Detailed Description

In order to make the present invention more clear, the following description of a four-chamber rectal catheter according to the present invention is further described with reference to the accompanying drawings, and the specific embodiments described herein are only used for explaining the present invention, and are not used for limiting the present invention.

As shown in fig. 1 and 2, the four-cavity rectal catheter comprises a catheter 1 made of medical-grade soft silica gel, a hemispherical guide head 6 is integrally connected to the end of the catheter 1, a drainage hole 61 and a second medicine injection port 51 are formed in the guide head 6, and the drainage hole 61 is communicated with the catheter 1.

The outer wall of the front neck of the guide pipe 1 is sleeved with a bag pipe 21 which can generate large elastic deformation, two ends of the bag pipe 21 are respectively and fixedly bonded with the outer wall of the guide pipe 1 in a sealing way, and a gap is left between the inner wall of the middle part of the bag pipe 21 and the outer wall of the corresponding guide pipe 1 to form a sealed cavity 22. The balloon tube 21 and the outer wall of the corresponding catheter 1 together form a balloon 2.

The rear part of the catheter 1 is provided with a first medicine injection nozzle 3, an inflation nozzle 4 and a second medicine injection nozzle 5 which are obliquely crossed with the catheter, and a connecting nozzle 7 which is communicated with the catheter 1. The first and second medicine injection nozzles are respectively connected with a detachable sealing plug 8, the charging nozzle 4 is provided with a one-way valve 9 which can prevent gas from escaping, the first and second medicine injection nozzles are positioned at the opposite sides of the charging nozzle 4, and the connecting nozzle 7 is used for externally connecting a drainage bag (not shown).

The tube wall of the catheter 1 close to the right end of the sac tube 21 is provided with a first medicine injection port 31 with an outward opening, and the tube wall of the catheter 1 close to the left end of the sac tube 21 is radially and uniformly provided with a group of side drainage holes 11 communicated with the catheter 1. A first medicine injection channel 32, a second medicine injection channel 52 and an inflation channel 41 are axially arranged in the tube wall of the catheter 1, one end of the first medicine injection channel 32 is communicated with the first medicine injection port 31, the other end of the first medicine injection channel is communicated with the first medicine injection nozzle 3, one end of the second medicine injection channel 52 is communicated with the second medicine injection port 51, the other end of the second medicine injection channel is communicated with the second medicine injection nozzle 5, one end of the inflation channel 41 is communicated with the sealed cavity 22, and the other end of the inflation channel is communicated with the inflation nozzle 4. Wherein the apertures of the first and second medicine injection ports are smaller than the apertures of the drainage holes 61 and the side drainage holes 11, and the side drainage holes 11 adopt kidney-shaped holes to facilitate drainage.

Still extrude on the pipe 1 of gasbag 2 rear side and embolia a stationary blade 10 that is used for the sutural, stationary blade 10 is the disc, and it is close to all sides edge equipartition a set of through-hole in order to be used for penetrating the stylolite.

In consideration of the manufacturability of the device in production and manufacture, the first injection nozzle 3, the second injection nozzle 5, the charging nozzle 4 and the connecting nozzle 7 can be made into an integrated piece and then are fixedly connected with the guide pipe 1 in a sealing way.

A group of annular bulges 211 with semicircular sections are arranged on the inner wall of the balloon tube 21 and are used for preventing the balloon tube 21 from being completely adhered to the outer surface of the catheter 1, so that the balloon 2 can be smoothly inflated and uniformly expanded; in addition, the annular protrusion 211 also has the function of a reinforcing rib, and the strength of the body of the bag tube 21 is improved.

The use process of the device is as follows: when the air bag 2 is in an unexpanded state, the device is introduced into the rectum of a patient, the corresponding position is adjusted, the air bag 2 is expanded and forms a fixed wall with the inner wall of the rectum by injecting physiological saline or air from the inflating nozzle 4, and the fixing piece is sewed near the anus to assist the fixation of the rectal catheter.

Because this device all has the injection mouth in gasbag 2 front and back both sides, compare in prior art and only set up the defect of injection mouth in gasbag one side, the doctor only need specifically just can go on upper and lower washing through selecting first or second injection mouth and advance to administer, has avoided changing the relative position of injection mouth through removing the rectum pipe to this selects to wash the demand of dosing or washing the dosing down. The device can reduce the operation procedures of doctors, reduce the operation difficulty of the rectal catheter, and simultaneously avoid the pain and the discomfort brought to patients by moving the rectal catheter.

The above embodiments of the present invention are merely examples for clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And such obvious changes and modifications which fall within the spirit of the invention are deemed to be covered by the present invention.
