Description

Technical Field

[0001] This utility model relates to the technical field of bedside toilets, specifically a toilet for installation on a nursing bed. Background Technology

[0002] Some hospitalized patients or those still in the recovery period after discharge are unable to stand or walk due to their condition, and therefore can only lie down or sit in bed for short periods. For these patients, defecation can only be completed in bed. Current technology often uses urinals or nursing pads to allow patients to defecate in bed, but using these methods results in lower patient cooperation due to the supine position, and also easily leads to excrement staining the sheets and blankets. Existing technology also includes nursing beds that can facilitate defecation, such as a multi-functional nursing bed with publication number CN113476242B; however, this technology requires changes to the bed frame structure and cannot be installed on existing ordinary nursing beds. Therefore, in practical use, the original nursing bed needs to be replaced, which is costly and not conducive to widespread adoption. Utility Model Content

[0003] The present invention aims to at least partially solve one of the technical problems in the related art: to provide a commode for installation on a nursing bed, which can be installed on an existing nursing bed so that the patient can sit by the bed to defecate, thus avoiding the patient having to stand or walk, and allowing the patient to defecate in a sitting position. At the same time, the defecation process is located by the bed, so it is not easy to cause soiling of the bed sheets and blankets.

[0004] Therefore, one objective of this utility model is to provide a commode for installation on a nursing bed. It includes an annular seat cushion with a mounting bracket at its rear end. One end of the mounting bracket is fixedly connected to the rear end of the seat cushion, and the other end of the mounting bracket has a connecting seat for connecting to the nursing bed frame. The seat cushion is equipped with a heating component for heating the seat cushion. The mounting bracket is connected to the existing nursing bed frame via the connecting seat, allowing the seat cushion fixed to the other end of the mounting bracket to be suspended beside the nursing bed. This allows the patient to sit up from the nursing bed and move to sit on the seat cushion without needing to stand or walk. Furthermore, the patient remains seated during defecation, consistent with the posture of sitting on a toilet, resulting in high patient acceptance. Additionally, since the commode is located beside the bed, simply pulling aside the portion of the sheets and blankets near the commode reduces soiling of the sheets and blankets, especially when small amounts of excrement leak out, which drips downwards, significantly reducing soiling of one side of the nursing bed.

[0005] Preferably, one end of the mounting bracket is provided with a mounting plate, which fits against the bottom surface of the rear end of the seat cushion, and the mounting plate is fixedly connected to the rear end of the seat cushion by a locking screw.

[0006] Preferably, the connecting seat includes a turntable and a support disc. One side of the turntable is fixed to the mounting bracket. The turntable has a central hole. The support disc is located below the turntable, and a vertical connecting shaft is provided on the center line of the support disc. The lower end of the connecting shaft is fixed to the support disc, and the upper end of the connecting shaft passes through the central hole on the turntable axially. The end of the connecting shaft exposed above the turntable has a threaded joint for connecting the nursing bed frame. A planar bearing is provided between the turntable and the support disc, and between the turntable and the nursing bed frame.

[0007] Preferably, the heating component includes a graphene heating element built into the seat cushion, with electrodes of the graphene heating element extending outside the seat cushion for connection to an external power source. The graphene heating element heats the seat cushion, allowing it to be at a comfortable temperature for the patient.

[0008] Preferably, the top of the outer surface of the seat cushion has a contact surface for supporting the patient, and the graphene heating element is a graphene fiber cloth located inside the seat cushion and arranged below the contact surface. The graphene fiber cloth has an electrode, one end of which is electrically connected to the graphene fiber cloth, and the other end of which extends outside the seat cushion. The portion of the electrode located outside the seat cushion forms a terminal for connecting to an external power source.

[0009] Preferably, the seat cushion is made of fiberglass, and the graphene fiber cloth and the seat cushion are an integral structure.

[0010] Preferably, the thickness h1 between the graphene fiber cloth and the contact surface on the seat cushion is 0.5~1mm, and the thickness h2 between the graphene fiber cloth and the lower surface of the seat cushion opposite to the contact surface is 2~5mm. A thinner thickness h1 is beneficial to improving the thermal conductivity between the graphene fiber cloth and the seat cushion, while a thicker thickness h2 can improve the heat insulation effect and reduce the heat loss from the lower surface generated by the graphene fiber cloth, that is, reduce the heat transfer between the graphene fiber cloth and the lower surface.

[0011] The above technical solution has the following advantages or beneficial effects: First, by installing the bracket, the seat cushion can be installed on the existing nursing bed frame, allowing the patient to sit on the seat cushion at the bedside to complete the defecation process. During this process, the patient does not need to stand and walk to the toilet to defecate, and can adopt a comfortable sitting posture. At the same time, the seat cushion is located at the bedside of the nursing bed, reducing the probability of excrement soiling the sheets and duvet covers during defecation. Second, the connecting seat has a rotating function, so the seat cushion can be rotated out when needed for the patient to sit and defecate. After defecation, it can be rotated inward to complete the storage of the seat cushion. Finally, the seat cushion is made of fiberglass, and graphene fiber cloth is pre-fabricated inside the fiberglass during the manufacturing process. Therefore, when the built-in graphene fiber cloth is powered on, it can evenly heat the entire contact surface of the seat cushion in a surface heating manner, making the temperature comfortable for the patient to sit on the seat cushion, especially in scenarios where the external ambient temperature is low.

[0012] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0021] The following describes in detail, with reference to the accompanying drawings, a commode for mounting on a nursing bed according to an embodiment of the present invention.

[0022] This utility model provides a toilet seat for installation on a nursing bed, as shown in the figure. It includes an annular seat ring 1, and a mounting bracket 2 is provided at the rear end of the seat ring 1. One end of the mounting bracket 2 is fixedly connected to the rear end of the seat ring 1, and the other end of the mounting bracket 2 is provided with a connecting seat 4 for connecting to the nursing bed frame 6. The seat ring 1 is provided with a heating component for heating the seat ring 1.

[0023] Preferably, one end of the mounting bracket 2 is provided with a mounting piece 3, which is in contact with the bottom surface of the rear end of the seat cushion 1, and the mounting piece 3 is fixedly connected to the rear end of the seat cushion 1 by a locking screw.

[0024] Based on one of the preferred examples of the connector 4 in the above embodiments: The connecting seat 4 is a slider, and the nursing bed frame 6 is equipped with a slide rail that matches the slider. The slide rail is fixedly installed on the nursing bed frame 6, and the slider slides onto the slide rail. This allows the seat cushion 1 and the mounting bracket 2 to be hidden in the bed space under the bed board as the slider slides horizontally, or to be pulled out horizontally and located on one side of the nursing bed. This sliding engagement structure of the slider and slide rail is a conventional sliding and translation mechanism, and its structure will not be described in detail here.

[0025] Based on the preferred embodiment of the connecting seat 4 in the above embodiments, the following is a second example: The connecting seat 4 includes a rotating shaft and a bushing. The bushing is fitted over the rotating shaft and rotates in cooperation with it. The upper end of the rotating shaft is fixed to the bed frame 6 of the nursing bed, and the rotating shaft has a limiting nut to restrict the axial movement of the bushing. The end of the mounting bracket 2 facing away from the seat cushion 1 is fixedly connected to the bushing. In this embodiment, both the rotating shaft and the bushing are commercially available products. The mounting bracket 2, through the rotational cooperation between the bushing and the rotating shaft, allows the mounting bracket 2 and the seat cushion 1 on the mounting bracket 2 to rotate around the rotating shaft, thereby rotating to the bottom of the nursing bed to hide and store the seat cushion 1, or driving the seat cushion 1 to one side of the nursing bed for the patient to sit on the seat cushion 1 beside the bed to relieve themselves.

[0026] Based on the preferred embodiment of the connecting seat 4 in the above embodiments, the third preferred example is as follows: like Figure 3and Figure 5 As shown, the connecting seat 4 includes a turntable 4.1 and a support disc 4.3. One side of the turntable 4.1 is fixed to the mounting bracket 2. The turntable 4.1 has a central hole 4.1.1. The support disc 4.3 is located below the turntable 4.1, and a vertical connecting shaft 4.4 is provided on the center line of the support disc 4.3. The lower end of the connecting shaft 4.4 is fixed to the support disc 4.3, and the upper end of the connecting shaft 4.4 passes axially through the central hole 4.1.1 on the turntable 4.4. The end of the connecting shaft 4.4 exposed above the turntable 4.1 has a threaded joint 4.4.1 for connecting the nursing bed frame 6. A plane bearing 4.2 is provided between the turntable 4.1 and the support disc 4.3, and between the turntable 4.1 and the nursing bed frame 6. The connecting seat 4 with this structure has a higher torque than the above-mentioned method of using a bushing around the turntable, so that the support disc 4.3 can provide greater support force to the turntable 4.1 when the patient sits on the seat cushion 1.

[0027] It should be understood that, in actual use, a basin or bucket for catching the patient's excrement can be placed under the seat cushion 1. A soluble stool bag can be placed inside the basin or bucket, allowing the soluble stool bag to be disposed of after catching the patient's excrement. Furthermore, although the two sides of the turntable 4.1 rotate with the mounting bracket 2 during the rotation of the seat cushion 1, and are respectively connected to the supporting disc 4.3 and the nursing bed frame 6 via planar bearings 4.2, these planar bearings 4.2 should possess a certain degree of frictional resistance, also known as frictional damping. This frictional resistance allows the seat cushion 1 to maintain its current position under the action of frictional resistance without being subjected to additional force. The patient or caregiver can apply a horizontal pushing force to the seat cushion 1 to rotate it around the connecting shaft 4.4, and after the pushing force is removed, the seat cushion 1 can maintain its current position under the action of frictional damping.

[0028] Based on the preferred embodiment of the heating component described above, the heating component includes a graphene heating element 5 built into the seat cushion 1, with electrodes of the graphene heating element 5 extending outwards from the seat cushion 1 for connection to an external power source. Specifically, the electrodes of the graphene heating element 5 extend from the bottom of the rear end of the seat cushion 1 to the outside of the seat cushion 1, and the portion of the electrode outside the seat cushion 1 is connected to an electrical connector via a wire, which is then electrically connected to an external power source. Of course, a switch for switching the power on and off can also be provided on this wire.

[0029] Furthermore, the top of the outer surface of the seat cushion 1 has a contact surface 1.1 for supporting the patient. The graphene heating element 5 is a graphene fiber cloth located inside the seat cushion 1 and arranged below the contact surface 1.1. The graphene fiber cloth has an electrode, one end of which is electrically connected to the graphene fiber cloth, and the other end of which extends outside the seat cushion 1. The portion of the electrode located outside the seat cushion 1 forms an electrical connector for connecting to an external power source.

[0030] Specifically, the seat cushion 1 is made of fiberglass, which refers to glass fibers coated with resin. After the resin cures, it combines with the glass fibers to form fiberglass. The graphene fiber cloth is prepared within the fiberglass during the fiberglass manufacturing process, making the graphene fiber cloth and seat cushion 1 an integral structure. In this embodiment, the graphene fiber cloth refers to a graphene film formed on ordinary fiber cloth. This graphene film has a heating function when electricity is applied, hence the fiber cloth is called graphene heating fiber cloth, or simply graphene fiber cloth. This graphene fiber cloth is a conventional commercially available product in the graphene field, therefore, its structure will not be described in detail in this embodiment.

[0031] like Figure 6 As shown, the thickness h1 between the graphene fiber cloth and the contact surface 1.1 on the seat cushion 1 is 0.5~1mm, and the thickness h2 between the graphene fiber cloth and the lower surface of the seat cushion 1 opposite to the contact surface 1.1 is 2~5mm. The heat generated by the graphene fiber cloth after being energized is surface heating, which means that the entire contact surface 1.1 can be heated evenly. The larger thickness between the graphene fiber cloth and the lower surface can play a role in heat preservation and improve heat utilization; while the smaller thickness between the graphene fiber cloth and the contact surface 1.1 results in better thermal conductivity between the graphene fiber cloth and the contact surface 1.1.

[0032] In the above embodiments, the heating power of the graphene fiber cloth should be such that the temperature on the contact surface 1.1 meets the human body's perceived temperature. Preferably, when the graphene fiber cloth is electrically heated, the temperature on the contact surface 1.1 is 20~25℃. In this embodiment, the heating power of the graphene fiber cloth can be obtained through a limited number of experiments; therefore, the current and voltage required for heating the graphene fiber cloth are not described in detail in this embodiment.

[0033] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.

[0034] For those skilled in the art, various changes and modifications will undoubtedly be apparent after reading the above description. Therefore, the appended claims should be considered as covering all changes and modifications that encompass the true intent and scope of this utility model. Any and all equivalent scope and content within the scope of the claims should be considered as still falling within the intent and scope of this utility model.
