Description

Technical Field

[0001] This utility model relates to the technical field of negative pressure drainage auxiliary equipment, and in particular to a fixed pillow for a negative pressure drainage device. Background Technology

[0002] Negative pressure drainage devices typically include a drainage conduit and a negative pressure drainage corrugated container connected to the drainage conduit. For example, Chinese patent document CN201821993905.3, authorized and published on October 11, 2019, discloses a negative pressure drainage device that, from top to bottom, includes a drainage conduit, a negative pressure drainage corrugated container connected to the drainage conduit, and a fixed base that is fitted and connected to the negative pressure drainage corrugated container. For example, in Chinese patent literature, patent number CN202221030827.3, authorized and announced on August 9, 2022, describes a negative pressure drainage device that facilitates drainage. This application includes a circular top plate and a circular bottom plate, with a corrugated compression-type liquid collection chamber between the circular top plate and the circular bottom plate. A liquid outlet hole is opened in the middle of the bottom of the circular bottom plate, and a circular base is provided at the bottom of the circular bottom plate. A rectangular through groove is opened at the bottom of the circular base, and a rectangular solid block is provided in the middle of the rectangular through groove. A drainage hole a is opened in the middle of the top of the rectangular solid block, and a rectangular connecting through groove is opened on the front side of the rectangular solid block. A slidable strip movable plate is provided in the rectangular through groove, and one end of the strip movable plate is inserted into the rectangular connecting through groove for sliding connection.

[0003] Existing negative pressure drainage devices utilize a corrugated container secured by a fixed base or circular base at its bottom. However, this method requires installation within an external structure, necessitating a fixed platform outside the bed. This is both inconvenient and prone to safety hazards. Furthermore, conventional negative pressure drainage devices typically have the patient holding onto the edge of the bed, requiring constant vigilance to prevent the container from falling, causing significant psychological stress and hindering recovery. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings of the prior art, this utility model provides a fixed pillow for a negative pressure drainage device, which can conveniently limit the negative pressure drainage device on the hospital bed, making it convenient for patients to rest.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] A fixing pillow for a negative pressure drainage device, the negative pressure drainage device includes a corrugated effusion bottle, the fixing pillow limits the corrugated effusion bottle on the hospital bed, the fixing pillow includes a connecting part and a fixing part, the connecting part is locked between the bed rail and the bed frame, and the fixing part, after being locked by the connecting part, has a accommodating space relative to the bed frame for limiting the corrugated effusion bottle, and the lower side of the fixing part used to form the accommodating space is elastic.

[0007] The fixed pillow in this application is installed between the bed railing and the bed frame via a connecting part, making it convenient to place at the edge of the bed without requiring structural modifications to the bed or adding external fixing structures, thus offering high versatility. The corrugated effusion bottle, with its space-limiting design, eliminates the need for patient support, reducing psychological burden and ensuring patient rest. When used with the negative pressure drainage device, the corrugated effusion bottle expands from a flat state along the corrugated axis. The lower side of the fixing part is elastic, providing elastic pressure to the outside of the corrugated effusion bottle, ensuring its expansion capacity and reliably completing negative pressure suction and effusion.

[0008] Preferably, the outer surface of the fixation part is elastic. The outer surface of the fixation part, which lies above the hospital bed, is elastic, ensuring safety and comfort for the patient should they accidentally bump into or press on the fixation part, without causing pain.

[0009] Preferably, the connecting part is elastic. This elasticity allows for easy and secure clamping between the bed railing and the bed frame, and also provides a degree of elastic deformation, making the pressure exerted on the corrugated effusion bottle by the fixing part more flexible and avoiding negative impacts on its operation.

[0010] Preferably, the fixation pillow includes a cloth cover and a pillow core made of sponge or silicone. The fixation pillow is easy to manufacture and shape. It is elastic and highly deformable, easily adapting to the volume expansion of corrugated infusion bottles, and will not disturb the patient's rest in bed.

[0011] Preferably, the cross-sectional shape of the fixing pillow is "L"-shaped, with the connecting part and the fixing part located at opposite ends of the "L". The fixing part is more easily deformable than the connecting part, effectively avoiding interference with the use of the corrugated liquid bottle while ensuring that the fixing part limits the position of the corrugated liquid bottle.

[0012] Preferably, the fixing part is connected to the lower edge of the connecting part, which is higher than the upper end of the guardrail. When the fixing part is subjected to lateral pressure, it will act on the connecting part. This size setting can avoid the guardrail interfering with the deformation of the connecting part, ensure the fitting deformation capability of the connecting part, and allow the outer end of the fixing part to flip upward.

[0013] Preferably, the end of the connecting part away from the fixing part has a bevel to form a wedge angle between the bed frame and the guardrail. This facilitates the locking of the connecting part between the guardrail and the bed frame.

[0014] Preferably, a transition section is provided at the junction of the inner sides of the fixing part and the connecting part, and the transition section is a chamfer or a rounded corner. The transition section strengthens the connection between the fixing part and the connecting part and provides a smoother guide, allowing the corrugated liquid bottle to expand outward along the transition section when expanding along the corrugation axis, further reducing the negative impact of the fixing part on the use of the corrugated liquid bottle.

[0015] Preferably, the inclined surface intersects with the transition section. Even if the connecting part is not fully inserted, the corrugated liquid bottle can first engage with the inclined surface and then expand along the transition section, further reducing the negative impact of the fixing part on the expansion and use of the corrugated liquid bottle.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this utility model are intended to cover non-exclusive inclusion, such as a method or product that includes a series of technical features, not limited to those technical features explicitly listed, but also including other technical features that may be included in the method or product but not explicitly listed.

[0024] In the description of this utility model, it should be understood that the technical features defined by terms such as "first" and "second" which have a sequential concept are only for the purpose of clearly describing the defined technical features and making the defined technical features clearly distinguishable from other technical features, and do not represent that they are named in this way in actual implementation. Therefore, they should not be construed as limitations on this utility model.

[0025] One embodiment of this utility model discloses a fixing pillow for a negative pressure drainage device, such as... Figures 1 to 5 As shown, the negative pressure drainage device includes a corrugated effusion bottle 1, and a fixed pillow on the hospital bed to limit the corrugated effusion bottle 1. The fixed pillow includes a connecting part 3 and a fixing part 4. The connecting part 3 is locked between the bed rail 7 and the bed frame. After the connecting part 3 is locked, the fixing part 4 has a accommodating space 5 relative to the bed frame for limiting the corrugated effusion bottle 1. The lower side of the fixing part 4 used to form the accommodating space 5 is elastic.

[0026] The existing hospital bed includes a bed frame, a bed board 6, and guardrails 7. The bed board 6 is mounted on the bed frame. The guardrails 7 are foldable and typically located at both ends of the width direction along the length of the bed frame. The guardrails 7 can be folded onto the upper side of the bed frame. A mattress 8 is mounted on the bed board 6. The mattress 8 and the bed board 6 form the bed body. There are gaps between the guardrails 7, the bed board 6, and the mattress 8. The connecting part 3 can be inserted into the gaps and locked in place. The bed frame is not shown in the figure. Since the hospital bed is existing technology and not an improvement of this application, the specific structure will not be elaborated. The negative pressure drainage device includes a corrugated effusion bottle 1 and a drainage tube 2. The corrugated effusion bottle 1 is initially flat. During application, the corrugated effusion bottle 1 expands under external force, forming an internal negative pressure, which is used to achieve negative pressure drainage of the patient's effusion. Figure 2 As shown, the corrugated effusion bottle 1 is concealed within the accommodating space 5, effectively limiting its position at the edge of the bed without requiring the patient's assistance. When the negative pressure drainage device is used, the corrugated effusion bottle 1 expands axially, allowing for adjustments such as... Figure 4The proposed solution moves the corrugated effusion bottle 1 a certain distance inward into the bed, reducing the impact of the fixing part 4 on its use. The fixing pillow in this application is secured between the bed rail 7 and the bed frame via the connecting part 3, allowing for convenient placement at the bed edge without requiring structural modifications to the bed or adding external fixing structures, thus offering high versatility. The corrugated effusion bottle 1 is contained by the accommodating space 5, eliminating the need for patient support, reducing psychological burden, and ensuring patient rest. When the negative pressure drainage device is used, the corrugated effusion bottle 1 expands from a flat state along the corrugated axis. The lower side of the fixing part 4 is elastic, providing elastic pressure to the outside of the corrugated effusion bottle 1, ensuring its expansion capacity and reliably completing negative pressure suction and effusion.

[0027] In the prior art, guardrails are also provided at both ends of the length of the hospital bed. This utility model is a simple replacement for the above-mentioned solution of setting a fixed pillow on the side of the bed. The fixed pillow is set between the head guardrail and the bed body or between the foot guardrail and the bed body.

[0028] As one embodiment of this utility model, a fixing pillow for a negative pressure drainage device is disclosed, such as Figures 1 to 4 As shown, the negative pressure drainage device includes a corrugated effusion bottle 1, and a fixed pillow on the hospital bed to limit the corrugated effusion bottle 1. The fixed pillow includes a connecting part 3 and a fixing part 4. The connecting part 3 is locked between the bed rail 7 and the bed frame. After the connecting part 3 is locked, the fixing part 4 has a accommodating space 5 relative to the bed frame for limiting the corrugated effusion bottle 1. The lower side of the fixing part 4 used to form the accommodating space 5 is elastic.

[0029] In this embodiment, the connecting part 3 and the fixing part 4 of the fixed pillow are arranged vertically so that the cross-sectional shape of the fixed pillow is "L" shaped, with the connecting part 3 and the fixing part 4 corresponding to the two ends of the "L" shape respectively. The fixed pillow disclosed in this embodiment includes a cloth cover and a pillow core made of sponge or silicone. The fixed pillow is easy to manufacture and shape. The fixed pillow as a whole is elastic and has strong deformation ability, which is convenient to accommodate the volume expansion of the corrugated effusion bottle 1, and will not affect the patient's rest on the hospital bed. The outer surface of the fixing part 4 is elastic. This makes it safer and more comfortable for the patient if they accidentally touch or press on the fixing part 4, without causing the patient pain. The connecting part 3 is elastic. On the one hand, it can be easily and elastically squeezed between the bed rail 7 and the bed frame. On the other hand, the connecting part 3 can have a certain elastic deformation ability, making the pressure of the fixing part 4 on the corrugated effusion bottle 1 more elastic, avoiding negative impact on the operation of the corrugated effusion bottle 1.

[0030] Furthermore, when the corrugated liquid bottle 1 is equipped with a bottom outlet tube, the outlet tube can run from the lower side of the connecting part 3. The elasticity of the connecting part 3 will not compress the outlet tube, and the connecting part 3 can also improve the elastic limiting effect of the outlet tube.

[0031] Furthermore, such as Figure 2 As shown, the fixing part 4 is connected to the lower edge of the connecting part 3, which is higher than the upper end of the guardrail 7. If the patient or nurse forgets to move the corrugated effusion bottle 1 a certain distance out of the receiving space 5, the corrugated effusion bottle 1 expands axially and pushes upward, causing the connecting part 3 to deform at the position of the guardrail 7, and the fixing part 4 flips upward. Figure 3 As shown, it will not affect the expansion and use of the corrugated liquid collection bottle 1.

[0032] In this embodiment, the end of the connecting part 3 away from the fixing part 4 is provided with a bevel 31 to form a wedge between the bed body and the guardrail 7. A transition part 41 with rounded corners is provided at the junction of the inner sides of the fixing part 4 and the connecting part 3. The bevel 31 intersects with the transition part 41. Even if the connecting part 3 is not fully inserted, the corrugated liquid bottle 1 can first engage with the bevel 31, and then expand along the transition part 41, further reducing the negative impact of the fixing part 4 on the expansion of the corrugated liquid bottle 1.

[0033] In the above embodiments, the edges of the fixing part 4 are all provided with transition rounded corners, which can provide patients with a better application experience.

[0034] As another embodiment of this utility model, the fixed pillow is as follows: Figure 5 As shown, the only difference from the previous embodiment is that the edge of the fixing part 4 is not provided with a transition rounded corner. The outer end of the fixing part 4 serves as a warning through a right-angle structure to prevent the patient from pressing on the corrugated effusion bottle 1. The negative pressure drainage device has high safety.
