[0035] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts should fall within the scope of protection of the present invention.

[0036] As described in the background art, the conventional method of fixing the catheter by clamping can easily cause the catheter to be crushed, resulting in deformation or blockage of the internal passage.

[0037] In order to solve this technical problem, the present invention provides a catheter fixing device for gastrointestinal surgery, which is used in gastrointestinal surgery nursing.

[0038] Specifically, please refer to Figures 1-6 The gastrointestinal surgical catheter fixing device specifically includes: a support seat 1, a support seat 2 101 arranged outside the support seat 1 and a Velcro 102 arranged on the support seat 2 101, and also includes a fixing mechanism 2 arranged on the support seat 2 101 and a sliding mechanism 3 arranged on the support seat 1;

[0039] The fixing mechanism 2 includes a strip-shaped airbag 201 provided on the outside of the support seat 1, a limiting component 204 provided on the support seat 2 101, and an adjusting component 205 provided on the support seat 2 101;

[0040] The sliding mechanism 3 includes a sliding column 301 provided on the support base 1, a sliding base 302 slidably provided on the sliding column 301, and an expansion component 304 provided on the support base 1.

[0041] The present invention provides a gastrointestinal surgical catheter fixing device, which aims to solve the problem in the prior art of using a clamping method to fix the catheter, which easily causes the catheter to be crushed, resulting in deformation or blockage of the internal passage. The present invention provides a fixing mechanism 2 and a sliding mechanism 3, which drives the strip-shaped airbag 201 to wrap around the outside of the catheter, so that the friction between the strip-shaped airbag 201 and the catheter gradually increases, thereby achieving the situation where the catheter will not be deformed during clamping and fixing.

[0042] The fixing mechanism 2 is provided, and the ratchet 202 cooperates with the pawl 2042 to make the sliding column 301 vibrate, thereby achieving the vibration of the device, solving the problem of blood circulation problems caused by wearing the device for a long time in the prior art.

[0043] By means of the sliding mechanism 3, the ratchet 202 is driven to slide downward, so that the bar magnet 305 squeezes the catheter, thereby pushing and crushing the obstruction in the catheter, thereby solving the problem of catheter obstruction in the prior art.

[0044] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0045] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein may be combined with each other.

[0046] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0047] Example 1, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6 A catheter fixing device for gastrointestinal surgery, wherein the fixing mechanism 2 further comprises a ratchet 202 slidably arranged in the support seat 2 101, the end of the ratchet 202 is provided with a push table 203, the push table 203 is slidably arranged on the support seat 2 101, the two ends of the sliding column 301 are respectively connected to the support seat 1 and the support seat 2 101, and the catheter is located in the center of the device, such as Figure 1 As shown, the support base 2 101 is fixed to the waist of the human body by the Velcro 1 102, and the push-up platform 203 is rotated. The push-up platform 203 drives the ratchet 202 to rotate synchronously, and the ratchet 202 drives the strip airbag 201 to wrap around the outside of the catheter. The friction between the strip airbag 201 and the catheter gradually increases with the number of turns of the strip airbag 201, thereby fixing the catheter.

[0048] Furthermore, a plurality of strip-shaped airbags 201 are provided, and the plurality of strip-shaped airbags 201 are distributed on the ratchet 202 in a circular array. The strip-shaped airbags 201 are arranged in a circular row, so that the strip-shaped airbags 201 and the catheter are evenly stressed.

[0049] Furthermore, the limiting component 204 includes a rotating shaft 2041 rotatably mounted on the second support base 101. A pawl 2042 is disposed on the outer side of the rotating shaft 2041. The ratchet 202 and the pawl 2042 are adapted to each other. The rotating shaft 2041 is connected to the second support base 101 via a torsion spring. The pawl 2042 limits the position of the ratchet 202, preventing the ratchet 202 from resetting. This prevents the strip airbag 201 from resetting and causing the catheter to become loose during operation.

[0050] Furthermore, a protrusion 2043 is provided at the bottom of the pawl 2042, and the protrusion 2043 is adapted to the sliding column 301. When the pushing platform 203 is rotated, the pushing platform 203 drives the ratchet 202 to rotate synchronously, and the ratchet 202 drives the pawl 2042 to swing. When the pawl 2042 swings and is reset by the elasticity of the torsion spring, the protrusion 2043 on the pawl 2042 hits the sliding column 301. Since the sliding column 301 is connected to the support base 1, the support base 1 vibrates. The vibration of the support base 1 promotes blood circulation at the connection between the catheter and the human body, thereby preventing complications when the patient uses the device.

[0051] Furthermore, the adjusting component 205 includes a rotatable rotating ring 2051, which is connected to the pawl 2042 via a rope 2052. By rotating the rotating ring 2051, the rotating ring 2051 pulls the rope 2052, and the rope 2052 drives the pawl 2042 out of engagement with the ratchet 202, thereby releasing the limit of the ratchet 202 by the pawl 2042. When the push table 203 is rotated, the ratchet 202 rotates synchronously, which can be used to drive the ratchet 202 to reset. At the same time, when the sliding seat 302 slides along the sliding column 301, the rotating ring 2051 is used to limit the sliding seat 302.

[0052] When the pushing platform 203 is rotated through the fixing mechanism 2, the pushing platform 203 drives the ratchet 202 to rotate synchronously, so that the strip airbag 201 fixes the catheter. When the ratchet 202 cooperates with the pawl 2042, the protrusion 2043 on the pawl 2042 hits the sliding column 301, and the vibration of the sliding column 301 is transmitted to the support seat 1. The support seat 1 vibrates synchronously, thereby promoting blood circulation at the connection between the catheter and the human body. The rotating ring 2051 can be used to drive the ratchet 202 to reset, which can be used to release the restriction of the strip airbag 201 on the catheter.

[0053] Example 2 further optimizes the gastrointestinal surgical catheter fixing device provided in Example 1. Specifically, Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, the sliding mechanism 3 also includes a second Velcro 303 provided on the sliding seat 302. The connection between the strip airbag 201 and the bottom of the sliding seat 302 is connected to the outside world and is fixed to the waist of the person through the second Velcro 303, so that the support seat 1 and the support seat 2 101 fit the waist of the human body. When the second Velcro 303 is lifted upward, the second Velcro 303 drives the sliding seat 302 to slide along the sliding column 301. When the bottom of the sliding seat 302 is separated from the fit with the support seat 1, the strip airbag 201 is connected to the outside world. When the bottom of the sliding seat 302 is fit with the support seat 1, the strip airbag 201 is disconnected from the outside world, thereby preventing the strip airbag 201 from being deflated due to long-term use.

[0054] Furthermore, the unfolding component 304 includes a hole 3041 provided on the support seat 1, and a shielding portion 3042 is provided at the bottom of the sliding seat 302. The shielding portion 3042 is adapted to the hole 3041. When the Velcro 2 303 is lifted upward, the Velcro 2 303 drives the sliding seat 302 to slide along the sliding column 301, and the shielding portion 3042 on the sliding seat 302 is released from blocking the hole 3041, so that the hole 3041 is exposed, and the connection between the catheter and the human body is exposed, making it easier for medical staff to clean the connection between the catheter and the human body.

[0055] Furthermore, the support seat 1, the sliding seat 302 and the shielding portion 3042 are all made of transparent materials. During normal use, the flow inside the catheter can be observed through the support seat 1, the sliding seat 302 and the shielding portion 3042. When the catheter is blocked, adjustments can be made in time.

[0056] Furthermore, a plurality of bar magnets 305 are slidingly arranged in the ratchet 202, and a plurality of bar airbags 201 are respectively connected to the bar magnets 305. A magnetic ring 306 is arranged in the support seat 101, and the plurality of bar magnets 305 are adapted to the magnetic ring 306. One end of the bar airbag 201 is connected to the bar magnet 305, and the other end is connected to the bottom of the sliding seat 302. In the initial state, the magnetic ring 306 drives the plurality of bar magnets 305 to expand outward through the attraction of the magnetic field, so that the plurality of bar magnets 305 cooperate with the ratchet 202 to form a circle. The catheter slides in this circle. When the catheter is blocked, it rotates and slides down. The push-up platform 203 is moved, and the push-up platform 203 drives the ratchet 202 to slide downward and rotate synchronously. The ratchet 202 drives the strip airbag 201 to wrap around the outside of the catheter, so that the contact area between the strip airbag 201 and the catheter increases, thereby increasing the friction between the strip airbag 201 and the catheter. At the same time, the strip magnetic block 305 breaks away from the attraction of the magnetic field of the magnetic ring 306, and the magnetic force disappears. When the strip airbag 201 is wound around the catheter, because one end connected to the sliding seat is fixed, a sliding groove is provided in the ratchet 202. The tension generated by the winding of the strip airbag 201 will drive the strip magnetic block 305 to shrink toward the inner catheter and slide along the sliding groove in the ratchet 202. Figure 6 As shown, the bar magnet 305 squeezes the catheter, pushing and crushing the blockage in the catheter. The number of turns of the ratchet 202 can adjust the tension generated by the winding of the bar airbag 201 and the degree of squeezing of the catheter by the bar magnet 305.

[0057] Through the sliding mechanism 3, when the Velcro 2 303 is lifted upward, the Velcro 2 303 drives the sliding seat 302 to slide along the sliding column 301, so that the strip airbag 201 is connected to the outside world, preventing the strip airbag 201 from being deflated. At the same time, the shielding part 3042 on the sliding seat 302 is separated from the shielding of the hole 3041, so that the hole 3041 is exposed, and then the connection between the catheter and the human body is exposed, which is convenient for medical staff to clean the connection between the catheter and the human body. When the catheter is blocked, slide downward and rotate the pushing platform 203 to squeeze the catheter through the strip magnetic block 305, so that the blockage is pushed away and crushed.

[0058] The use process of the gastrointestinal surgical catheter fixing device provided by the present invention is as follows:

[0059] When in use, the support base 1 and the support base 2 101 are fixed to the human body by the Velcro 1 02 and the Velcro 2 303, and the jacking platform 203 is rotated, and the jacking platform 203 drives the ratchet 202 to rotate synchronously, and the ratchet 202 drives the strip airbag 201 to wrap around the outside of the catheter. The friction between the strip airbag 201 and the catheter gradually increases according to the number of turns of the strip airbag 201, thereby fixing the catheter. When the medical staff needs to clean the connection between the catheter and the human body, they lift the Velcro 2 303 upwards, and the Velcro 2 303 drives the sliding seat 302 to slide along the sliding column 301, and the blocking portion 3042 on the sliding seat 302 is separated from the blocking of the hole 3041, so that the hole 3041 is exposed, and then the connection between the catheter and the human body is exposed, which is convenient for the medical staff to clean the connection between the catheter and the human body. At the same time, the bottom of the sliding seat 302 is separated from the contact with the support base 1, and the strip airbag 201 is connected to the outside world. To prevent the strip airbag 201 from being deflated when used for a long time, when the catheter is blocked, the pushing platform 203 is rotated and slid downward, and the pushing platform 203 drives the ratchet 202 to slide downward and rotate synchronously, and the ratchet 202 drives the strip airbag 201 to wrap around the outside of the catheter, thereby increasing the contact area between the strip airbag 201 and the catheter, thereby increasing the friction between the strip airbag 201 and the catheter. At the same time, the strip magnet 305 is separated from the attraction of the magnetic field of the magnetic ring 306, and the magnetic force disappears. When the strip airbag 201 is wound around the catheter, because one end connected to the sliding seat is fixed, a sliding groove is provided in the ratchet 202. The tension generated by the winding of the strip airbag 201 drives the strip magnet 305 to retract towards the inner catheter and slide along the sliding groove in the ratchet 202, so that the strip magnet 305 squeezes the catheter, pushing and crushing the blockage in the catheter.
