Description
Technical Field
[0001] This utility model relates to the technical field of a supporting device for a press-type negative pressure drainage device, specifically to a placement basket for a press-type negative pressure drainage device. Background Technology
[0002] Gastrointestinal decompression is a common technique in general surgery, and negative pressure drainage devices are typically used to observe the color, consistency, and quantity of the drainage fluid. Clinically, negative pressure drainage devices can also be used to suction out sputum, contaminated blood, and secretions from patients.
[0003] Currently, a type of press-type negative pressure drainage device is frequently used in clinical practice. It is not only simple in structure and low in cost, but also relatively convenient to use. This press-type negative pressure drainage device consists of a bottle with corrugated sidewalls. On opposite sides of the top center of the bottle, there is a drainage connection tube and a connecting hole. In use, simply connect the corresponding drainage connection tube to the external end of the drainage tube. Pressing the negative pressure drainage device will cause it to return to its initial state under the restoring force, thus creating negative pressure within the device to allow drainage from the tube.
[0004] However, in actual use, it was found that due to its corrugated sidewall structure, the sidewall lacks adequate rigid support. This results in uneven force distribution when pressing the top of the negative pressure drainage device, causing the top of the device to move downwards more on the side with greater force, while the other side moves downwards less. This leads to the top of the negative pressure drainage device tilting, and even bending of the sidewall, potentially causing the device to slip out of the hand during pressing. Furthermore, this makes pressing the negative pressure drainage device cumbersome, requiring both hands to apply relatively even force to both opposite sides simultaneously. Utility Model Content
[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a placement basket for a press-type negative pressure drainage device. This basket not only facilitates the placement of the negative pressure drainage device, but also ensures that the top of the negative pressure drainage device is evenly stressed when pressed through the structure of the pressure plate. In addition, the limiting rod prevents the negative pressure drainage device from tilting when pressed, thus avoiding affecting its use.
[0006] The technical solution adopted by this utility model is:
[0007] The placement basket for the press-type negative pressure drainage device includes a circular base plate. Multiple limiting rods are evenly fixed along the top edge of the base plate. The ring formed by the limiting rods is coaxial with the base plate. Multiple sets of horizontally arranged arc-shaped rods are evenly fixed at intervals from bottom to top on the outer side of the limiting rods. These arc-shaped rods fix multiple adjacent limiting rods. Each set of arc-shaped rods includes two arc-shaped rods A and B. A gap A is provided between one end of each of the two arc-shaped rods A. An arc-shaped rod B is provided between the ends. A gap B is provided between the end of the arc-shaped rod B and the end of the corresponding arc-shaped rod A. The arc-shaped rod A is axially symmetrical about the perpendicular bisector of the arc-shaped rod B. Above the base plate, within the area enclosed by the limiting upright, a pressure plate is also provided that moves up and down along the limiting upright. The center of the pressure plate is coaxially provided with a central hole. The inner diameter of the central hole is greater than or equal to the diameter of the protruding cover at the top center of the negative pressure drain. A limiting pin is also provided on one side of the top of the pressure plate.
[0008] A further improvement of this utility model is that the edge of the pressure plate is provided with guide sleeves that match the limiting rod at positions corresponding to gaps A and B, and the inner diameter of the guide sleeves matches the diameter of the limiting rod.
[0009] A further improvement of this utility model is that the pressure plate is fixed to the guide sleeve by a connecting plate, and the connecting plate is provided with a through hole corresponding to the guide sleeve and matching the inner diameter of the guide sleeve.
[0010] A further improvement of this utility model is that at least one limiting rod is provided between the gaps A and between the gaps B, and there are two guide sleeves corresponding to the gaps A and B, respectively. The guide sleeves are connected to the two outermost limiting rods in the gap A or the two outermost limiting rods in the gap B.
[0011] A further improvement of this utility model is that the limiting pin includes a pin guide sleeve fixed to the top plate of the pressure plate. The pin guide sleeve contains a pin that can reciprocate along the pin guide sleeve. When the pin moves outward to its maximum stroke, the distance between the end of the pin away from the axis of the base plate and the axis of the base plate is greater than the distance between the arc rod and the axis of the base plate. When the pin moves inward to its maximum stroke, the distance between the end of the pin away from the axis of the base plate and the axis of the base plate is less than the distance between the arc rod and the axis of the base plate.
[0012] A further improvement of this utility model is that the pin guide sleeve is provided in at least one set, and each set of pin guide sleeves includes multiple pin guide sleeves arranged in parallel. The end of the pin in the same set of pin guide sleeves facing the center of the base plate extends out of the pin guide sleeve and is fixedly connected by an operating linkage.
[0013] A further improvement of this utility model is that the bottom of the operating link is provided with a connecting rod corresponding to the end of the pin to which it is connected, and the operating link is fixed to the pin through the connecting rod.
[0014] A further improvement of this utility model is that, when there is one set of pin guide sleeves, the axis of the set of pin guide sleeves points to the arc-shaped rod B, and all the pin guide sleeves in the set are within the range of the arc-shaped rod B; when there are two sets of pin guide sleeves, the two sets of pin guide sleeves are respectively located on two opposite sides of the axis of the base plate, and the axis of each set of pin guide sleeves points to the arc-shaped rod A on its respective side, and the pin guide sleeves of the corresponding set are all within the range of the arc-shaped rod A on its respective side; when there are three sets of pin guide sleeves, the axis of one set of pin guide sleeves points to the arc-shaped rod B, and all the pin guide sleeves in the set are within the range of the arc-shaped rod B, while the axis of the other two sets of pin guide sleeves points to arc-shaped rod A on different sides, and the pin guide sleeves of the corresponding sets are all within the range of the arc-shaped rod A on their respective sides.
[0015] A further improvement of this utility model is that the top surface height of the protruding cover at the highest position, which moves upward under the action of the negative pressure drainer's own restoring force, is lower than the top height of the limiting upright.
[0016] The beneficial effects of this utility model are as follows:
[0017] First, the placement basket of the press-type negative pressure drainage device of this utility model not only facilitates the placement of the negative pressure drainage device, but also ensures that the top of the negative pressure drainage device is evenly stressed when pressed through the structure of the pressure plate. In addition, the limiting rod prevents the negative pressure drainage device from tilting when pressed, thus affecting its use.
[0018] Secondly, the placement basket of the press-type negative pressure drainage device of this utility model is connected to the limiting rod through the guide sleeve set on the pressure plate, thereby further ensuring the stable and smooth up and down movement of the pressure plate.

[0020] Fourth, the placement basket of the press-type negative pressure drainage device of this utility model, through the pin provided on the pressure plate, can be limited by the pin extending out and interlocking with the arc-shaped rod, so that the negative pressure drainage device can return to the designated state under the action of restoring force, so that the user can perform other operations.
[0021] Fifth, the placement basket of the press-type negative pressure drainage device of this utility model, connected to the operating linkage by the pin, facilitates the simultaneous operation of the pins of the same set of pin guide sleeves, thereby improving operating efficiency.

[0027] Combination Figures 1-5 It is known that the placement basket of the press-type negative pressure drainage device includes a circular base plate 1. Multiple limiting rods 2 are evenly fixed along the top edge of the base plate 1. The ring formed by the limiting rods 2 is coaxial with the base plate 1. Multiple sets of horizontally arranged arc-shaped rods are fixed at equal intervals from bottom to top on the outer side of the limiting rods 2. The arc-shaped rods fix multiple adjacent limiting rods 2. Each set of arc-shaped rods includes two arc-shaped rods A3 and B4. A gap A5 is provided between one end of the two arc-shaped rods A3, and the other end of the two arc-shaped rods A4... An arc-shaped rod B4 is provided, and a gap B6 is provided between the end of the arc-shaped rod B4 and the end of the corresponding arc-shaped rod A3. The arc-shaped rod A3 is axially symmetrical about the perpendicular bisector of the arc-shaped rod B4. Above the base plate 1, within the area enclosed by the limiting rod 2, a pressure plate 7 is also provided that moves up and down along the limiting rod 2. The center of the pressure plate 7 is coaxially provided with a central hole 9. The inner diameter of the central hole 9 is greater than or equal to the diameter of the protruding cover 15 at the top center of the negative pressure drain 14. A limiting pin is also provided on one side of the top of the pressure plate 7.
[0028] The edge of the pressure plate 7 is provided with guide sleeves 8 that match the limiting rod 2 at the positions corresponding to gaps A5 and B6. The inner diameter of the guide sleeve 8 matches the diameter of the limiting rod 2.
[0029] The pressure plate 7 is fixed to the guide sleeve 8 by the connecting plate 10, and the connecting plate 10 is provided with a through hole that matches the inner diameter of the guide sleeve 8.
[0030] At least two limiting rods 2 are provided between gaps A5 and B6 respectively. There are two guide sleeves 8 corresponding to gaps A5 and B6. The guide sleeves 8 are connected to the two outermost limiting rods 2 in gap A5 or the two outermost limiting rods 2 in gap B6 respectively.
[0031] The limiting pin includes a pin guide sleeve 12 fixed to the top plate of the pressure plate 7. The pin guide sleeve 12 is provided with a pin 11 that can reciprocate along the pin guide sleeve 12. When the pin 11 moves outward to the maximum stroke, the distance between the end of the pin 1 away from the axis of the base plate 1 and the axis of the base plate 1 is greater than the distance between the arc rod and the axis of the base plate 1. When the pin 11 moves inward to the maximum stroke, the distance between the end of the pin 1 away from the axis of the base plate 1 and the axis of the base plate 1 is less than the distance between the arc rod and the axis of the base plate 1.
[0032] At least one set of pin guide sleeves 12 is provided. Each set of pin guide sleeves 12 includes multiple pin guide sleeves 12 arranged in parallel. The end of the pin 11 in the same set of pin guide sleeves 12 facing the axis of the base plate 1 extends out of the pin guide sleeve 12 and is fixedly connected by the operating link 13.
[0033] The bottom of the operating link 13 is provided with a connecting rod corresponding to the end of the pin 11 to which it is connected, and the operating link 13 is fixed to the pin 11 by the connecting rod.
[0034] When the pin guide sleeve 12 is in one group, the axis of the group of pin guide sleeves 12 points to the arc-shaped rod B4, and the pin guide sleeves 12 in the group are all within the range of the arc-shaped rod B4; when there are two groups of pin guide sleeves 12, the two groups of pin guide sleeves 12 are respectively located on two opposite sides of the axis of the base plate 1, and the axis of each group of pin guide sleeves 12 points to the arc-shaped rod A3 on its own side, and the pin guide sleeves 12 in the corresponding group are all within the range of the arc-shaped rod A3 on its own side; when there are three groups of pin guide sleeves 12, the axis of one group of pin guide sleeves 12 points to the arc-shaped rod B4, and the pin guide sleeves 12 in the group are all within the range of the arc-shaped rod B4, while the axis of the other two groups of pin guide sleeves 12 points to the arc-shaped rod A3 on different sides, and the pin guide sleeves 12 in the corresponding group are all within the range of the arc-shaped rod A3 on its own side.
[0035] The top surface of the protruding cover 15, which moves upward to its highest position under the action of the self-restoring force of the negative pressure drain 14, is lower than the top height of the limiting rod 2.
[0036] When using this application, first separate the pressure plate 7 from the top of the limiting rod 2 upwards from the placement basket. Then, place the negative pressure drain 14 into the placement basket, ensuring that the bottom of the negative pressure drain 14 contacts the bottom plate 1 of the placement basket. At this time, the side of the negative pressure drain 14 is limited by the limiting rod 12. Next, place the guide sleeve 8 of the pressure plate 7 onto the limiting rod 12 at the gaps A5 and B6, and lower it into the placement basket along the limiting rod 2, so that the bottom of the pressure plate 7 contacts the top of the negative pressure drain 14, and the protruding cover 15 of the negative pressure drain 14 protrudes upwards through the middle of the pressure plate 7. Heart hole 9; Next, close the regulating valve of the drainage connection pipe 16 at the top of the protruding cover 15 of the negative pressure drainage device 14, and open the cover of the connecting hole 17. Then, press down the pressure plate 7 to move the top of the negative pressure drainage device 14 downward. During the pressing process, the air in the negative pressure drainage device 14 is discharged outward through the connecting hole 17. When the pressure plate 7 is pressed down to the maximum stroke, the hand pressure plate of the negative pressure drainage device 14 is pressed down to the maximum contraction state. At this time, close the cover of the connecting hole 17. Then, through the operating linkage 13, extend each pin 11 outward to the corresponding pin guide sleeve 12. At this time, each pin 1 1. Both are located between two adjacent arc-shaped rods A3 or B4; then connect the end of the drainage connection tube 16 to the external end of the drainage tube inserted into the patient's body; then open the regulating valve of the drainage connection tube 16 and adjust the opening degree. At this time, the pressure plate 7 moves upward under the restoring force of the negative pressure drainage device 14. During this process, a negative pressure will be formed in the negative pressure drainage device 14, so that the drainage tube can play a drainage role for the patient, and the drainage material will directly enter the negative pressure drainage device 14; when the pin 11 of the pressure plate 7 moves upward to be limited by the upper arc-shaped rod A3 or arc-shaped rod B4. At this time, the restoring force of the negative pressure drainage device 14 is insufficient to make the negative pressure drainage device 14 continue to move upward, and the negative pressure in the negative pressure drainage device 14 can no longer be generated. Through the above process, the drainage effect of the drainage tube can be observed. Then, the regulating valve is adjusted. After the regulating valve is adjusted, the connecting rod 13 can be used to retract each pin 11 inward until it does not contact the arc rod A3 and arc rod B4. This allows the top of the negative pressure drainage device 14 to move upward again under its own restoring force, thereby generating negative pressure in the negative pressure drainage device 14 again to achieve the drainage effect. Moreover, the drainage efficiency meets the requirements.
[0037] Because gas is also discharged during the outward drainage process of the drainage tube in addition to drainage fluid or other drainage materials, when the top of the negative pressure drainage device 14 moves upward to the maximum stroke under its own restoring force, there will still be a certain gap between the drainage fluid surface inside the negative pressure drainage device 14 and the top of the negative pressure drainage device 14. In order to improve the utilization rate of the negative pressure drainage device 14, the negative pressure drainage device 14 will generally be pressed down again until the top of the negative pressure drainage device 14 is located at the drainage fluid surface position, so as to perform negative pressure drainage again. During operation, the regulating valve of the drainage connection tube 16 needs to be closed again, and the cover of the connecting hole 17 needs to be opened. Then, the pressure plate 7 is pressed down to move the top of the negative pressure drainage device 14 downward. During the downward pressing process, the air in the negative pressure drainage device 14 is discharged outward through the connecting hole 17. When the pressure plate 7 is pressed down until the top of the negative pressure drainage device 14 is at the liquid level of the drainage fluid, the cover of the connecting hole 17 is closed. Then, the regulating valve of the drainage connection tube 16 is opened again and adjusted to the previous state to continue drainage. The above operation is repeated until the top of the negative pressure drainage device 14 moves upward again to the maximum stroke position, and the liquid level of the drainage fluid in the negative pressure drainage device 14 is greater than or equal to four-fifths of the height of the negative pressure drainage device 14 when it moves upward to the maximum stroke position. At this time, it is necessary to replace the negative pressure drainage device 14 to drain the drainage fluid or directly replace it with a new negative pressure drainage device 14.
[0038] To drain the drainage fluid from the negative pressure drainer 14, simply close the regulating valve of the drainage connection pipe 16, open the cover of the connecting hole 17, align the connecting hole 17 with the waste liquid pool, and then press the negative pressure drainer 14 to drain the drainage fluid from the negative pressure drainer 14.
