Description

Technical Field

[0001] This invention belongs to the technical field of nursing chairs, and specifically relates to a toilet assistance device. Background Technology

[0002] The number of cells in various systems of the human body is basically in dynamic equilibrium. If a group of cells in the body proliferates excessively under various tumorigenic factors, it will disrupt the stable state of cell regulation and form different types of tumors. Tumors must be treated, but patients are often weak after chemotherapy or surgery, especially in the late stages when they may develop cachexia, leading to a rapid decline in physical condition and swelling in the lower body. Some cancer patients may also experience frequent bowel movements due to intestinal dysfunction and drug side effects.

[0003] For frail cancer patients who are unable to squat when using the toilet, and who are prone to falls when using squat toilet facilities, special nursing chairs are provided in clinical care to improve the quality and efficiency of cancer patient care.

[0004] The Chinese patent, authorized by CN201847843U and entitled "A Wheelchair for the Disabled," allows the user to use the toilet. Before using the toilet, a push bar helps the user stand up to facilitate taking off their pants. However, for severely weakened cancer patients, even with assistive devices, standing is very difficult. Furthermore, if medical staff or family members help the patient take off / put on their pants, it can easily cause the patient to experience embarrassment or other negative emotions.

Detailed Implementation

[0033] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0034] Please see Figure 1 and Figure 2 In one embodiment, a toilet assistance device includes: a wheelchair frame 1, a seat tilting assembly 2, a seat sliding assembly 3, and a clamping assembly 4.

[0035] In one embodiment, the wheelchair frame 1 is provided with a seat 11 for the patient to sit on. The seat 11 includes a seat frame 111 and a seat body 112. The seat body 112 is slidably installed in the seat frame 111 and slides on the wheelchair frame 1. One end of the seat frame 111 is hinged to the wheelchair frame 1.

[0036] The wheelchair frame 1 also includes a first support frame 12, a second support frame 13, a backrest 14, and armrests 15. There are two first support frames 12 arranged symmetrically, and two second support frames 13 arranged symmetrically; the first support frames 12 and the second support frames 13 are connected by support rods 17. When the seat 11 is horizontal, the seat 11 is perpendicular to both the first support frames 12 and the second support frames 13. One end of the seat frame 111 is hinged to the first support frame 12, and the seat frame 111 rotates around the hinge point. Two sets of armrests 15 are provided, respectively installed on both sides of the seat frame 111. The backrest 14 is installed on the second support frame 13.

[0037] The wheelchair frame 1 also includes a walking mechanism 16, which has multiple sets and is respectively installed at the bottom of the first support frame 12 and the second support frame 13. Preferably, the walking mechanism 16 adopts existing technology, such as a tire-type walking method, and the wheelchair frame 1 has walking and steering functions under the drive of external force or self-power. This structure facilitates the movement of the wheelchair frame 1 to a suitable position.

[0038] In one embodiment, the seat tilting assembly 2 is mounted on the wheelchair frame 1, and the output end of the seat tilting assembly 2 is connected to the seat frame 111. The seat tilting assembly 2 drives the seat frame 112 to tilt relative to the horizontal plane. Preferably, the output end of the seat tilting assembly 2 is connected to the lower end face of the seat frame 111 near the backrest 14.

[0039] The seat tilting assembly 2 includes a first drive source 22 and a guide assembly 21. Two sets of the first drive source 22 are mounted on two second support frames 13, respectively. The output end of the first drive source 22 is connected to the seat frame 111. The guide assembly 21 is mounted on the wheelchair frame 1 and is used to limit the angle at which the first drive source 22 drives the seat frame 111 to tilt relative to the horizontal plane.

[0040] Preferably, the first drive source 22 is a cylinder. In order not to affect the movement of the wheelchair frame 1 to the toilet, the cylinder is installed on the end face of the second support frame 13 that is close to the first support frame 12.

[0041] Please see Figure 5 and Figure 6Specifically, the guide assembly 21 has multiple sets, including a spring pin 211, a rotating shaft 212, and a rotating wheel 213. The spring pin 211 is fixedly mounted on the seat frame 111, and its elastic top end has a groove 214. The rotating shaft 212 is rotatably mounted in the groove 214, and the rotating wheel 213 is mounted on the rotating shaft 212, with the rotating wheel 213 protruding outside the spring pin 211. The backrest 14 has a guide groove 141 corresponding to the rotating wheel 213. The rotating wheel 213 extends into the guide groove 141 and abuts against the inner wall of the guide groove 141, sliding along the guide groove 141. Thus, the length of the guide groove 141 limits the angle of rotation of the seat frame 111. When the rotating wheel 213 is at its lowest position in the guide groove 141, the seat frame 111 is parallel to the horizontal plane. When the rotating wheel 213 is at the highest position of the guide groove 141, the seat frame 111 is at its maximum tilt angle with the horizontal plane. The seat frame 111 lifts the patient, and the patient's thighs are separated from the seat body 112. Only part of the buttocks is in contact with the seat body 112. At this time, external force is most likely to take off or put on the patient's pants.

[0042] In use, the first drive source 22 is activated, and its output end extends upward, driving the seat frame 111 to rotate upward along the hinge. The extension and retraction of the spring pin 211 adjusts the distance between the seat frame 111 and the backrest 14, ensuring that the rotating wheel 213 always contacts the inner wall of the guide groove 141. The seat frame 111 slides along the guide groove 141. When the rotating wheel 213 reaches the highest position of the guide groove 141, the first drive source 22 stops extending, the seat frame 111 stops rotating, and its angle of inclination with the horizontal plane is at its maximum. Activating the first drive source 22 again causes its output end to retract. When the rotating wheel 213 reaches the lowest position of the guide groove 141, the seat frame 111 is in a horizontal position, and the patient sits flat on the seat 111.

[0043] Please see Figure 3 , Figure 4 , Figure 7 and Figure 8 The seat sliding assembly 3 is installed on the wheelchair frame 1 and is connected to the seat body 112. The seat sliding assembly 3 is used to drive the seat body 112 to slide and switch positions between the wheelchair frame 1 and the seat frame 111 to close or open the toilet space.

[0044] The seat sliding assembly 3 has two sets, which are respectively connected to the two sides of the seat body 112. The seat sliding assembly 3 includes a drive assembly 32, which is connected to the seat body 112. The first support frame 12 and the seat frame 111 are provided with a connected slide groove 121. The drive assembly 32 drives the seat body 112 to move along the slide groove 121.

[0045] Specifically, the drive assembly 32 includes a second drive source 321, a worm gear 322, a worm 323, a lead screw 324, a slider 325, and a connecting rod 326. The second drive source 321 is mounted on the first support frame 12, and its output end is connected to the worm 323. The worm 323 meshes with the worm gear 322. The lead screw 324 is rotatably mounted on the first support frame 12 and is mounted on the axis of the worm gear 322. The slider 325 is threadedly connected to the outside of the lead screw 324. One end of the connecting rod 326 is hinged to the slider 325, and the other end of the connecting rod 326 passes through the outside of the first support frame 12 and is hinged to the side surface of the seat plate body 112. Preferably, the second drive source 321 is a motor. Preferably, the first support frame 12 has an equipment cavity 122, in which a worm gear 322 and a worm 323 are installed, and a lead screw 324 and a slider 325 are installed in a slide groove 121, which communicates with the equipment cavity 122. The slide groove 121 is divided into a first slide groove section 124 and a second slide groove section 123. The first slide groove section 124 is located in the first support frame 12, and the second slide groove section 123 is located in the seat plate frame 111. Both the first slide groove section 124 and the second slide groove section 123 have arc-shaped slide groove sections at their joints. The lead screw 324 and the slider 325 are installed in the first slide groove section 124, and the other end of the connecting rod 326 passes through the first slide groove section 124 and is hinged to the side surface of the seat plate body 112.

[0046] A pulley 31 is provided on the side wall of the seat plate body 112, and the pulley 31 is connected to the seat plate body 112 via a drive shaft 33. The drive shaft 33 is rotatably mounted on the side of the seat plate body 112. The pulley 31 is mounted on one end of the drive shaft 33, and the other end of the drive shaft 33 passes through the slide groove 121 and is mounted on the side of the seat plate body 112.

[0047] Preferably, the seat plate body 112 is a split type, consisting of multiple sub-seat plate bodies. Adjacent sub-seat plate bodies are hinged to each other on both sides by connecting plates 113, and the connecting rod 326 is hinged to the side surface of the first sub-seat plate body.

[0048] like Figure 7 As shown, when the seat frame 111 has its maximum inclination angle with the horizontal plane, the first slide section 124 and the second slide section 123 arc-shaped slide sections match, and the joint between the two has sufficient width for the pulley to pass through. Figure 8 As shown, when the seat frame 111 is at other angles to the horizontal plane, the overlap gap between the arc-shaped slide grooves of the first slide groove section 124 and the second slide groove section 123 decreases, and the pulley 31 cannot pass smoothly.

[0049] In use, the first drive source 22 is activated. When the seat frame 111 reaches its maximum tilt angle with the horizontal plane, the second drive source 321 is activated, driving the worm gear 322 to rotate, which in turn drives the lead screw 324 to rotate. The slider 325 moves up and down along the lead screw 324, and the connecting rod 326 moves along the first sliding groove section 124. The connecting rod 326 pushes the seat body 112 to move, thereby causing the pulley 31 to move along the sliding groove 121, that is, the seat body 112 slides between the first support frame 12 and the seat frame 111. When the seat body 112 is between the two sets of first support frames 12, the toilet entrance space is opened; when the seat body 112 is on the seat frame 111, the toilet entrance space is closed.

[0050] In one embodiment, a clamping assembly 4, mounted on the seat plate body 112, is used to clamp the patient's trousers and allows the trousers to be put on or taken off as the seat plate body 112 moves. The clamping assembly 4 includes a chain 41 and a clip 42. One end of the chain 41 is connected to the seat plate body 112, and the other end is connected to the clip 42. Preferably, one end of the chain 41 is connected to a sub-seat plate body near the backrest 14. When the seat plate body 112 slides from the seat frame 111 to the first support frame 12, the clamping assembly 4 moves downwards with the seat plate body 112, thereby removing the patient's trousers. When the seat plate body 112 slides from the first support frame 12 to the seat frame 111, the clamping assembly 4 moves upwards with the seat plate body 112, thereby assisting the patient in putting on their trousers.

[0051] In one embodiment, the seat tilting assembly 2 drives the seat frame 111 to tilt. For patient safety, the device is equipped with a safety belt 5, which is mounted on the armrests 15. The safety belt 5 includes a first safety belt body 51, a buckle 52, a second safety belt body 53, and a buckle 54. One end of the first safety belt body 51 is provided with the buckle 52; one end of the second safety belt body 53 is provided with the buckle 54, and the buckle 52 is detachably inserted into the buckle 54. The other ends of the first safety belt body 51 and the second safety belt body 53 are respectively connected to the armrests 15 on both sides. Specifically, the other end of the first safety belt body 51 is connected to one set of armrests 15; the other end of the second safety belt body 53 is connected to another set of armrests 15. Preferably, to accommodate patients of different body shapes, the first safety belt body 51 is elastic.

[0052] When in use, the patient sits on the wheelchair frame 1, and the first safety belt body 51 and the second safety belt body 53 are wrapped around the patient's waist. The buckle 52 is inserted into the buckle 54 to secure the patient.

[0053] The specific use of this invention is as follows: When a patient needs to use the toilet, external force is used to assist the patient in sitting on the seat 11 and fastening the seat belt 5. The walking mechanism 16 is used to control the wheelchair's movement, slowly bringing it closer to the toilet and positioning it appropriately. The first drive source 22 is activated, driving one end of the seat frame 111 upwards while the other end rotates around the hinge until the seat frame 111 stops rising. The patient's trousers are secured with clips 42. The second drive source 321 is activated, driving the seat body 112 to move along the slide 121 until it is positioned between the two first support frames 12. During this movement, the clips 42 cause the trousers to move downwards, allowing them to be removed. The patient's buttocks contact the sides of the seat frame 111, and simultaneously, the seat body 112 moves downwards, exposing the toilet space. The first drive source 22 is activated again, causing the patient to slowly lower down, and the seat frame 111 returns to its original position, remaining horizontal. The patient can then use the toilet while sitting on the seat frame 111. After the patient finishes using the toilet, the first drive source 22 is activated, causing one end of the seat frame 111 to move upwards, putting the seat frame 111 in an inclined state. The second drive source 321 is then activated, causing the seat body 112 to move along the slide groove 121. The clip 42 then moves the pants upwards, allowing the patient to put them on. Activating the first drive source 22 returns the seat frame 111 to a horizontal position, and the seat body 112 closes the toilet space. The clip 42 can then be removed from the pants. This allows the patient to use the toilet independently without the assistance of caregivers, reducing the burden on caregivers or family members and avoiding embarrassment or other negative emotions for the patient.

[0054] The beneficial effects of this invention are:

[0055] The aforementioned toilet assistance device comprises a seat 11, a seat tilting assembly 2, a seat sliding assembly 3, and a clamping assembly 4 mounted on a wheelchair frame 1. The seat 11 includes a seat frame 111 and a seat body 112 slidably mounted on the seat frame 111. The seat tilting assembly 2 drives the seat frame 112 to tilt relative to the horizontal plane.
