DETAILED DESCRIPTION

[0024] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0025] Example: Figure 1 As shown, the medical flushing and suction integrated device of this embodiment includes a mobile base 1, a controller 2, a bracket 3, a drainage device 4, a negative pressure device 5 and a flushing and drainage device 6. The mobile base 1 is equipped with an electronic weighing device 8 connected to the controller 2, and a column 11 is installed on the weighing surface of the electronic weighing device 8. The drainage device 4 and the negative pressure device 5 are respectively installed on the electronic weighing device 8. The controller 2 is installed on the upper end of the column 11, and the bracket 3 is installed on the side end of the controller 2. The bracket 3 is equipped with a flushing liquid delivery assembly 7, and the flushing liquid delivery assembly 7 is connected to the flushing liquid port of the flushing and drainage device 6 through a flushing pipeline 71. The negative pressure drainage port of the flushing and drainage device 6 is connected to the drainage device 4, and the drainage device 4 is connected to the negative pressure device 5. The negative pressure device 5 and the drainage device 4 are respectively installed on the mobile base 1. A peristaltic pump 9 electrically connected to the controller 2 is provided on the outside, and the flushing pipeline 71 passes through the peristaltic pump 9.

[0026] The design of the medical irrigation and suction integrated device of this embodiment is relatively simple. All the core components are integrated and installed on the mobile base 1 and the upper end of the column 11. The electronic weighing device 8 is used to weigh the entire system except the mobile base 1 in real time. The electronic weighing device 8 records the weight information of the entire system before and after the irrigation and drainage operation in real time to obtain the difference (especially the weight after the operation is much greater than the weight before the operation). If the difference is greater than the set safety value, it means that the patient's body fluid loss during the operation is large, so the doctor needs to perform relevant treatment on the patient (such as replenishing body fluids, or other emergency treatment) in order to eliminate the patient's physical discomfort in time. The entire system has a reasonable structural design and is easy to operate. It can realize the integration of irrigation and suction functions, as well as the free switching of separate irrigation, separate suction and simultaneous irrigation and suction functions. The patient's body fluid loss can be monitored in real time during the operation, and a fluid replenishment reference can be provided to medical staff in real time.

[0027] As a preferred embodiment, Figure 2 As shown, the drainage device 4 includes a storage box 41 and a plurality of foldable drainers 42. The storage box 41 is provided with a accommodating cavity with two sides passing through it, and the upper end of the accommodating cavity is provided with an opening. The accommodating cavity is detachably provided with a drain placement groove 43 which can be taken out or put in from any side thereof. The bottom of the drain placement groove 43 is provided with an elastic support component 44, and the upper end of the elastic support component 44 is provided with a plurality of foldable drainers 42 which are stacked up and down and are in a folded state. The uppermost foldable drainer 42 can be pulled out and stretched upward from the notch at the upper end of the drain placement groove 43. The upper ends of the foldable drainers 42 are respectively provided with a waste liquid interface (denoted by c in the figure) and a negative pressure interface (denoted by d in the figure) connected to the interior thereof, and the waste liquid interface is detachably connected with a drainage pipeline 45 connected to the negative pressure drainage port, and the negative pressure interface is detachably connected with a negative pressure pipeline 46 connected to the negative pressure device 5.

[0028] In the above embodiment, before the operation, the drain placement slot 43 equipped with multiple foldable drains 42 (multiple foldable drains 42 are stacked up and compressed and placed in the drain placement slot 43) is pre-installed in the accommodating cavity of the storage box 41 (when loading, it can be pushed in from the side end, and when taking out, it is also taken out from the side end), then, the uppermost foldable drain 42 in the drain placement slot 43 is pulled out from the upper end notch of the drain placement slot 43 and unfolded, and the unfolded state is maintained, and the negative pressure pipeline 46 and the drainage pipeline 45 are connected to the waste liquid of the uppermost foldable drain 42. The port and the negative pressure interface are connected, and then the negative pressure pipeline 46 and the drainage pipeline 45 are respectively connected to the negative pressure equipment 5 and the negative pressure drainage port of the flushing and drainage device 6, and the flushing liquid delivery component 7 is connected to the flushing liquid port of the above-mentioned flushing and drainage device 6 through the flushing pipeline 71, and the flushing pipeline 71 is inserted into and passed through the peristaltic pump 9. The peristaltic pump 9 can then deliver the flushing liquid in the flushing liquid delivery component 7 to the flushing and drainage device 6 through the flushing pipeline 71, and then the flushing and drainage device 6 can be switched to the two states of positive pressure flushing or negative pressure drainage to achieve the flushing or drainage operation. When the top foldable drainer 42 is loaded with an appropriate amount of waste liquid and needs to be removed, the negative pressure pipeline 46 and the drainage pipeline 45 are removed, and the top foldable drainer 42 is taken out. Under the elastic force of the elastic support component 44, the foldable drainer 42 is pushed upward, and the top foldable drainer 42 is continued to be unfolded and held from the notch of the drainer placement slot 43, and then the subsequent flushing or drainage can be carried out according to the above method. The entire device can store the foldable drainers 42 in batches, and the replacement is relatively convenient and fast.

[0029] As a preferred embodiment, the two ends of the bottom of the above-mentioned accommodating cavity are respectively provided with limit grooves protruding outward, the two ends of the upper end opening of the above-mentioned accommodating cavity are respectively provided with first limit blocks inward, and the two ends of the lower end of the above-mentioned diverter placement groove 43 are respectively provided with second limit blocks adapted to the above-mentioned limit grooves, and the above-mentioned second limit blocks are respectively embedded in the above-mentioned limit grooves.

[0030] In the above embodiment, after the drainage device placement slot 43 is loaded into the accommodating cavity, the upper part is abutted against the first limit block at the upper end of the accommodating cavity, and the second limit blocks at both ends of the lower part of the drainage device placement slot 43 are respectively embedded in the limit slots at both ends of the lower part of the accommodating cavity, so that the drainage device placement slot 43 is restricted in the vertical direction and can only be pulled out or put in from the side, so as to avoid vertical displacement during the negative pressure drainage process.

[0031] As a preferred embodiment, the inner cavity of the drain placement groove 43 passes through the side walls on both sides thereof, and the elastic support assembly 44 includes a plurality of groups of first springs 441 and a support plate 442 connected to the upper end of the first springs 441 .

[0032] In the above embodiment, both sides of the drain placement slot 43 are also connected, and when the top foldable drain 42 needs to be removed, it can be pulled out from the side of the drain placement slot 43. At the same time, when the foldable drain 42 is loaded into the drain placement slot 43, the first spring 441 is always in a compressed state, and therefore, an upward reaction force is always provided, so that the multiple foldable drains 42 always tend to move upward, ensuring that after the top foldable drain 42 is taken out, the adjacent foldable drains 42 below can quickly move upward.

[0033] As a preferred embodiment, the foldable drain device 42 includes a bottom cover 421, a top cover 422 and a bag body 423. The top cover 422 is arranged above the bottom cover 421. The bag body 423 is connected between the bottom cover 421 and the top cover 422. The bag body 423 is provided with a second spring 424 respectively connected to the bottom cover 421 and the top cover 422. The top cover 422 is provided with the waste liquid interface and the negative pressure interface.

[0034] In the above-mentioned embodiment, among the multiple foldable drainers 42, the bottom cover 421 of the upper foldable drainer 42 is pressed on the upper end of the adjacent foldable drainer 42 below (it can be directly pressed on the waste liquid interface and the negative pressure interface, or a depression can be provided in the middle of the top cover 422, and the waste liquid interface and the negative pressure interface can be set in the depression of the top cover 422, ensuring that the upper end of the top cover 422 is a flat surface), and the bag body 423 is a flexible cylindrical bag body with multiple folds. When stretched, the uppermost The top cover 422 of the layer passes through the notch of the drain placement groove 43, and the edge of the bottom cover 421 is restricted to the inner side of the notch of the drain placement groove 43. Then, the second spring 424 is released, and the elastic force of the second spring 424 can keep a specific distance between the top cover 422 and the bottom cover 421, so that the bag body 423 is stretched and expanded. When the gas in the bag body 423 is sucked by negative pressure, the bag body 423 will not shrink significantly, ensuring that drainage can be achieved inside.

[0035] It should be noted that the second spring 424 can be replaced by a plurality of struts, and positioning holes adapted to the struts are respectively provided at the upper end of the bottom cover 421 and the lower end of the top cover 422. The struts are vertically arranged, and the upper and lower ends are respectively inserted into the corresponding positioning holes, so as to maintain the distance between the bottom cover 421 and the top cover 422, thereby achieving the purpose of stretching and expanding the bag body 423, ensuring that the bag body 423 will not be significantly shrunk under the action of negative pressure suction, and can smoothly achieve drainage (collection of waste liquid).

[0036] As a preferred embodiment, a first interface 451 is provided at one end of the drainage pipeline 45, a first duckbill one-way valve 452 is provided in the port of the first interface 451, the waste liquid interface of the uppermost foldable drain device 42 can be detachably inserted into the first duckbill one-way valve 452, a second interface 461 is provided at one end of the negative pressure pipeline 46, a second duckbill one-way valve 462 is provided in the port of the second interface 461, and the negative pressure interface of the uppermost foldable drain device 42 can be detachably inserted into the second duckbill one-way valve 462.

[0037] In the above implementation scheme, the design of the first duckbill one-way valve 452 is relatively reasonable. After the waste liquid interface is pulled out from the first interface 451, the first duckbill one-way valve 452 is automatically closed to avoid leakage. Similarly, after the negative pressure interface is pulled out from the second interface 461, the second duckbill one-way valve 462 is also automatically closed to avoid leakage, thereby facilitating the removal and replacement of the foldable drain 42 filled with waste liquid.

[0038] As a preferred embodiment, the flushing liquid delivery assembly 7 includes a plurality of flushing liquid bags 72, which are hung on the upper end of the rack 3, and the bag openings of the flushing liquid bags 72 are respectively connected with infusion tubes 73, and the ends of the infusion tubes 73 away from the flushing liquid bags 72 are respectively connected to the flushing pipelines 71.

[0039] In the above embodiment, multiple flushing liquid bags 72 are respectively connected to an infusion tube 73 (wherein, the flushing liquid bag 72 is similar to a conventional infusion bag in a hospital, and a hard puncture portion is provided at the end of the infusion tube 73, which can be passed through the rubber plug in the bag opening of the flushing liquid bag 72), and the flushing liquid in the flushing liquid bag 72 flows into the flushing line 71 through the infusion tube 73, and then is effectively transported to the flushing and drainage device 6 under the action of the peristaltic pump 9. Among them, you can choose to connect only one flushing liquid bag 72 for flushing first, and connect another flushing liquid bag 72 after the flushing liquid in one flushing liquid bag 72 is used up, or multiple flushing liquid bags 72 are supplied with liquid at the same time.

[0040] In this embodiment, the parameters of the peristaltic pump 9 can be effectively adjusted by the controller 2 , and the controller 2 can adopt a conventional industrial computer, or a control product with a display configured by an adapted model available on the market.

[0041] As a preferred embodiment, Figure 3As shown, the flushing and drainage device 6 includes a flushing and suction tube cavity 61, a flushing and suction extension tube 62, a first branch tube 63 and a second branch tube 64. One end of the flushing and suction extension tube 62 is connected and communicated with one end of the flushing and suction tube cavity 61. The middle part of the flushing and suction tube cavity 61 is provided with a main cavity 65 vertically communicated therewith. One end of the first branch tube 63 and the second branch tube 64 are respectively connected and communicated with the side ends of the main cavity 65. The other end tube openings of the first branch tube 63 and the second branch tube 64 are respectively sealed with elastically retractable first pressing heads 66 and second pressing heads 67. The first pressing head 66 is provided with a hollow first column 661 extending into the first branch tube 63, and the second pressing head 67 is provided with a hollow second column 671 extending into the second branch tube 64. A first inlet (indicated by a in the figure) is opened at the side end of the branch pipe 63, a second inlet (indicated by b in the figure) is opened at the side end of the second branch pipe 64, a first hole adapted to the first inlet is opened at the side wall of the first tube column 661, and a second hole adapted to the second inlet is opened at the side wall of the second tube column 671. The first pressing head 66 can be elastically pressed to the first hole to connect with the first inlet under the action of external force, or move back to its position after the external force is removed so that the first tube column 661 blocks the first inlet. The second pressing head 67 can be elastically pressed to the second hole to connect with the second inlet under the action of external force, or move back to its position after the external force is removed so that the second tube column 671 blocks the second inlet. The first inlet constitutes the flushing liquid port, and the second inlet constitutes the negative pressure drainage port.

[0042] In the above embodiment, when not in use, the first hole and the second hole on the first tube column 661 and the second tube column 671 are respectively misaligned with the first inlet on the first branch tube 63 and the second inlet on the second branch tube 64. That is, when not in use, the first tube column 661 blocks the first inlet and the second tube column 671 blocks the second inlet. When positive pressure flushing is required, the first pressing head 66 is pressed, and the first tube column 661 moves toward the end of the first branch tube 63 connected to the main cavity 65, and the first hole is connected to the first inlet, so that the flushing liquid can enter the first branch tube 63 through the first inlet and the first hole, and then enter the flushing and suction extension tube 62 through the main cavity 65 and the flushing and suction cavity 61, and then enter the flushing and suction extension tube 62 from the flushing and suction cavity 61. The port of the extension tube 62 is ejected for flushing. When negative pressure drainage is performed, the first pressing head 66 is released, the first tube column 661 returns to its position, the first inlet is blocked again, and the second pressing head 67 is pressed. The second tube column 671 is driven to move toward the end of the first branch tube 63 connected to the main cavity 65, and the second hole is connected to the second inlet, and negative pressure is generated at the second inlet. Since the second inlet, the second hole, the main cavity 65, the flushing and suction tube cavity 61 and the flushing and suction extension tube 62 are connected, negative pressure is generated at the port of the flushing and suction extension tube 62, and the waste liquid after flushing will enter the drainage device 4 through the above-mentioned pipeline, specifically, into the bag body 423 of the foldable drain 42 of the top layer of the drainage device 4. The entire flushing and drainage device 6 is very cleverly designed, and the operation is very simple and convenient, and only two pressing heads need to be pressed.

[0043] More specifically, a cylindrical tube body is respectively provided at one end of the first branch tube 63 and the second branch tube 64 away from the main cavity 65, in which a first pressing head 66 or a second pressing head 67 is respectively installed in a sealing and sliding manner, and an elastic member is connected between the first pressing head 66 and the second pressing head 67 and one end of the tube body. The first pressing head 66 or the second pressing head 67 is respectively coaxially connected to the first tube column 661 and the second tube column 671 extending into the first branch tube 63 and the second branch tube 64. The first pressing head 66 or the second pressing head 67 respectively overcomes the elastic force of the elastic member and presses, so that the first tube column 661 and the second tube column 671 respectively move to their respective first holes and second holes to be connected with the first inlet and the second inlet pair holes.

[0044] As a preferred embodiment, the controller 2 is externally provided with a constant temperature heating device 10 connected thereto, and the flushing pipeline 71 passes through the constant temperature heating device 10 .

[0045] In the above embodiment, the constant temperature heating device 10 can heat the flushing liquid flowing through the flushing pipeline 71, keep the flushing liquid at a temperature suitable for the patient during flushing, improve the comfort of flushing, and reduce adverse stimulation of flushing.

[0046] In this embodiment, the constant temperature heating device 10 belongs to the prior art. A channel for passing the pipeline is provided in the shell, and a heating cavity is formed between the outside of the channel and the shell. An electric heater (electric heating wire or electric heating tube) is provided in the heating cavity, and a temperature sensor is provided on the inner wall of the channel. The electric heater and the temperature sensor are respectively connected to the controller 2.

[0047] In this embodiment, the column 11 is a liftable column. Specifically, the column 11 can be made of two or more hollow tubes that are inserted into each other. At the insertion position, a tightening bolt is vertically screwed on the side wall of the port of the outer hollow tube. The relative movement or fixation of the two hollow tubes is achieved by tightening the bolt until it abuts against or separates from the side wall of the inner sleeve hollow tube, and finally the telescopic height adjustment of the column 11 is achieved. The position of the controller can be adjusted according to the operating habits or height of the medical staff, making it more comfortable to use.
