DETAILED DESCRIPTION

[0032] Example, by Figure 1-11 The present invention includes a pedestal 1, a plurality of table panels 5 are installed on the top of the pedestal 1, the table panels 5 are composed of a left panel 51 and a right panel 52, a plug plate 8 is fixedly connected to the inner side of the left panel 51, a slot 9 is opened on the inner side of the right panel 52, the plug plate 8 is located inside the slot 9, the left panel 51 and the right panel 52 are plugged and connected through the plug plate 8 and the slot 9, the front and rear sides of the pedestal 1 are processed with extension plates 2, two connecting rods 3 are fixedly connected between the two extension plates 2, a cavity 6 is opened inside the left panel 51, the connecting rod 3 passes through the cavity 6, a plurality of elliptical sockets 7 are opened on the top of the left panel 51, a plurality of fixing belts 17 are installed above the pedestal 1, a funnel plate 22 is fixedly connected to the inside of the pedestal 1, and a sewage pipe 23 is fixedly connected at the bottom center of the funnel plate 22.

[0033] The left panel 51 is inserted into the slot 9 on the right panel 52 through the plug plate 8 to form a table panel 5. The plug plate 8 is inserted into the slot 9 with an interference fit, so that the left panel 51 and the right panel 52 will not be separated at will. The left panel 51 and the right panel 52 in the table panel 5 are respectively movably connected to the two connecting rods 3. The left panel 51 and the right panel 52 can be pulled left and right to separate the two. The opening of the cavity 6 prevents the left panel 51 and the right panel 52 from interfering with the connecting rod 3 and being unable to move. At the same time, after being separated, the left panel 51 and the right panel 52 can also be rotated along the connecting rod 3 to stand upright against the side of the table 1. At this time, the empty space above the table 1 can be used to clean wounds.

[0034] The left panel 51 and the right panel 52 in the table panel 5 are exactly the same in structure except for the plug-in plate 8 on the left panel 51 and the slot 9 on the right panel 52, such as the handle 20, the installed heating mechanism and various air ducts and embedded grooves adapted thereto, so the structure of the right panel 52 will not be described in detail here.

[0035] The shape of the funnel plate 22 allows the waste liquid that falls on the funnel plate 22 when cleaning the wound to flow to the drain pipe 23 in a centralized manner so as to be discharged through the drain pipe 23 .

[0036] A support mechanism is installed inside the pedestal 1, and the support mechanism is located above the funnel plate 22. The support mechanism includes a threaded rod 19, and the threaded rod 19 is movably connected to the inside of the pedestal 1 through a bearing. A T-shaped support seat 18 is installed on the threaded rod 19, and the T-shaped support seat 18 is located at the bottom of the center of one of the table panels 5. A handle 20 is fixedly connected to one end of the threaded rod 19, and the handle 20 is located in front of the pedestal 1.

[0037] The threaded rod 19 can be driven to rotate by rotating the handle 20, and the T-shaped support seat 18 can be moved horizontally along the threaded rod 19 when the threaded rod 19 rotates. When only one left panel 51 needs to be lifted, the remaining right panel 52 cannot remain in its original state. At this time, the T-shaped support seat 18 can be moved to press against the bottom of the right panel 52 to keep it horizontal to support the patient. This situation is generally used for cleaning wounds on the patient's limbs. When cleaning the torso, it is generally necessary to lift up the left panel 51 and the right panel 52 of a table panel 5 together. At this time, the T-shaped support seat 18 is not used, so it can be removed, which can prevent the T-shaped support seat 18 from contacting and pressing the patient, and can also prevent cleaning waste liquid from falling on the T-shaped support seat 18.

[0038] The T-shaped support seat 18 includes a support plate 181, and the T-shaped support seat 18 is located at the bottom of the connection between the left panel 51 and the right panel 52. The bottom of the support plate 181 is fixedly connected to a first connecting rod 182, and the bottom of the first connecting rod 182 is fixedly connected to a first sleeve 183, the first sleeve 183 is sleeved on the threaded rod 19, and the threaded rod 19 and the first sleeve 183 are threadedly connected. The support mechanism also includes a guide rod 21, and the guide rod 21 is fixedly connected to the inside of the pedestal 1, and the guide rod 21 is located between the threaded rod 19 and the funnel plate 22. The T-shaped support seat 18 also includes a second sleeve 185, and the second sleeve 185 is sleeved on the outer end of the guide rod 21, and the second sleeve 185 is slidably connected to the guide rod 21, and a second connecting block 184 is fixedly connected between the first sleeve 183 and the second sleeve 185.

[0039] The T-shaped support seat 18 is threadedly connected to the threaded rod 19 and is slidably connected to the guide rod 21, so that the T-shaped support seat 18 can maintain horizontal movement when moving without the problem of rotating together with the threaded rod 19.

[0040] The fixing belt 17 includes two straps 171 connected to each other by Velcro, and two T-shaped plugs 172 are fixedly connected to the bottom of the strap 171. The T-shaped plugs 172 pass through the adjacent elliptical holes 7 and extend into the cavity 6. The fixing belt 17 is snap-connected above the adjacent table panel 5.

[0041] The fixing belt 17 has different sizes, but the structure is exactly the same. They are used to bind and fix the patient's limbs and torso respectively. The small fixing belt 17 is used to fix the limbs, and the large fixing belt 17 is used to fix the torso. The two straps 171 in the fixing belt 17 are attached by Velcro, so it is easy to adjust the tightness and more convenient to use. It can also be used for patients of different body shapes. When in use, the T-shaped plug 172 at the bottom of the strap 171 can be first inserted horizontally into the hole 7 and penetrate into the cavity 6, and then the T-shaped plug 172 can be rotated ninety degrees. At this time, the T-shaped plug 172 can no longer pass through the hole 7, so that the fixing belt 17 can be clamped on the table panel 5, and the fixing belt 17 can be clamped at different positions on the table panel 5 according to needs.

[0042] The bottom of the cavity 6 is provided with an embedding groove 11, and a heating mechanism 12 is installed inside the embedding groove 11. A ventilation groove 15 is opened on the outside of the table panel 5, and a protective net 16 is fixedly connected inside the ventilation groove 15. A U-shaped air duct 13 is opened inside the table panel 5, and the embedding groove 11 is located inside the U-shaped air duct 13, and the U-shaped air duct 13 is connected to the embedding groove 11 and the ventilation groove 15 respectively. A plurality of connecting air ducts 14 are provided between the embedding groove 11 and the ventilation groove 15, and the U-shaped air duct 13 and the connecting air duct 14 are both located below the cavity 6. The heating mechanism 12 is provided with a heat-insulating The left panel 51 is composed of a plate 121, a heating plate 122 and a protective mesh cover 123, the heating plate 122 is fixedly connected to the top of the insulation plate 121, the protective mesh cover 123 is fixedly connected to the top of the insulation plate 121 by bolts, the heating plate 122 is located inside the protective mesh cover 123, the insulation plate 121 is located below the U-shaped air duct 13 and the connecting air duct 14, the handle 10 is fixedly connected to the outside of the left panel 51, the ventilation slot 15 is located below the handle 10, and the outer end of the connecting rod 3 is provided with a plurality of spacer sleeves 4, and the spacer sleeve 4 is located between two adjacent table panels 5.

[0043] The heating mechanism 12 is composed of a heat insulation plate 121, a heating plate 122 and a protective mesh cover 123, wherein the heating plate 122 is used to heat the air and provide a heat source, and the heat insulation plate 121 is used to install the heating plate 122, while preventing the heating plate 122 from directly contacting the table panel 5 to heat it, thereby preventing the table panel 5 from being directly heated to an excessively high temperature, and the protective mesh cover 123 can prevent foreign matter from falling directly on the heating plate 122, thereby providing higher safety.

[0044] The heating mechanism 12 mainly relies on heated air for heat radiation to heat the table panel 5 and the patient lying on the washing table. The rising hot air can heat the upper layer of the table panel 5 to a certain extent to improve the patient's comfort, and can also directly heat the patient through the jack 7. When the heating mechanism 12 heats the air, the hot air rises. Since the heating mechanism 12 is embedded in the groove 11, the U-shaped air duct 13, the connecting air duct 14 and the ventilation groove 15 can allow the cold air outside the washing table to enter the groove 11 for use by the heating mechanism 12, and the cold air used is the air outside the washing table, not the air inside the base 1. The air inside the base 1 may have an odor due to contact with the waste liquid on the funnel plate 22, while the cold air supplied from the outside has less odor and is relatively clean.

[0045] The protective net 16 in the ventilation slot 15 can prevent other foreign objects from being brought in when cold air flows in, thereby playing a protective role. The handle 20 can be used to pull the left panel 51 or the right panel 52. The spacer sleeve 4 is located between the front and rear adjacent table panels 5, so that there is a gap between the adjacent table panels 5 to prevent the table panels 5 from slightly moving when the patient lies on the washing table and causing the gap between the two table panels 5 to pinch the patient's skin. The edges and corners on the upper surface of the connection between the left panel 51 and the right panel 52 in the table panels 5 are also rounded, which has the same function of preventing the patient's skin from being pinched.

[0046] A controller 24 is fixedly connected to the front side of the pedestal 1 , and the heating plate 122 and the controller 24 are electrically connected.

[0047] The controller 24 can control the opening and closing of the heating plate 122 in the heating mechanism 12, and the controller 24 and the heating plate 122 as well as the power supply of the heating plate 122 are connected through wires, and this wire connection method is common knowledge, so the specific connection method and wire arrangement will not be described in detail here.

[0048] Working principle:

[0049] In a normal state, the left panel 51 and the right panel 52 of the table panel 5 are assembled together and installed above the table base 1, and the fixing belt 17 is also installed at the required position on the table panel 5 according to the needs. According to the different positions of the patient's wound, the cleaning operation is also different. If it is an arm or other part, it can be directly installed on the table panel 5 with two small fixing belts 17, and the left panel 51 or the right panel 52 located between the two fixing belts 17 can be opened. At this time, when the wound is cared for and cleaned, the cleaning waste liquid will directly fall on the table. The liquid is placed on the funnel plate 22 in the seat 1, and finally discharged through the drainage pipe 23. When the wound is located in the waist and abdomen or other parts of the body, the patient can lie on the washing table, and then use the large or large and small fixing belt 17 to bind the patient to the washing table, and at the same time, the table panel 5 corresponding to the wound is opened, that is, the left panel 51 and the right panel 52 are pulled apart, and finally rotated vertically to hang on the connecting rod 3 against the side of the seat 1. At this time, when cleaning the wound, the cleaning waste liquid will also directly fall on the funnel plate 22 and be discharged through the drainage pipe 23;

[0050] If it is winter or other times when the temperature is low, the heating plate 122 in the heating mechanism 12 can be started through the controller 24, and the heating mechanism can heat the air in the cavity 6. The hot air then rises to heat the top of the table panel 5 so that it is not too cold, and on the other hand, it passes through the oval socket 7 to directly warm the patient, thereby improving the patient's comfort.
