent inwards, so that the distance between the two sub-hooks is reduced when they are close together, making it easier to merge into one hook. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The utility model provides a drainage bag hook, comprising a main hook 1, a cross bar 2 installed at the lower end of the main hook 1, and two sub-hooks 3 arranged on the cross bar 2. The main hook 1 is used to hang the entire hook device in a suitable position, such as hanging it in a steel groove at the edge of the bed guardrail or edge of the hospital bed, or hanging it in a hole beside the bed. The function of the main hook 1 is the same as that of the semicircular hook at the upper end of the hook in the prior art. The cross bar 2 is used to install the sub-hooks 3. The cross bar 2 has a certain length and can provide a certain gap when hanging two drainage bags. The length of the cross bar 2 cannot be too long, otherwise it is easy to cause tilting, and it will also cause difficulty in hanging the main hook 1. The sub-hook 3 is a part used to hang the drainage bag. The tail structure of the sub-hook 3 can be similar to that of the main hook 1, so that the ear of the drainage bag can be hung on the sub-hook 3.

[0023] A collar is sleeved on the crossbar 2, and the collar is connected to the sub-hook 3. A cap 7 is provided at the end of the crossbar 2 to limit the collar on the crossbar 2 to prevent it from falling off. The cap 7 also has the function of sealing the end to prevent metal burrs from being exposed to the outside. The crossbar 2 includes a limiting portion 8 and a sliding portion 10. The outer diameter of the limiting portion is larger than that of the sliding portion 10. A limiting portion is provided on the outer side of the crossbar 2, and a limiting portion 9 is also provided at the position where the crossbar 2 is connected to the main hook 1.

[0024] The ring includes an inner ring 4 and an outer ring 5, the two ends of the inner ring 4 form baffles 6, the middle of the inner ring 4 forms an annular groove, and the outer ring 5 is sleeved inside the annular groove; the inner diameter of the inner ring 4 is larger than the sliding part 10, and the inner diameter of the inner ring 4 forms an interference fit with the outer diameter of the limiting part.

[0025] There is a certain movable gap between the outer ring 5 and the inner ring 4. The outer ring 5 can rotate outside the inner ring 4, and the baffle 6 of the inner ring 4 can limit the outer ring 5 in the annular groove 11 of the inner ring 4. The outer side of the crossbar 2 and the part combined with the main hook 1 are both provided with a limiting part. The inner diameter of the limiting part forms an interference fit with the inner diameter of the inner ring 4. This interference fit is similar to the fixing method of the telescopic fishing rod when it is extended, that is, the limiting part is not a cylindrical structure, but a structure similar to a truncated cone. The inner ring 4 first enters the end with a smaller inner diameter, and then the inner diameter of the limiting part gradually increases, so that the gap between the limiting part and the inner ring 4 gradually becomes smaller, and under the action of external force, the inner ring 4 can form an interference fit with the limiting part, and the inner ring 4 can no longer move, so it remains relatively fixed. When it is necessary to slide the inner ring 4, force is applied to rotate or slide in the opposite direction to make the inner ring 4 exit the limiting part. Due to the different fixing directions, the size of the limiting part on the outside of the crossbar 2 gradually decreases from the outside to the inside; the size of the limiting part near the bottom of the main hook 1 gradually increases from the direction away from the main hook 1 to the direction close to the main hook 1. In order to realize the installation of the collar, the collar and the limiting part on the main hook 1 can be separated, that is, a limiting part is integrally formed at the outer end of the crossbar 2, and a limiting part is formed below the main hook 1. When the collar is passed through the crossbar 2, the crossbar 2 can be fixed to the limiting part of the main hook 1 by screwing or welding.

[0026] The interference fit of the utility model means that a certain external force is required to allow the inner ring 4 to slide from the limiting portion. If there is no certain external force, the inner ring 4 will just be stuck on the limiting portion. The size of the sliding portion 10 is smaller than the inner ring 4, so the ring can slide freely on the sliding portion 10. The sub-hook 3 of the utility model is located below the cross bar 2 and is provided with an L-shaped bending portion that bends inward. The bending portion allows the two sub-hooks 3 to maintain a very small gap when they are closed in the middle, which is conducive to forming an integral hook.

[0027] When a drainage bag needs to be hung, the two sub-hooks 3 can be brought closer to the center. At this time, due to the existence of the bent portion 12, the lower parts of the two sub-hooks 3 can be combined into one hook, so that the ears of the drainage bag can be hung on the two sub-hooks 3 at the same time. At the same time, since the middle part of the cross bar 2 also has a limiting portion, the two sub-hooks 3 are also limited by the limiting portion after closing and cannot move at will, which has good stability.

[0028] When two drainage bags need to be hung, the two sub-hooks 3 can be moved outwards respectively. At this time, external force is required to make the two sub-hooks 3 reach the outer limiting parts and get stuck on the limiting parts, and then the drainage bags can be hung.

[0029] Preferably, a through hole 13 is provided between the two limiting parts below the main hook 1, and a limiting sheet 14 is provided after the lower part of the main hook 1 passes through the through hole to prevent the main hook 1 from being separated from the through hole. The two limiting parts below the main hook 1 can be an independent component, which can be called a limiting member. The limiting member can be an integral structure with two limiting parts at both ends, and the middle part is used to connect with the bottom of the main hook 1, for example, welding can be used to achieve a fixed connection, or a rotatable link can be achieved by using a through hole.

[0030] Preferably, the sealing cap 7 on the cross bar 2 is a rubber plug, which is sleeved on the end of the cross bar 2. The length of the cross bar 2 is 6cm to 12cm, the length of the main hook 1 is 5cm to 8cm, and the length of the sub-hook 3 is 6cm to 9cm.

[0031] Although the specific implementation of the utility model is described in detail in conjunction with the drawings, it should not be understood as limiting the scope of protection of this patent. Within the scope described in the claims, various modifications and variations that can be made by those skilled in the art without creative work still fall within the scope of protection of this patent.
