Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the specific embodiments.

As shown in fig. 1 to 3, a rectal balloon catheter device comprises a catheter 1, a stabilizer 2 and at least one balloon; the interior of the catheter 1 has a fluid passage extending in the axial direction of the catheter 1; any one balloon is arranged on the outer side of the catheter 1 in a sealed state, and is provided with a pressurizing pipeline 3 for supplementing pressurizing media to the corresponding balloon; the stabilizing piece 2 is detachably connected with the guide pipe 1; the fluid channel having a fluid inlet and a fluid outlet; the stabilizer 2 is disposed at one end of the conduit 1 near the fluid outlet.

In this embodiment each balloon has a pressurizing conduit 3, through which the balloon is connected to an external pressurizing means, it being understood that, in order to ensure the inflation effect of the balloon, the illustrated pressurizing conduit 3 has a one-way valve 4, i.e. the pressure can only be supplemented to the balloon by the pressurizing means, and the pressure inside the balloon cannot leak into the pressurizing means.

When in use, the catheter 1 is firstly inserted into the rectum of a patient, and the position of the catheter 1 is fixed through the stabilizing piece 2; at the moment, the doctor opens the pressurizing device to expand the corresponding saccule, so that the compression hemostasis at the position of the saccule is realized.

In this embodiment, the catheter 1 and the balloon are made of transparent materials, such as transparent plastics, so that the hemostatic position can be conveniently judged by a doctor, thereby judging the length of the catheter 1 extending into the rectum. In some embodiments, the outside of the catheter 1 is graduated, thereby also allowing the physician to better record the bleeding site.

In addition, in this embodiment, the pressurizing medium supplied to the balloon by the pressurizing device may be liquid or gas. Generally, the liquid is physiological saline, and the gas is generally air.

For better use of the present embodiment, the stabilizer 2 includes a locking portion 21 and an engaging portion 22; the clamping part 21 is detachably connected with the catheter 1; the attaching portion 22 is integrally formed with the card portion 21.

In this embodiment, the fitting portion 22 is shaped like a hip, so that when the fitting portion 22 contacts with the hip, the position of the catheter 1 can be better fixed, and the hemostatic effect is prevented from being affected by the fact that the balloon can still move in the rectum after being inflated.

For better use of this embodiment, the guide tube 1 has at least one annular groove 5, and the latching portion 21 latches with the guide tube 1 in one of the annular grooves 5.

Since the hemostasis position needs to be judged by a doctor, after the doctor determines the hemostasis position, the clamping part 21 is clamped into the corresponding annular groove 5, and therefore the position can be fixed through the stabilizing part 2 at any bleeding position of the rectum.

To better use the present embodiment, the plurality of balloons includes a first balloon 6, a second balloon 7, and a third balloon 8; the first balloon 6, the second balloon 7 and the third balloon 8 are sequentially arranged outside the catheter 1.

In this embodiment, the first balloon 6, the second balloon 7 and the third balloon 8 are respectively provided with independent pressurizing pipelines 3, and the pressurizing pipelines 3 are communicated with the cavity channels of the balloons and arranged in the fluid channels. Thus, the physician can determine which balloon to inflate based on the specific bleeding location. It is understood that in other embodiments, the number of balloons may also be 1, 2, or 4, 5, etc.

For better use of this embodiment, the first balloon 6 and the second balloon 7 are large balloons and the third balloon 8 is a small balloon; the third balloon 8 is located at the end of the catheter 1 near the fluid outlet.

In the present embodiment, the first balloon 6 and the second balloon 7 are used for deep-rectal compression hemostasis, and the third balloon 8 is used for near-anal compression hemostasis in the rectum and/or primary fixation of the position of the catheter 1.

Therefore, in specific use, the third balloon 8 is firstly inflated to be expanded, and then the catheter 1 is preliminarily fixed in the rectum at the position close to the anus. Then, a doctor visually judges the bleeding position through the saccule and the catheter 1 which are made of transparent materials, and after the hemostasis position is determined, the first saccule 6 or the second saccule 7 is inflated to realize the compression hemostasis at the corresponding position. Furthermore, if necessary, the judgment of the bleeding point in the intestine still needs to be assisted by an endoscope.

Of course, in the use of other embodiments, after the catheter 1 is placed in the rectum, the third balloon 8 can be inflated to realize effective fixation in the rectum near the anus; and then selecting one of the first balloon 6 or the second balloon 7 to inflate and expand, judging the hemostasis effect, and if the hemostasis is not effective, selecting the other balloon to inflate and expand, thereby realizing the compression hemostasis operation.

For better use of this embodiment, a pressure sensor is provided in either balloon.

After the air is supplied to the sacculus, the pressure sensor can feed back the pressure in the sacculus to a doctor, so that the doctor can judge whether the compression is in place or not through the reading of the pressure value, and can know the maximum pressure value of the rectum of the patient, thereby being more beneficial to the doctor to use the embodiment and achieving the hemostatic effect.

For better use of this embodiment, the end of the catheter 1 away from the stabilizer 2 is of a hemispherical head structure.

The hemispherical head structure is located at the fluid inlet, which is the site that enters the rectum first, contacting the rectum with a smooth section, thus avoiding damage to the intestinal wall when the catheter 1 is moved within the rectum.

For a better use of the present embodiment, the end of the catheter 1 remote from the stabilizer 2 is provided with at least one side hole 9, any one of the side holes 9 being in communication with the fluid passage.

In this embodiment, the catheter 1 has a plurality of side holes 9, and the side holes 9 are arranged in opposite order at a proper interval, so that when the flow rate of the exsufflation and defecation is large, the exsufflation and defecation pressure reduction of the patient can be better assisted.

As shown in fig. 4, for better use of the present embodiment, an extension tube 10 is further included; the extension pipe 10 is detachably connected with one end part of the guide pipe 1 close to the stabilizing member 2, and the extension pipe 10 is communicated with the fluid passage. In addition, as shown in fig. 5, in the present embodiment, a sealing cover 11 is further included; the sealing cover 11 is detachably connected with one end part of the guide pipe 1 close to the stabilizing piece 2.

In this embodiment, the catheter 1 device has both an extension tube 10 and a sealing cap 11. The extension pipe 10 and the sealing cover 11 can be detachably connected with the guide pipe 1 in a threaded connection mode. The extension tube 10 is typically used with a drainage bag 12 to facilitate patient mobility. Leakage of defecation can be avoided when the sealing cover 11 is used.

Therefore, the patient can use the extension tube 10 or the sealing cover 11 under different scenes, so that the patient can ensure the hospitalizing quality and avoid the injury from respecting the heart in the hospitalizing process.

The present invention is not limited to the above-mentioned optional embodiments, and any other products in various forms can be obtained by anyone under the teaching of the present invention, and any changes in the shape or structure thereof, all falling within the technical solution of the present invention, all fall within the protection scope of the present invention.
