Description

Technical Field

[0001] This invention relates to the field of abdominal drainage technology, and more specifically, to an abdominal drainage fixation device for gastrointestinal tumors. Background Technology

[0002] If a tumor is present in the abdominal cavity, surgery should be performed as needed. Abdominal surgery requires a larger incision and is associated with local fluid leakage and excessive blood leakage, increasing the risk of surgical site infection. The abdominal cavity is monitored according to the patient's condition, and a drainage tube or collateral tube is placed. After the patient is transferred to the ward, the nature and amount of drainage are observed and recorded. If no drainage fluid flows from the tube, it may be blocked. If the drainage fluid is blood, flows rapidly, or flows in large quantities, the doctor should be notified immediately. During abdominal drainage, most drainage tubes are secured to the puncture site with tape. Abdominal drainage tubes are quite long. After being inserted into the abdominal cavity, they remain at least 20-40 cm outside the body. Therefore, if the abdominal drainage tube is not secured, it can easily become loose. This loosening not only worsens the patient's pain but can also cause the end of the drainage tube to shift.

[0003] Most drainage tube fixation devices currently in use employ a combination of fixing tape and fixing rope to secure the drainage tube to the patient's body surface. However, such fixation devices are too rudimentary, have poor fixation effect, and the tape is prone to detaching from the patient's body surface. In view of this, the present invention provides an abdominal drainage fixation device for gastrointestinal tumors. Summary of the Invention

[0004] The purpose of this invention is to provide an abdominal drainage and fixation device for gastrointestinal tumors, thereby solving the above-mentioned problems.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an abdominal drainage and fixation device for digestive tract tumors, comprising a base chamber, waist belts connected to both sides of the base chamber, a box connected to the top of the base chamber, drainage holes provided at the bottom of the box and the base chamber, and a fixing component provided inside the box for fixing the drainage tube.

[0006] The present invention is further configured such that: the fixing component is a first fixing component, the first fixing component includes a micro motor, the output end of the micro motor is connected to a connecting rod, the end of the connecting rod away from the micro motor is rotatably connected to the housing, the connecting rod is provided with two symmetrically arranged threads, and the two threads are in opposite directions, the two threaded areas of the connecting rod are threadedly connected to a nut rod, the middle of the nut rod is rotatably connected to a guide rod, the guide rod is rotatably connected to the housing, and the inner side of the nut rod is fixedly connected to a drainage tube fixing component.

[0007] The present invention is further configured such that the drainage tube fixing component is arc-shaped or V-shaped.

[0008] The present invention is further configured such that: the first fixing component further includes a limiting ring, the limiting ring is fixedly connected to the housing, and the connecting rod is provided with limiting blocks on both sides of the limiting ring.

[0009] The present invention is further configured such that: the bottom compartment has multiple cavities on both sides of the drainage hole, and the surface of the bottom compartment is provided with a zipper, which is used to open the cavities inside the bottom compartment.

[0010] The present invention is further configured such that: the top of the casing is provided with a cover, the cover includes a first cover and a second cover, both the first cover and the second cover are hinged to the casing, and the first cover and the second cover have a notch on the side away from the waist belt, the two together forming a circular notch.

[0011] The present invention is further configured such that the belt is connected by a buckle.

[0012] The invention is further configured such that the belt is connected via Velcro.

[0013] The present invention is further configured such that: the fixing component is a second fixing component, the second fixing component includes a connecting column, the connecting column is fixedly connected to an airbag, and the airbag is connected to a micro air pump.

[0014] The present invention is further configured such that the airbag is C-shaped.

[0015] In summary, the present invention has the following beneficial effects:

[0016] Compared to traditional tape or fixing ropes, the active fixation method driven by a motor or controlled by a pneumatic pump offers controllable and secure force, significantly reducing the swaying of the drainage tube outside the body. This invention employs two methods for initial fixation. First, a micro-motor drives a connecting rod with reverse threads, causing the nut rod and drainage tube fixing component to move synchronously inward, clamping and fixing the drainage tube. Second, a pneumatic compression fixation component (second fixation component) is designed: a micro-pneumatic pump inflates a C-shaped pneumatic balloon, using the balloon's expansion to evenly compress and fix the drainage tube. Both fixation methods can be selected based on the actual clinical situation or the patient's comfort requirements.

[0017] Meanwhile, the present invention is designed with a dual fixing structure: after the drainage tube is fixed for the first time by the fixing component, the first and second covers on the top of the box can be closed, and the circular notch formed by the two can fix and seal the drainage tube for the second time.

[0025] 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.

[0026] Example 1:

[0027] An abdominal drainage and fixation device for gastrointestinal tumors, such as Figure 1 and Figure 2 As shown, it includes a bottom compartment 2, with belts 4 connected to both sides of the bottom compartment 2, and a box 1 connected to the top of the bottom compartment 2. Both the bottom of the box 1 and the bottom compartment 2 are provided with drainage holes 5. A fixing component is provided inside the box 1, which is used to fix the drainage tube.

[0028] In this embodiment, as Figure 2 , 3As shown in Figure 4, the fixing component is a first fixing component 110, which includes a micro motor 111. A connecting rod 112 is fixedly connected to the output end of the micro motor 111. The end of the connecting rod 112 away from the micro motor 111 is rotatably connected to the housing 1. Two symmetrically fixed threads are provided on the surface of the connecting rod 112, with opposite directions. A nut rod 113 is threadedly connected to the two threaded areas of the connecting rod 112. A guide rod 117 is rotatably connected to the middle of the nut rod 113, and the guide rod 117 is rotatably connected to the housing 1. A drainage tube fixing component 114 is fixedly connected to the inner side of the nut rod 113. The inner side of the drainage tube fixing component 114 may be provided with silicone to prevent the drainage tube from being pinched during fixing. In this embodiment, two sets of first fixing components 110 are provided to ensure the fixing effect, but it is not limited to two sets.

[0029] In this embodiment, the drainage tube fixing component 114 is arc-shaped or V-shaped, which can better contact and fix the drainage tube.

[0030] In this embodiment, the first fixing component 110 further includes a limiting ring 115, which is fixedly connected to the housing 1. The connecting rod 112 has limiting blocks 116 fixed on both sides of the limiting ring 115. By adding the limiting ring 115 and providing the limiting blocks 116 on the connecting rod 112, the stability of the device's mechanical operation is increased.

[0031] In this embodiment, as Figure 4 and Figure 5 As shown, the bottom compartment 2 has multiple cavities 202 on both sides of the drainage hole 5. The surface of the bottom compartment 2 is provided with a zipper 201, which is used to open the cavities 202 inside the bottom compartment 2. In this embodiment, there are two sets. When the wound is found to be red, swollen, hot, or discharging pus, or accompanied by fever and chills, an antibacterial dressing can be placed in the set near the bottom. The bottom compartment 2 can be made of medical silicone or sterile fabric, and the bottom of the bottom compartment 2 has small ventilation holes, which also facilitates the effect of the antibacterial dressing. At the same time, a hot compress can be placed in the upper layer to relieve discomfort around the wound and avoid direct application to the wound.

[0032] In this embodiment, as Figure 5 As shown, the top of the box 1 is provided with a cover 3, which includes a first cover 301 and a second cover 302. Both the first cover 301 and the second cover 302 are hinged to the box 1, and the first cover 301 and the second cover 302 have a notch on the side away from the waist belt 4. The two together form a circular notch, which is adapted to the size of the drainage tube. During use, it can ensure that a closed space is formed inside the box 1 to prevent dust and other substances from entering and contaminating the wound. It can also achieve secondary fixation of the drainage tube.

[0033] In this embodiment, the belt 4 is connected by a buckle or a Velcro strap.

[0034] The present invention also includes a control board disposed on the surface of the housing 1 (not shown) to control the micro motor 111.

[0035] In use, the drainage tube is inserted into the housing 1 through the drainage hole 5 in the bottom compartment 2. The micro motor 111 is controlled to rotate via the control board, which drives the connecting rod 112. The connecting rod 112, through the thread on its surface, drives the nut rod 113 and the drainage tube fixing piece 114 to move inward simultaneously. The guide rod 117 guides and prevents rotation. The drainage tube is fixed by the drainage tube fixing piece 114. Then, the first cover 301 and the second cover 302 are closed to fix the drainage tube again and prevent dust and other particles from entering the housing 1 and causing wound infection.

[0036] Example 2:

[0037] The difference from Example 1 is that, as Figure 6 As shown, the fixing component is a second fixing component 120, which includes a connecting post 121. An airbag 122 is fixedly connected to the connecting post 121, and the airbag 122 is connected to a miniature air pump. In this embodiment, two sets of airbags 122 are provided, but the number is not limited to two.

[0038] In this embodiment, the airbag 122 is C-shaped and its size is adapted to the drainage tube.

[0039] As above, the drainage tube is inserted into the housing 1 through the drainage hole 5 of the bottom compartment 2. The micro air pump is controlled to inflate the tube through the control board. The drainage tube is fixed by multiple C-shaped airbags 122. Then the first cover 301 and the second cover 302 are closed to fix the drainage tube again, which also prevents dust and other particles from entering the housing 1 and causing wound infection.

[0040] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
