Description

Technical Field

[0001] This utility model belongs to the field of enema tube technology, specifically relating to a retention enema tube device for therapeutic drug administration. Background Technology

[0002] Retention enemas, as a localized targeted drug delivery technique, play an irreplaceable role in the treatment of intestinal diseases. They deliver drug solutions or functional preparations directly to the colorectal lumen through the anus, utilizing the high permeability and absorption capacity of the intestinal mucosa to achieve targeted treatment of the lesion area.

[0003] However, in clinical practice, the amount of medication used for therapeutic administration is much lower than the amount of medication added when administering a non-retention enema. It is often necessary to use non-specialized tools such as syringes or infusion sets to inject the medication. Ordinary enema tube devices are not suitable for this method of administration due to their structure and design, and cannot be directly connected for use, making the medication administration process difficult.

[0004] To address the aforementioned issues, this application proposes a retention enema anal tube device for therapeutic drug administration. Utility Model Content

[0005] This invention provides a retention enema anal tube device for therapeutic drug administration, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a retention enema anal tube device for therapeutic drug administration, comprising an anal tube body and an enema drug administration head and a multi-head connector disposed at both ends of the anal tube body, wherein a fixed connector is connected to one end of the anal tube body via a bracket, and a drug administration mechanism is inserted inside the anal tube body, wherein a branch pipe is connected through one end of the drug administration mechanism and the enema drug administration head; The drug delivery mechanism includes a first tube that is connected to the enema head through a branch pipe. One end of the first tube is fixedly provided with a telescopic tube. A second tube is sleeved on the outside of the telescopic tube. One end of the second tube is fixedly provided with a second insertion sleeve. One end of the telescopic tube is fixedly provided with an annular protrusion. A limiting block is fixedly provided on the top of the annular protrusion. The inner wall of the second tube is provided with a transversely arranged limiting slide and an annular grooves arranged at equal intervals.

[0007] Preferably, the anal tube body includes a tube body and a corrugated telescopic tube fixedly connected to one end of the tube body. One end of the corrugated telescopic tube and one end of the tube body are respectively provided with a first insertion part and a first rotating connection part, and a sealing ring is sleeved on the outside of the first insertion part.

[0008] Preferably, the enema dispensing head includes an outer shell and an enema fluid outlet located on the outside of the outer shell. An annular tube is fixedly provided inside the outer shell, and a dispensing port is provided on the outside of the annular tube. A second rotating connection is fixedly provided at one end of the outer shell, and the second rotating connection is rotatably connected to the first rotating connection via a damping bearing.

[0009] Preferably, the multi-head connector includes a sealing tube, with a first insertion sleeve and an enema fluid inlet at each end of the sealing tube, and a drug delivery branch tube inserted obliquely on the sealing tube, with a third insertion sleeve at one end of the drug delivery branch tube.

[0010] Preferably, the fixed connector includes a connector body fixedly installed inside the anal canal body by a support rod, and the connector body has a second insertion part and a third insertion part at both ends.

[0011] Preferably, the size of the third plug portion matches the size of the third plug sleeve, and the size of the second plug portion matches the size of the second plug sleeve.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting a drug delivery mechanism inside the rectal tube device, not only can enemas be performed, but precise drug delivery can also be achieved. Moreover, the drug delivery mechanism is designed with a slender structure, which can effectively save the amount of drug administered. It is suitable for situations where the amount of drug to be administered at one time is small. It can be directly connected to non-enema devices such as syringes and infusion sets, making drug delivery convenient.

[0013] 2. The detachable connection between the anal tube body and the multi-head connector not only facilitates cleaning and maintenance and long-term use by patients, but also allows for the replacement of different specifications of multi-head connectors as needed. This enables the anal tube body to connect to syringes, infusion sets, or enema bags with large connectors for enema operations involving larger volumes of liquid. By setting a sealing ring on the outside of the first insertion part, the sealing performance after the anal tube body and the multi-head connector are assembled can be improved, preventing enema fluid leakage. By setting a fixed connector, the second and third insertion parts at both ends can be connected to the drug delivery mechanism and the drug delivery branch tube respectively, ultimately enabling a through connection between the drug delivery mechanism and the drug delivery branch tube, facilitating the injection of drugs into the drug delivery mechanism through the drug delivery branch tube.

[0014] 3. The drug delivery mechanism consists of three sections: a first fitting, a telescopic tube, and a second fitting. Its length is adjustable. By installing a corrugated telescopic tube on the main body of the anal tube, not only can the main body of the anal tube be adjusted in length along with the drug delivery mechanism, but the length of the anal tube device can also be adjusted to meet different enema medication needs. Furthermore, the corrugated telescopic tube increases friction with the anus, effectively fixing the anal tube. After the drug delivery mechanism is adjusted, rotating the annular protrusion by a certain angle using the first fitting causes the limiting block on the outer side of the annular protrusion to misalign with the limiting slide. Simultaneously, the limiting block engages in the annular groove. The combination of the limiting block and the annular groove fixes the annular protrusion, thus self-locking the drug delivery mechanism after length adjustment. Conversely, rotating the annular protrusion in the opposite direction using the first fitting resets it. After reset, the limiting block moves out of the annular groove and returns to the limiting slide, allowing for continued left-right sliding within the limiting slide to adjust the length of the drug delivery mechanism, making length adjustment more convenient.

[0015] 4. By setting multiple sets of annular grooves at equal intervals on the inner wall of the second pipe, the limiting block can be fixed by the annular grooves at different positions, and the drug delivery mechanism can be adjusted to different lengths. The drug delivery mechanism can be adjusted in multiple segments, making it more practical. By setting an enema liquid outlet and a drug delivery port on the enema drug delivery head, the enema liquid and the drug liquid can be discharged from the enema liquid outlet and the drug delivery port respectively, which can isolate the enema liquid and the drug liquid and avoid cross-contamination between the enema liquid and the drug liquid.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Examples, such as Figure 1-6 As shown, a retention enema anal tube device for therapeutic drug administration includes an anal tube body 1 and enema drug delivery heads 2 and multi-head connectors 3 disposed at both ends of the anal tube body 1. A fixed connector 4 is connected to one end of the anal tube body 1 through a bracket. A drug delivery mechanism 5 is inserted inside the anal tube body 1. A branch pipe 6 is connected between one end of the drug delivery mechanism 5 and the enema drug delivery head 2. By setting the drug delivery mechanism 5 inside the anal tube device, enema and drug administration can be realized. It is suitable for situations where the single drug dosage is small. It can be directly connected to non-enema devices such as syringes and infusion sets, making drug administration convenient. By setting the drug delivery mechanism 5 as a telescopic structure, the length of the anal tube device can be adjusted to meet different enema drug administration needs. Moreover, after the drug delivery mechanism 5 is telescopically adjusted, it can be self-locked by rotating the enema drug delivery head 2 at a certain angle, making the arbitrary adjustment of the length more convenient. The drug delivery mechanism 5 includes a first fitting 501 that is connected to the enema head 2 via a branch pipe 6. A telescopic tube 503 is fixedly attached to one end of the first fitting 501. A second fitting 502 is sleeved on the outside of the telescopic tube 503. A second insertion sleeve 504 is fixedly attached to one end of the second fitting 502. An annular protrusion 505 is fixedly attached to one end of the telescopic tube 503. A limiting block 506 is fixedly attached to the top of the annular protrusion 505. A transversely arranged limiting slide 507 and equally spaced annular grooves 508 are formed on the inner wall of the second fitting 502. Rotating the telescopic tube 503 via the first fitting 501 causes the limiting block 506 at the top of the annular protrusion 505 to move. After moving into the limiting slide 507, the telescopic tube 503 can slide within the second pipe 502 via the limiting block 506 and the limiting slide 507 to adjust its length. When the limiting block 506 moves to the annular groove 508, the telescopic tube 503 is rotated at a certain angle. At this time, the limiting block 506 and the limiting slide 507 are misaligned. The annular groove 508, in conjunction with the limiting block 506, can fix the telescopic tube 503, preventing it from continuing to slide within the second pipe 502. It can self-lock after length adjustment. Conversely, after rotating the telescopic tube 503 in the opposite direction to reset the limiting block 506, the telescopic tube 503 can continue to be telescopically adjusted.

[0020] The anal tube body 1 includes a tube body 101 and a corrugated telescopic tube 102 fixedly connected to one end of the tube body 101. One end of the corrugated telescopic tube 102 and one end of the tube body 101 are respectively provided with a first insertion part 103 and a first rotating connection part 104. A sealing ring is sleeved on the outside of the first insertion part 103. The anal tube body 1 and the multi-head connector 3 are detachably connected, which is convenient for cleaning and maintenance and convenient for long-term treatment by patients. By setting a sealing ring on the outside of the first insertion part 103, the sealing performance of the anal tube body 1 and the multi-head connector 3 after splicing and assembly can be improved, and leakage of enema fluid can be avoided.

[0021] The enema dispensing head 2 includes an outer shell 201 and an enema fluid outlet 202 located on the outside of the outer shell 201. An annular tube 203 is fixedly installed inside the outer shell 201, and a dispensing port 204 is opened on the outside of the annular tube 203. A second rotating connection part 205 is fixedly installed at one end of the outer shell 201, and the second rotating connection part 205 is rotatably connected to the first rotating connection part 104 through a damping bearing. The rotational connection between the second rotating connection part 205 and the first rotating connection part 104 through the damping bearing allows the enema dispensing head 2 to rotate, thereby facilitating the rotation of the dispensing mechanism 5 for length adjustment. When administering medication, the liquid in the dispensing mechanism 5 is discharged through the dispensing port 204. During enema, the enema fluid flows out from the enema fluid outlet 202, which can be diverted to avoid the enema fluid interfering with the medication and affecting the medication administration.

[0022] Among them, the multi-head connector 3 includes a sealing tube 301, with a first insertion sleeve 302 and an enema fluid inlet 303 respectively at both ends of the sealing tube 301, and a drug administration branch tube 304 is obliquely inserted on the sealing tube 301, with a third insertion sleeve 305 at one end of the drug administration branch tube 304.

[0023] The fixed connector 4 includes a connector body 401 fixed inside the anal tube body 1 by a support rod. The connector body 401 has a second insertion part 402 and a third insertion part 403 at both ends. The fixed connector 4 can connect the drug delivery mechanism 5 and the drug delivery branch tube 304 through the second insertion part 402 and the third insertion part 403 at both ends, so that the drug delivery mechanism 5 and the drug delivery branch tube 304 are connected through each other, which is convenient for assembly. After assembly, the drug can be accurately injected into the drug delivery mechanism 5 through the drug delivery branch tube 304.

[0024] The dimensions of the third insertion part 403 match the dimensions of the third insertion sleeve 305, and the dimensions of the second insertion part 402 match the dimensions of the second insertion sleeve 504. The drug delivery mechanism 5 can be inserted and fixedly installed at one end of the fixed connector 4 through the second insertion sleeve 504 and the second insertion part 402. After the drug delivery mechanism 5 is fixedly installed at one end of the fixed connector 4, the overall length of the drug delivery device can be adjusted by adjusting the length of the drug delivery mechanism 5 as needed.

[0025] During operation, the overall length of the drug delivery device can be indirectly adjusted by adjusting the length of the drug delivery mechanism 5 as needed. After the length adjustment is completed, the drug can be accurately delivered by injecting the drug into the drug delivery mechanism 5 through the drug delivery branch tube 304. Enema can be performed by injecting enema fluid into the device through the enema fluid inlet 303. When delivering the drug, the drug in the drug delivery mechanism 5 is discharged through the drug delivery port 204. When performing an enema, the enema fluid flows out from the enema fluid outlet 202, which can be diverted to avoid the enema fluid interfering with the drug. The corrugated telescopic tube 102 can also increase the friction between the tube and the anus, which can achieve the effect of fixing the anal tube. After the telescopic tube 503 is rotated by the first fitting 501, the limiting block 506 at the top of the annular protrusion 505 moves into the limiting slide 507. The telescopic tube 503 can then slide within the second fitting 502 through the limiting block 506 and the limiting slide 507 to adjust its length. When the limiting block 506 moves to the annular groove 508, the telescopic tube 503 is rotated by a certain angle. At this time, the limiting block 506 and the limiting slide 507 are misaligned. The annular groove 508, in conjunction with the limiting block 506, can fix the telescopic tube 503, preventing it from continuing to slide within the second fitting 502. It can self-lock after length adjustment. Conversely, after rotating the telescopic tube 503 in the opposite direction to reset the limiting block 506, the telescopic tube 503 can continue to be telescopically adjusted. By fixing the limiting block 506 with the annular groove 508 at different positions, the drug delivery mechanism 5 can be adjusted to different lengths, allowing for multi-segment adjustment of the drug delivery mechanism 5, and consequently, multi-segment adjustment of the drug delivery device.
