Description

[Detailed explanation of the invention] This invention consists of a cylindrical vessel from the upper end to the lower end.
A filtration body is inserted into which a concentrated sterilizing solution is permeated, and hollow fibers of synthetic fibers with a sterilizing agent attached to the outside are arranged vertically and assembled together. A sterile water sampler, which is made by infiltrating a concentrated sterilizing solution and inserting a synthetic fiber cotton-like filter with a sterilizing agent on the outside, is connected in this order to a heater, a pressure pump, and a solenoid valve. This invention relates to a sterile water sampling device for an operating room connected to the end of a water pipe.

When performing a surgery at a hospital or clinic, doctors and nurses usually thoroughly disinfect the area beyond the elbow joint with disinfectant, rinse it with sterile water, and then put on surgical gloves. The known sterile water collection devices include reverse osmosis sterile water collection devices or distilled water cooled sterile water collection devices.

In these devices, there is a gap between the faucet that discharges sterile water, the heater, and the pressure pump, so there is a risk that bacteria that has entered from the faucet may enter the water pipe and flow back. cannot be done easily due to high equipment costs.

On the other hand, devices with relatively low equipment costs include ultraviolet irradiation sterile water sampling devices and ozone-free sterile water sampling devices.

However, these devices have the disadvantage that they do not completely eliminate bacteria, and bacteria can enter the water pipe through the faucet and flow back.

Since each device has its advantages and disadvantages, the current situation is to carefully collect sterile water by adding other possible means.

This design reduces the distance between the faucet, the heater, and the pressure pump, and collects sterile water from the mouth where the sterile water sampler and the dew-shaped drain are connected and integrated. Because it is a water pipe, there is no room for bacteria to enter the water pipe and flow back.
However, the proposed method is extremely cheap and can be easily replaced.
Since it is disposable and must be replaced every 3 to 4 months, it is possible to collect completely sterile water, and the equipment is simple and economical.

To explain this with an example, a cylindrical container 1 of an appropriate size made of synthetic resin is infiltrated with a concentrated sterilizing solution from the upper end to the lower end, and then a fine powder is applied to the outside. A filter body 3, which is made by vertically arranging hollow fibers 2 of synthetic fibers sufficiently impregnated with a disinfectant, is inserted without any gaps, and is also inserted into a raindrop-shaped drain port 4 connected to the cylindrical vessel body 1. A sterile water sampler 6 is formed by infiltrating the inside with a sterilizing solution at a concentration of is connected to a water pipe 10 in the order of a heater 7, a pressurizing pump 8, and a solenoid valve 9 close to the upper part at short intervals, and is removably connected to the lower end of the same wood pipe 10 by a screw 11 for use in an operating room. It is a sterile water sampling device, and in the figure, 12 is a mounting plate, 13 is a mounting rod, 14 is a class, 15 is a front leg, 16 is a washbasin, 17 is a sewer pipe, 18 is a switch, 19 is a screw part, and 20 is a wall. ,2
1 is a floor, and 22 is a drainage hole.

This proposal has a structure similar to an upward slope, and the water pipe 1
0 is connected to a water source, a heater 7 heats water supplied from a water pipe 10, and a pressurizing pump 8 discharges an appropriate amount of heated water according to a command from a solenoid valve 9.

Heated water flows into the sterile water sampler 6 from the lower end of a water pipe 10 connected to the electromagnetic valve 9.

The solenoid valve 9 can be opened and closed freely by pressing the switch 18 mounted on the floor 21 with the tip of your shoe, so when collecting sterile water, hold both hands between the washbasin 16 and the drain hole 4. If you lightly press the switch 18 on the floor 21 with the tip of your shoe, the solenoid valve 9 will operate and issue a command to the pressure pump 8 and heater 7, and depending on how firmly you press the switch 18, the appropriate amount of heated water will be released. drains water.

The drained heated water enters the cylindrical vessel body 1 from the category 14, infiltrates the filter body 3 inside the vessel body, passes through the front legs 15, enters the drizzle-shaped discharge port 4, and enters the cotton-like filter body inside the discharge port. 5 and passes through the drain hole 22 as sterile water, which is discharged to the outside.

During this time, the heated water is further inserted into the drizzle-shaped drain port 4 using a concentrated sterilizing solution that has permeated the synthetic fiber hollow fibers 2 inserted into the cylindrical vessel body 1 and a finely powdered sterilizing agent attached to the outside. It can be used with confidence because it is completely sterilized by the concentrated sterilizing liquid that has penetrated into the cotton-like filter body 5 made of synthetic fibers and the finely powdered sterilizing agent attached to the outside before being discharged.

Even if the water droplets after use remain in the drain hole 22 of the drain hole 22 of the drain hole 4 and the bacteria attached to the water droplets enter the drain hole 4, the bactericidal liquid and disinfectant in the cotton-like filter body 5 will It can be killed.

Therefore, even if the drainage is stopped, there is no concern that bacteria will live in the filter body 3 within the cylindrical vessel body 1.

The length of the cylindrical body 1 in this case is usually about 30 cm, and it is used every day and replaced with a new one every 3 to 4 months. It's not a burden.

As described above, the present invention has a simple structure and economical equipment, and can collect sterile water that completely kills pyrogen, a pyrogen, and other bacteria.
