Abstract
Description
Technical Field
[0001] This invention relates to the field of toilet technology, specifically to a toilet for mental patients with a safety protection structure. Background Technology
[0002] Toilets are an indispensable sanitary appliance in modern bathrooms. They are usually made of materials such as ceramics and have a well-designed seat and bowl structure, allowing people to sit comfortably on them to defecate. Their unique internal flushing system can use water flow to quickly flush away excrement and discharge it into the sewer. Some toilets also have a variety of functions such as water saving, intelligent flushing, and warm air drying, which greatly improves the convenience and hygiene of use and brings many conveniences to daily life.
[0003] In the unique context of mental illness treatment and care, traditional toilets often fail to meet safety and protection needs, prompting the development of specialized toilets for mental patients. Due to the nature of their illness, mental patients are often emotionally unstable. When in a state of agitation, their behavior is uncontrollable; they may grab nearby objects and throw or vandalize them, potentially turning parts of a regular toilet into weapons. Furthermore, some mental patients may suddenly have an episode while using the toilet, engaging in extreme behaviors such as retrieving feces from the toilet and attacking medical staff. This not only seriously threatens the personal safety of medical personnel but also poses significant hygiene risks and adverse effects on the entire medical environment. Existing ordinary toilets lack effective protective designs against the specific behaviors of mental patients and cannot effectively cope with such emergencies. Therefore, developing a toilet specifically designed for mental patients with multiple safety protection functions is particularly necessary and urgent. This is of great significance for ensuring the safety of medical staff, maintaining medical order, and improving the quality of care for mental patients. Summary of the Invention

[0039] This invention provides a toilet for mental patients with a safety protection structure. Compared with the prior art, it has the following advantages:
[0040] 1. This toilet for mental patients, equipped with a safety protection structure, features a seat mounted on top of the toilet with a built-in sliding flexible curtain. In the event of a mental patient's agitation or outburst, potentially involving the throwing of feces, the flexible curtain can be pushed to quickly close the passageway, effectively sealing the top of the toilet. During normal use, the flexible curtain can be opened without affecting functionality. Simultaneously, a restraint mechanism is installed on the seat. If the patient exhibits signs of agitation, the restraint mechanism can be quickly activated and retracted, using restraint straps to bind the patient's upper body to the main body, preventing the patient from standing and facilitating further control by medical personnel. The overall solution is novel and effectively addresses the issue of potential outbursts in mental patients.
[0041] 2. This toilet for mental patients with a safety protection structure features a two-way restraint component. A round-headed rotating rod is inserted into the restraint strap. Utilizing the unidirectional deflection property of the rotating rod, the restraint strap can bend smoothly without restriction when pulled out. Once pulled out and restrained by the rotating rod, it will not spring back. The elastic rotation setting of the rotating rod also allows it to automatically return to a vertical position. When restraint is needed, simply controlling the servo motor to rotate the rotating base and its rotating rod 180° instantly switches the deflection direction, causing the restraint strap to lose its restraining force and spring back. It also restricts reverse pull-out, ensuring that once the restraint strap is used to bind a mentally unstable patient, it cannot be loosened, achieving a good restraint effect. The control method is also quite convenient.
[0042] 3. This toilet for mental patients with a safety protection structure uses a connecting rope to string together several curtains to form a flexible curtain. On the one hand, it retains its rigidity and is not easily damaged under the constraint of the main body's inner cavity; on the other hand, it retains its flexibility, allowing it to bend and slide along the curvature of the main body. Moreover, only one end of the flexible curtain needs to be pushed by the drive mechanism to make the whole curtain slide, which is convenient to drive. The design with gaps inside the flexible curtain also facilitates flushing and drainage.
[0043] 4. This toilet for mental patients with a safety protection structure features a soft pillow at the head position on the seat, with an additional removable headrest on the outside. The combination of the two pillows provides good protection, preventing the patient's head from hitting their hands when they become agitated or manic. The outer headrest is easy to remove and clean regularly, and can also be wiped with water for easy hygiene maintenance. The four corners of the headrest can be fixed with a single adhesive, making it easy to operate. Attached Figure Description

[0063] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0064] See Figures 1-10 This invention discloses a toilet for mental patients with a safety protection structure, and provides the following four technical solutions:
[0065] The first embodiment includes a toilet 1 and a seat 2 mounted on it. The seat 2 includes a main body 21 and armrests 23 fixedly connected to both sides. A gap needs to be maintained between the bottom of the main body 21 and the toilet 1 to facilitate the flushing of the flexible curtain 4 from the bottom. Chair legs 22 are fixedly connected and bolted to the ground. A through groove is provided in the middle of the seat portion of the main body 21 for toilet use. The interior of the main body 21 is equipped with a flexible curtain 4 that can be opened or closed by covering or opening the through groove. A drive mechanism 5 for sliding the flexible curtain 4 is installed on the back of the main body 21. The top two sides of the board are rotatably connected to flip-up cushions 3, and the opposite surfaces of the two flip-up cushions 3 are shaped to fit the through groove. The flip-up cushions 3 are made of plastic, which is not too cold to the touch compared to the metal seat 2. In winter, foam toilet seat covers can be attached to the flip-up cushions 3 to insulate against the cold and prevent patients from being stimulated by the cold flip-up cushions 3. The left and right flip-up method is adopted instead of the traditional direct flip-up, which can prevent patients from being uncomfortable when leaning back after using the toilet. The main body 21 and the armrest 23 are also equipped with restraint mechanisms 7, which are used to restrain the upper body when the mental patient is agitated.
[0066] The constraint mechanism 7 includes:
[0067] The R-shaped bracket 71 is fixedly connected to the top front side of the handrail 23. The R-shaped design of the R-shaped bracket 71 is that the vertical sections of its two corners are inserted into the handrail 23 for fixation, and the slanted section is fixed on the front slanted surface of the handrail 23. The slanted surface makes the restraint strap 72 tend to slide upward to the top. The inverted U-shaped part at the top of the R-shaped bracket 71 can block the restraint strap 72 so that it will not slip off the R-shaped bracket 71. When it is necessary to restrain and retract the restraint strap 72, simply pull the restraint strap 72 up so that it passes over the R-shaped bracket 71.
[0068] The winding restriction mechanism 74 is fixedly connected to the left and right sides of the rear side of the main body 21;
[0069] The restraint strap 72 is fixedly connected at both ends to two sets of winding restriction mechanisms 74, and the middle section of the restraint strap 72 is hung on the R-type bracket 71 when it is not tightened.
[0070] The winding restriction mechanism 74 is used to wind up the constraint tape 72, and the winding restriction mechanism 74 is provided with a bidirectional restriction component 747 for passing through and unidirectionally restricting the constraint tape 72, and the locking direction of the bidirectional restriction component 747 is variable.
[0071] The roll-out restriction mechanism 74 also includes:
[0072] The base 741 is fixedly connected to the rear side of the main body 21;
[0073] The outer casing 742 is fixedly connected to the rear side of the base 741 by bolts;
[0074] The take-up drum 743 is rotatably connected inside the housing 742, and the end of the restraint band 72 is fixedly connected to the take-up drum 743. A through hole for the restraint band 72 to pass through is provided on one side of the housing 742.
[0075] The mainspring barrel 744 is fixedly connected to the top of the outer casing 742, and the center of the mainspring inside the mainspring barrel 744 is connected to the central axis of the winding drum 743 to drive the winding drum 743 to rotate.
[0076] The wheel frame 745 is fixedly connected to the rear side of the base 741, and the inner side of the wheel frame 745 is rotatably connected to the pulley 746, and the restraint belt 72 is laid on the pulley 746.
[0077] The bidirectional limiting assembly 747 is installed on the inside of the wheel frame 745 and is integrally fixed to the base 741 by bolts.
[0078] This application proposes a novel solution by installing a seat 2 on a toilet 1, with a sliding flexible curtain 4 built into the seat 2. When a mentally ill patient becomes agitated and may throw feces, the flexible curtain 4 can be pushed to quickly close the passageway, thus sealing the top of the toilet 1. During normal use, the flexible curtain 4 can be opened without affecting its operation. Simultaneously, a restraint mechanism 7 is installed on the seat 2. When the patient exhibits signs of agitation, the restraint mechanism 7 can be quickly activated and retracted, using restraint straps 72 to bind the patient's upper body to the main body 21, preventing the patient from getting up and facilitating further control by medical personnel. The overall solution is novel and effectively addresses the issue of potential episodes in mentally ill patients.
[0079] The second implementation differs from the first implementation mainly in that the bidirectional limiting component 747 includes:
[0080] Motor box 7471, which contains a servo motor;
[0081] Rotary seat 7472 is fixedly connected to the output shaft of the servo motor;
[0082] The rotating insert 7473 is rotatably connected to the rotating seat 7472 via a shaft perpendicular to the axis of the rotating seat 7472, and the rotating seat 7472 has a notch on one side adapted to the rotating insert 7473 to limit the unidirectional deflection of the rotating insert 7473;
[0083] The elastic straightening structure 7474 coaxially connects the rotating seat 7472 and the rotating rod 7473, and uses elasticity to keep the rotating seat 7472 and the rotating rod 7473 coaxial;
[0084] Several metal rings 73, which are adapted to the rotating insert rods 74 and 73, are evenly and fixedly connected to the constraint band 72.
[0085] The bidirectional restraint component 747 uses a round-headed rotating rod 7473 inserted into the restraint band 72. Utilizing the unidirectional deflection property of the rotating rod 7473, the restraint band 72 can smoothly bend the rotating rod 7473 without restriction when pulled out. After being pulled out and restrained by the rotating rod 7473, it will not spring back. The elastic rotation setting of the rotating rod 7473 also allows it to automatically rotate back to vertical. When restraint is needed, simply controlling the servo motor to rotate the rotating seat 7472 and its rotating rod 7473 180° instantly switches the deflection direction, causing the restraint band 72 to lose its restraining force and spring back, while also preventing reverse pull-out. This ensures that once the restraint band 72 is tied to a mentally unstable patient, it cannot be loosened, achieving a good restraint effect, and the control method is relatively convenient.
[0086] The third embodiment differs from the first embodiment in that: the flexible curtain 4 is composed of several curtain slats 41 arranged side by side, and the curtain slats 41 are connected together by a connecting rope 42. The main body 21 has a cavity inside that matches the thickness of the flexible curtain 4. A groove can also be opened on the front bottom of the main body 21 to facilitate the sliding out of the flexible curtain 4. After the flexible curtain 4 is separated from the push rod 55, it can slide out from the front for replacement or thorough cleaning. The drive mechanism 5 includes:
[0087] The protective sleeve 51 is longitudinally fixed to the middle of the rear side of the main body 21 by bolts;
[0088] The servo motor 52 is fixedly connected to the bottom of the sleeve 51 and to the rear side of the main body 21 by bolts. The servo motor 52 with appropriate torque is selected so that the flexible curtain 4 pushed will not squeeze or injure the patient's arm when the patient's hand has passed through the main body 21.
[0089] The lead screw 53 is rotatably connected inside the sleeve 51, and the bottom end of the lead screw 53 is fixedly connected to the output shaft of the servo motor 52.
[0090] Threaded sleeve 54, the thread is sleeved on the outside of lead screw 53;
[0091] The push rod 55 is fixedly connected to both sides of the threaded sleeve 54, and the end of the push rod 55 away from the threaded sleeve 54 extends forward and passes through the rear wall of the main body 21, and is inserted into the topmost strip 41. A groove 211 adapted to the push rod 55 is provided on the rear side of the main body 21.
[0092] The controller 9 is fixedly connected to the rear side of the main body 21, and the controller 9 is electrically connected to the servo motor and the servo motor 52 through wires. The controller 9 has a built-in wireless receiving module for wireless control, and a start button is provided at the bottom of the controller 9.
[0093] The flexible curtain 4 is constructed by connecting several curtain strips 41 in series with connecting rope 42. On the one hand, it retains its rigidity and is not easily damaged under the constraint of the inner cavity of the main body 21. On the other hand, it retains its flexibility, so that it can bend and slide along the curvature of the main body 21. Moreover, only one end of the flexible curtain 4 needs to be pushed by the drive mechanism 5 to make it slide as a whole, which is convenient to drive. The design of the gap inside the flexible curtain 4 also facilitates washing and drainage.
[0094] The fourth embodiment differs from the first embodiment in that: the backrest of the main body 21 has an opening at the top front side, and a soft pillow 8 is pasted inside the opening; a headrest 6 can also be detachably installed on the top of the backrest of the main body 21, and the headrest 6 covers the soft pillow 8.
[0095] Headrest 6 includes:
[0096] Soft pad 61, the surface of soft pad 61 is made of waterproof and washable fabric;
[0097] Vertical straps 62 are sewn to both sides of the rear end of the padding 61;
[0098] The horizontal straps 63 are sewn to the lower left and right corners of the pad 61, and the two horizontal straps 63 are wrapped around the back of the main body 21 and glued to each other with Velcro. The ends of the vertical straps 62 are loops that are fitted onto the horizontal straps 63.
[0099] Positioning sleeves 212 are fixedly connected to both the left and right sides of the rear side of the main body 21, and horizontal straps 63 are installed through the positioning sleeves 212.
[0100] By placing a soft pillow 8 at the head position of the seat 2, and adding a detachable headrest 6 on the outside of the soft pillow 8, the combination of the two pillows provides good protection and can prevent the head of the mental patient from hitting the hand when the patient is agitated and manic. The outer headrest 6 is easy to remove and clean regularly, and can also be wiped with water for easy maintenance. The four corners of the headrest 6 can be fixed at the same time with just one glue, which is convenient to operate.
[0101] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0102] When using it, for mental patients with unstable daily emotions, first pull up the restraint strap 72, then let the patient sit on the flip-up cushion 3 to use the toilet, and then pull the restraint strap 72 to the R-shaped brackets 71 hanging on both sides in front of the body. At this time, metal rings 73 will be put on the rotating plugs 7473, thus preventing the restraint strap 72 from rebounding.
[0103] When a patient suddenly becomes angry, medical staff must first hold the patient down in seat 2 to prevent them from getting up. Then, they press the button at the bottom of controller 9 to start the servo motor 52, which drives the lead screw 53 to rotate. This, in turn, drives the threaded sleeve 54 and push rod 55 to descend, pushing the flexible curtain 4 downward until the front of the flexible curtain 4 covers the through groove of the main body 21. At the same time, the servo motor drives the rotating seat 7472 and the rotating insert 7473 to rotate 180°. At this time, the locking direction of the rotating insert 7473 changes, and the spring box 744 rebounds, driving the winding drum 743 to rotate and winding up the restraint strap 72. During this process, the restraint strap 72 will push the rotating insert 7473 to deflect and fall down. After tightening, the patient struggles forward, pulling out a section of the restraint strap 72, causing the nearby metal ring 73 to move to the rotating insert 7473. The rotating insert 7473 straightens under the elastic tension of the elastic straightening structure 7474 and inserts into the metal ring 73, thereby locking the restraint strap 72.
