Description
Technical Field
[0001] The invention relates to the technical field of medical devices, in particular to a postoperative nursing drainage device for an intensive care unit. Background Art
[0002] Drainage devices play a vital role in postoperative care in the intensive care unit. After surgery, patients often have effusions, blood and other fluids in their abdominal cavity. If they cannot be drained out in a timely and effective manner, the risk of infection will increase and the patient's recovery process will be affected. Therefore, a reliable drainage device is needed to drain these fluids out of the body. The main function of traditional postoperative care drainage devices in intensive care units is to achieve fluid drainage, but in actual use, they face many challenges and problems, and it is difficult to fully meet the needs of efficient and safe care.
[0003] The existing postoperative care drainage device for intensive care units is usually composed of a simple drainage tube and a drainage bag. One end of the drainage tube is inserted into the patient's abdominal cavity, and the liquid is introduced into the drainage bag using gravity or a simple negative pressure principle. The drainage tube is usually fixed by sutures or simple pasting, lacking a stable and flexible fixing structure. The drainage bag is generally replaced by clamping the drainage tube with a clip, and then disassembling and installing it. The structural design is relatively basic, and the convenience and stability of operation are poor.
[0004] In the actual postoperative care scenario of the intensive care unit, the existing drainage devices have obvious shortcomings. First, the drainage tube is not firmly fixed and is prone to bending or falling out. For example, when the patient turns over or moves, the drainage tube will shift or bend due to the simple fixing method, resulting in poor drainage and affecting the discharge of accumulated fluid. Second, the drainage bag is inconvenient to use and replace. When replacing the drainage bag, the method of clamping the drainage tube with a clip is unstable, prone to leakage and contamination, and requires continuous hand-held force during operation, which increases the workload of medical staff. Therefore, the present invention provides a postoperative care drainage device for the intensive care unit to address the shortcomings of the prior art. Summary of the invention
[0005] In view of the deficiencies of the prior art, the present invention provides a postoperative care drainage device for an intensive care unit, which solves the problem that the drainage tube in the drainage device in the prior art is prone to bending and the drainage tube sealing operation is not convenient and stable when replacing the drainage bag.
[0006] To achieve the above objectives, the present invention is implemented through the following technical scheme: a postoperative care drainage device for an intensive care unit, comprising two drainage tubes, two adjacent ends of which are provided with negative pressure regulating valves, one end of one of the drainage tubes being provided with a blocking mechanism, the blocking mechanism comprising a sealing seat, a sealing plug and a limiting assembly, one end of the sealing seat being fixedly connected to one end of one of the drainage tubes, the outer side of the sealing plug being slidably connected to the inner side of the sealing seat, a slot being provided inside the sealing seat, the outer side of the sealing seat being fixedly connected to a guide rod, one end of the guide rod being fixedly connected to a fixed block, the outer side of the sealing plug being fixedly connected to a slider, one end of the sealing plug being fixedly connected to a spring, and the other end of the sealing plug being fixedly connected to a T-shaped arc rod.

[0009] Preferably, the other end of the sealing seat is fixedly connected to a discharge pipe, and a disassembly and assembly mechanism is provided on the outside of the discharge pipe. The disassembly and assembly mechanism includes a fixing ring and a drainage bag. The fixing ring is sleeved on the outside of the discharge pipe, and the drainage bag is located below the fixing ring.
[0010] Preferably, the bottom of the fixing ring is rotatably connected to a combined cover, the top of the drainage bag is fixedly connected to a combined pipe opening, the inner side of the combined cover is threadedly connected to the outer side of the combined pipe opening, and the outer side of the drainage bag is fixedly connected to two hanging rings.

[0014] The present invention provides a postoperative nursing drainage device for an intensive care unit. It has the following beneficial effects:
[0015] 1.

[0024] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0025] Please refer to the attached Figure 1 -Attached Figure 5, an embodiment of the present invention provides a postoperative care drainage device for an intensive care unit, comprising two drainage tubes 1, and a negative pressure regulating valve 20 is installed at the adjacent ends of the two drainage tubes, which can adjust the negative pressure of the drainage. A blocking mechanism is provided at one end of one of the drainage tubes 1, and the mechanism is used to close the drainage tube 1 when the drainage bag 15 is replaced. The blocking mechanism includes a sealing seat 2, a sealing plug 3 and a limiting assembly. One end of the sealing seat 2 is fixedly connected to one end of one of the drainage tubes 1, which ensures a stable connection between the blocking mechanism and the drainage tube 1. The outer side of the sealing plug 3 is slidably connected to the inner side of the sealing seat 2, so that the sealing plug 3 can move flexibly in the sealing seat 2. A slot 11 is provided inside the sealing seat 2 for accommodating one end of the sealing plug 3 to achieve the closure of the drainage tube 1. A guide rod 4 is fixedly connected to the outer side of the sealing seat 2, and a fixed block 5 is fixedly connected to one end of the guide rod 4. The outer side of the sealing plug 3 is fixedly connected with a slider 6, and the inner side of the slider 6 is slidably connected with the outer side of the guide rod 4. This structure enables the sealing plug 3 to slide stably along the guide rod 4 during movement to avoid deviation. At the same time, one end of the sealing plug 3 is fixedly connected with a spring 10, and one end of the spring 10 is fixedly connected with the outer side of the fixing block 5. The spring 10 provides an elastic force for the sealing plug 3, and the other end of the sealing plug 3 is fixedly connected to a T-shaped arc rod 25, the end of the T-shaped arc rod 25 extends to the side wall of the combined cover 14 and is in contact with the combined cover 14 to form a limit. When the limit of the spring 10 is released, the spring 10 will push the sealing plug 3 to insert into the slot 11, and the T-shaped arc rod 25 will separate from the combined cover 14 as the sealing plug 3 moves horizontally. Under normal conditions, the T-shaped arc rod 25 will cooperate with the outer protrusion of the combined cover 14 to limit the combined cover 14 and prevent it from being opened at will. In this way, under the elastic action of the spring 10, not only can the sealing plug 3 close the sealing seat 2, but also the restriction on the combined cover 14 is released while closing, so that the combined cover 14 can rotate, avoiding the sealing seat 2 from opening the combined cover 14 when it is not closed, so that the material in the drainage tube 1 flows out while avoiding the drainage tube 1 from being contaminated. The limit assembly includes two combined plates 7, which are respectively fixedly connected to the outer sides of the sealing plug 3 and the fixed block 5. The outer side of the combination plate 7 outside the sealing plug 3 is rotatably connected with a hook 9, and the outer side recess of another combination plate 7 is fixedly connected with a hanging rod 8. When the outer side of the hook 9 contacts the outer side of the hanging rod 8, the sealing plug 3 can be limited to keep it in the position of opening the drainage tube 1. When the drainage tube 1 needs to be closed, the hook 9 is removed from the outer side of the hanging rod 8, and the spring 10 will push the sealing plug 3 into the slot 11 to achieve the closing function. This operation method is more stable than the traditional method of clamping the drainage tube 1 with hemostatic forceps to close the effect, and the operation does not need to be continuously hand-held and exerted, which is more labor-saving and safe.
[0026] The other end of the sealing seat 2 is fixedly connected with a discharge pipe 12, and the discharge pipe 12 is used to discharge the liquid in the drainage tube 1 into the drainage bag 15. A disassembly and assembly mechanism is arranged on the outside of the discharge pipe 12, and the mechanism works in conjunction with the blocking mechanism. When the drainage bag 15 is replaced, the drainage tube 1 is first closed by the blocking mechanism, and then the drainage bag 15 is disassembled and assembled. The disassembly and assembly mechanism includes a fixed ring 13 and a drainage bag 15. The fixed ring 13 is sleeved on the outside of the discharge pipe 12 to play a role of fixing and supporting. The drainage bag 15 is located below the fixed ring 13 and is used to collect drainage fluid. The bottom of the fixed ring 13 is rotatably connected with a combined cover 14, and the top of the drainage bag 15 is fixedly connected with a combined pipe mouth 16, and the inner side of the combined cover 14 is threadedly connected with the outer side of the combined pipe mouth 16. By rotating the combined cover 14, the separation and connection of the combined cover 14 and the combined pipe mouth 16 can be achieved, so that the drainage bag 15 can be conveniently removed for replacement without causing the drainage tube 1 to twist. The outside of the drainage bag 15 is fixedly connected to two hanging rings 17. The patient can hang the drainage bag 15 on his body with a rope passing through the two hanging rings 17, which is convenient to carry and improves the patient's convenience of movement. The outside of the drainage tube 1 is provided with an anti-bending mechanism, including two arc-shaped guard plates 18. The arc-shaped guard plates 18 are arranged on the outside of the drainage tube 1, which can protect the drainage tube 1 and prevent it from bending during use. Two straps 19 are wrapped around the outside of the two arc-shaped guard plates 18, and the straps 19 are used to fix the two arc-shaped guard plates 18 on the outside of the drainage tube 1 to ensure the stability of the anti-bending mechanism. The outside of the other drainage tube 1 is provided with an anti-falling mechanism, including a right-angle tube 21. The right-angle tube 21 is sleeved on the outside of the drainage tube 1, and a patch 22 is fixedly connected to the outside thereof, and a pressure-sensitive adhesive is provided on one side of the patch 22. When in use, one end of the drainage tube 1 connected to the patch 22 is inserted into the opening of the patient's body, and then the patch 22 is pressed so that the pressure-sensitive adhesive on the back adheres to the patient's skin to achieve preliminary fixation of the drainage tube 1. Two annular blocks 23 are fixedly connected to the outside of the patch 22, and adhesive tape 24 is provided on the outside of the annular block 23. The adhesive tape 24 is passed through the inner hole of the annular block 23 and attached to the patient's skin, and at the same time cooperates with the right-angle tube 21, which can further ensure that the drainage tube 1 at the opening of the patient's skin will not bend or fall off, thereby improving the stability of the drainage tube 1.
[0027] Specifically, first, carefully insert one end of the drainage tube 1 connected to the patch 22 into the opening of the patient's body. This step is the beginning of the entire drainage process. Accurate insertion can ensure that the drainage tube 1 correctly reaches the part of the abdominal cavity that needs drainage, laying the foundation for the subsequent smooth drainage of fluid, blood and other liquids. If the insertion position is inaccurate, effective drainage cannot be achieved, and even unnecessary damage to the patient's body tissues may be caused. Next, press the patch 22 so that the pressure-sensitive adhesive behind it adheres tightly to the patient's skin. The pressure-sensitive adhesive of the patch 22 has good viscosity and fit, and can initially fix the drainage tube 1 on the surface of the patient's body. This can not only prevent the drainage tube 1 from accidentally falling out during the patient's activities, avoid causing secondary damage to the patient and affecting the drainage effect, but also reduce the discomfort of the patient caused by the shaking of the drainage tube 1 to a certain extent. Then, pass the tape 24 through the inner hole of the annular block 23, and stick the tape 24 on the patient's skin. The annular block 23 provides a fixed position and support point for the tape 24, so that the tape 24 can play a more stable role. In this way, the fixing effect of the drainage tube 1 is further enhanced. At the same time, the right-angle tube 21 is sleeved on the outside of the drainage tube 1, and it cooperates with the above-mentioned fixing method to ensure that the drainage tube 1 at the patient's skin opening will not bend. Once the drainage tube 1 is bent, it will hinder the normal flow of the drainage fluid, resulting in poor drainage and affecting the treatment effect. The right-angle tube 21 effectively avoids this situation and ensures the smooth drainage process. Under the action of the arc guard plate 18 and the bandage 19, the outside of the drainage tube 1 is reliably protected. The two arc guard plates 18 are attached to the outside of the drainage tube 1, providing a physical barrier for the drainage tube 1. The bandage 19 is wrapped around the outside of the two arc guard plates 18 to tightly fix them on the drainage tube 1. This protective measure can prevent the drainage tube 1 from bending during daily activities, nursing operations or collisions with external forces. Because once the drainage tube 1 is bent, it is like a pipe blockage, which will cause the drainage fluid to be unable to pass smoothly, making it impossible for the fluid in the abdominal cavity to be discharged in time, causing a series of complications such as infection and increased effusion, and the combination of the arc-shaped guard plate 18 and the strap 19 effectively reduces this risk and ensures the continuity and stability of drainage. The patient can hang the drainage bag 15 on his body with a rope passing through the two hanging rings 17. This design greatly facilitates the patient's daily activities. When the patient needs to move or take care of some basic life, there is no need to worry about the placement of the drainage bag 15, which reduces the inconvenience of movement caused by the drainage device to the patient and improves the patient's quality of life and comfort. At the same time, the drainage bag 15 can be hung stably, and the occurrence of drainage fluid reflux due to shaking or improper position is avoided. When the drainage bag 15 needs to be replaced, the hook 9 needs to be removed from the outside of the hanging rod 8 before replacement. This operation releases the limit of the sealing plug 3, allowing the elastic force of the spring 10 to play a role.Under the elastic force of the spring 10, one end of the sealing plug 3 will be quickly inserted into the slot 11 to block the internal channel of the sealing seat 2. The effect of this is that the drainage tube 1 can be closed to prevent the fluid in the abdominal cavity from continuing to flow out during the replacement of the drainage bag 15, avoiding contamination and infection, and also maintaining the pressure in the abdominal cavity stable. At this time, the T-shaped arc rod will be separated from the outside of the combination cover 14, and then the combination cover 14 is rotated. Since the inner side of the combination cover 14 is threadedly connected to the outer side of the combination pipe mouth 16, the rotation operation can separate the combination cover 14 from the combination pipe mouth 16. This threaded connection design is not only convenient for disassembly and installation, but also does not cause the drainage tube 1 to twist during the separation process. The drainage tube 1 does not twist to ensure that its position in the patient's body is stable, and will not cause additional stimulation and damage to the patient's body tissues, and also avoids affecting the subsequent drainage effect due to the change in the position of the drainage tube 1. At this time, the drainage bag 15 can be easily removed for replacement. After replacing the drainage bag 15, the sealing plug 3 can be pulled outward, and the hook 9 can be hung on the hanging rod 8 again to limit the sealing plug 3. In this way, the drainage tube 1 is restored to be unobstructed, and the drainage process can continue normally. Compared with the traditional method of using hemostatic forceps to clamp the drainage tube 1 to seal it, the effect of this operation method is more stable. The clamping of hemostatic forceps may cause loose sealing or position movement, resulting in leakage, etc., while the present device can more reliably achieve the closing and opening of the drainage tube 1 through the cooperation of the spring 10 and the limiting assembly. In addition, there is no need to continue to hold the hand to exert force during the operation, and medical staff can complete the operation of replacing the drainage bag 15 more easily and safely, thereby improving work efficiency and quality of care.
[0028] Working principle: First, insert one end of the drainage tube 1 connected to the patch 22 into the opening of the patient's body, then press the patch 22 so that the pressure-sensitive adhesive on the back of it sticks to the patient's skin, then use the tape 24 to pass through the inner hole of the annular block 23, and stick it on the patient's skin with the tape 24. At the same time, in cooperation with the right-angle tube 21, it can ensure that the drainage tube 1 at the patient's skin opening will not bend. In addition, under the action of the arc-shaped guard plate 18 and the strap 19, the outside of the drainage tube 1 can be protected to prevent bending. The patient can use a rope to pass through the two hanging rings 17 to hang the drainage bag 15 on the body for easy carrying, and the rotating combination cover 14 can be connected with the combination The separation of the tube mouth 16 will not cause the drainage tube 1 to twist, and the drainage bag 15 can be easily removed for replacement. However, before replacing the drainage bag 15, the hook 9 needs to be removed from the outside of the hanging rod 8, and then under the elastic force of the spring 10, one end of the sealing plug 3 will be inserted into the slot 11 to block the internal channel of the sealing seat 2, so that the drainage tube 1 can be sealed. After replacing the drainage bag 15, the sealing plug 3 can be pulled outward, and the hook 9 can be hung on the hanging rod 8 again to limit the sealing plug 3. This operation method is more stable than the traditional hemostatic forceps that clamp the drainage tube 1 to seal it, and the operation does not require continuous hand-held force, which is more labor-saving and safe.
