[0002] Anorectal manometry is an examination method that uses a pressure measuring device inserted into the rectum to cause the anus to contract and relax, and to check the function and coordination of the internal and external sphincters, pelvic floor, and rectum. It helps to distinguish the type of outlet constipation. In the resting state, about 80% of the anal canal pressure is formed by the tension and contraction of the internal sphincter, and the remaining 20% ​​is composed of the tension and contraction of the external sphincter. When the anal sphincter is actively contracted, the anal canal pressure increases significantly, and the pressure generated is mainly formed by the contraction of the external sphincter.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] The utility model discloses a rectal pressure measuring tube, such as Figure 1 As shown, it includes a catheter 1, a balloon 2 is fixedly installed at one end of the catheter 1, and a transfer tube 3 is provided at the other end of the catheter 1. The catheter 1 is provided with a branch tube 4 at one end of the transfer tube 3. The outer surface of the catheter 1 is provided with a limit frame 5. The limit frame 5 can effectively prevent the pressure measuring tube from moving during the pressure measurement process. The limit frame 5 includes a limit block 506.

[0024] like Figure 2 As shown, movable grooves 501 are provided on both sides of the limit block 506, and rotating shafts 502 are fixedly installed inside the two movable grooves 501. Movable rods 503 are movably installed on the outer surfaces of the two rotating shafts 502, and the movable rods 503 can rotate.

[0025] A support plate 504 is fixedly mounted on one end of the two movable rods 503 , and an adjustment hole 505 is provided on one side of the limit block 506 .

[0026] like Figure 3 As shown, the support plate 504 includes a fitting plate 5043, and the top surface of the fitting plate 5043 is provided with an adhesive sheet 5044, and the adhesive sheet 5044 can fit the patient's buttocks.

[0027] An inserting strip 5042 is fixedly mounted on the bottom surface of the bonding plate 5043 , a fixing block 5045 is fixedly mounted on one side of the inserting strip 5042 , and limiting holes 5046 are provided on both sides of the fixing block 5045 .

[0028] A slot 5041 is provided on one side of the support plate 504 . The size of the inserting strip 5042 is the same as that of the slot 5041 , and the inserting strip 5042 can be inserted into the slot 5041 , so as to facilitate the disassembly and installation of the bonding plate 5043 , and to facilitate the replacement of the bonding plate 5043 .

[0029] Two fixing sleeves 5047 are provided on one side of the support plate 504, and springs 5048 are fixedly installed inside the two fixing sleeves 5047. One end of the two springs 5048 is fixedly installed with a limiting rod 5049. The limiting rod 5049 can move inside the fixing sleeve 5047. When the limiting rod 5049 moves, it can squeeze the spring 5048.

[0030] A pull rod 5050 is fixedly installed on one side of the two limit rods 5049. When the medical staff pulls the pull rod 5050, the limit rod 5049 can be driven to squeeze the spring 5048. When the insertion strip 5042 is inserted into the slot 5041, the pull rod 5050 can be released. Under the action of the spring 5048, the limit rod 5049 can be inserted into the limit hole 5046 to prevent the insertion strip 5042 from falling.

[0031] like Figure 4-5 As shown, two fixing bars 101 are fixedly installed on the outer surface of the catheter 1. A plurality of fixing holes 102 are provided on one side of the two fixing bars 101. The material of the fixing bars 101 is the same as that of the catheter 1. In the actual production process, the position of the fixing bars 101 can be adjusted.

[0032] A threaded rod 5051 is movably connected to one side of the outer surface of the adjustment hole 505, and a fixed ring 5052 is movably connected to one end of the threaded rod 5051. When the medical staff rotates the threaded rod 5051, the fixed ring 5052 can be pushed to rise and fall. Two insertion rods 5053 are fixedly installed on one side of the fixed ring 5052. When the fixed ring 5052 is raised or lowered, the two insertion rods 5053 can be driven to rise and fall.

[0033] It should be noted that the size of the insertion rod 5053 is the same as that of the fixing hole 102 , and when the threaded rod 5051 rotates, the fixing ring 5052 can be driven to rise and fall, so that the insertion rod 5053 is inserted into the fixing hole 102 .

[0034] The working principle of the utility model is as follows: when in use, the staff first connects the pressure measuring tube to the external machine, and then inserts the balloon 2 into the patient's rectum. After the insertion, the two movable rods 503 can be rotated to make the two adhesive sheets 5044 stick to the patient's buttocks. When it is necessary to adjust the length of the catheter 1 inserted into the rectum, the threaded rod 5051 can be rotated to drive the fixing ring 5052 to rise until the two insertion rods 5053 are pulled out from the fixing hole 102, and the length of the catheter 1 inserted into the rectum can be adjusted. After the adjustment, the threaded rod 5051 can be rotated again to push the fixing ring 5052 down, so that the two insertion rods 5053 are inserted into the fixing hole 102, and then when measuring the pressure of the patient, it can effectively prevent the pressure measuring tube from falling off or entering deeper into the rectum when the patient contracts or expands the anus.

[0035] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
