Description

anti-infection enema

technical field

The invention relates to the technical field of medical equipment, in particular to an anti-infection enema.

Background technique

The enema method mentioned in medicine is to use the anal canal to insert liquid into the colon from the anus through the rectum, so as to achieve the therapeutic effect of laxative, bowel cleansing, exhaust and detoxification. The liquid can stimulate intestinal peristalsis, soften and remove feces, and have the effects of cooling, inducing labor, diluting intestinal toxins, and reducing absorption. In addition, the liquid can also achieve therapeutic effects such as supplying drugs, nutrients, and water through dissolved drugs. The purpose of using the enema method is to: relieve constipation; cool down; prepare for certain operations, examinations or childbirth; dilute and remove harmful substances in the intestinal tract to reduce poisoning.

In order to prevent anal leakage during enema, the existing enema device is usually provided with an air bag on the outer wall of the anal canal and an air inlet pipe connected to the air bag in the tube wall. The air bag on its outer wall is passed into the patient's anus together, and then inflated through the air intake device connected with the air intake pipe to inflate the air bag to inflate the air bag, thereby realizing the sealing of the patient's anus, preventing the cleaning fluid in the anus from leaking out, and finally Inject cleaning solution into the patient's anus through the enema cylinder, liquid inlet tube and anal canal.

However, the air bag used by the existing enema device to block the anus is usually fixedly installed on the anal canal, that is, the distance between the front end of the anal canal and the air bag is fixed. Therefore, during enema, the anal canal part in front of the air bag All must be inserted into the patient's anus, and because different patients have different constitutions or different conditions, the length of the anal canal that needs to be inserted also depends on the situation. Therefore, when using the existing enema device for enema, the insertion length may be too long. Long lead to hard damage to the patient, and the insertion length may be insufficient, which cannot achieve the best effect.

Moreover, the blocking air bag on the existing enema needs to be connected with an inflatable device, resulting in a complex structure and troublesome operation. After the sealing air bag is inflated to block the anus, the air leakage of the sealing air bag often shrinks and causes the anus In the case of leakage of dirt, cross-contamination is likely to occur.

The anti-infection enema device of the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in Figures 1 and 2, the anti-infection enema device according to the embodiment of the present invention includes an anal canal 10 for inserting into the patient's anus, an enema cylinder 40 for containing enema cleaning liquid, and an enema cylinder 40 connected with the enema cylinder 40 respectively. An infusion tube 50 connected to the rear end of the anal canal 10 , wherein the anal canal 10 and the infusion tube 50 are detachably connected in a sealed manner, and the anal canal 10 is sleeved with an expansion member 20 and a compression nut 30 .

Specifically, the outer wall of the rear end of the anal canal 10 is provided with an external thread 11, and the anal canal 10 is provided with a blocking member 12 in front of the external thread 11; the expansion member 20 is sleeved on the anal canal 10 On the rear end, it includes a first end 21, a second end 22 and an expansion and contraction body 23 connected between the first end 21 and the second end 22, and the first end 21 is formed by The stopper 12 is used for limit blocking; the compression nut 30 is threaded on the external thread 11 of the anal canal 10 and pressed against the second end 22 to adjust the second The distance between the end portion 22 relative to the first end portion 21; when the compression nut 30 moves toward the blocking member 12, the second end portion 22 is driven to approach the first end portion 21 so that The expansion-contraction body 23 expands radially.

According to the anti-infection enema device of this embodiment, before use, the compression nut 30 is adjusted to a relatively rear position, so that the distance between the compression nut 30 and the blocking member 12 is greater than or equal to that of the expansion member 20 without force. Axial length in the state of natural extension, when the diameter of the central part of the expansion-contraction body 23 is in the minimum state, so that it can be inserted into the patient's anus; To make it move forward relative to the anal canal 10, so that the expansion-contraction body 23 is axially compressed and at the same time radially expanded, that is, the diameter of the middle part of the expansion-contraction body 23 is increased, thereby blocking the anus of the patient. This solves the problem that the existing enema device needs to inflate the balloon, the adjustment is simple, quick and convenient, and the enema efficiency is improved.

As a preferred embodiment of the present invention, the expansion and contraction body 23 is an oval structure with a central through hole. In this way, it can easily enter the patient's anus when it is not under axial pressure; and when it is squeezed by the compression nut 30, it can be axially compressed and radially expanded into a spherical structure, so as to treat the patient's anus blockage. Further, the expansion-contraction body 23 is a hollow sealed air bag filled with gas made of rubber material. Of course, it can also be made into a solid oval structure with a central through hole, as long as the compression nut 30 is used to compress the axially to realize the expanded structure.

In an embodiment of the present invention, a connecting piece 13 is provided between the compression nut 30 and the second end portion 22 . Specifically, the function of the connectable part 13 is to block between the compression nut 30 and the second end 22, so that the compression nut 30 has a certain distance relative to the second end 22, so that when the expansion part 20 enters the patient When it is in the anus, the hands of the medical staff will not be too close to the patient's anus when adjusting the compression nut 30, so as to facilitate the adjustment of the compression nut 30.

Wherein, a first washer 14 is provided at an end of the connecting member 13 opposite to the compression nut 30 . Utilizing the effect of the modified first washer 14, the compression nut 30 will not drive the connecting piece 13 or the expansion piece 20 to rotate during the rotation adjustment.

In some embodiments of the present invention, the blocking member 12 is a conical structure, and its diameter is gradually reduced from the back to the front. In this way, the blocking member 12 can be easily inserted into the anus of the patient, and at the same time, it can expand the anus to a certain extent so that the expansion member 20 behind the blocking member 12 can enter.

Further, the blocking member 12 is provided separately from the anal canal 10 , and the blocking member 12 is threaded on the external thread 11 of the anal canal 10 . Thereby adjusting the position of the blocking member 12 on the anal canal 10, the distance between the expansion member 20 and the front end of the anal canal 10 can be adjusted, that is to say, before the anal canal 10 is inserted into the patient’s body, the blocking member can be adjusted according to the patient’s condition 12 to adjust the distance between the expansion member 20 and the front end of the anal canal 10, that is, to adjust the insertion length of the anal canal 10.

Furthermore, a second gasket 15 is disposed between the blocking member 12 and the first end portion 21 . Utilizing the function of the modified second washer 15, the blocking member 12 will not drive the expansion member 20 to rotate during rotation adjustment, avoiding the phenomenon that the expansion member 20 is rotated and rubbed against the external thread 11 to cause the expansion and contraction body 23 to break.

The above is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Under the inventive concept of the present invention, the equivalent structural transformation made by using the description of the present invention and the contents of the accompanying drawings, or direct/indirect use All other relevant technical fields are included in the patent protection scope of the present invention.
