Description

Technical Field

[0001] This invention relates to the field of postoperative drainage technology, and more particularly to a postoperative drainage device. Background Technology

[0002] After hepatobiliary surgery, drainage devices are needed for drainage. For example, after hepatobiliary stone surgery, they are used to drain bile, prevent bile leakage, and support the bile duct to prevent stricture. After liver resection or cholecystectomy, they are used to drain ascites, bleeding, or foci of infection.

[0003] Chinese Patent [Publication No.: CN223380864U] discloses a novel drainage device for hepatobiliary surgery, including a collection bag connected to a drainage tube via a connecting tube one and a connecting cap one, a collection bag connected to a negative pressure suction ball via a connecting tube two and a connecting cap two, and a partition strip one and a partition strip two provided on the inner side of the collection bag, which effectively prevents accumulated fluid from entering the negative pressure suction ball.

[0004] Although the device can prevent liquid from entering the negative pressure suction ball to some extent by setting up partitions, the presence of partitions reduces the liquid storage capacity of the drainage container, and the liquid located between the partitions is not easy to drain when discharging liquid. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a postoperative drainage device that solves the problems in the prior art where the presence of the septum reduces the amount of fluid stored in the drainage container, and the fluid located between the septum is not easy to drain when draining accumulated fluid.

[0006] The present invention solves the above-mentioned technical problems through the following technical means:

[0007] A postoperative drainage device includes a drainage container, a drainage tube, and a negative pressure suction ball. The drainage container is provided with a liquid inlet connector, a liquid outlet connector, and a negative pressure connector. The liquid inlet connector is used to connect to the drainage tube, the liquid outlet connector is used to drain the accumulated liquid in the drainage container, and the negative pressure connector is used to connect to the negative pressure suction ball or to connect the drainage container to the outside.

[0008] It also includes a sealing assembly, the sealing assembly comprising:

[0009] A connecting sleeve is sealed and installed on a negative pressure connector, and the connecting sleeve is in communication with the negative pressure connector;

[0010] A rod is fixedly connected to the connecting sleeve along the length of the connecting sleeve, and the end of the rod extends into the drainage container;

[0011] The counterweight is slidably sleeved on the rod.

[0012] The sealing head is installed on top of the counterweight;

[0013] A tension spring, one end of which is fixedly connected to a connecting sleeve, and the other end of which is fixedly connected to a counterweight;

[0014] A sealing ring is fixedly disposed inside the connecting sleeve and is used to cooperate with the sealing head to seal the connecting sleeve;

[0015] When the sum of the component force of the counterweight along the length of the rod and the frictional force between the counterweight and the rod is less than the tension force of the tension spring on the counterweight, the tension spring pulls the counterweight toward the sealing ring and causes the sealing head to come into contact with the sealing ring.

[0016] By setting the above structure, when the drainage container is horizontal or nearly horizontal, the tension spring pulls the counterweight block to move closer to the sealing ring, and drives the sealing head to abut against the sealing ring, so that the connecting sleeve automatically seals, effectively preventing liquid from entering the negative pressure suction ball.

[0017] Furthermore, the counterweight has a through hole, and sliding parts are installed at both the upper and lower ends of the counterweight. The counterweight is slidably connected to the rod through the sliding parts, which are used to reduce the friction between the counterweight and the rod.

[0018] By setting the above structure, the friction between the counterweight and the rod is reduced, making it easier for the tension spring to pull the counterweight along the rod.

[0019] Furthermore, an annular airbag is fixedly installed on the counterweight block. The annular airbag is located between the counterweight block and the sealing head. When there is too much liquid inside the drainage container, the annular airbag is floated by the liquid to provide buoyancy, which assists the tension spring in pulling the counterweight block upward so that the sealing head abuts against the sealing ring.

[0020] By setting up the above structure, when there is too much liquid, the annular airbag is floated by the liquid to provide buoyancy, and then cooperates with the tension spring to make the sealing head abut against the sealing ring, automatically sealing the connecting sleeve.

[0021] Furthermore, the top of the connecting sleeve is provided with an installation cavity, in which a battery, a buzzer, and a warning light are fixedly installed. The sealing head is provided with an energizing ring, and the connecting sleeve is provided with a first electrode plate and a second electrode plate. Both the first and second electrode plates are electrically connected to the battery. When the sealing head pushes the energizing ring upward and makes contact with the first and second electrode plates, the battery supplies power to the buzzer and the warning light, and the buzzer and the warning light begin to work.

[0022] By setting up the above structure, when the sealing head comes into contact with the sealing ring and seals, the buzzer and warning light will work to remind the patient to adjust the position of the drainage container or drain the accumulated fluid in the drainage container.

[0023] Furthermore, a protective component is provided inside the drainage container at the position corresponding to the negative pressure connector. The protective component forms a protective area inside the drainage container, and the bottom of the rod is located within the protective area. The protective area is used to prevent the accumulated liquid flowing in from the inlet connector from directly splashing onto the sealing component.

[0024] By setting up the above structure, the accumulated liquid flowing in from the inlet joint is prevented from splashing directly onto the sealing component, thus avoiding the accumulation liquid from entering the negative pressure suction ball.

[0025] Furthermore, the protective component includes a first baffle and a second baffle. The first baffle is located between the liquid inlet connector and the negative pressure connector, and the second baffle is located below the sealing assembly. The first baffle is used to block the liquid splashed in the direction of the liquid inlet connector, and the second baffle is used to block the liquid splashed in the bottom of the drainage container.

[0026] Furthermore, the second stop bar is inclined downward from the end furthest from the first stop bar to the end closest to the first stop bar.

[0027] The above structure facilitates the drainage of accumulated liquid within the protected area.

[0028] Furthermore, the connecting sleeve includes an upper sleeve body and a lower sleeve body, the upper sleeve body and the lower sleeve body are sealed and fixedly connected, and the mounting cavity is formed at the connection between the upper sleeve body and the lower sleeve body.

[0029] The above structure facilitates battery replacement.

[0030] Furthermore, an outer sleeve is fixedly provided at the connection end of the connecting sleeve and the negative pressure connector, and the outer sleeve is threadedly connected to the negative pressure connector.

[0031] Furthermore, the end of the sealing head near the sealing ring is spherical.

[0032] The beneficial effects of this invention are:

[0033] 1. By setting a sealing component, when the drainage container is horizontal or nearly horizontal, the tension spring pulls the counterweight block to move closer to the sealing ring, and drives the sealing head to abut against the sealing ring, so that the connecting sleeve automatically seals, effectively preventing the accumulated liquid from entering the negative pressure suction ball, effectively protecting the storage space inside the drainage container, and avoiding the problem of the accumulated liquid being difficult to drain in the prior art.

[0034] 2. By setting up a sliding component, the present invention reduces the friction between the counterweight and the rod, making it easier for the tension spring to pull the counterweight along the rod.

[0035] 3. The present invention uses an annular airbag. When there is too much liquid, the annular airbag is floated by the liquid and provides buoyancy. In conjunction with the tension spring, the sealing head abuts against the sealing ring and automatically seals the connecting sleeve.

[0036] 4. This invention incorporates a buzzer and a warning light. When the sealing head comes into contact with the sealing ring and seals, the buzzer and warning light activate to remind the patient to adjust the position of the drainage container or drain the accumulated fluid from the drainage container.

[0037] 5. The present invention makes it easier to drain the accumulated liquid in the protected area by tilting the second baffle. Attached Figure Description

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] like Figures 1-4 As shown, a postoperative drainage device according to this embodiment includes a drainage container 1, a drainage tube 2, and a negative pressure suction ball 3. The drainage container 1 is provided with a liquid inlet connector 11, a liquid outlet connector 12, and a negative pressure connector 13. The liquid inlet connector 11 is used to connect to the drainage tube 2, the liquid outlet connector 12 is used to drain the accumulated liquid in the drainage container 1, and the negative pressure connector 13 is used to connect to the negative pressure suction ball 3 or to connect the drainage container 1 to the outside. The liquid inlet connector 11, the drainage tube 2, and the negative pressure suction ball 3 have been fully disclosed in the prior art, so the specific working principle will not be described in detail.

[0053] It also includes a sealing component 4, which includes:

[0054] A connecting sleeve 41 is sealed and installed on the negative pressure connector 13, and the connecting sleeve 41 communicates with the negative pressure connector 13. In this embodiment, an outer sleeve 411 is fixedly provided at the connection end between the connecting sleeve 41 and the negative pressure connector 13, and the outer sleeve 411 is threadedly connected to the negative pressure connector 13. In some other embodiments, a sealed sleeve connection can also be used to achieve the connection between the connecting sleeve 41 and the negative pressure connector 13.

[0055] The rod 42 is fixedly connected to the connecting sleeve 41 along its length, with its end extending into the drainage container 1. In this embodiment, a connecting seat is provided inside the connecting sleeve 41, and the connecting seat has several air holes. This allows gas to flow within the connecting sleeve 41 while maintaining a fixed connection between the rod 42 and the connecting sleeve 41. In other embodiments, the rod 42 can also be fixedly connected to the inner wall of the connecting sleeve 41 via a mounting base.

[0056] The counterweight 43 is slidably sleeved on the rod 42;

[0057] A sealing head 44 is installed on top of the counterweight 43; in this embodiment, the end of the sealing head 44 near the sealing ring 46 is spherical. In some other embodiments, it can also be directly set as a cylindrical sealing block. This embodiment effectively improves the sealing effect by setting a spherical surface on the sealing head 44.

[0058] Tension spring 45, one end of which is fixedly connected to connecting sleeve 41, and the other end of which is fixedly connected to counterweight 43;

[0059] The sealing ring 46 is fixedly installed inside the connecting sleeve 41 and is used to cooperate with the sealing head 44 to seal the connecting sleeve 41;

[0060] When the sum of the component force of the counterweight 43 along the length of the rod 42 and the frictional force between the counterweight 43 and the rod 42 is less than the tension force of the tension spring 45 on the counterweight 43, the tension spring 45 pulls the counterweight 43 towards the sealing ring 46, causing the sealing head 44 to abut against the sealing ring 46. When the drainage container 1 is horizontal or nearly horizontal, the tension spring 45 pulls the counterweight 43 towards the sealing ring 46, causing the sealing head 44 to abut against the sealing ring 46, thus automatically sealing the connecting sleeve 41 and effectively preventing liquid from entering the negative pressure suction ball 3.

[0061] It should be noted that in this embodiment, in the vertical state, the counterweight 43 stretches the tension spring 45 and is located at the very end of the rod 42. Furthermore, counterweights 43 of different weights can be set according to different needs, so that when the drainage container 1 is at a preset tilt angle, the sealing head 44 abuts against the sealing ring 46, sealing the negative pressure connector 13. It should be noted that when the sealing head 44 abuts against the sealing ring 46, the weight of the counterweight 43 is greater than the sum of the tension force of the tension spring 45 and the maximum suction force generated by the negative pressure suction ball 3, so that the counterweight can automatically move downwards after the position of the drainage container 1 is adjusted.

[0062] In this embodiment, the counterweight 43 has a through hole 431, and the rod 42 passes through the through hole 431. Sliding elements 5 are installed at both the upper and lower ends of the counterweight 43. The counterweight 43 is slidably connected to the rod 42 via the sliding elements 5, which reduce the friction between the counterweight 43 and the rod 42. Reducing the friction between the counterweight 43 and the rod 42 facilitates the tension spring 45 pulling the counterweight 43 along the rod 42. In this embodiment, the sliding element 5 includes a ring 51 and multiple balls 52 disposed on the inner circumference of the ring 51. The ring 51 is fixedly connected to the counterweight 43. In other embodiments, a groove and a slider with relatively low friction can also be provided between the counterweight 43 and the rod 42.

[0063] In this embodiment, an annular airbag 6 is fixedly mounted on the counterweight 43. The annular airbag 6 is located between the counterweight 43 and the sealing head 44. When there is too much liquid inside the drainage container 1, the annular airbag 6 is floated by the liquid, providing buoyancy. The auxiliary tension spring 45 pulls the counterweight 43 upward, causing the sealing head 44 to abut against the sealing ring 46. After excessive liquid accumulation, the annular airbag 6 is floated by the liquid, providing buoyancy. It then cooperates with the tension spring 45 to cause the sealing head 44 to abut against the sealing ring 46, automatically sealing the connecting sleeve 41.

[0064] In this embodiment, the top of the connecting sleeve 41 is provided with an installation cavity 412, in which a battery 71, a buzzer 72, and a warning light 73 are fixedly installed. The sealing head 44 is provided with an energizing ring 74, and the connecting sleeve 41 is provided with a first electrode plate 751 and a second electrode plate 752. Both the first electrode plate 751 and the second electrode plate 752 are electrically connected to the battery 71. When the sealing head 44 pushes the energizing ring 74 upward and it comes into contact with the first electrode plate 751 and the second electrode plate 752, the battery 71 supplies power to the buzzer 72 and the warning light 73, and the buzzer 72 and the warning light 73 start to work, reminding the patient to adjust the position of the drainage container 1 or drain the accumulated fluid in the drainage container 1.

[0065] In this embodiment, a protective component 8 is provided in the drainage container 1 at the position corresponding to the negative pressure connector 13. The protective component 8 forms a protective area in the drainage container 1. The bottom of the rod 42 is located in the protective area. The protective area is used to prevent the liquid flowing in from the liquid inlet connector 11 from splashing directly onto the sealing component 4, and to prevent the liquid from entering the negative pressure suction ball 3.

[0066] In this embodiment, the protective component 8 includes a first baffle 81 and a second baffle 82. The first baffle 81 is located between the liquid inlet connector 11 and the negative pressure connector 13, and the second baffle 82 is located below the sealing assembly 4. The first baffle 81 is used to block liquid splashed from the direction of the liquid inlet connector 11, and the second baffle 82 is used to block liquid splashed from the bottom of the drainage container 1. In some other embodiments, only the first baffle 81 may be provided.

[0067] In this embodiment, the second baffle 82 is inclined downwards from the end furthest from the first baffle 81 towards the end closest to the first baffle 81. This facilitates the drainage of accumulated liquid within the protected area. In other embodiments, the second baffle 82 can also be horizontally positioned, leaving a gap between the first baffle 81 and the second baffle 82.

[0068] In this embodiment, the connecting sleeve 41 includes an upper sleeve body 413 and a lower sleeve body 414. The upper sleeve body 413 and the lower sleeve body 414 are sealed and fixedly connected. The mounting cavity 412 is formed at the connection between the upper sleeve body 413 and the lower sleeve body 414, which facilitates the replacement of the battery 71. In some other embodiments, a storage battery 71 may also be provided, and a charging structure may be equipped.

[0069] The working principle of this embodiment is as follows:

[0070] When the drainage container 1 is in a vertical position, the weight of the counterweight 43 causes the tension spring 45 to stretch and be located at the end of the rod 42.

[0071] When the drainage container 1 is tilted, the sum of the component force of the weight of the counterweight 43 along the length of the rod 42 and the frictional force between the counterweight 43 and the rod 42 is less than the tension force of the tension spring 45 on the counterweight 43. The tension spring 45 pulls the counterweight 43 towards the sealing ring 46 and drives the sealing head 44 to abut against the sealing ring 46, so that the connecting sleeve 41 automatically seals and prevents the accumulated liquid from entering the negative pressure suction ball 3.

[0072] When the amount of liquid inside the drainage container 1 is too large, when it is immersed to the position of the annular airbag 6, the annular airbag 6 is floated by the liquid to provide buoyancy, and the auxiliary tension spring 45 pulls the counterweight 43 to move upward, so that the sealing head 44 abuts against the sealing ring 46, automatically sealing the connecting sleeve 41.

[0073] When the sealing head 44 pushes the energized ring 74 upward and makes contact with the first electrode plate 751 and the second electrode plate 752, the battery 71 supplies power to the buzzer 72 and the warning light 73. The buzzer 72 and the warning light 73 start to work, reminding the patient to adjust the position of the drainage container 1 or drain the accumulated fluid in the drainage container 1.

[0074] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications and substitutions should be covered within the scope of the claims of the present invention.
