Description

 The invention relates to medicine, in particular to surface modification devices for medical devices, including natural latex, for example, medical gloves or condoms.

 Known devices for surface treatment of medical gloves made of natural latex using polymer coatings containing antiseptic substances (1).

 The compositions proposed in this case cannot fully ensure the prevention of possible infectious complications in case of violation of the integrity of the glove during medical procedures and do not provide a beneficial effect on the skin.

 Closest to the proposed solution is a protective coating of medical gloves with an antibacterial agent and an additional substance that reduces sweat, deposited on the inner surface of the gloves (2).

 The disadvantage of this solution is that the compositions for surgical antiseptic coatings of gloves do not have antiviral and hypoallergenic effects, and while suppressing sweating, they negatively affect the physiological functions of the skin of the surgeon's hands.

 The aim of the present invention is to remedy these disadvantages and to provide a device for coating the inner surface of medical products made of natural latex, for example, surgical gloves or condoms, which has antiseptic and neutralizing properties in relation to the effusion of the surgeon's hands and has a beneficial effect on the skin or mucous membranes.

 This goal is achieved by the fact that in the device containing the chamber and the holder with the workpiece, a dosing unit is introduced as part of the container, a measuring unit with a regulator and a mixer connected through a valve to the air duct, the mixer outlet is connected to the first and second channels with nozzles located in the chamber directed through the first and second reflectors, along the edge of which the first and second electrostatic rings are fixed, respectively, to the electrostatic holder with the product located between them, as well as the unit control unit as part of the inclusion unit, the rotation unit of the measuring unit of the dosing unit, the start unit, the time relay, the actuator key and the electrostatic generator, the first output of which is connected to the holder electrostatic, and the second output is connected to the first and second electrostatic rings, the input of the electrostatic generator is connected to the input the duct valve and through an actuator key is connected to a time relay, the first input of which is connected to the first input of the start-up unit by the input of the turn unit and the output of the turn-on unit, and the second input is connected to the output of the launch unit, the second input of which is connected to the output of the rotation unit, which in turn is mechanically connected to the measuring unit with the controller of the dosing unit.

 The device (see drawing) consists of a dosing unit 1 comprising a container 2, a measuring unit 3 with a regulator, a mixer 4, an air duct 5 with a valve 6, and also a chamber 7, with the first 8 and second 9 channels with nozzles placed therein, the first 10 and second 11 reflectors, first 12 and second 13 electrostatic rings and an electrostatic holder 14 with the product.

 The control unit 15 of the device includes a switching unit 16, a turning unit 17 of the measuring unit 3, a starting unit 18, a time relay 19, an actuator key 20 and an electrostatic generator 21.

 The device operates as follows. The substance intended for application to the surface of the product, for example, surgical gloves or condoms, is loaded into the container 2. The processed product is put on the holder 14 electrostatic and placed in the chamber 7. Using the switching unit 16, the device is started. In this case, the turning unit 17 and the measuring unit 3 with the regulator of the metering unit 1 are turned on, rotating along its axis with the help of an adjustable measuring capacity on its surface, it takes a certain predetermined quantity of substance from the container 2 and loads it into the mixer receiver 4. The enable signal resets the relay 19 time and sets it to its original state. When the half-turn and the shipment of the substance with the rotation nodes 17 is completed, the enable signal is received at the second input of the start node 18, and the reference signal of the coating period starts at the second input of the time relay 19. The time relay 19 can be performed according to any scheme of a controlled timer with a set period of operation, the design of which does not matter.

 The time relay 19 for a given period of operation includes an actuator key 20, from the output of which a signal for turning on the pneumatic valve 6 and the electrostatic generator 21 is supplied.

 By turning on the pneumatic valve 6, compressed air is opened through the duct 5 into the mixer 4. From the mixer 4, the mixture for antiseptic coating enters the spraying chamber 7 through the first 8 and second 9 channels with nozzles. The nozzles of the channels are directed, respectively, to the first 10 and second 11 reflectors of the mixture, with the help of which dispersed spraying occurs. During the spraying period, respectively, the first 12 and second 13 electrostatic rings are placed on the edge of the reflectors. At this time, the holder 14 electrostatic with the workpiece is charged with the opposite charge. As a result, the charged mixture directed by the air flow to the object being processed uniformly and sufficiently tightly adheres to the surface of the glove or condom attached to the holder 14 by electrostatic charge charged opposite to the mixture. In this case, the microparticles of the substance intended for surface treatment of the product penetrate into the pores and microcracks of the product and further increase its protective properties.

 After the process of applying the protective mixture to the surface of the product is completed, the time relay 19 turns off the actuator key 20 and the control unit 15 of the device for spraying the substance goes into standby mode.

 The residual substance settles in the chamber 7. The product is removed from the holder by inversion, and the surface with the applied substance becomes internal. The subsequent operation includes packaging the product and, if necessary, sterilization.

 Dosing of the coating agent is carried out using the regulator of the 3-dimensional unit, the dosing unit 1, which determines its maximum quantity for placement in the mixer 4. By changing the static voltage at the output of the high-voltage generator, the quantity of the mixture is fixed, which is fixed on the surface of the workpiece. The antiseptic mixture is fixed due to the fact that its particles flying through the electrostatic rings, which are a structure of electrically conductive material charged using an electrostatic generator, transfer their charge to this mixture. The latex product is worn on an electrostatic holder, also made of an electrically conductive material, but charged with the opposite charge with respect to the mixture. In this case, the electrostatic charge flows onto the surface of the workpiece and captures the antiseptic mixture.

 This solution allows to obtain a highly effective antimicrobial and antiviral protective coating, which also has a beneficial effect on the skin of the surgeon’s hands when treating the surface of surgical gloves and when treating the surface of condoms and has a rather effective antimicrobial and antiviral effect in the treatment of a number of diseases.
