SU376095A1 - DISINFECTING FLUID SPRAYER - Google Patents

Description

one

The invention relates to medical technology.

Disinfectant dispensers are known, including a reservoir for liquids, a hollow stem piston pump, a shut-off valve and a spray tip. Their spraying is pulsating and, in addition, they are hard to control in their work, since the pump requires a lot of muscular tension.

The proposed nebulizer differs from those known in that a closed reservoir-receiver is installed on the upper part of the hollow stem, which communicates with the stem cavity through the holes formed in the wall of the stem. This embodiment of the sprayer provides continuous spraying and easy operation of the fluid, which facilitates the work of the disinfector.

FIG. 1 shows the proposed sprayer in general form with a partial section; in fig. 2 - the lower part of the rod in the section; in fig. 3 - the upper part of the rod with the reservoir-receiver.

A reservoir 1 for the working fluid with a filling hole, closed by a plug 2, and a piston pump 3 are placed in the case 4 with a lash 5. Tripod 6 is connected to the pump 3 by a pressure hose 7. The tip 8 of the distributor is attached to the tripod. A clamp 9 is provided to stop the flow of fluid from the pump to the spray tip.

The piston pump consists of a cylinder 10, a piston // and a hollow rod 12. A cap nut 13 and a cover 14 are fixed on the cylinder 10 and the cap 14 by means of which the pump 3 introduced into the tank 1 is set to the operating position. Drain holes 15 are located in the upper part of the cylinder, and a suction valve with filter 6 is installed in its lower part. A nut 17 with recesses is screwed onto the end of the rod 12.

to secure the protrusions 18 of the cuff 19 therein. The cuff is made of an elastic, corrosion-resistant, non-hygroscopic material, such as polyethylene. It has the shape of a truncated cone. Inside

a stop is placed for the stop valve 20 placed in it. The stop valve is provided with an internal thread and, like the piston 11, is screwed onto the end of the rod 12. At the upper part of the stem is mounted a reservoir receiver 21. At the level of its bottom, on that part of the rod that passes the reservoir of the receiver, there are two coaxially arranged opposite each other 22. The cavity 23 in the brush, located above the holes 22, is not

It has an exit to the outside and forms an air chamber that is additional to the tank-receiver A hole is made at the bottom of the receiver tank with a clamp 24 for connecting the pressure hose 7 connecting the

pump 3 with a spray tip 8.

The spray tip contains a cap 25 and a two-way divider. The front wall of the handpiece at the inlet has a thickness equal to approximately one third of the diameter of the outlet.

The tripod 6 is made in the movable telescopic elements 26, 27, inside which the hose 7 passes, connected at one end to the receiver 24 of the reservoir tank, and the other to the spray tip 8 mounted at the top of the element 27.

The sprayer is used as follows.

Before starting work in tank 1, a piston pump 5 is installed. The tank, placed in a case, is filled with a working fluid, the filling opening is closed with a stopper and a light is supplied through the shoulder. The stand 6 is extended to the required height and fixed in this position with the screw 28. The rod 2 is raised and the liquid from the reservoir / fills the cylinder Yu of the pump. After that, the rod is lowered, slightly pressing on it, while the lower part of the cuff 19 automatically expands, provides reprvity and at the same time takes the position where the contact surface of the cuff with the walls of the cylinder 10 is minimized. Due to this, ease of movement of the piston is achieved at a low cost of muscular energy disinfector.

When onuskanni shtoka fluid under pressure opens the locking clan, 20 and passes into the cavity of the rod, lifting up to the holes

22, through which it enters the reservoir of the receiver 21, and from there, under pressure, to the spray tip 8, by means of which it is applied to the surface to be treated. Zioln reservoir-reservoir, the liquid squeezes the air in the tank, and in the cavity of the rod. Its volume becomes minimal and its pressure maximal (from 6 to 9.5 atm). When the fluid flows to the spray tip and into the stem cavity below the orifices 22, the volume of air increases, however, it becomes harmful to the fluid that fills the stem cavity below the orifices 22, and therefore the air pressure on the fluid remains sufficient for the spray process to reach the allowable value of the channel.

Since when lowering the Nern // part of the liquid can leak into the piston

the space then for removing it back into the tank / are the holes 15, replacing the seal in the union nut.

Subject invention

A disinfectant sprayer comprising a reservoir for the liquid, a piston pump with a hollow stem, a shut-off valve and a spray tip, characterized in

that, in order to ensure uninterrupted separation and to facilitate the work of working with them, a closed reservoir-receiver is installed on the BOTTOM FLETTER, which communicates with the cavity of the rod through the holes formed

in the wall of the rod.
