Description

[0001] Mobile device for dialysis

[0002] The proposed utility model relates to medical equipment, especially to water purification systems for hemodialysis. The utility model is related to the medical field and mainly relates to mobile medical equipment. The device is largely related to the technical aspects of medical devices, especially mobile dialysis devices.

[0003] The mobile medical and diagnostic complex is made in the form of functional modules: laboratory and diagnostic, clinical and diagnostic, X-ray and diagnostic, surgical and sterilization, intensive care, hyperbaric oxygenation, detoxification, pharmacy modules, as well as two-axle vehicles and trailers equipped with medical devices. This complex provides for the reception and treatment of at least 100 patients with injuries and surgical diseases per day. For remote reception and transmission of medical data during the rescue of victims, technical means are USED, such as subscriber and base broadband radio stations, which interact with local computing radio stations and wireless computer networks of medical battalions through trunk channels. The device also includes various sensors and a housing [1].

[0004] The disadvantage of the mobile diagnostic and treatment complex is its inability to fully provide dialysis treatment. This device is more suitable for diagnostics and does not play a significant role in the treatment of the patient [1].

[0005] Another analogue is a portable mobile device for dialysis. The portable mobile device consists of a dialysis machine body on which the control panel is located; in the lower part of the body there is a base in the center of which there is a first hole; the lower part of this hole is connected to a telescopic device; an auxiliary moving device is rigidly connected to the lower part of the telescopic device. The telescopic device is used to ensure contact of the auxiliary device with the ground, which allows for the complete movement of the dialysis machine body: the infusion replacement arm is connected to the other side of the dialysis machine body through a fixing seat; in the infusion replacement arm there is a height adjustment device, which is rigidly connected to the clamp part, clamps the dialyzer and is used to adjust its height.The portable mobile device allows you to adjust the overall height of the dialysis machine body and easily move or fix it if necessary [2].

[0006] The disadvantage of a portable mobile dialysis device is the presence of an additional water tank, which makes it difficult to transport the system [2].

[0007] A mobile peritoneal dialysis device was chosen as another analogue. It includes a mobile support consisting of separately located upper and lower supports. The lower support has wheels at the bottom, and the upper part has a weight sensor and a lifting mechanism for lifting the upper support. After lifting, the upper support is in a high position, remote from the weight sensor, and under the action of gravity it falls to a low position. The upper support consists of upper and lower layers, the upper layer has a place for installing a dialysate bag, and the lower layer has a place for a waste bag [3]. A disadvantage of the mobile peritoneal dialysis device is the presence of an additional water tank, which complicates the transportation of the system [3].

[0008] The prototype chosen is a device called "Methods and systems for preparing peritoneal dialysis solution and / or therapeutic devices". The described device is also adapted for the preparation of drugs directly at the site of their use. In particular, mixing systems using replaceable long-acting concentrates are described. The main advantages include sterilization and precise mixing of water and concentrate for immediate use, as well as other advantages [4].

[0009] The dialysis therapy device consists of a housing, a pump, a filter, sensors and a membrane and includes: ● A fluid circuit integrated with a mixing container, which is pre-connected to the fluid circuit and isolated from the environment;

[0010] ● The liquid circuit includes valve actuators and connections that form a valve network that determines the direction of flow in the system; ● The valve network includes a pump element and a liquid inlet pipe with a connector for connection to a liquid source, which is connected to a mixing container via a pump;

[0011] ● The valve network connects the mixing container to the liquid inlet;

[0012] ● The inlet pipeline is provided with at least one sterilization filter, including an air testing filter and / or a pair of split sterilization filters [4].

[0013] The disadvantage of the device is the presence of an additional water pump, which makes it difficult to transport the system. In addition, the device does not have an integrated ultraviolet irradiator, which can lead to incomplete diagnostic results in humans [4].

[0014] The objective of the utility model is to improve the comfort of the dialysis process for patients. The main goal is to create a mobile dialysis device that is compact and portable, without requiring a water tank or water pump.

[0015] The essence of the utility model is that the mobile device for dialysis, consisting of a housing, a pipeline for water supply installed in the housing, a filter for large particles, a carbon filter for repeated purification, a pressure gauge, sensors, a pump, an osmotic membrane with a first outlet for purified water and a second outlet for removing contaminated water, sequentially connected to the first membrane outlet by an anti-valve, a rotameter and an ultraviolet lamp, includes a pressure sensor connected to the ultraviolet lamp outlet through a pump and an electromagnetic valve. The outer end of the water supply pipeline is designed with the possibility of connection to an existing water source. The housing is made in the form of a sealed container installed on hinged support elements, which ensures its movement and installation in the open air in emergency situations.

[0016] The solution to the problem is achieved by the fact that a pressure sensor is additionally installed at the system outlet, which plays an important role in regulating the water pressure. Water enters the osmosis inlet, particles insoluble in water are purified through a 5-micron filter and enter the carbon filter. Organic particles purified in the carbon filter enter the pressure gauge (used to control the water pressure) and then the electromagnetic valve.

[0018] Fig. 2 - Electrical diagram of the osmosis system

[0019] Water enters the osmosis inlet, is purified through a 5 micron filter (1) and a carbon filter (2). In the carbon filter (2), organic substances are removed, after which the water enters the pressure gauge (used to control the water pressure) (3) and then into the electromagnetic valve (4). The electromagnetic valve (4) regulates the water flow based on signals from the pressure sensors (5, 16).

[0020] The pressure sensor (5) monitors the inlet pressure and protects the system from running dry when there is no inlet water. Pressurized water is supplied to the osmosis membrane (8) by the water pump (6), and the membrane inlet pressure is monitored by the pressure gauge (7). Clean water is measured by the water coding device (12), then passes through the rotameter (13) and ultraviolet irradiation (14), after which it enters the anti-valve (15) and then the pressure sensor (16). The second membrane outlet passes through the manually controlled valve (9) and the rotameter (11), then it is discharged into the sewer. At the second outlet of the device, the electromagnetic valve (10) is connected in parallel, used to flush the membrane when the device is first started. Since the inlet water pressure in dialysis devices reaches 3 atmospheres, the outlet pressure sensor (16) is regulated within 2.5-3 atmospheres.

[0021] When initially connected to the network, the signal passes through the water coding measuring device (I), the inlet (2) and outlet (3) pressure sensors, the valve (8), the pump time relay (5) and the bypass time relay (6). The pump time relay switches on the pump (9) 3-4 seconds after the relay (4) is activated. The bypass time relay opens the bypass valve for 10 seconds to flush the membrane. After this, the bypass valve closes and the system operates normally. The clean water outlet pressure is regulated by the outlet pressure sensor.
