Abstract
Description
Technical Field
[0001] This utility model belongs to the field of decompression tube technology, specifically relating to a gastrointestinal decompression tube. Background Technology
[0002] Gastrointestinal decompression is a widely used clinical medical procedure, commonly used for patients in postoperative recovery, those with gastrointestinal obstruction, and those with acute gastric dilatation. By using a gastrointestinal decompression tube to drain gas, fluid, and accumulated contents from the patient's gastrointestinal tract, it effectively reduces internal pressure, promotes the recovery of gastrointestinal function, and reduces related complications. However, traditional gastrointestinal decompression tubes have certain limitations in their design. Typically, the tube tip is merely a drainage device, lacking a fixation function at the insertion site. This makes it prone to slippage during patient movement or gastrointestinal peristalsis, affecting drainage effectiveness and potentially requiring secondary procedures, increasing patient discomfort.
[0003] In existing technologies, to achieve effective fixation of gastrointestinal decompression tubes, some products attempt to add auxiliary devices, such as balloons or anchoring structures, to the tube tip. While balloons can fix the decompression tube for a short time, the inflation or deflation process is complex and may cause mucosal damage; anchoring structures generally suffer from inflexible design and significant tissue trauma. Furthermore, some improved products attempt to fix the tube by adding external sutures or hooks, but these designs often rely on a high level of operational skill, placing higher demands on the technical expertise of medical personnel, and may still affect the effectiveness due to insecure fixation. Therefore, there is an urgent need for a gastrointestinal decompression tube that can balance fixation reliability, flexibility, and ease of operation to further improve the safety and efficiency of clinical use. Utility Model Content
[0004] To address the above problems, this utility model provides a gastrointestinal decompression tube.
[0005] The technical solution provided by this utility model is as follows:
[0006] A gastrointestinal decompression tube includes a tube body, a tube head, and several first side holes opened on the tube body. A coil is provided at the tube head. A metal clip clamps the coil and inserts it into the digestive tract, and fixes it to the mucosa on the side of the wound opening.
[0007] In some implementations, the diameter of the coil is 5 mm.
[0008] In some implementations, the coil is a movable coil, which is tightened and fixed to a metal clamp under force.
[0009] In some implementations, the coil is fixed to the tube end.
[0010] In some embodiments, a second side hole is provided at the tube head, and the coil is formed by knotting the end of a thread. The end of the coil is located outside the second side hole, and the thread at the other end of the coil extends into the second side hole and passes through the tube body to be fixed to the other end of the tube body.
[0011] In some implementations, the tube body and tube head are made of silicone or polyvinyl chloride.
[0012] In some implementations, the outer wall of the tube is provided with graduations.
[0013] In summary, the beneficial effects of this utility model are as follows:
[0014] (1) This utility model effectively solves the shortcomings of traditional decompression tubes in terms of fixation by designing a coil structure at the tube head of the gastrointestinal decompression tube. The introduction of the coil provides a simple and reliable fixation method, enabling the decompression tube to be firmly attached to the wound or target site in the gastrointestinal tract, avoiding the risk of tube slippage.
[0015] (2) The present invention connects the tube body and the endoscopic biopsy forceps through a coil, and the decompression tube can be inserted into the digestive tract along with the endoscopic biopsy forceps, which facilitates the insertion of the decompression tube.
[0016] (3) The design of the movable coil in this utility model allows medical personnel to adjust the tightness of the coil according to the specific clinical situation, which has high flexibility and is suitable for the fixation needs of different parts and wounds. The design of the fixed coil simplifies the operation process through integrated molding, and improves the stability and ease of use of the product. Attached Figure Description

[0022] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.
[0023] Example 1
[0024] like Figure 2-3 As shown, the gastrointestinal decompression tube provided in this embodiment includes a tube body 1, a tube head 2, a coil 4, and several side holes opened on the tube body 1. The tube body 1 and the tube head 2 are both made of medical-grade silicone or polyvinyl chloride material, which has good biocompatibility and mechanical properties. In clinical surgery, a gastric tube can be directly used to form the tube body 1 and the tube head 2.
[0025] In this embodiment, the coil 4 is formed by knotting the end of a piece of sewing thread 6. One end of the coil 4 extends outside the second side hole 5 of the tube head 2, and the other end passes through the second side hole 5 via the sewing thread 6, extending to the other end of the tube body 1 and fixed to the tail of the tube body 1. This design allows the coil 4 to be tightened by the metal clamp under force.
[0026] Among them, the coil 4 is a movable coil 4, which is fixed by the suture 6 passing through the second side hole 5 of the tube head 2 and extending to the tail end of the tube body 1. The tightness of the coil 4 is adjusted by applying force with a metal clamp, thereby achieving reliable fixation of the mucosa on the wound opening side.
[0027] Please refer to Figure 3 The movable coil 4 is specifically formed as follows: the end of the suture 6 is designed as a ring, and the other end of the suture 6 passes through the ring, with the suture 6 and the ring surrounding each other to form the coil 4. This design allows for a large adjustment range of the coil 4 during insertion and fixation, making it easier for doctors to optimize the position and tightness of the coil 4 according to the actual situation. The diameter of the coil 4 is 5 mm, a moderate size that ensures sufficient fixation force while avoiding excessive pressure or damage to the mucosa.
[0028] In practice, the doctor inserts the coil 4 into the patient's digestive tract using clamps and endoscopic biopsy forceps. Once the coil 4 reaches the wound opening, external traction sutures 6 are used to gradually contract the coil 4 until it is fixed to the metal clamp, which in turn is fixed to the wound opening mucosa. At this point, the coil 4 is firmly attached to the wound opening mucosa. This method effectively secures the coil 4 to the decompression tube and prevents surgical failure due to accidental dislodgement. Furthermore, the graduations on the tube body 1 visually indicate the insertion depth, providing crucial reference for the procedure.
[0029] The first side holes 3 on the tube body 1 and the second side holes 5 on the tube head 2 are designed as ventilation and drainage channels, which can effectively reduce the accumulation of fluid and gas in the gastrointestinal tract. The number and spacing of the first side holes 3 are optimized according to clinical needs, which can ensure sufficient drainage effect and avoid blockage, thereby further improving the stability and safety of the device.
[0030] The structure of this embodiment allows for dynamic adjustment of the coil 4's position during operation, ensuring that the coil 4 is securely fixed in the target location. The movable coil 4 design prevents dislodgement or wound damage due to improper fixation. Furthermore, the through-structure of the suture 6 facilitates subsequent removal of the tube 1, reducing secondary injury to the patient.
[0031] Example 2
[0032] Please refer to Figure 1 This embodiment provides another method for fixing the coil 4 based on embodiment 1. The coil 4 is fixed to the tube head 2 using an integrated molding design. The coil 4 is directly fused to the tube head 2 using high-temperature molding technology. Of course, the coil 4 can also be fixed to the tube head 2 by drilling or perforating.
[0033] This method simplifies the procedure and is particularly suitable for emergency situations requiring rapid intubation. The coil 4 is secured via its direct connection to the tube tip 2. During the procedure, the operator uses a metal clamp to hold a portion of the coil 4 while slowly inserting the tube body 1 and endoscopic biopsy forceps into the digestive tract. When the coil 4 reaches the mucosa on the wound opening side, it is clamped to the mucosal surface using the metal clamp. The doctor simply needs to gently press the coil 4 against the wound mucosa surface with the metal clamp to complete the fixation. Because the coil 4 requires no adjustment, its positioning stability is high, maintaining good fixation even during patient movement or slight activity.
[0034] This fixation method simplifies clinical procedures, eliminating the need for external force to adjust the position of coil 4, making it suitable for scenarios with tight schedules or requiring rapid insertion. The one-piece molded coil 4 design ensures high durability of the decompression tubing.
[0035] In this embodiment, a second side hole 5 is also provided on the tube head 2. The design of these side holes helps to improve the efficiency of decompression and drainage. The first side holes 3 on the tube body 1 are evenly distributed. By optimizing the combination of hole diameter and number, the air venting and fluid drainage performance of the tube body 1 can be significantly enhanced. This design can quickly relieve the patient's gastrointestinal pressure and reduce the risk of infection from fluid accumulation. The integrated coil 4 design not only enhances the overall durability of the decompression tube but also avoids potential problems caused by improper adjustment of the suture 6.
