Description

Technical Field

[0001] The utility model relates to the technical field of drainage, in particular to a disposable postoperative drainage tube. Background Art

[0002] Drainage is a necessary step in most surgeries. During the drainage process, poor drainage and blockage of the drainage tube are the most common causes of drainage failure. For example, during abdominal drainage, the oval hole is often blocked by the intestine, mesentery, omentum, fat and other tissues, causing poor drainage, secondary ascites, and large amounts of exudation around the drainage tube. Excessive ascites can easily cause postoperative abdominal distension, intra-abdominal pseudocysts that compress the intestines or blood vessels, intra-abdominal infections and even postoperative intestinal obstruction. Exudation around the drainage tube may cause complications such as wound infection and skin infection.

[0003] For example, the utility model patent with publication number CN204582265U, authorization announcement date August 26, 2015, and titled "Drainage tube that can be flushed and prevented from being blocked and device for conveniently unclogging the drainage tube" discloses a drainage tube that can be flushed and prevented from being blocked and a device for conveniently unclogging the drainage tube. The drainage tube includes a drainage tube body and a flushing tube. The flushing tube and the drainage tube body are an integral structure and are parallel. One end of the drainage tube body is a drainage end, and the other end is a connecting end. The drainage end is provided with a plurality of connecting holes. The flushing tube is provided with a plurality of conducting holes connected with the drainage tube body. The device for unclogging the drainage tube includes the above-mentioned drainage tube and the unclogging device. The utility model inputs flushing fluid through the connecting port of the branch tube to flush the lesion, accelerate the healing of the patient's wound, and dilute the drainage fluid to prevent the drainage tube from being blocked. If both the drainage tube body and the flushing tube are blocked, the dredger rotates into the flushing tube and inputs flushing liquid into the flushing tube to more effectively dredge the flushing tube and the drainage tube body and dilute and discharge the blockage. The dredger has good flexibility and can pass through the bend of the drainage tube to effectively dredge the drainage tube.

[0004] In the prior art, when the drainage tube is blocked, the common solution is to rotate it outside or partially pull it out, hoping to remove the tissue blocking the drainage tube opening, but the effect is often poor. The blockage is often tightly combined with the inner cavity of the drainage tube, which is difficult to aspirate out. Moreover, the blockage is mostly in solid form, which is difficult to disperse and flush out from the opening at the head of the drainage tube, and it is very likely to be blocked again. In addition, during the use of external force, once the drainage tube is unblocked, its instantaneous drainage cavity will experience a large pressure change, which may cause the body tissue to be sucked from the drainage tube opening or opening, or the tissue is overly compressed, causing tissue bleeding or other discomfort.

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] In order to more clearly describe the structures of the embodiments of the present invention, the terms "proximal end" and "distal end" are defined herein as commonly used terms in the field of interventional medicine. Specifically, the "distal end" refers to the end away from the operator during the surgical operation, the "proximal end" refers to the end close to the operator during the surgical operation, the "axial" refers to its length direction, and the "radial" refers to the direction perpendicular to the "axial" direction.

[0024] Reference Figure 1 A disposable postoperative drainage tube provided by an embodiment of the utility model includes a tube body 1 and an expansion device 2. The expansion device 2 has a first state and a second state. In the first state, the expansion device 2 is attached to the tube body 1. In the second state, the expansion device 2 expands into a spherical shape.

[0025] Specifically, Figure 1As shown, the distal end of the tube body 1 (i.e., the end entering the human body) is used to be placed in the abdominal cavity, and the proximal end of the tube body 1 (i.e., the end away from the human body) is connected to the drainage bag. The shape of the tube body 1 is similar to that of an ordinary urinary catheter. A plurality of elliptical holes 3 are provided on the distal end of the tube body 1. The diameter of the elliptical holes 3 is preferably 7 mm. Preferably, four elliptical holes 3 are provided. The four elliptical holes 3 are symmetrically distributed on both sides of the distal end of the tube body 1, and the axial spacing between the four elliptical holes 3 is the same, so as to facilitate the circulation between tissues. The distal end of the tube body 1 is also provided with a plurality of elliptical holes 3. A water inlet pipe 6 is provided, a valve is provided on the distal end of the water inlet pipe 6, the pipeline of the water inlet pipe 6 is connected to the pipe body 1, and the radial dimension of the water inlet pipe 6 gradually decreases, that is, a section of the water inlet pipe 6 extends into the pipe body 1 to form an internal channel of the pipe body 1, and also includes an expansion device 2. Preferably, the expansion device 2 is a water bag, and four water bags are provided, two of which are hemispherical in shape, and the other two are cylindrical in shape. The two cylindrical water bags are in the middle of the two hemispherical water bags, and there are elliptical holes 3 between two adjacent water bags. That is, the drainage hole. When in use, the expansion device 2 is fixedly attached to the outer wall of the tube body 1. At this time, the expansion device 2 is in the first state. After the tube body is sent into the human body, water is filled into the expansion device 2 through the water inlet pipe 6. At this time, the expansion device 2 expands into a spherical shape. The expansion device 2 is in the second state. A gap is formed between two adjacent water bags. At this time, the elliptical hole 3 is just located in the gap, which not only meets the drainage needs, but also protects the elliptical hole 3 from tissues that are easily blocked by it. The tissue is blocked at the edge of the water bag and is difficult to enter the gap, which reduces the probability of the elliptical hole 3 being blocked. When the tube body 1 is to be pulled out at the end of the operation, the valve is first opened to release the water in the water bag outside the body, and it is confirmed that the amount of liquid released is equivalent to the amount of liquid injected, ensuring that the water bag is completely emptied. The expansion device 2 is in the first state again. At this time, the water bag is pulled out, and the expansion device 2 is manually removed from the tube body 1. In this way, the installation and removal of the expansion device 2 are completed manually, and the expansion device 2 is set on the tube body 1 to expand into a spherical shape to protect the elliptical hole 3 from tissues that are easily blocked by it.

[0026] In an optional embodiment, the top edge of the water bag has a plurality of protrusions, and the protrusions are axially extending structures. In a first state, the protrusions fit on the drainage holes, thereby achieving complete closure of the drainage holes. In a second state, the protrusions on both sides are staggered to form a structure that is plugged in sequence, forming a wavy opening at the gap opening, further reducing the probability of solid matter entering the gap.

[0027] The utility model provides a disposable postoperative drainage tube. When in use, the doctor puts the expansion device 2 at the end of the tube body 1, trims it as needed, and puts it in a designated position. At this time, the expansion device 2 is in a first state. After observing that the position of the tube body 1 is correct, the expansion device 2 is put in a second state. At this time, the expansion device 2 expands into a spherical shape. The spherical expansion device 2 can provide a larger space to separate the intestinal tract, omentum and other tissues from the elliptical hole 3 on the tube body 1 as much as possible, thereby reducing the probability of blockage of the tube body 1.

[0028] In another embodiment provided by the present utility model, Figure 1 As shown, the outer wall of the tube body 1 is also provided with scale lines 4. In the prior art, since there is no obvious mark on the tube body 1, it is impossible to grasp the specific length of the tube body 1 remaining in the body. Therefore, when the tube body 1 is adjusted outward, there is a risk of partially pulling out the elliptical hole 3 of the tube body 1. Once the elliptical hole 3 is exposed, the tube body 1 cannot play a normal drainage role. At this time, regardless of whether there is peritoneal effusion, the tube body 1 can only be pulled out, resulting in passive treatment. In this way, the scale lines 4 are provided on the outer wall of the tube body 1, so that the length of the tube body 1 in the body can be clearly grasped, and it is convenient to understand the distance between the expansion device 2 and the elliptical hole 3 and the skin when adjusting the position.

[0029] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
