Description

Technical Field

[0001] The utility model relates to the technical field of catheter fixing, in particular to an intestinal obstruction catheter fixing device. Background Art

[0002] Intestinal obstruction refers to a general term for the inability of intestinal contents to function normally and pass smoothly through the intestines due to various reasons. It is a common surgical acute abdomen. Clinical manifestations include abdominal pain, abdominal distension, vomiting, and cessation of anal gas and defecation. As one of the devices for the treatment of intestinal obstruction, the intestinal obstruction catheter (transnasal type) can reach the jejunum and play a role in rapid decompression and drainage. It uses the gravity of the balloon and the peristalsis of the intestine itself to enable the intestinal obstruction catheter to quickly reach the obstruction site. Negative pressure drainage or drug injection through the catheter can effectively relieve the obstruction and improve the treatment effect.

[0003] The total length of existing intestinal obstruction catheters is three meters, and the tube left outside the body is generally more than one meter long. After the catheter is inserted, it will move downward autonomously with intestinal peristalsis, so the tube outside the body cannot be fixed. A certain length of space must be left for the tube until it falls to the target position and then fixed externally to prevent the intestinal obstruction catheter from sliding down.

[0004] At present, the external fixation device of the intestinal obstruction catheter is only fixed on the face with tape, leaving enough "U"-shaped pipe, but a long section of the pipe is randomly exposed outside, and the length of the reserved pipe is difficult to guarantee the length of the pipe entering the body. Therefore, in the process of the intestinal obstruction catheter entering the body, it is very easy for the pipe to be reserved too long or too short, which requires medical staff to tear off the tape fixed on the face many times to adjust the pipe before fixing it. It is not only very time-consuming and laborious, but also with multiple tearing and fitting, the tape is very likely to become non-sticky, thus affecting the fixation effect of the intestinal obstruction catheter.

Through the above structure, it is convenient to fit the intestinal obstruction catheter through the anti-slip plate, thereby achieving the purpose of fixing the intestinal obstruction catheter.

[0009] An arc-shaped groove is provided at the lower end of the movable plate, and the driving plate and the anti-slip plate are both arranged as arc-shaped plate structures. Through the above structure, the anti-slip plate and the intestinal obstruction catheter can fit more closely, thereby increasing the contact area between the intestinal obstruction catheter and the anti-slip plate.

[0010] The positioning assembly includes a connecting plate and a first plate member. The connecting plate is installed on the upper end of the movable plate. The connecting plate is arranged through the fixed plate. The first plate member is installed on the connecting plate. Through the above structure, it is convenient to drive the movable plate to move up and down through the connecting plate.

[0011] The positioning assembly also includes a positioning rod, a positioning spring and a second plate. The positioning rod is arranged on the first plate, the positioning rod and the positioning spring are connected to each other, the positioning spring and the movable plate are connected to each other, the positioning rod is fitted with the second plate through a snap-fit ​​groove opened on the second plate, and the second plate and the fixed plate are connected to each other.

[0012] A soft silicone layer is provided at the lower end of the anti-slip plate. Through the above structure, the friction effect and contact area between the anti-slip plate and the intestinal obstruction catheter can be effectively increased.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] See also Figure 1-Figure 5 The utility model provides a technical solution: an intestinal obstruction catheter fixing device, comprising a fixing plate 1, fixed straps 2 are fixedly arranged on the left and right sides of the fixing plate 1, guide grooves for sliding the intestinal obstruction catheter are arranged through the middle of the fixing plate 1, a shock absorbing rod 5 is installed on the rear surface of the fixing plate 1, and a soft skin pad 6 is arranged on the rear side of the shock absorbing rod 5;

[0026] When the intestinal obstruction catheter needs to be inserted into the human body, the intestinal obstruction catheter is passed through the catheter groove opened in the middle position of the fixing plate 1, and then the intestinal obstruction catheter on the right side of the fixing plate 1 is sent into the human body through the nasal cavity, and then the fixing plate 1 is fixed to the patient's cheek by the fixing strap 2 (the fixing strap 2 is set as an elastic strap, and different lengths of the fixing strap 2 can be selected according to needs. While ensuring the elastic effect of the fixing strap 2, it can also avoid causing greater squeezing to the patient's face). At this time, the soft skin pad 6 begins to fit closely with the patient's cheek, and the soft skin pad can be ensured under the action of the shock absorbing rod 5. 6 and the support effect between the fixing plate 1 (the soft skin pad 6 is set to be soft and breathable fabric, and the upper and lower ends of the soft skin pad 6 are provided with square convex plates that can be pasted with adhesive tape. Therefore, in order to ensure the stability of the fixing plate 1, adhesive tape can be auxiliaryly pasted to prevent the fixing plate 1 from moving, and the shock-absorbing rod 5 is set to be a sponge material with a buffering and shock-absorbing effect), so that when the soft skin pad 6 fits against the cheek, it can avoid causing a large squeeze on the cheek. The total length of the intestinal obstruction catheter is three meters, and the pipeline generally left outside the body is more than one meter. After insertion, it will move downward autonomously with the intestinal peristalsis pipeline until the intestinal obstruction catheter is sent to the specified length and enters the human body;

[0027] A fixing component 3 is arranged inside the fixing plate 1, and a positioning component 4 is arranged on the upper end of the fixing component 3, and the positioning component 4 is interconnected with the fixing plate 1; the fixing component 3 includes a moving slider 301, a moving plate 302, a pressing plate 303 and a pressing spring 304, and the fixing plate 1 is interconnected with the moving slider 301 through a sliding groove arranged inside it, and the moving slider 301 is symmetrically installed on the moving plate 302, and the pressing plate 303 is slidably arranged on the moving plate 302, and the pressing plate 303 is interconnected with the pressing spring 304, and the pressing spring 304 is interconnected with the moving plate 302; the fixing component 3 also includes a driving plate 305 and an anti-slip plate 306, and the lower end of the pressing plate 303 is interconnected with the driving plate 305, and the lower end of the driving plate 305 is interconnected with the anti-slip plate 306; the lower end of the moving plate 302 is provided with an arc shaped groove, the driving plate 305 and the anti-slide plate 306 are both configured as arc-shaped plate structures; a soft silicone layer is provided at the lower end of the anti-slide plate 306; the positioning component 4 includes a connecting plate 401 and a first plate member 402, the upper end of the movable plate 302 is provided with a connecting plate 401, the connecting plate 401 is arranged on the fixed plate 1, and the first plate member 402 is installed on the connecting plate 401; the positioning component 4 also includes a positioning rod 403, a positioning spring 404 and a second plate member 405, the positioning rod 403 is arranged on the first plate member 402, the positioning rod 403 is connected to the positioning spring 404, the positioning spring 404 is connected to the movable plate 302, the positioning rod 403 is mutually fitted with the second plate member 405 through the engaging groove provided on the second plate member 405, and the second plate member 405 is connected to the fixed plate 1;

[0028] Before delivering the intestinal obstruction catheter into the human body, it is necessary to reserve a certain length of the intestinal obstruction catheter between the human body and the fixing plate 1, and then pull the positioning rod 403 to make the positioning rod 403 start to move away from the first plate 402. Because the positioning rod 403 is equipped with a positioning spring 404, the positioning spring 404 begins to be stretched and deformed until the positioning rod 403 no longer fits with the groove opened on the second plate 405 (at this time, the positioning rod 403 fits with the first limiting groove opened at the upper end of the second plate 405), and then move the connecting plate 401 downward, and the connecting plate 401 begins to slide on the fixing plate 1. Because the movable plate 302 is installed at the lower end of the connecting plate 401, the movable plate 302 begins to move downward until the anti-slide plate 306 fits with the intestinal obstruction catheter, and then the connecting plate 401 continues to move downward. At this time, the driving plate 305 begins to move in the direction close to the movable plate 302. Because the driving plate 305 is installed with a pressing plate 303, the pressing plate 303 and the pressing spring 304 are connected to each other. At this time, the pressing spring 304 begins to be stretched and deformed, and then under the action of the pressing spring 304 restoring the deformation, the pressing spring 304 begins to pull the pressing plate 303 to move in the direction close to the movable plate 302, so that the anti-slide plate The anti-slide plate 306 is arranged in an arc-shaped plate structure, and a soft silicone layer is arranged at the lower end of the anti-slide plate 306, which can effectively prevent the intestinal obstruction catheter from being over-extruded and causing poor drainage of the intestinal obstruction catheter. Then, the positioning rod 403 is released, and under the action of the positioning spring 404 restoring the deformation, the positioning spring 404 begins to pull the positioning rod 403 to move toward the direction close to the first plate 402, until the positioning rod 403 is fitted with the second limiting groove provided at the lower end of the second plate 405, and at this time, the position of the connecting plate 401 can be fixed, thereby ensuring the intestinal obstruction. The catheter is continuously pressed and fixed, and with the peristaltic action of the intestine itself, the intestinal obstruction catheter can quickly reach the obstruction site. When it reaches the designated position, if the reserved length of the intestinal obstruction catheter is too long, pull the positioning rod 403, and then move the connecting plate 401 upward, and then pull the intestinal obstruction catheter on the left side of the fixing plate 1 until the intestinal obstruction catheter between the fixing plate 1 and the human body is in a straightened state, and then move the connecting plate 401 downward to make the anti-slip plate 306 fit tightly with the intestinal obstruction catheter. At this time, it can effectively avoid the reserved intestinal obstruction catheter being too long, causing the pipeline to be accidentally pulled out, affecting the patient's comfort and self-image.

[0029] like Figure 6 , Figure 7As shown, in order to prevent the patient from coughing or vomiting during the introduction process, which may cause the intestinal obstruction catheter to fall out, two one-way gears 7 are installed correspondingly on one side of the fixed plate 1. The one-way gear 7 is a one-way rotating gear. In this embodiment, the rotation direction of the one-way gear 7 is the pipeline delivery direction. The intestinal obstruction catheter 8 is clamped by the two one-way gears 7 so that the intestinal obstruction catheter 8 can only be delivered in one direction. The axle of one of the one-way gears 7 is slidably installed in the strip holes on both sides of the fixed plate 1. A spring is installed on the axle to squeeze the one-way gear 7 against the intestinal obstruction catheter 8. When the intestinal obstruction catheter 8 needs to be removed, the axle 9 of the one-way gear 7 needs to be pulled to keep the one-way gear 7 away from the intestinal obstruction catheter 8. As shown in FIG. Figure 8 As shown, since the intestinal obstruction catheter is very long, the redundant intestinal obstruction catheter 8 located on the outside can be wound around the reel on the reel box 10 for easy storage.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
