[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] During the operation, a large amount of waste liquid is generated. The waste liquid contains substances such as washing solution, blood and body fluids. During traditional surgery, the liquid usually flows directly to the ground or is collected in a trash can and then dumped in a unified manner. During the process, the liquid is continuously exposed to the air and can become a source of infection, increasing the risk of infection for patients and staff in the operating room and affecting the safe operation of equipment in the operating room.

[0033] To this end, the embodiment of the utility model designs a waste liquid collection box 100 that can collect waste liquid generated during the operation and is connected to a negative pressure suction device to timely and effectively collect waste liquid generated during the operation, thereby preventing the waste liquid from being exposed to the air for a long time, thereby improving the safety of the operation.

[0034] The following describes a waste fluid collection box 100 for surgery according to an embodiment of the present invention with reference to the accompanying drawings.

[0035] like Figure 1-Figure 4 As shown, the waste liquid collection box 100 for surgery according to the embodiment of the utility model includes: a box body 1 and an upper cover 2.

[0036] The box body 1 defines a liquid storage space 11 with an upper opening 12. The box body 1 can receive the waste liquid flowing down from the bottom to prevent the waste liquid from flowing to the ground. The waste liquid generated during the operation can be collected in the liquid storage space 11 and wait for the next treatment.

[0037] A drain port 1311 connected to the negative pressure suction device is provided on the box body 1, so that the negative pressure suction device can timely and effectively collect the waste liquid generated during the operation, avoid the waste liquid from being exposed to the air for a long time, reduce the risk of infection for patients and staff in the operating room, facilitate postoperative waste disposal, and ensure the safe operation of equipment in the operating room.

[0038] The upper opening 12 of the liquid storage space 11 is covered with an upper cover 2. On the one hand, the upper cover 2 can cover the upper opening 12 of the liquid storage space 11. The upper cover 2 has a certain supporting ability. During the operation, the staff in the operating room can step on the upper cover 2 to avoid the setting of the waste liquid collection box 100 affecting the normal movement of the doctor in the operating room and affecting the doctor's operating angle.

[0039] On the other hand, a filter element 21 is provided on the upper cover 2. The setting of the transition element can isolate the liquid storage space 11 from the external space, preventing items in the operating room from falling into the liquid storage space 11 and causing loss of items. It can also isolate impurities contained in the liquid, such as hair, etc., to prevent impurities from clogging the drain port 1311 and affecting the collection and discharge of waste liquid.

[0040] According to the waste liquid collection box 100 for surgery in the embodiment of the utility model, the waste liquid collection box 100 for surgery can timely and effectively collect waste liquid generated during the operation, avoid the waste liquid collection box 100 being exposed to the air for a long time, and improve the safety of the operation.

[0041] like Figure 1 and Figure 2 As shown, in order to further ensure the strength of the upper cover 2 and ensure that the upper cover 2 and the waste liquid collection box 100 as a whole can stably support a person standing or stepping on the upper cover 2, a plurality of support members 4 are provided in the liquid storage space 11. The support members 4 are supported and arranged between the bottom wall 17 of the box body 1 and the upper cover 2 to support the upper cover 2 to prevent the middle part of the upper cover 2 from being deformed and stressed when being stepped on, thereby causing damage to the upper cover 2.

[0042] The support member 4 can be formed into a variety of different forms. In some embodiments, refer to Figure 1 The support member 4 can be formed as a support column supported between the upper cover 2 and the bottom wall 17. In other embodiments, the support member 4 can also be formed as a support rib supported between the upper cover 2 and the bottom wall 17.

[0043] Reference Figure 1 and Figure 2When the upper cover 2 is subjected to force, the corresponding positions of the upper cover 2 and the support member 4 are locally subjected to greater force. In order to ensure that the contact between the upper cover 2 and the support member 4 is not damaged by force, a reinforcing structure 22 is provided at the corresponding positions of the upper cover 2 and the support member 4, and the filter member 21 is arranged around the reinforcing structure 22 to ensure the strength of the contact between the support member 4 and the upper cover 2 without affecting the liquid passing through the upper cover 2 into the liquid storage space 11 and the arrangement of the filter member 21, thereby ensuring that the waste liquid collection box 100 can stably withstand the trampling of the staff.

[0044] Reference Figure 1 and Figure 2 In order to ensure that the liquid can be stably discharged through the drain port 1311, the bottom wall 17 of the liquid storage space 11 is tilted downward in the direction close to the drain port 1311. Thus, the liquid entering the liquid storage space 11 can stably flow to the drain port 1311 under the action of gravity and be discharged through the drain port 1311, thereby preventing the liquid from being retained on the bottom wall 17 of the liquid storage space 11, causing the liquid to be exposed to the air for a long time and affecting the health of people in the operating room.

[0045] In some embodiments, Figure 1 As shown, at least a portion of the side wall of the box body 1 is formed as a transparent observation window 5 for observing the liquid level inside the liquid storage space 11. The staff in the operating room can directly observe the liquid level in the liquid storage space 11 through the transparent observation window 5 to determine whether the liquid content is too much, and when the liquid level is too high, determine whether there is a pipeline blockage, or whether to choose to increase the suction power of the negative pressure suction device.

[0046] In some embodiments, the box body 1 may be made of a transparent material, such as a transparent acrylic material, and thus, there is no need to separately open a transparent observation window 5 on the box body 1 .

[0047] Among them, scale lines can be set at the transparent observation window 5 to more intuitively judge the liquid content in the liquid storage space 11.

[0048] The bottom wall 17 of the liquid storage space 11 is tilted downward in the direction close to the drain port 1311. In order to ensure the observation effect of the transparent observation window 5 and avoid the occurrence of a blind spot at the transparent observation window 5, the transparent observation window 5 is at least partially arranged close to the drain port 1311, so that the observation span of the transparent observation window 5 in the height direction is larger. The transparent observation window 5 covers the bottom and the top of the box body 1 in the vertical direction, ensuring the liquid level range that can be observed at the transparent observation window 5.

[0049] Reference Figure 1 , Figure 2 and Figure 4A water suction pipe 13 is provided on the first side wall 15 of the box body 1. The water suction pipe 13 passes through the box body 1 and is connected to the inner and outer sides of the liquid storage space 11. The negative pressure suction device is connected to the water suction pipe 13. The liquid in the liquid storage space 11 is sucked through the water suction pipe 13. The water suction pipe 13 is integrally formed with the box body 1 to avoid leakage at the connection between the suction pipe and the box body 1, causing liquid to leak on the ground and affect the safety of the operation.

[0050] Among them, the inlet of the water suction pipe 13 faces downward and is spaced apart from the bottom wall 17 of the box body 1. The inlet is formed as a drain outlet 1311. On the one hand, due to the spacing between the water suction pipe 13 and the bottom wall 17, large solid impurities can sink to the bottom, preventing large solid impurities from entering the water suction pipe 13 and clogging the pipeline, and facilitating the cleaning of the waste liquid collection box 100.

[0051] On the other hand, the inlet of the suction pipe 13 faces downward and is parallel to the liquid surface. The negative pressure suction device can only suck the liquid when the liquid surface is above the drain outlet 1311, thereby reducing the noise generated when absorbing the liquid and ensuring the efficiency of absorbing the liquid.

[0052] In some embodiments, a filtering structure is provided at the inlet of the water suction pipe 13 to further prevent the water suction pipe 13 from being unobstructed and clogging.

[0053] like Figure 1 , Figure 2 and Figure 3 As shown, the water extraction pipe 13 also includes a joint 132, which is arranged outside the liquid storage space 11 and is used to communicate with the negative pressure suction device. By setting the joint 132, the stability of the connection between the water extraction pipe 13 and the negative pressure suction device can be ensured to avoid leakage at the connection. The detachable connection between the negative pressure suction device and the joint 132 is also convenient for disconnecting the negative pressure suction device from the waste liquid collection box 100 when there is no need to collect liquid, and conveniently moving the waste liquid collection box 100 when the waste liquid collection box 100 is not in use.

[0054] Among them, the water suction pipe 13 is arranged on the first side wall 15 of the box body 1. Since the inlet of the water suction pipe 13 is formed as a drain port 1311, the bottom wall 17 of the liquid storage space 11 extends downwardly inclined in the direction close to the drain port 1311. In order to avoid interference between the setting of the water suction pipe 13 and the bottom wall 17, the bottom wall 17 of the liquid storage space 11 is arranged downwardly inclined in the direction close to the water suction pipe 13.

[0055] In some embodiments, in order to facilitate the opening of the transparent observation window 5 and better ensure the capacity of the liquid storage space 11, the suction pipe 13 is arranged close to the second side wall 16 adjacent to the first side wall 15. At this time, the bottom wall 17 includes a first part extending downwardly inclined toward the first side wall 15, a second part extending downwardly inclined toward the second side wall 16, and a third part located below the drain outlet 1311, and the third part extends in a horizontal direction.

[0056] The third part is located at the junction of the first side wall 15 and the second side wall 16. The best position for the transparent observation window 5 to observe the water level is the water level above the third part. Therefore, a transparent observation window 5 is provided on the side of the second side wall 16 close to the first side wall 15 to ensure the comprehensiveness of the observation through the transparent observation window 5.

[0057] Reference Figure 1 and Figure 2 The waste liquid collection box 100 also includes: a moving wheel 6, which is arranged on one side of the box body 1 in the length direction and is rotatably connected to the box body 1. Through the arrangement of the moving wheel 6, the box body 1 can be conveniently moved before and after the operation, reducing the workload of medical staff.

[0058] Among them, the moving wheels 6 do not protrude from the bottom surface of the box body 1 when the box body 1 is placed horizontally, so as to avoid the setting of the moving wheels 6 affecting the stability of the box body 1 when it is placed horizontally. When medical staff step on the waste liquid collection box 100, the box body 1 has sufficient stability to ensure the safety of medical staff's operation and improve safety.

[0059] Furthermore, anti-skid parts may be provided at the bottom of the box body 1, such as additional protrusions, anti-skid pads, etc., to further ensure the stability of the box body 1 when it is placed horizontally.

[0060] In some embodiments, the bottom wall 17 of the liquid storage space 11 extends downwardly from one side to the other side in the length direction of the box body 1, and the moving wheel 6 can be arranged on one side in the length direction of the box body 1. A handle 7 is provided on the other side in the length direction of the box body 1. Part of the structure of the moving wheel 6 can be hidden under the inclined surface of the bottom wall 17 of the liquid storage space 11 to reduce the space occupied by the moving wheel 6.

[0061] A handle 7 is provided on the other side of the box body 1 so that the staff can rotate and move the box body 1 through the handle 7, which is convenient for the staff to operate.

[0062] Reference Figure 1-Figure 3The opening 12 of the box body 1 has a supporting surface 14 that is inclined downward from the outside to the inside, and the edge of the upper cover 2 has a matching surface 23, and the matching surface 23 is stop-fitted with the supporting surface 14. On the one hand, the matching of the supporting surface 14 and the matching surface 23 can stably support the upper cover 2 at the opening 12 to prevent the upper cover 2 from collapsing at the opening 12. On the other hand, setting the opening 12 of the box body 1 to be inclined downward from the outside to the inside can also guide the liquid. When the liquid splashes at the opening 12 of the box body 1, the liquid can gather in the liquid storage space 11 under the action of gravity, thereby ensuring the effect of collecting waste liquid in the waste liquid collection box 100.

[0063] Reference Figure 1 The waste liquid collection box 100 also includes: a liquid level sensor 3, which is used to detect the liquid level height inside the liquid storage space 11.

[0064] Among them, in some embodiments, the liquid level sensor 3 communicates with the negative pressure suction device, and the negative pressure suction device starts to operate when the liquid level height inside the liquid storage space 11 reaches a first preset height, and the negative pressure suction device stops operating when the liquid level height inside the liquid storage space 11 reaches a second preset height. The second preset height is lower than the first preset height, and the height of the drain outlet 1311 is lower than the second preset height.

[0065] That is to say, during the operation of the waste liquid collection box 100, the liquid level inside the waste liquid collection box 100 rises until the liquid level exceeds the drain outlet 1311 and reaches the first preset height. After the liquid level reaches the first preset height, the liquid level sensor 3 collects the information that the liquid level reaches the first preset height, and controls the negative pressure suction device to start, so as to suck out the liquid stored in the liquid storage space 11. Since the negative pressure suction device is started and operated after the liquid level reaches the first preset height, the idling of the negative pressure suction device is avoided, thereby reducing noise and energy consumption.

[0066] When the negative pressure suction device starts to suck the liquid in the liquid storage space 11, and no liquid from the outside is collected in the waste liquid collection box 100, the liquid level in the liquid storage space 11 drops until the liquid level drops to the second preset height. After the liquid level reaches the second preset height, the liquid level sensor 3 collects information that the liquid level reaches the second preset height, and controls the negative pressure suction device to stop running, thereby avoiding idling of the negative pressure suction device and reducing noise and energy consumption.

[0067] In some embodiments, the liquid level sensor 3 also communicates with the alarm device, and issues an alarm when the liquid level inside the liquid storage space 11 reaches a third preset height. When a pipeline is blocked or the suction volume of the negative pressure suction device is lower than the waste liquid generation volume, the liquid level in the waste liquid collection box 100 continues to rise, causing a risk of liquid overflow. After the liquid level reaches the third preset height, the liquid level sensor 3 collects information that the liquid level reaches the third preset height, and controls the alarm device to sound an alarm. The staff can increase the suction power of the negative pressure suction device or eliminate blockages based on the alarm information to prevent the liquid from overflowing onto the ground and improve safety.

[0068] Reference Figure 3 The edge of the opening 12 is protruding from the upper cover 2 to prevent the liquid from flowing to the ground under the tension of the liquid itself when the filter 21 is blocked by too much liquid and the liquid does not have time to pass through the filter 21 to enter the liquid storage space 11. The edge of the opening 12 and the upper cover 2 define a certain space to temporarily accumulate some liquid, leaving a certain amount of time for the liquid to enter the liquid storage space 11.

[0069] A specific embodiment of the waste liquid collection box 100 for surgery of the present invention will be described below with reference to the accompanying drawings.

[0070] like Figure 1-Figure 4 As shown, the waste liquid collection box 100 for surgery provided according to the embodiment of the utility model includes: a box body 1, an upper cover 2, a liquid level sensor 3, moving wheels 6 and a handle 7.

[0071] The box body 1 defines a liquid storage space 11 with an upper opening 12. The box body 1 can receive the waste liquid flowing down from the bottom to prevent the waste liquid from flowing to the ground. The waste liquid generated during the operation can be collected in the liquid storage space 11 and wait for the next treatment. The upper opening 12 of the liquid storage space 11 is covered with an upper cover 2. On the one hand, the upper cover 2 can cover the upper opening 12 of the liquid storage space 11. The upper cover 2 has a certain supporting capacity. During the operation, the staff in the operating room can step on the upper cover 2 to prevent the setting of the waste liquid collection box 100 from affecting the normal movement of the doctor in the operating room and affecting the doctor's operating angle.

[0072] On the other hand, a filter element 21 is provided on the upper cover 2. The setting of the transition element can isolate the liquid storage space 11 from the external space, preventing items in the operating room from falling into the liquid storage space 11 and causing loss of items. It can also isolate impurities contained in the liquid, such as hair, etc., to prevent impurities from clogging the drain port 1311 and affecting the collection and discharge of waste liquid.

[0073] In order to further ensure the strength of the upper cover 2 and ensure that the upper cover 2 and the waste liquid collection box 100 as a whole can stably support people standing or stepping on the upper cover 2, a plurality of support members 4 are provided in the liquid storage space 11. The support members 4 are supported and arranged between the bottom wall 17 of the box body 1 and the upper cover 2 to support the upper cover 2 to prevent the middle part of the upper cover 2 from being deformed and stressed when being stepped on, causing damage to the upper cover 2. The support members 4 are formed as support columns supported and arranged between the upper cover 2 and the bottom wall 17. A reinforcement structure 22 is provided at the corresponding position of the upper cover 2 and the support member 4, and the filter member 21 is arranged around the reinforcement structure 22 to ensure the strength of the contact between the support member 4 and the upper cover 2 without affecting the liquid entering the liquid storage space 11 through the upper cover 2 and the arrangement of the filter member 21, so as to ensure that the upper part of the waste liquid collection box 100 can stably withstand the stepping of the staff.

[0074] A water suction pipe 13 is provided on the first side wall 15 of the box body 1. The water suction pipe 13 passes through the box body 1 and is connected to the inner and outer sides of the liquid storage space 11. The negative pressure suction device is connected to the water suction pipe 13. The liquid in the liquid storage space 11 is sucked through the water suction pipe 13. The water suction pipe 13 and the box body 1 are integrally formed to avoid leakage at the connection between the suction pipe and the box body 1, causing liquid to leak onto the ground and affect the safety of the operation.

[0075] Among them, the inlet of the water suction pipe 13 faces downward and is spaced apart from the bottom wall 17 of the box body 1. The inlet is formed as a drain outlet 1311. On the one hand, due to the spacing between the water suction pipe 13 and the bottom wall 17, large solid impurities can sink to the bottom, preventing large solid impurities from entering the water suction pipe 13 and clogging the pipeline, and facilitating the cleaning of the waste liquid collection box 100.

[0076] On the other hand, the inlet of the suction pipe 13 faces downward and is parallel to the liquid surface. The negative pressure suction device can only suck the liquid when the liquid surface is above the drain outlet 1311, thereby reducing the noise generated when absorbing the liquid and ensuring the efficiency of absorbing the liquid.

[0077] A filtering structure is provided at the inlet of the water pumping pipe 13 to further prevent the water pumping pipe 13 from being unobstructed and from being blocked.

[0078] The water extraction pipe 13 includes a water guide 131 and a joint 132. The joint 132 is arranged outside the liquid storage space 11 and is used to communicate with the negative pressure suction device. By setting the joint 132, the stability of the connection between the water extraction pipe 13 and the negative pressure suction device can be ensured to avoid leakage at the connection. The detachable connection between the negative pressure suction device and the joint 132 is also convenient for disconnecting the negative pressure suction device from the waste liquid collection box 100 when there is no need to collect liquid, and conveniently moving the waste liquid collection box 100 when the waste liquid collection box 100 is not in use.

[0079] In some embodiments, in order to facilitate the opening of the transparent observation window 5 and better ensure the capacity of the liquid storage space 11, the suction pipe 13 is arranged close to the second side wall 16 adjacent to the first side wall 15. At this time, the bottom wall 17 includes a first part extending downwardly inclined toward the first side wall 15, a second part extending downwardly inclined toward the second side wall 16, and a third part located below the drain outlet 1311, and the third part extends in a horizontal direction.

[0080] The third part is located at the junction of the first side wall 15 and the second side wall 16. The best position for the transparent observation window 5 to observe the water level is the position of the water level above the third part. Therefore, a transparent observation window 5 is provided on one side of the second side wall 16 close to the first side wall 15 to ensure the comprehensiveness of the observation of the transparent observation window 5. Graduation lines can be set at the transparent observation window 5 to more intuitively judge the liquid content in the liquid storage space 11.

[0081] The moving wheels 6 are arranged at one side of the box body 1 in the length direction and are rotatably connected to the box body 1. By setting the moving wheels 6, the box body 1 can be conveniently moved before and after the operation, reducing the workload of medical staff.

[0082] Among them, the moving wheels 6 do not protrude from the bottom surface of the box 1 when the box 1 is placed horizontally. Furthermore, anti-slip parts can be set at the bottom of the box 1, such as adding bumps, anti-slip pads, etc., to further ensure the stability of the box 1 when it is placed horizontally.

[0083] The bottom wall 17 of the liquid storage space 11 extends downwardly from one side to the other side in the length direction of the box body 1, and the side wall on the other side in the length direction of the box body 1 is the first side wall 15. The moving wheel 6 can be arranged on one side in the length direction of the box body 1, and a handle 7 is provided on the other side in the length direction of the box body 1. Part of the structure of the moving wheel 6 can be hidden under the inclined surface of the bottom wall 17 of the liquid storage space 11 to reduce the space occupied by the moving wheel 6.

[0084] A handle 7 is provided on the other side of the box body 1 so that the staff can rotate and move the box body 1 through the handle 7, which is convenient for the staff to operate.

[0085] In some embodiments, the box 1 is not provided with moving wheels 6, and only a handle is provided on one side in the width direction. When in use, the handle can be directed toward the operating bed to avoid the handle affecting the movement of medical staff. Medical staff can also move the box 1 conveniently by pulling the handle, thereby improving convenience.

[0086] The opening 12 of the box body 1 has a support surface 14 that slopes downward from the outside to the inside, and the edge of the upper cover 2 has a matching surface 23, which is abutted against the support surface 14. The edge of the opening 12 is convex from the upper cover 2 to prevent the liquid from flowing to the ground under the tension of the liquid itself when the filter 21 is blocked by too much liquid and the liquid does not have time to pass through the filter 21 to enter the liquid storage space 11. The edge of the opening 12 and the upper cover 2 define a certain space to temporarily accumulate some liquid, leaving a certain amount of time for the liquid to enter the liquid storage space 11.

[0087] In some embodiments, the upper cover 2 is placed above the box body 1, and there is no connection between the upper cover 2 and the box body 1, so that medical staff can pick up the upper cover 2 to clean it when there are too many impurities on the upper cover 2. Alternatively, the upper cover 2 and the box body 1 are detachably connected by means of a snap connection, so that the two can move together.

[0088] The waste liquid collection box 100 further includes a liquid level sensor 3 , which is used to detect the liquid level height inside the liquid storage space 11 .

[0089] Among them, in some embodiments, the liquid level sensor 3 communicates with the negative pressure suction device, and the negative pressure suction device starts to operate when the liquid level height inside the liquid storage space 11 reaches a first preset height, and the negative pressure suction device stops operating when the liquid level height inside the liquid storage space 11 reaches a second preset height. The second preset height is lower than the first preset height, and the height of the drain outlet 1311 is lower than the second preset height.

[0090] That is to say, during the operation of the waste liquid collection box 100, the liquid level inside the waste liquid collection box 100 rises until the liquid level exceeds the drain outlet 1311 and reaches the first preset height. After the liquid level reaches the first preset height, the liquid level sensor 3 collects the information that the liquid level reaches the first preset height, and controls the negative pressure suction device to start, so as to suck out the liquid stored in the liquid storage space 11. Since the negative pressure suction device is started and operated after the liquid level reaches the first preset height, the idling of the negative pressure suction device is avoided, thereby reducing noise and energy consumption.

[0091] When the negative pressure suction device starts to suck the liquid in the liquid storage space 11, and no liquid from the outside is collected in the waste liquid collection box 100, the liquid level in the liquid storage space 11 drops until the liquid level drops to the second preset height. After the liquid level reaches the second preset height, the liquid level sensor 3 collects information that the liquid level reaches the second preset height, and controls the negative pressure suction device to stop running, thereby avoiding idling of the negative pressure suction device and reducing noise and energy consumption.

[0092] The liquid level sensor 3 also communicates with the alarm device, and issues an alarm when the liquid level in the liquid storage space 11 reaches the third preset height. When the pipeline is blocked or the suction volume of the negative pressure suction device is lower than the waste liquid generation volume, the liquid level in the waste liquid collection box 100 continues to rise, causing the risk of liquid overflow. After the liquid level reaches the third preset height, the liquid level sensor 3 collects the information that the liquid level reaches the third preset height, and controls the alarm device to sound an alarm. The staff can increase the suction power of the negative pressure suction device or eliminate the blockage according to the alarm information to prevent the liquid from overflowing to the ground and improve safety.

[0093] In some embodiments, the waste liquid collection box 100 is 60 cm long, 30 cm wide, and 10 cm high. The height difference between the highest point and the lowest point of the bottom wall of the liquid storage space 11 is 2 cm. The waste liquid collection box 100 of this size can meet the needs of receiving surgical waste liquid without affecting the operator's operation.

[0094] In other embodiments, the length, width and height of the waste liquid collection box 100 can adopt a variety of different size combinations to meet the different needs of different surgeries, which is not limited here.
