Description

[Detailed description of the invention] "Tan" , issue 1 and January 1 The present invention relates to a purification device, and the detailed box further includes a purification device that cleans the hands and arms of a surgeon during surgery. It relates to washing and cleaning equipment.

In an emergency situation, saving a patient's life must be done before the surgical team enters the operating room. The length of time it takes to scrub often determines whether the patient survives or not. It is well known that it often depends on A typical pre-surgical cleaning will include Depending on the length of the surgery and the length of the surgery, it takes between 5 and 15 minutes. .

In the past, preoperative cleaning of surgeons and operating personnel followed a similar pattern. I was trampled on. Wash your hands to remove bacteria that could potentially infect the patient. Cleaning brushes and various chemicals are used. The cleaning must be thorough and careful. It is time consuming and in many cases irritating to the skin. That will happen. Furthermore, not all surgical personnel clean in the same manner. The results of washing vary from person to person, and even from wash to wash even for the same person.

Careful washing will remove bacteria on the skin surface, but the pressure between the follicles and the skin will increase. It has been found that it is less effective against bacteria present in the scars. This removal It is clear that bacteria that do not exist in the body act as a source of infection for the patient during surgery. It is.

Some of the issues associated with pre-surgical cleaning include the length of time it takes and the lack of Some bacteria are difficult to remove under and around fingernails. Damage to the bottle due to repeated washing for a long time, damage to some disinfectants. This includes each individual's sensitivity to detergents and detergents.

To overcome various shortcomings of prior art preoperative cleaning methods, U.S. Patent No. 3,757 , No. 806 discloses that a pressurized washing stream is used for the purpose of quickly washing both hands of surgical personnel. A pulsating hydro-jet cleaning device that utilizes body pulsating jets has been proposed. .

According to this, the hands and arms of each individual who washes and commands are arranged in the longitudinal direction of the gland. into the cleaning chamber containing the curved manifold, and place both arms and hands on the manifold. exposed to a pulsating jet of cleaning fluid that is discharged from the device. Therefore, the manifold In order to evenly expose the bowl to the pulsating jet of cleaning fluid that exits from the mouth, Rotate slowly.

When the latter manifold is operated at a pulse frequency of approximately 1500 pulses per minute, the The mist jet is particularly effective at removing dust and bacteria within the follicles and skin folds. It has been found that an effective compressive-non-compressive effect can be produced on human skin. this device The test results were 3, 5kg/cf (50psi) and 5.6kg/d. (80 psi) was maintained for 90 seconds. Cleanliness was found to be better than a conventional scrubbing action of 5 minutes. did.

These devices are extremely effective in clearing the skin in a short period of time. However, due to other reasons, it was proven that the application was insufficient for use, so the project was discontinued. I was left alone.

One of the drawbacks of prior art cleaning devices was that they produced a significant high pitched noise. . The unit vibrates significantly and is noisy during operation, making the unit noisy and It must be located in a particularly well-separated area to avoid disturbing people and other people. I didn't get nine.

This is because the room where the cleaning equipment is installed must be protected from noise to some extent. This means that it cannot be used in close proximity to the operating room.

One reason for this noise is when high-pressure fluids have to make sudden changes in direction. The reason lies in the use of tubes with bent corners. Furthermore, for other reasons , there is a pulsation of the cleaning fluid. In other words, this pulsation is 1 per minute from a state of zero pressure. The pressure changes from 0 to the maximum pressure about 500 times. Since the fluid was pulsating, the fluid It hits the pipe at the right angle joint, creating a considerable amount of blow and vibration.

Also, to actually clean the underside of your fingernails and the area around your fingernails, bend your fingers and use various The only option was to move the hand back and forth under the spray nozzle. Others, skin An effective means of cleaning, pulsating jets deliver pulses of high pressure to the skin. It has a "striking" effect and causes pain after repeated use. It has been proven that it is irritating to the skin.

Also, when using the unit, one person must hold both hands and arms of the cleaning device. Another person turns the operation switch to ``10,000'' and after a predetermined period of time, Two people were required to turn the operating switch "off" at the same time. Furthermore, both hands The opening into which both arms are inserted is designed to prevent the user's arms from being exposed to external sources of infection when the arms are withdrawn. There were no seals in place to prevent bacteria from entering.

Therefore, liquids splashed onto individuals using cleaning equipment, towels, or other equipment can be It stuck around the arm, creating a poor seal and a source of bacterial transfer. .

summary From this point of view, the present invention provides a movable tank for collecting cleaning liquid, which is pre-loaded under varying pressure. a pump device connected to the tank that circulates the liquid; and a pump device connected to the circulation pump. and spraying the liquid under the varying pressure onto the object to be cleaned. The present invention relates to a portable cleaning device that includes a nozzle device spaced apart so that the cleaning device can be used.

The novel invention also provides a cleaning fluid and circulates this fluid under pressure. , the fluid pressure is periodically changed from a maximum pressure to a minimum pressure, and the fluid pressure is changed periodically. The eye comprises a step layer which directs said fluid under pressure conditions towards the object to be cleaned. These and other objects of the invention also relate to methods of cleaning objects. , will become clear by referring to the following description and drawings.

Suitable materials for earth walls, side walls, back walls, front walls and bottom walls have a thickness of 12.7 f++m (1/ 2 inch) clean flexiglass, but any metal, as long as it is corrosion resistant, Other materials can also be used.

FIG. 10 shows a housing and a pressurized fluid receiving the pressure from a maximum to a minimum circumferentially. housing to provide partial fluid flow to the fluid distribution manifold that changes over time. It is a front view of the valve attached to.

One of the problems associated with the prior art is that pulsating jets of cleaning fluid are utilized. It is true. The cleaning fluid supply is fully on and fully off at high frequency. , the sudden stopping and surging of the fluid is unacceptable. This produces a significant percussion effect that generates a high noise level.

Therefore, the fluid pressure can be changed from maximum to minimum without completely interrupting the flow of cleaning fluid. It is necessary to change it periodically.

Therefore, in FIG. 10, the two-speed motor (102) is 2) Drive the belt pulley (104).

■The belt (108) is attached to a large pulley (110) installed on the shaft (112). ), connect ■belt pulley (104). The axis (112) has two outputs Valve housing with ports (116) and (118) and input port (120) (114) is rushing inside.

The cleaning fluid is supplied under pressure from a source such as a pump (not shown) to the input port ( 120). On the shaft (112) inside the valve housing (114) are two impellers (122) and (124) are provided.

As understood in connection with FIG. 12, impellers (122) and (124) are shaped like The shapes are generally figure 8 shaped and are spaced 90' apart. impeller The width of the flange forming the upper part and lower part by the figure 8 design of It is shorter than the diameter of force ports (116) and (118).

Therefore, as understood from Fig. 10, the flange ( 126) closes the million lift (118) to its maximum state and closes the orifice (11). g) only a small portion of the fluid distribution manifold connected to that orifice It can be freely flowed to the LD (20).

However, the impeller (124) rotatably extends 90'' from the impeller (124). 122) has its upper flange (123) and lower flange (130) connected to the orifice. From the orifice (116), the maximum water pressure is to a fluid distribution manifold (20).

However, with a 90° lag, the impeller (124) orients its flange. The impeller (122) is mounted on its upper flange (118) while the impeller (122) 28) or the lower flange (130) with the orifice (116) at its maximum Obstructed against pressure.

Therefore, the orifice (116) is connected to the manifold (20) for fluid distribution. The fluid at is at its maximum pressure state. This unique groove structure allows fluids to move can be distributed to each cleaning unit in each housing in a phase-shifted state, Thus, -M quiet operation of the device is possible.

As previously explained, fluids reduce noise levels and are associated with skin irritation. pulsating, not completely stopped or pulsating to allow continuous use. It is important not to be hit. This is for each impeller (122) and (124) This is achieved by the shape of the upper and lower flanges forming a

Form impellers (122) and (124) as shown in Figure 10. Each end of the flange is beveled. In Figure 11, the impeller (122) Assume that the upper flange (128) begins to move into the orifice (116). do.

At point A, the flange is just outside the orifice and the maximum pressure is at the orifice. passing through the system (116).

At point B, the flange (128) has the tip of the flange just in the orifice. (116) and is gradually moving to begin cutting the fluid flow holes. At point 3 C, the tip of the flange (128) has about 174 of the fluid flow holes. The point is moving through the orifice (116) as it decreases.

At the time of lighting, the impeller (122) is fully moved into the orifice (116). It moves to cut approximately half of the fluid flow.

At point E, the flange (128) of the impeller (122) 374 of the millimeter 116.

At point F, the flange (128) reduces the fluid flow hole to approximately its lowest pressure. It has moved sufficiently through the orifice (116) to cause .

Finally, at point G, the flange (128) of the impeller (122) is completely and the fluid moves into the orifice (116) on each side (128) of the flange (128). Block the fluid flow to the lowest state so that it can pass only on the 32) and (134) sides. are doing.

Therefore, the pressure of the fluid varies between the maximum pressure point and the minimum pressure point, and vice versa. and the maximum pressure point, it changes periodically, with changes occurring gradually.

As explained previously, the pressure of the fluid suddenly decreases to 0 pressure and then suddenly reaches the maximum pressure. As the pulsating jet stream increases to This is extremely important because it will occur.

Furthermore, the motor (102) rotates at 400 rpm, and the impeller (122) (124) is in a figure-eight configuration, the flange of each impeller is In one rotation, the resulting cleaning fluid passes through its output orifice twice. , the pressure is changed 800 times per minute, and the motor speed is 60 Orr. If the pm increases, the pressure of the cleaning fluid increases by 1 per minute from the maximum value to the minimum value. Can be changed 200 times. This action occurs when the water is pulsed or from zero pressure to Irritating to the skin when brought to maximum pressure.

The pressure is changed gradually, from maximum pressure to minimum pressure, without violent discharge pressure. According to the present invention, the skin can be cleaned of dust and bacteria present in the follicles and skin wrinkles. It undergoes compression and decompression, which is effective for There will be no stimulant effect.

One of the impellers (122) is shown in FIG. 124'l is constructed in a similar manner.

The impeller (122) has an upper flange (128) and a lower flange (130). It has an overall figure-eight shape.

Each end (136) of the upper flange (128) and each end of the lower flange (130) (138) is cut at an angle to form a point (140) as shown in Figure 12. has been done.

As previously explained, this causes one end of the impeller to be positioned at its output orifice. The first end gradually enters the orifice, shuts off the pressure, and then the other end gradually leaves the orifice. to restore the pressure and create a cyclically varying pressure, rather than a "pulsating" pressure. Rather, it creates a pressure that fluctuates periodically.

The millimeter (142) is connected to the motor (102) by a belt. This is for inserting the drive shaft (112).

The orifice (144) is a unit with a set screw or other type of foot, and is attached to the impeller. - (122) can be attached to the shaft (112).

The width of the flange (12g) completes the output orifice (116) shown in Figure 10. The value is such that there is no blockage at all. The closed area of the output orifice and the open area The preferred ratio of area in the state has been found to be 82% to 18%. this is , when the impeller flange closes the discharge opening to its maximum value, the output orifice 82% of the output orifice (116) is closed, at which point the output orifice (116) is closed. That means 18% will remain open.

This results in approximately 442.2 m/min when the orifice is fully open. liters (117 gallons) can be transferred through the output orifice, approximately 8 gallons per minute. 6 liters (20 gallons) can flow in its half-closed position. Therefore, fluid pressure is a cycle from maximum to minimum pressure value that changes gradually between two pressure limit values. change.

The minimum pressure that should be tolerated is the one that cleans the skin without causing skin irritation and , which is a value that allows for sufficiently quiet operation of this device. The disadvantage of both is that If the body is pulsed or totally blocked, then it is pulsed sharply. occurs in

From approximately the midpoint regarding point (138) to the midpoint regarding the other point (1311) and from the midpoint regarding (136) to the other end (136). The length of flanges (128) and (130) to the midpoint is approximately 67°.

On the other hand, the corresponding open area between the two ends (128) and (130) is approximately It is 113°. This will cause the output valve to have a significantly longer length than when it is closed. The arms and hands are open for a significant amount of time while cleaning at maximum pressure. It means to be happy.

FIG. 14 is a side view of the impeller (122).

FIG. 15 is a front view of the rubber sleeve (23) illustrated in FIGS. (7o), a truncated cone (146) and a depression or groove (76) at its end. include.

Figure 16 shows that the installation flange (24) shown in Figure 1 is fitted with a rubber sleeve. The cross-section shows how the sleeve looks when placed in place.

The sleeve has a flange (7o) placed in the recess (148) and Over the recess is a sealing ring (15) held in place by a screw (152). 0) is installed. The flange (70) is slightly thicker than the recess.

The flange (70) is made of amber white Amtex latex rubber component number 150. Since it is made of rubber such as 30, it is held securely in place.

The rubber sleeve (28) has an indentation ( It has a truncated cone (146) terminating at point 76). This structure is hygienic For the above purpose, it is extremely important. Place your entire arm inside the rubber sleeve. When accessing the inside of the sanitary device, the recess (76) is made of rubber; Due to its elastic nature, it is suitable for use.

As can be seen from FIG. 3, the nozzle (74) directs the cleaning fluid during the cleaning operation. toward the inner surface of the rubber sleeve (28). When pulling out the arm, the recess (76) Hold the rubber sleeve securely around the bowl so that the inner side of the sleeve is removed when the bowl is pulled out. Pull it to the side.

Turn the inside of the rubber sleeve completely outward until the arm is removed from the rubber sleeve. Once removed, only the disinfected inner surface of the rubber sleeve (28) will be cleaned and cleaned. comes into contact with the corresponding part of the Therefore, the arms are cleansed.

Any part of the equipment that is not clean or that may contain germs. It will not be exposed.

Accordingly, the nine indentations (76) illustrated in Figure 16 allow the arm and hand to be removed from the rubber sleeve. While being removed, any contact with the disinfected inner surface of the rubber sleeve (28) cleansed arms and hands to prevent contamination. The U-shaped recess (76) is To allow arms of different sizes to fit loosely within a rubber sleeve. rubber pickpocket The tube is flexible and can be dented, so it prevents blood flow from stopping in cases of thick arms. To prevent.

As shown in Figure 1, a timer is provided inside the electric control panel (22). . This timer can be set to a predetermined time, for example 90 seconds. Also, in advance The unit automatically shuts off after a set time has elapsed.
