Description

A device for loading a disabled person into a tank with liquid (options).

The utility model relates to medical equipment for the rehabilitation of persons with disabilities with a violation of the musculoskeletal system.

A device for mounting a shooting chamber is known that comprises lifting and turning boom mechanisms with drives from low power engines, the lifting mechanism being made in the form of a articulated lever mechanism, on the input link of which there is a platform that maintains a horizontal orientation in any position, and a balancing mechanism.

The disadvantage of this device is the bulkiness of the rotation and balancing mechanisms, as well as the insufficient lateral stability of the articulated link mechanism (UK application No. 2163720).

A device is also known for immersing a disabled person in a liquid tank containing mechanisms for turning the seat and raising it (PCT application No. 86/02544).

The disadvantages of the device include its narrow functionality, since it cannot be used for people with disabilities with significant disorders of the musculoskeletal system. So, for example, it is problematic to move a disabled person from a gurney to the seat of this device. For the operation of the device, a source of compressed air is required, which also narrows the possibilities of its use.

A device for lifting patients is also known, comprising a rack with a rotation mechanism, an arrow mounted on it, at the end of which a transport device with a seat is fixed. Lift drive

boom is at the same time a balancing element. The actuators used are linear actuators, (see US Patent No. 4,554,691)

The disadvantages of the device include low functionality, because for immersing a disabled person you should have significant movement of the seat, in particular, vertically and increased lateral stability, which requires increased structural rigidity. The low location of the drive motors does not provide electrical safety in a humid environment.

The closest in technical essence to the first embodiment of the utility model is a device for immersing a disabled person in a liquid tank containing a rack, mechanisms for turning and lifting the seat, and the lifting mechanism is made with a hydraulic actuator (see patent DE 19532595 publ. 08.08.1996).

The objective of the claimed utility model according to the first embodiment is aimed at improving the safety of the structure, expanding the functionality for use of the device by people with disabilities with significant disorders of the musculoskeletal system by increasing stability while maintaining the simplicity and reliability of the structure.

The closest in technical essence to the second variant of the utility model is also a device for immersing a disabled person in a liquid tank containing a rack, turning and lifting mechanisms for the seat, and the lifting mechanism is made with a hydraulic actuator (see patent DE 19532595 publ. 08.08.1996).

The objective of the claimed utility model in the second embodiment is aimed at improving the safety of the structure, expanding the functionality for the use of the device by people with disabilities with significant disorders of the musculoskeletal system by increasing stability

while maintaining the simplicity and reliability of the design. The device provides the movement of the disabled person to the tank, in particular to the pool due to the presence of the guide.

To solve this problem, in the device for immersing a disabled person in a liquid tank according to the first embodiment, comprising the mechanisms for turning and raising the seat, the lifting mechanism is made with a hydraulic actuator, the hydraulic actuator includes a rack in the form of a single-stage hydraulic cylinder with a rod and connected via a spool to the water supply, and the seat connected to the rod of the hydraulic cylinder.

The housing of the hydraulic cylinder can be fixed on the base.

To solve this problem, a device for immersing a disabled person in a liquid tank according to the second embodiment, comprising mechanisms for turning and raising the seat, the lifting mechanism is made with a hydraulic actuator, provided with a guide consisting of a section made by a helical line and a straight section, and the hydraulic actuator includes a stand in the form of a single-stage hydraulic cylinder with a rod and connected through a spool to a water supply, the guide is mounted on the hydraulic cylinder body, the seat is made with a roller mechanism, interacting yuschim with the guide, and is connected with the cylinder rod and the seat taken to be movable along the guide.

In FIG. 1 shows a general view of a device for immersing a disabled person in a tank (bath).

Figure 2 presents a General view of the device for immersing a disabled person in a tank (pool).

A device for immersing a disabled person in a liquid tank contains mechanisms for turning and raising the seat. The lifting mechanism is made with a hydraulic actuator. The hydraulic actuator includes a rack in the form of a single-stage hydraulic cylinder 1 with a rod 2 and is connected through a spool 3 (figure 1) with a water supply. The seat 4 is connected with the rod 2 of the hydraulic cylinder 1. In the second embodiment (Fig. 2), the seat 4 is made with a roller mechanism 5 interacting with the guide 6, and is connected with the rod 2 of the hydraulic cylinder 1, the seat 4 is arranged to move along the guide 6.

An example of the device.

As a reservoir with liquid used pool.

In the foundation near the pool (see Fig. 2) a socket is mounted in which a rack with a mechanism for raising the seat 4 is installed. The rod 2 of the hydraulic cylinder 1 is fixed to the back of the seat 4. The seat 4 has armrests and a removable footrest. The rotation mechanism is mounted on the rod 2 of the hydraulic cylinder 1 and includes a drive gear located in the tubular casing.

The device operates as follows.

In the initial position, the seat 4 is turned away along the side of the pool. The disabled person is delivered to the pool, for example, on a gurney. The operator, using the controls, raises the seat to the level of the gurney. Disabled person moves from wheelchair to seat 4. Disabled person's forearms rest on armrests.

When moving a disabled person from a wheelchair (from a wheelchair) to a seat with the right hand, the disabled person covers the handle of the control mechanism. Having displaced the handle, the invalid includes a cycle in the pool for moving the seat into the water. This cycle (as well as the reverse cycle from the pool) is performed automatically. Further, a disabled person can swim in the pool with his hands. After the rehabilitation procedure of swimming (bathing, massage), the disabled person swims up to the seat and sits in it in a partially underwater position. It moves the shaft of the handle and starts the cycle program for lifting, the reverse of the above.

MW

And so, the claimed utility model allows to obtain the following technical result: to increase the safety of the structure, to expand the functionality of the device, i.e. to ensure the possibility of its use in the pool for the disabled, as well as for the self-care of disabled people with disorders of the musculoskeletal system of medium and high severity; ensure the convenience of mixing the person on the seat with 4 devices from any wheeled vehicle for the disabled: strollers, wheelchairs, etc., simplify the management of the device by making it accessible to disabled people and increasing its reliability and safety in the event of water getting into the control mechanism, because The control mechanism is powered by water.
