Description

Technical Field

[0001] This invention relates to the field of nursing device technology, specifically to an intelligent nursing device for psychiatric nursing and its usage method. Background Technology

[0002] The focus of psychiatric nursing management is safety care. The significance of safety care lies in ensuring the personal safety of psychiatric patients and medical staff. It is not only an important indicator of the quality of psychiatric nursing, but also an important part of patient care, and the primary task of psychiatric nursing.

[0003] Nursing care during psychiatric medication administration and routine physical examinations are two crucial aspects of clinical psychiatric nursing. Routine physical examinations allow for regular monitoring of the patient's emotional and physical condition, assisting physicians in providing more precise treatment. Many psychiatric patients do not acknowledge their illness and exhibit negative attitudes, frequently refusing medication, leaving medication unattended, or hiding medication. Therefore, nurses often employ patient persuasion as an intervention method. However, patients with psychiatric illnesses may exhibit unpredictable and resistant behaviors, creating difficulties for healthcare workers. Therefore, appropriate intelligent nursing devices are needed to assist medical staff in the administration of medication and routine nursing examinations.

[0004] According to a nursing chair for psychiatric patients published in CN213722977U, a positioning device is provided to stabilize and fix the patient's upper limbs, allowing the chair body to adjust and fix the upper limbs of different patients, thereby improving the comfort of patient fixation and reducing the workload of nursing staff. The invention has a simple overall structure, is highly practical, and is easy to promote and use.

[0005] The current method uses two sets of fixing straps and elastic straps to restrict the patient's movement. It requires manual operation by staff to complete the restraint, and multiple people are needed to cooperate during the operation. When psychiatric patients resist strongly, directly restraining their hands and feet can easily cause the nursing chair to shake and become unstable. At the same time, even after the hands and feet are restrained, patients can still resist by pushing off the ground with their feet, which affects the use of the nursing chair and, consequently, the doctor's ability to alleviate the patient's emotions and provide treatment and care. Therefore, we propose an intelligent nursing device for psychiatric nursing and its usage method. Summary of the Invention

[0006] The purpose of this invention is to provide an intelligent nursing device for psychiatric care and its method of use, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an intelligent nursing device for psychiatric care, comprising a seat, a backrest, armrests, and a limiting seat; the top of the seat is provided with an anti-slip mat; a backrest is fixed to one side of the seat; and armrests are fixed to the side edges of the seat and the backrest.

[0008] Connecting frames are fixed to the two sides of the top of the backrest. A flip frame is rotatably sleeved on the upper side of the connecting frame. Cantilever arms are fixed to both ends of the flip frame. A player speaker is fixed to the side of the cantilever arm. A display screen is rotatably connected to the end of the cantilever arm away from the flip frame.

[0009] The seat has a limiting seat on the side away from the backrest to restrict the sitting posture. The upper side of the anti-slip pad has symmetrical fastening plates to restrict swaying. The upper edge of the limiting seat has symmetrical notches. A pressure sensor is embedded in the notch of the limiting seat. The inside of the limiting seat has a storage cavity. A locking ring is provided in the middle of the storage cavity. A rack is fixed to the outer side of the locking ring.

[0010] The limiting seat is provided with a drive mechanism for adjusting the reciprocating rotation of the locking ring in the middle. The drive mechanism includes a drive motor, a driving bevel gear, a driven bevel gear, a universal joint, a slanted turntable, a limiting sleeve, and a spiral strip. The drive motor is installed at the bottom of the limiting seat. The output end of the drive motor is fixed with a driving bevel gear. One side of the driving bevel gear is meshed with a driven bevel gear. The two sides of the driven bevel gear are connected to the slanted turntable through universal joints. The surface of the slanted turntable is fixed with a spiral strip that meshes with a rack.

[0011] Preferably, the surface of the limiting seat is provided with a through hole for the inclined turntable to reciprocate, the outer edge of the inclined turntable is provided with an annular protrusion, and the annular protrusion is slidably connected with the limiting sleeve, and the limiting sleeve is installed in the through hole on the surface of the limiting seat.

[0012] Preferably, the surface of the anti-slip mat has two sets of parallel guide grooves, the bottom support of the fastening clamp is inserted from the upper side of the guide groove, the bottom of the support of the fastening clamp is also fixed with a movable plate, the surface of the seat near the anti-slip mat has a sliding groove for the movable plate to dock, and a return spring is connected between the movable plate and the sliding groove.

[0013] Preferably, each of the two sets of inclined turntables has convex tooth blocks distributed at equal angles on adjacent sides, the convex tooth blocks meshing with the transmission gear, and the transmission gear has a central shaft fixed in the middle.

[0014] Preferably, one end of the central shaft of the transmission gear is movably connected to a bearing on the surface of the limiting seat, the other end of the central shaft of the transmission gear is fixed to a winding wheel, the surface of the winding wheel is fixed to one end of the wire rope, the other end of the wire rope is fixed to a moving plate, and the length of the wire rope is greater than the distance from the winding wheel to the moving plate.

[0015] Preferably, the drive motor is fitted with a bottom protective shell, the limiting seat is provided with a side protective shell one on the side near the anti-slip pad, and the limiting seat is provided with a side protective shell two on the side away from the anti-slip pad. The lower sides of the side protective shell one and the side protective shell two are fixed with connecting ears. The bottom protective shell is fastened to the connecting ears of the side protective shell one and the side protective shell two with screws. The two sides of the bottom protective shell are installed to the bottom of the limiting seat with screws.

[0016] Preferably, the limiting seat has slide rails on both sides, and a T-shaped block is fixed to the inner wall of the seat near the limiting seat. The slide rails and the T-shaped block are slidably connected. The bottom of the limiting seat is symmetrically connected to a reserved cylinder through a movable seat. The lower end of the reserved cylinder is movably connected to the upper surface of the fixed frame.

[0017] Preferably, a fixing frame is fixed to the lower side of the seat, a belt conveyor is provided inside the fixing frame, a support plate is fixed between the fixing frames, and a weighing sensor is fixed to both sides of the support plate.

[0018] Preferably, the top of the weighing sensor is connected to a mounting base, and a support roller is connected between the two mounting bases.

[0019] A method for using an intelligent nursing device for psychiatric care includes the following steps:

[0020] S1: The limit seat is pulled down by the cylinder until its top is flush with the upper side of the anti-slip pad;

[0021] S2: By rotating the flip frame around the connecting frame, the cantilever is flattened and the display screen is placed in front of the patient. The display screen and the speaker are used to divert the patient's attention and alleviate the patient's resistance.

[0022] S3: When a psychiatric patient is sitting in a chair for a nursing examination, the limiting seat is pushed up by a cylinder and the notch of the limiting seat is used to separate the patient's two legs.

[0023] S4: When the limit seat rises to the point where the pressure sensor senses contact with the patient's leg, the locking ring is opened and locked by controlling the drive mechanism, thereby restricting the patient's sitting posture and automatically restricting the patient's resistance movements by limiting the legs.

[0024] S5: When the locking ring flips and restricts the patient's leg movement, the winding wheel winds and winds the steel wire rope, thereby simultaneously pulling the two sets of binding splints to restrict the patient's upper body, thus reinforcing the upper body against the patient's resistance movements.

[0025] S6: Use straps to restrain the patient's hands to the handrails and use instruments to perform routine nursing checks on the patient's body.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: The intelligent nursing device for psychiatric care and its method of use, through the operation of the drive mechanism, causes the inclined turntable to rotate and unfold the locking ring via the spiral strip, thereby locking the thigh of the psychiatric patient, achieving automatic restriction of the patient's legs. Furthermore, the forward-rotating inclined turntable drives the convex tooth block to mesh with the transmission gear, causing the winding wheel to wind and wind the steel wire rope, and driving two sets of binding clamps to clamp and restrain the upper body of the psychiatric patient on both sides, reducing the shaking caused by the patient's resistance. Then, the belt conveyor with a weighing sensor relieves the force for the patient who wants to stand up, ensuring that the intelligent nursing device achieves efficient restraint when treating psychiatric patients, and reducing the workload of doctors in restraining patients.

[0027] 1. This invention controls a drive motor to drive two sets of slanted turntables to rotate symmetrically and synchronously. When the slanted turntables rotate forward, the spiral strips on their surfaces mesh with the racks on the outside of the locking ring. The continuously rotating spiral strips can push the locking ring out along the opening of the receiving cavity, causing the locking ring to flip and unfold at the recess of the limiting seat and lock the thigh of the psychiatric patient. This restricts the patient's sitting posture and prevents the patient from standing up, thus achieving automatic leg restraint of the patient's resistance movements. This eliminates the need for medical staff to perform tedious leg restraint multiple times, thereby saving manpower.

[0028] 2. When the nursing device of the present invention is in use, the forward-rotating inclined turntable drives the convex tooth block to mesh with the transmission gear, so that the central shaft of the transmission gear drives the winding wheel to wind and wind the steel wire rope. When the locking ring completes the restriction on the legs, the continuous winding of the steel wire rope by the winding wheel can drive the two sets of moving plates to move closer to each other, so that the two sets of moving plates respectively drive the binding clamp to clamp and restrain the upper body of the psychiatric patient on both sides, thereby strengthening the upper body to prevent swaying of the patient's resistance movements.

[0029] 3. This invention uses an extended cylinder to push the limiting seat upward, causing the slide rails on both sides of the limiting seat to slide along the T-shaped block inside the seat. This allows the two notches on the upper side of the limiting seat to grip the patient's thigh from bottom to top. When the limiting seat rises to the point where the pressure sensor senses contact with the patient's leg, the pressure sensor transmits a signal to the matching PLC controller, causing the PLC controller to stop the cylinder. Thus, the patient will not be affected by the limiting seat while sitting in the seat, preventing any stimulation to the patient.

[0030] 4. This invention combines a limiting seat with a drive mechanism to restrain psychiatric patients on the seat of the nursing device. When the patient's foot steps on the belt conveyor, the weighing sensor senses the downward supporting force of the mounting seat and support roller. When the value sensed by the weighing sensor is large, the belt conveyor is controlled to rotate forward, causing the transmission belt to rotate away from the seat. Thus, when the patient steps on the belt conveyor to stand up, it pulls the patient's foot forward, preventing the patient's lower leg from exerting force to resist. This ensures that the intelligent nursing device can deflect the force of the patient's resistance. Attached Figure Description

[0043] 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.

[0044] Please see Figure 1 The present invention provides a technical solution: an intelligent nursing device for psychiatric care, including a seat 1, a backrest 2, armrests 3 and a limiting seat 4. The top of the seat 1 is provided with an anti-slip mat 101. The backrest 2 is fixed to one side of the seat 1. Armrests 3 are fixed to the two side edges of the seat 1 and the backrest 2. Connecting frames 16 are fixed to the two side edges of the top of the backrest 2. A flip frame 17 is rotatably sleeved on the upper side of the connecting frame 16. Cantilever arms 18 are fixed to both ends of the flip frame 17. A player speaker 19 is fixed to the side of the cantilever arm 18. A display screen 20 is rotatably connected to the end of the cantilever arm 18 away from the flip frame 17. A limiting pin is fixed to the outer side of the cantilever arm 18 near the connecting frame 16, perpendicular to the surface of the cantilever arm 18, and the limiting pin is used to limit the horizontal flip angle of the cantilever arm 18.

[0045] In practice, the psychiatric patient is guided to sit on the seat 1 of the nursing device. When the patient is not seated on the seat 1 and is restricted, the conveyor belt 12 will not operate, ensuring the safety of the patient. The flipping frame 17 rotates around the connecting frame 16, so that the cantilever 18 is laid flat and the display screen 20 is placed in front of the patient. The angle of the display screen 20 is adjusted to suit the patient's viewing needs. The display screen 20 and the speaker 19 are then used together, and with the guidance of the doctor, the patient's attention is diverted and the patient's resistance is alleviated, thus completing the daily care of the patient.

[0046] Please see Figures 1-9 A limiting seat 4 for restricting sitting posture is provided on the side of the seat 1 away from the backrest 2. A binding clamp 6 for restricting swaying is symmetrically provided on the upper side of the anti-slip mat 101. The binding clamp 6 is made of rubber and has a cushioning and protective effect when restricting the upper body. The upper edge of the limiting seat 4 has symmetrically opened notches. A pressure sensor 401 is embedded in the notch of the limiting seat 4. The inside of the limiting seat 4 has a storage cavity 402. A locking ring 403 is provided in the middle of the storage cavity 402. A rack 404 is fixed on the outer side of the locking ring 403. The locking ring 403 and the storage cavity 402 are slidably connected. The racks 404 on the outer side of the locking ring 403 are evenly distributed.

[0047] The center of the limiting seat 4 is provided with a drive mechanism 5 for adjusting the reciprocating rotation of the locking ring 403. The drive mechanism 5 includes a drive motor 501, a driving bevel gear 502, a driven bevel gear 503, a universal joint 504, a slanted turntable 505, a limiting sleeve 506, and a spiral strip 507. The drive motor 501 is installed at the bottom of the limiting seat 4. The output end of the drive motor 501 is fixed with the driving bevel gear 502. The driven bevel gear 503 is meshed with one side of the driving bevel gear 502. The surface of the limiting seat 4 is provided with an L-shaped opening for assembling the driving bevel gear 502 and the driven bevel gear 503. The two slanted turntables 505 are symmetrically distributed about the driven bevel gear 503, and the included angle between the two slanted turntables 505 is 50°. The two sides of the driven bevel gear 503 are connected to the slanted turntables 505 through the universal joints 504. The surface of the slanted turntables 505 is fixed with a spiral strip 507 that meshes with the rack 404.

[0048] The spiral 507 is meshed with the equally spaced racks 404 for transmission. When the spiral 507 rotates once with the slanted turntable 505, it can drive the locking ring 403 to move by an arc-shaped distance of an adjacent rack 404. Furthermore, the rotation direction of the slanted turntable 505 is perpendicular to the rotation direction of the locking ring 403, thereby ensuring that the locking ring 403 has a stable anti-pull effect after being discharged from the storage cavity 402.

[0049] Please see Figure 1 The limit seat 4 has slide rails 9 on both sides. The seat 1 is fixed with a T-shaped block near the inner wall of the limit seat 4. The slide rails 9 and the T-shaped block are slidably connected. The bottom of the limit seat 4 is symmetrically connected with a reserved cylinder 10 through a movable seat. The lower end of the reserved cylinder 10 is movably connected to the upper surface of the fixed frame 11.

[0050] In practice, when a routine examination is required for a psychiatric patient, the cylinder 10 is extended and pushed upwards to move the limiting seat 4. This causes the slide rails 9 on both sides of the limiting seat 4 to slide along the T-shaped block inside the seat 1. The two notches on the upper side of the limiting seat 4 then grip the patient's thigh from bottom to top. When the limiting seat 4 rises to the point where the pressure sensor 401 senses contact with the patient's leg, the pressure sensor 401 transmits a signal to the matching PLC controller, causing the PLC controller to stop the cylinder 10.

[0051] Then, the drive motor 501 of the drive mechanism 5 drives the active bevel gear 502 to rotate, so that the active bevel gear 502 drives the driven bevel gear 503 to mesh and transmit. At the same time, the two sides of the driven bevel gear 503 drive the two sets of slanted turntables 505 to rotate symmetrically and synchronously through the universal joints 504. When the slanted turntable 505 rotates forward, it meshes with the rack 404 on the outside of the locking ring 403 through the spiral strip 507 on its surface. Thus, the continuously rotating spiral strip 507 can push the locking ring 403 out along the opening of the receiving cavity 402, so that the locking ring 403 flips and unfolds at the recess of the limiting seat 4 and locks the thigh of the psychiatric patient, thereby restricting the patient's sitting posture and preventing the patient from standing up. This achieves automatic restriction of the patient's resistance movements by the legs, eliminating the need for medical staff to perform multiple leg restraints in a tedious manner, thus saving manpower and protecting the operation safety of medical staff.

[0052] Conversely, when the drive motor 501 is started and rotated in the reverse direction, it can drive the inclined turntable 505 and the spiral strip 507 to rotate in the opposite direction, so that the locking ring 403 can be retracted into the storage cavity 402, thereby releasing the restraint on the patient's legs.

[0053] Please see Figures 5-9 The surface of the limiting seat 4 is provided with a through hole for the inclined turntable 505 to reciprocate. The outer edge of the inclined turntable 505 is provided with an annular protrusion, and the annular protrusion is slidably connected to the limiting sleeve 506. The limiting sleeve 506 is installed in the through hole on the surface of the limiting seat 4. The receiving cavity 402 is connected to the through hole. By opening a through hole on the surface of the limiting seat 4 and connecting the receiving cavity 402 to the through hole, it can be ensured that when the inclined turntable 505 rotates, it drives the spiral strip 507 to mesh with the rack 404 on the outer side of the locking ring 403. When the inclined turntable 505 rotates, it will drive the annular protrusion on the outer edge to rotate along the limiting sleeve 506, ensuring that the inclined turntable 505 has a stabilizing effect against shaking when rotating at an inclined angle.

[0054] Please see Figures 3-9Both sets of inclined turntables 505 are provided with convex tooth blocks 508 distributed at equal angles on adjacent sides. The convex tooth blocks 508 are meshed with the transmission gear 509. A central shaft is fixed in the middle of the transmission gear 509. One end of the central shaft of the transmission gear 509 is movably connected to the bearing on the surface of the limit seat 4. The other end of the central shaft of the transmission gear 509 is fixed to the winding wheel 510. The surface of the winding wheel 510 is fixed to one end of the wire rope 602. The other end of the wire rope 602 is fixed to the moving plate 601. The length of the wire rope 602 is greater than the distance from the winding wheel 510 to the moving plate 601.

[0055] The surface of the anti-slip mat 101 has two sets of parallel guide grooves 102. The support feet at the bottom of the binding clamp 6 are inserted from the upper side of the guide grooves 102. The bottom of the support feet of the binding clamp 6 is also fixed with a movable plate 601. The surface of the seat 1 near the anti-slip mat 101 has a sliding groove 7 for the movable plate 601 to dock with. A return spring 603 is connected between the movable plate 601 and the sliding groove 7. The movable plate 601 forms an elastic sliding structure with the return spring 603 and the sliding groove 7. The binding clamp 6 slides along the guide grooves 102 on the surface of the anti-slip mat 101 through the support feet at the bottom, which can ensure that the binding clamp 6 has a stable anti-deviation function when moving. When the psychiatric patient sits on the seat 1 and leans against the backrest 2, the upper body of the psychiatric patient will be between the two binding clamps 6, thereby restricting the posture of the patient's upper body.

[0056] In practice, when the two sets of inclined turntables 505 rotate forward to drive the locking ring 403 to unfold, the forward-rotating inclined turntable 505 can mesh with the transmission gear 509 through the convex tooth block 508 on the side away from the spiral strip 507, so that the central shaft of the transmission gear 509 drives the winding wheel 510 to wind and wind the wire rope 602, setting the wire rope 602 to a sufficient length. When the locking ring 403 completes the restriction on the legs, the continuous winding of the wire rope 602 by the winding wheel 510 can drive the two sets of moving plates 601 to move closer to each other, and the moving plates 601 will also squeeze and contract the return spring 603, so that the two sets of moving plates 601 respectively drive the binding clamp 6 to clamp and restrain the upper body of the psychiatric patient, thereby strengthening the upper body to prevent swaying in the patient's resistance.

[0057] When the slanted turntable 505 reverses and drives the locking ring 403 to retract into the storage cavity 402, the transmission gear 509 will drive the winding wheel 510 to reverse and gradually loosen the wire rope 602. Under the reset action of the reset spring 603, the moving plate 601 can be driven to slide along the slide groove 7 to ensure that the two sets of binding plates 6 are far apart from each other, making it convenient for psychiatric patients to get up and move around.

[0058] Please see Figure 1 , Figure 2 and Figure 5The drive motor 501 is fitted with a bottom protective shell 8. A side protective shell 801 is provided on the side of the limiting seat 4 near the anti-slip pad 101, and a side protective shell 802 is provided on the side of the limiting seat 4 away from the anti-slip pad 101. Connecting ears are fixed on the lower side of both the side protective shell 801 and the side protective shell 802. The bottom protective shell 8 is fastened to the connecting ears of the side protective shell 801 and the side protective shell 802 by screws. The two sides of the bottom protective shell 8 are installed to the bottom of the limiting seat 4 by screws. The central shaft of the transmission gear 509 is connected to the reserved hole on the surface of the side protective shell 801 through a sleeve bearing to ensure that the central shaft of the transmission gear 509 can drive the winding wheel 510 to operate stably.

[0059] In specific implementation, by installing the bottom cover 8 on the lower side of the limiting seat 4, and installing the first side cover 801 and the second side cover 802 on both sides of the bottom cover 8, the bottom cover 8, the first side cover 801 and the second side cover 802 can isolate and protect the drive mechanism 5, ensuring that the drive mechanism 5 will not affect the safety of the psychiatric patient sitting on the seat 1 when it is running. When the bottom cover 8, the first side cover 801 and the second side cover 802 are removed, the components of the drive mechanism 5 can be lubricated and maintained.

[0060] Please see Figure 1 , Figure 10 and Figure 11 A fixing frame 11 is fixed to the lower side of the seat 1. A belt conveyor 12 is provided inside the fixing frame 11. A support plate is fixed between the fixing frames 11. Weighing sensors 15 are fixed on both sides of the support plate. A mounting seat 13 is connected to the top of the weighing sensor 15. A support roller 14 is connected between the two mounting seats 13.

[0061] In practice, the limiting seat 4 and the drive mechanism 5 work together to restrain the psychiatric patient on the seat 1 of the nursing device. When the patient resists and tries to stand up, the patient's feet will push down towards the ground. Since a belt conveyor 12 is installed on the lower side of the seat 1, when the patient's feet step on the belt conveyor 12, the weighing sensor 15 will sense the downward supporting force of the mounting seat 13 and the support roller 14. When the value sensed by the weighing sensor 15 is large, the belt conveyor 12 is controlled to rotate forward, driving the upper side of the transmission belt to rotate away from the seat 1. Thus, when the patient steps on the belt conveyor 12 to try to stand up, it will pull the patient's feet forward, preventing the patient's lower legs from exerting force to resist. The baffles protruding on both sides of the fixed frame 11 can block the sides of the patient's legs, preventing the patient's feet from stepping on the edge of the fixed frame 11. This ensures that the intelligent nursing device can deflect the force of the patient's resisting movements and can more efficiently assist doctors in providing rehabilitation care for psychiatric patients.

[0062] A method for using an intelligent nursing device for psychiatric care includes the following steps:

[0063] S1: The cylinder 10 pulls the limiting seat 4 down to its top, which is flush with the upper side of the anti-slip pad 101;

[0064] S2: By rotating the flip frame 17 around the connecting frame 16, the cantilever 18 is flattened and the display screen 20 is placed in front of the patient. The display screen 20 and the player speaker 19 are used to divert the patient's attention and alleviate the patient's resistance.

[0065] S3: When a psychiatric patient is sitting on seat 1 for a nursing examination, cylinder 10 pushes the limiting seat 4 upward and uses the notch of the limiting seat 4 to separate the patient's two legs.

[0066] S4: When the limit seat 4 rises to the point where the pressure sensor 401 senses contact with the patient's leg, the driving mechanism 5 is controlled to operate to drive the locking ring 403 to unfold and lock the patient's thigh, thereby restricting the patient's sitting posture and realizing automatic restriction of the patient's resistance movements by the legs.

[0067] S5: When the locking ring 403 flips and restricts the movement of the patient's legs, the winding wheel 510 winds and winds the steel wire rope 602, thereby simultaneously pulling the two sets of binding plates 6 to restrict the upper body of the patient, so as to reinforce the upper body against the patient's resistance.

[0068] S6: Use straps to restrain the patient's hands to the handrail 3, and use instruments to perform routine nursing checks on the patient's body.

[0069] In summary, medical staff can guide psychiatric patients to sit on the seat 1 of this nursing device, and use the display screen 20 and speaker 19 in conjunction with the doctor's guidance to divert the patient's attention and alleviate the patient's resistance. At the same time, when using the nursing device to divert the psychiatric patient's attention, the driving mechanism 5 drives the locking ring 403 of the limiting seat 4 to restrain the patient's thighs. Simultaneously, the linkage structure drives two sets of tight-fitting clamps 6 to restrict the patient's upper body posture. This ensures that the intelligent nursing device assists doctors in performing routine physical examinations, emotional relief, medication persuasion, and drug treatment for psychiatric patients.
