Description

Technical Field

[0002] The operating room is a place where patients undergo surgery and emergency treatment, and is an important technical department of the hospital. Generally speaking, water is used frequently in the operating room, such as for sterile treatment before surgery and flushing of instruments after surgery. Therefore, the water supply system is very important in the construction of the operating room, and there are many corresponding requirements for the water supply system.

[0003] When constructing the operating room water supply system, multiple water supply channels and timely supply of hot and cold water should be considered; multiple water supply channels are to avoid water shortages in the operating room due to water source failures and no backup water source, and timely supply of hot and cold water is to facilitate the use of medical staff. A common way to replace the water source of multiple water supply channels is with intelligent monitoring electric valves.

[0042] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0043] See also Figure 1 to Figure 8 As an embodiment of the utility model, the hot and cold water supply system for the operating room includes a water supply pipeline 1, and a heating water tank 2 and a spare water tank 3 arranged on the water supply pipeline 1; a hot water pipeline 5 is fixedly connected to the heating water tank 2, and the water supply pipeline 1 and the spare water tank 3 are both fixedly connected to a cold water pipeline 4;

[0044] The heating water tank 2 is fixedly provided with a first water inlet valve 201 fixedly connected to the water supply pipeline 1; the standby water tank 3 is fixedly provided with a first water outlet valve 301, and the first water outlet valve 301 is fixedly connected with a second water inlet valve 202 fixedly provided on the heating water tank 2;

[0045] A switching mechanism is provided in the heating water tank 2, and the switching mechanism can close the second water inlet valve 202 when the first water inlet valve 201 is opened, or open the second water inlet valve 202 when the first water inlet valve 201 is closed.

[0046] In this embodiment, the water supply pipeline 1 provides low-temperature water to the operating room through the cold water pipeline 4. The water supply pipeline 1 provides water to the heating water tank 2 through the first water inlet valve 201, and the water is heated in the heating water tank 2, and provides high-temperature water to the operating room through the hot water pipeline 5.

[0047] The standby water tank 3 provides low-temperature water to the operating room through the cold water pipeline 4. The standby water tank 3 provides water to the heating water tank 2 through the first water outlet valve 301 and the second water inlet valve 202. Then, the water is heated in the heating water tank 2 and provided to the operating room through the hot water pipeline 5.

[0048] That is, there are two water supply pipelines to provide water to the operating room, namely: water supply pipeline 1 and spare water tank 3.

[0049] Under normal circumstances, the water supply line 1 is used as the main water supply source for water use in the operating room. At this time, the water pressure in the water supply line 1 will open the first water inlet valve 201 and let water flow into the heating water tank 2; under the action of the switching mechanism, the second water inlet valve 202 will remain closed to prevent the standby water tank 3 from entering the heating water tank 2; when the water supply line 1 fails, the water pressure will not open the first water inlet valve 201. At this time, the switching mechanism will open the second water inlet valve 202, so that the water in the standby water tank 3 can enter the heating water tank 2 to be supplied to the operating room.

[0050] The water supply source in the operating room is switched by the switching mechanism. Since the switching mechanism is controlled according to the water pressure, when the water supply pipeline 1 fails, the water supply source can be switched promptly and quickly, avoiding water shortage in the operating room due to untimely replacement of the water source.

[0051] As a further solution of the utility model, a third water inlet valve 303 is fixedly installed on the standby water tank 3, and the third water inlet valve 303 is fixedly connected to the water supply pipeline 1; a second water outlet valve 302 is fixedly installed on the standby water tank 3 and is fixedly connected to the cold water pipeline 4, and the cold water pipeline 4 is fixedly connected to the water supply pipeline 1; a hot water outlet valve 203 is fixedly installed on the heating water tank 2 and is fixedly connected to the hot water pipeline 5.

[0052] In this embodiment, the water supply pipeline 1 will flow water into the standby water tank 3 through the third water inlet valve 303 until the standby water tank 3 is full. When the standby water tank 3 is used as a water supply source, water will be supplied to the cold water pipeline 4 through the second water outlet valve 302, and water will be supplied to the heating water tank 2 through the first water outlet valve 301 and the second water inlet valve 202. The water heated in the heating water tank 2 will be supplied to the hot water pipeline 5 through the hot water outlet valve 203.

[0053] As a further solution of the utility model, the switching mechanism includes a first support rod 13 and a second support rod 14 fixed on the heating water tank 2; a first piston 11 that can be slidably engaged with the first water inlet valve 201 is slidably mounted on the first support rod 13, a first baffle 1301 is fixedly mounted on the first support rod 13, and a first return spring 1302 that is fixedly connected to the first baffle 1301 and the first piston 11 is also movably mounted on the first support rod 13;

[0054] The second support rod 14 is slidably mounted with a second piston 12 that can be slidably engaged with the second water inlet valve 202, the second support rod 14 is fixedly mounted with a second baffle 1401, and the second support rod 14 is also movably mounted with a second return spring 1402 that is fixedly connected to the second baffle 1401 and the second piston 12;

[0055] A connecting rod 10 is rotatably mounted on the first piston 11 , and the connecting rod 10 is rotatably mounted on the second piston 12 .

[0056] In this embodiment, in the initial state, the first piston 11 is located inside the first water inlet valve 201, and the second piston 12 is located inside the second water inlet valve 202. The water pressure in the water supply line 1 is greater than the water pressure in the standby water tank 3.

[0057] When the water supply line 1 is used as a water supply source, the water pressure in the water supply line 1 pushes the first piston 11 to slide on the first support rod 13, so that the first piston 11 is disengaged from the first water inlet valve 201, and the first water inlet valve 201 is opened. In this process, the first piston 11 slides toward the first baffle 1301 and compresses the first return spring 1302.

[0058] During the sliding process of the first piston 11, the angle between the connecting rod 10 and the first piston 11 gradually increases, so that the angle between the second piston 12 and the connecting rod 10 gradually decreases, thereby pushing the second piston 12 to slide away from the second baffle 1401 on the second support rod 14. At this time, the second piston 12 will further enter the second water inlet valve 202 and slide with it. After the second piston 12 further enters the second water inlet valve 202, it will block the second water inlet valve 202 and offset the water pressure in the standby water tank 3, thereby closing the second water inlet valve 202 to prevent the water in the standby water tank 3 from flowing into the heating water tank 2, causing the water level in the standby water tank 3 to drop, thereby affecting its use.

[0059] When the water supply pipeline 1 fails, the water pressure in the pipeline will disappear. At this time, the water pressure in the standby water tank 3 will push the second piston 12 to slide toward the second baffle 1401 and push it out of the second water inlet valve 202, so that the water in the standby water tank 3 can enter the heating water tank 2. During this process, the second piston 12 will compress the second return spring 1402, and the angle between the connecting rod 10 and the second piston 12 will gradually increase, thereby making the angle between the connecting rod 10 and the first piston 11 smaller and smaller, so that the first piston 11 can further enter the first water inlet valve 201, so as to prevent the water in the heating water tank 2 from seeping into the water supply pipeline 1.

[0060] As a further solution of the utility model, a heating mechanism is provided on the heating water tank 2, and the heating mechanism includes a heater 6 fixedly installed on the heating water tank 2, one end of the heater 6 is fixedly connected to a heating rod 601, and the other end thereof is fixedly connected to a conductive rod 602; a protective shell 7 fixedly connected to the heating water tank 2 is fixedly installed on the conductive rod 602, a sliding disk 8 is slidably installed on the conductive rod 602, and the sliding disk 8 is slidably engaged with the protective shell 7; a plurality of groups of first conductive protrusions 801 are fixedly installed on the sliding disk 8; a fixed disk 9 fixedly connected to the heating rod 601 is fixedly installed on the protective shell 7, and a plurality of groups of second conductive protrusions 901 are fixedly installed on the fixed disk 9.

[0061] In this embodiment, when the sliding disk 8 is located at the set position, the first conductive protrusion 801 will fit with the second conductive protrusion 901, so that a loop is formed between the heater 6, the heating rod 601 and the conductive rod 602, so that the heating rod 601 can generate heat under the control of the heater 6 to heat the water in the heating water tank 2, thereby providing higher temperature water to the operating room. When the temperature reaches the set value, the first conductive protrusion 801 will separate from the second conductive protrusion 901, thereby forming a short circuit to stop heating the water in the heating water tank 2.

[0062] As a further solution of the utility model, a temperature control mechanism cooperating with the heating mechanism is arranged in the protective shell 7, and the temperature control mechanism includes a plurality of slide grooves 802 provided on the sliding plate 8, a wedge block 804 is slidably engaged in the slide groove 802, and a resistance spring 803 fixedly connected to the wedge block 804 is movably installed in the slide groove 802;

[0063] The protective shell 7 is provided with a notch 701 which cooperates with the wedge block 804 .

[0064] In this embodiment, the sliding plate 8 and the protective shell 7 are tightly fitted and slidably matched, and there is no installation gap between the fixed plate 9 and the heating rod 601 and the protective shell 7. The space between the sliding plate 8 and the fixed plate 9 is filled with inert gas.

[0065] When the heating mechanism is working, the wedge block 804 is located in the notch 701, the temperature of the water in the heating water tank 2 will increase, thereby increasing the temperature of the inert gas. Under the action of thermal expansion and contraction, the inert gas will expand, thereby pushing the sliding plate 8 to slide on the conductive rod 602, thereby separating the first conductive protrusion 801 from the second conductive protrusion 901, so that the heating mechanism stops working. In addition, during the sliding process of the sliding plate 8, the notch 701 will cooperate with the wedge block 804, squeezing the wedge block 804 to make it slide inward in the slide groove 802, thereby compressing the resistance spring 803, and the elastic force of the resistance spring 803 is the main resistance to the sliding of the sliding plate 8. After the heating mechanism stops working, the water temperature in the heating water tank 2 will decrease, thereby shrinking the inert gas. At this time, the sliding plate 8 will slide toward the fixed plate 9 until the first conductive protrusion 801 fits with the second conductive protrusion 901, and the heating mechanism starts working again.

[0066] Through the cooperation between the heating mechanism and the temperature control mechanism, the operating room's demand for hot water can be guaranteed and energy consumption can be saved to the maximum extent.

[0067] As a further solution of the present invention, part of the heating rod 601 is wavy, and the outer surface of the heating rod 601 is coated with insulating paint.

[0068] In this embodiment, the wavy feature of the heating rod 601 can increase the contact area between the heating rod 601 and water, thereby conducting heat faster and increasing the water temperature in the heating water tank 2. The insulating coating can effectively avoid the risk of electric shock.

[0069] As a further solution of the present invention, the hot water outlet valve 203 and the second water outlet valve 302 are both one-way valves.

[0070] In this embodiment, in order to prevent the water in the heating water tank 2 and the standby water tank 3 from being contaminated, the hot water outlet valve 203 and the second water outlet valve 302 are configured as one-way valves, thereby avoiding water contamination.

[0071] The above embodiments are exemplary rather than restrictive, so without departing from the spirit or basic features of the present invention, the technical solutions of the present invention that can be implemented in other specific forms are all included in the present invention.
