[0035] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme 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 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 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 channel.

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

[0038] Specifically, please refer to Figure 1-Figure 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 arranged outside the support seat 1, a limiting component 204 arranged on the support seat 2 101, and an adjusting component 205 arranged on the support seat 2 101;

[0040] The sliding mechanism 3 includes a sliding column 301 arranged on the support seat 1, a sliding seat 302 slidably arranged on the sliding column 301, and an unfolding component 304 arranged on the support seat 1.

[0041] The gastrointestinal surgical catheter fixing device provided by the present invention is designed to solve the problem that the catheter is easily crushed and the internal passage is deformed or blocked by fixing the catheter by clamping in the prior art. The present application provides a fixing mechanism 2 and a sliding mechanism 3, and 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 that the catheter will not be deformed when clamped and fixed.

[0042] By setting the fixing mechanism 2, the ratchet 202 cooperates with the pawl 2042 to make the sliding column 301 vibrate, thereby realizing the vibration of the device, and solving the problem of blood arrhythmia caused by wearing the device for a long time in the prior art.

[0043] By setting the sliding mechanism 3, the ratchet wheel 202 is driven to slide downward, so that the bar magnet 305 squeezes the catheter, thereby pushing and crushing the obstruction in the catheter, 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 in conjunction with 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 in the embodiments 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, further definition and explanation thereof is not required 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 a support seat 101, an end of the ratchet 202 is provided with a push table 203, and the push table 203 is slidably arranged on the support seat 101, and the two ends of the sliding column 301 are respectively connected to the support seat 1 and the support seat 101, and the catheter is located in the central part of the device, such as Figure 1 As shown, the support seat 2 101 is fixed to the waist of the human body by the Velcro 1 102, and the push platform 203 is rotated, and the push 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;

[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, and the strip-shaped airbags 201 are arranged in a circular array, so that the strip-shaped airbags 201 and the catheter are subjected to uniform force;

[0049] Furthermore, the limiting component 204 includes a rotating shaft 2041 rotatably arranged on the second support seat 101, a pawl 2042 is arranged 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 seat 101 through a torsion spring, and the pawl 2042 limits the ratchet 202 to prevent the ratchet 202 from resetting, so that when the strip airbag 201 is working, the strip airbag 201 will not be reset to cause the catheter to loosen;

[0050] Furthermore, a protrusion 2043 is provided at the bottom of the pawl 2042, and the protrusion 2043 and the sliding column 301 are adapted to each other. When the push platform 203 is rotated, the push 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 seat 1, the support seat 1 vibrates, and the blood circulation at the connection between the catheter and the human body is promoted through the vibration of the support seat 1, so as to prevent the occurrence of complications when the patient uses the device;

[0051] Further, the adjusting component 205 includes a rotating ring 2051 which is rotatably arranged. The rotating ring 2051 is connected to the pawl 2042 through 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 to disengage from 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] Through the fixing mechanism 2, when the pushing platform 203 is rotated, 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 to promote 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, and can be used to release the limitation 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 arranged on the sliding seat 302, and 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 second support seat 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 in fit with the support seat 1, the strip airbag 201 is not connected to the outside world, so as to prevent the strip airbag 201 from being deflated due to long-term use.

[0054] Furthermore, the unfolding component 304 includes a hole 3041 arranged on the support seat 1, and a shielding portion 3042 is arranged at the bottom of the sliding seat 302, and 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 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;

[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 conditions 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 mutually 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, and 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 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 pulling force 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 strip magnet 305 squeezes the catheter, pushes and crushes the blockage in the catheter, and the tension generated by the winding of the strip airbag 201 and the degree of squeezing of the catheter by the strip magnet 305 can be adjusted by the number of turns of the ratchet 202.

[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, squeeze the catheter through the strip magnetic block 305, so that the blockage is pushed 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 seat 1 and the support seat 2 101 are fixed on the human body by the Velcro 1 102 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 part 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 fit with the support seat 1, and the strip airbag 201 is connected to the outside. To prevent the strip airbag 201 from being deflated when used for a long time, when the catheter is blocked, the push platform 203 is rotated and slid downward, and the push 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, so that the contact area between the strip airbag 201 and the catheter is increased, thereby increasing the friction between the strip airbag 201 and the catheter. At the same time, the strip magnetic block 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 pulling force generated by the winding of the strip airbag 201 will drive the strip magnetic block 305 to shrink in the direction of the inner catheter and slide along the sliding groove in the ratchet 202, so that the strip magnetic block 305 squeezes the catheter, pushes and crushes the blockage in the catheter.
