Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a disposable intestinal cleaning balloon. Background Art

[0002] Patients in the anorectal department often have blood clots and trauma in their intestines. When performing intestinal surgery on these patients, medical instruments are needed to clean the feces and blood in the intestines to ensure that doctors can perform minimally invasive surgery in the intestines.

[0003] In the prior art, the Chinese utility model with publication number: CN202666171U discloses an intestinal balloon catheter, including a catheter, a Y-shaped three-way connector, a balloon, a knob seat, a knob cover, a traction line and a T-shaped block. The different hardness of the inner and outer catheters of the utility model and the coaxial arrangement can not only maintain the flexibility of the catheter but also maintain the good rigidity of the catheter, and can easily distinguish the inner and outer channels, so that doctors can operate more smoothly without the phenomenon of tube folding and bending due to uneven wall thickness; the catheter adopts a melting head process to process its head end into a smooth round head, reducing the patient's discomfort when the tube enters the human body; the gas injection port and the liquid injection port are provided with self-sealing joints, which play the role of opening and thickening the balloon channels; the existence of the traction line can change the shape of the outer catheter during operation, so that the balloon catheter can enter the cavity with bifurcation or relatively large bending angle.

[0004] The catheter in the above technical solution relies on its own rigidity and flexibility to achieve movement in the intestine. Since the patient's intestine is fragile, the movement of the catheter in the intestine in a non-linear state will inevitably collide with the inner wall of the intestine, making the catheter extremely difficult to transport inward. This is because the catheter lacks the necessary supporting structure inside, and its own strength is not enough to enable the catheter to move smoothly in and out of the intestine. Utility Model Content

[0005] The purpose of the utility model is to provide a disposable intestinal cleaning balloon. By inserting a guide wire inside the catheter, the catheter is supported by the guide wire, and the cleaning balloon inserted into the front end of the colonoscope through the enteroscope clamp channel moves smoothly inside the intestine. It can effectively and accurately clean the feces and blood in the intestinal cavity. It is suitable for patients with poor intestinal preparation and intestinal bleeding, so as to solve the problems raised in the above-mentioned background technology.

[0007] Preferably, a circular arc plug is integrally formed at the front end of the catheter, the plug is connected to the catheter, and the diameter of the plug is the same as the outer diameter of the catheter.

[0008] Preferably, one end of the guide wire passes through the catheter and extends outward from the plug, and the diameter of the guide wire is smaller than the aperture of the through hole.

[0009] Preferably, a control valve is provided inside the branch joint for controlling the opening and closing of the airway.

[0010] Preferably, two groups of elastic sealing flaps are provided at one end of the plug away from the catheter, and the elastic sealing flaps are used to seal one end of the catheter.

[0011] Preferably, two groups of auxiliary balloons are provided on the surface of the inflatable balloon at the tip end, and the auxiliary balloons extend to the outer surface of the inflatable balloon at the tip end. Two groups of channels are integrally formed inside the airway, and the two groups of channels are respectively connected to the auxiliary balloons.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] like Figures 1-2 The disposable intestinal cleaning balloon shown comprises a catheter 1, a tip inflatable balloon 2 and a tail connection part 3, wherein the tip inflatable balloon 2 is located on the outside of one end of the tip of the catheter 1, the catheter 1 is a hollow pipe, an airway 4 for supplying air to the tip inflatable balloon 2 is arranged inside the catheter 1, the tail connection part 3 is fixed to one end of the catheter 1 away from the tip inflatable balloon 2, a through hole 5 communicating with the catheter 1 is arranged at the center of the tail connection part 3, the tail connection part 3 comprises a main joint 31 and a branch joint 32 integrally formed and located on the side of the main joint 31, the branch joint 32 is communicated with the airway 4, a vent hole 6 is opened on the surface of the catheter 1, the vent hole 6 connects the airway 4 with the tip inflatable balloon 2, and a guide wire 7 is inserted inside the through hole 5;

[0028] It is connected to the catheter 1 through the tail connection part 3, and the inflatable balloon 2 at the front end is fixed on the outside of the catheter 1. The inflatable balloon 2 at the front end is inflated through the branch joint 32 of the tail connection part 3, so that the inflatable balloon 2 at the front end is expanded and supported inside the intestine. By pulling the catheter 1, the feces and blood in the intestine are cleaned. The guide wire 7 is inserted into the inside of the catheter 1 to support the catheter 1, so that a soft catheter 1 can be selected to avoid the scraping of the intestinal wall by the catheter 1 in the intestine, thereby aggravating the damage to the intestine.

[0029] The front end of the catheter 1 is integrally formed with an arc-shaped plug 8, which is connected to the catheter 1. The diameter of the plug 8 is the same as the outer diameter of the catheter 1. The arrangement of the arc-shaped plug 8 facilitates the catheter 1 to move through the intestine, reduces the scraping of the intestinal wall by the catheter 1, reduces the damage to the intestine, and facilitates the protection of intestinal patients.

[0030] One end of the guide wire 7 passes through the catheter 1 and extends outward from the plug 8. The diameter of the guide wire 7 is smaller than the aperture of the through hole 5. By limiting the length and diameter of the guide wire 7, it is ensured that the guide wire 7 can be normally inserted into the interior of the catheter 1 to play a stable supporting role, thereby avoiding the guide wire 7 being inserted into a part of the interior of the catheter 1 and unable to support the inflated balloon 2 at the tip end, causing the inflated balloon 2 at the tip end to shake when moving, thereby aggravating the patient's pain.

[0031] A control valve 9 is provided inside the branch joint 32 for controlling the on-off of the airway 4. The on-off control of the airway 4 is conveniently performed through the control valve 9 to ensure that the tip inflation balloon 2 remains in an expanded state after inflation, so as to prevent the tip inflation balloon 2 from being squeezed by the moving catheter 1 or the patient's intestinal peristalsis, causing the tip inflation balloon 2 to shrink and unable to continuously contact the inner wall of the intestine, thereby failing to quickly clean the feces and blood in the intestine.

[0032] Two sets of elastic sealing flaps 10 are arranged at one end of the plug 8 away from the catheter 1. The elastic sealing flaps 10 are used to seal one end of the catheter 1. The setting of the elastic sealing flaps 10 facilitates the sealing of the inner cavity of the plug 8. However, tools can be used to push the sealing flaps outward from the inside of the catheter 1 to open the inner cavity of the plug 8, so that the front and rear ends of the catheter 1 are in an unobstructed state.

[0033] The outer side of the guide wire 7 is clamped with a limiting clip 12, and the limiting clip 12 is located on the outer side of the tail connecting part 3. The setting of the limiting frame is convenient for limiting the guide wire 7 to avoid that when the catheter 1 is pulled back, the guide wire 7 does not move back with the catheter 1, causing the guide wire 7 to pass through the plug 8, resulting in scratches on the intestine when the guide wire 7 moves again.

[0034] A colonoscopy channel 13 is provided on the outside of the catheter 1. The length of the colonoscopy channel 13 is shorter than that of the catheter 1. The setting of the colonoscopy channel 13 facilitates the provision of a passage for the catheter 1 to enter the intestine, thereby reducing secondary damage to the intestine.

[0035] The outer side of the tail connection part 3 is provided with anti-skid patterns. The tail connection part 3 and the catheter 1 are both made of non-ductile medical plastic. The anti-skid patterns provide sufficient friction when the catheter 1 is pulled out.

[0036] Example 2

[0037] like Figures 3-4 The disposable intestinal cleaning balloon shown comprises a catheter 1, a tip inflatable balloon 2 and a tail connection part 3, wherein the tip inflatable balloon 2 is located on the outside of one end of the tip of the catheter 1, the catheter 1 is a hollow pipe, an airway 4 for supplying air to the tip inflatable balloon 2 is arranged inside the catheter 1, the tail connection part 3 is fixed to one end of the catheter 1 away from the tip inflatable balloon 2, a through hole 5 communicating with the catheter 1 is arranged at the center of the tail connection part 3, the tail connection part 3 comprises a main joint 31 and a branch joint 32 integrally formed and located on the side of the main joint 31, the branch joint 32 is communicated with the airway 4, a vent hole 6 is opened on the surface of the catheter 1, the vent hole 6 connects the airway 4 with the tip inflatable balloon 2, and a guide wire 7 is inserted inside the through hole 5;

[0038] Two groups of auxiliary balloons 11 are arranged on the surface of the tip inflatable balloon 2, and the auxiliary balloons 11 extend to the outer surface of the tip inflatable balloon 2. Two groups of channels 14 are integrally formed inside the airway 4, and the two groups of channels 14 are respectively connected to the auxiliary balloons 11. There are three groups of control valves 9 inside the branch joint 32, and the three groups of control valves 9 control the airway 4 and the channel 14 respectively.

[0039] The airway 4 and the channel 14 are controlled respectively by the three groups of control valves 9 on the branch joint 32. According to the moving direction of the catheter 1, the corresponding auxiliary balloon 11 is inflated to expand it, and together with the inflated balloon 2 at the front end, the intestine is supported and blocked, thereby increasing the contact area with the inner wall of the intestine, so that feces and blood in the intestine can be removed stably and quickly.

[0040] Example 3

[0041] like Figure 5 The disposable intestinal cleaning balloon shown comprises a catheter 1, a tip inflatable balloon 2 and a tail connection part 3, wherein the tip inflatable balloon 2 is located on the outside of one end of the tip of the catheter 1, the catheter 1 is a hollow pipe, an airway 4 for supplying air to the tip inflatable balloon 2 is arranged inside the catheter 1, the tail connection part 3 is fixed to one end of the catheter 1 away from the tip inflatable balloon 2, a through hole 5 communicating with the catheter 1 is arranged at the center of the tail connection part 3, the tail connection part 3 comprises a main joint 31 and a branch joint 32 integrally formed and located on the side of the main joint 31, the branch joint 32 is communicated with the airway 4, a vent hole 6 is opened on the surface of the catheter 1, the vent hole 6 connects the airway 4 with the tip inflatable balloon 2, and a guide wire 7 is inserted inside the through hole 5;

[0042] The inflatable balloon 2 at the tip end includes inextensible portions 21 at both ends and an extensible portion 22 in the middle. The inextensible portion 21 is connected to the catheter 1 and can be folded. The cross section of the extensible portion 22 is "V"-shaped.

[0043] By limiting the structure of the inflatable balloon 2 at the tip, the good ductility of the expandable part 22 in the middle can be used to make the balloon quickly deflect and enlarge. At the same time, the inextensible parts 21 at both ends provide the balloon with sufficient strength to prevent the balloon from being squeezed and deformed. The "V"-shaped expandable part 22 is convenient for folding and storage.

[0044] During specific use, the enteroscopic forceps channel 13 is first inserted into the intestine, and then the catheter 1 with the guide wire 7 is inserted into the enteroscopic forceps channel 13. At the same time, the guide wire 7 is clamped by the limit clamp 12. With the support of the guide wire 7, the catheter 1 can smoothly pass through the enteroscopic forceps channel 13, and then the inflation balloon 2 at the front end is inflated through the branch joint 32 by an air pump. The gas quickly expands the inflation balloon 2 at the front end through the airway 4 and the vent 6 to support and block the intestine. Then the catheter 1 is pulled out, and the stool and blood in the intestine are cleaned by the inflation balloon 2 at the front end.

[0045] 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.
