[0002] A rectal instillation device is a medical device used to administer drugs to patients through the rectum. It usually consists of a container that can hold liquid medicine and a tube inserted into the rectum. The use of a rectal instillation device can have the following purposes: cleansing enema, rectal drip method, suppository insertion method, etc. Its operation method is mainly to deliver the drug directly into the intestinal tract through the anus.

[0003] In actual use, since each patient's weight, age, gender, health status and drug metabolism ability are different, the required drug dosage will also be different. Different symptoms require different drug dosages to achieve therapeutic effects. For example, mild constipation may only require a small amount of enema solution, while severe constipation may require more liquid. Therefore, when administering the drug, it is necessary to control the dosage of the drug. However, since the integrated rectal irrigation device is a device in which the drug is pre-injected into the irrigation device, when it is used, the staff controls the amount of drug injected according to their experience, that is, after administering the drug for a certain period of time, stop and observe the corresponding capacity scale, and continue to administer the drug when the dosage requirement is not met.

[0023] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with examples. The examples are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0024] Embodiment 1

[0025] according to Figure 1-Figure 5 As shown, this embodiment proposes an integrated rectal perfusion device, including a barrel 1, in which a medicine is pre-loaded. The medicine is used for rectal administration, such as an ultrasonic coupling agent. Therefore, for the integrated rectal perfusion device, it combines the functions of drug storage, transportation and administration, aiming to provide convenient, safe and effective rectal administration. Therefore, in this embodiment, the barrel 1 is pre-loaded with a corresponding medicine.

[0026] A connecting cylinder 2 is installed at the output end of the cylinder 1, and a one-way valve 3 is installed on the connecting cylinder 2. In this embodiment, the one-way valve 3 is manually opened and closed. Under normal circumstances, the one-way valve 3 is in a closed state. At this time, the medicine in the cylinder 1 cannot be discharged normally. When in use, the staff manually opens the one-way valve 3, and the medicine in the cylinder 1 can pass through the connecting cylinder 2 normally.

[0027] An anal canal 4 is installed at one end of the connecting tube 2, and an opening 5 is provided at one end of the anal canal 4. In this embodiment, the anal canal 4 is a hose. When in use, one end of the opening 5 is inserted from the patient's anus. Further, an outward elastic cover 14 is installed on the anal canal 4, one end of the outward elastic cover 14 is fixedly connected to the anal canal 4, and the inner side of the outward elastic cover 14 is connected to the anal canal 4 through an elastic ring 15. The outward elastic cover 14 has elasticity, such as Figure 5As shown, the cross section of the external elastic cover 14 is in a truncated cone state, so one end (left end) of the external elastic cover 14 is in an expanded state, so when it enters the patient's body, the external elastic cover 14 is deformed by force, and the elastic ring 15 is in a concave state when it is stressed, which provides a corresponding resistance force to promote its contact with the patient's body, thereby playing a role in sealing the anus and maintaining the stability of the anal canal 4 after entering. At the same time, the connection between the external elastic cover 14 and the elastic ring 15 is set in an arc shape to avoid the adverse effects of sharp parts on the patient.

[0028] A connecting block 6 is installed on the outer side of the cylinder 1, and the connecting blocks 6 are evenly arranged in several groups. In the present embodiment, two groups of connecting blocks 6 are symmetrically arranged, and an external thread is arranged on the connecting block 6. A quantitative ring 7 is sleeved on the outer side of the cylinder 1, and the quantitative ring 7 is connected to the connecting block 6 through a thread, so that the position of the quantitative ring 7 on the cylinder 1 can be adjusted. Correspondingly, a medicine capacity scale line 19 is provided on the outer side of the cylinder 1, and the medicine capacity scale line 19 is located between the two groups of connecting blocks 6. During use, the specific needs of the patient are different, and the dosage of the drug is also different. Therefore, before administering the drug, the staff can adjust the quantitative ring 7 to a suitable position according to the medicine capacity scale line 19.

[0029] The outer side of the cylinder 1 is also sleeved with a ring 8, and a push-in assembly is installed on the cylinder 1, and the push-in assembly is connected to the ring 8. After the position of the quantitative ring 7 is adjusted, the staff manually presses the push-in assembly and applies thrust. At this time, the one-way valve 3 is in an open state, and the medicine in the cylinder 1 is continuously discharged. When the ring 8 contacts the quantitative ring 7, it stops. At this time, the dosage of the medicine meets the established requirements. The diameter of the inner circle of the corresponding ring 8 can accommodate the connection block 6 to pass through.

[0030] The inner side of the connecting tube 2 is provided with a medicine limiting opening 16, and a connecting cavity 17 is formed between the outer side of the medicine limiting opening 16 and the connecting tube 2. Figure 3 As shown, the output end of the medicine limiting port 16 is located on the inner side of the anal canal 4, a locking piece 18 is installed on the connecting tube 2, and the locking piece 18 is provided with several groups, the locking piece 18 is connected to the connecting tube 2 by a thread, and one end of the locking piece 18 is in contact with the anal canal 4. When in use, one end of the anal canal 4 is directly inserted into the connecting tube 2 (the end of the connecting tube 2 close to the anal canal 4 is connected to the outside world), and when the medicine limiting port 16 enters the anal canal 4, it will cause the anal canal 4 to be deformed, thereby enabling the anal canal 4 to better fit the connecting cavity 17. Accordingly, after the connection, the staff rotates the locking piece 18 by hand. In this embodiment, the locking piece 18 corresponds to a bolt, which is connected to the connecting tube 2 by a thread, so that under the action of the threaded connection, the locking piece 18 can press the anal canal 4.

[0031] The pushing assembly includes a piston 9, which is located on the inner side of the cylinder 1 and can move inside the cylinder 1. The piston 9 is adapted to the cylinder 1. A core rod 10 is installed on the piston 9, and a push block 11 is installed on the core rod 10. An extension portion 12 is provided on the cylinder 1, and a connecting rod 13 is installed on the push block 11. The connecting rod 13 is provided in several groups. The connecting rod 13 passes through the extension portion 12 and is connected to the retaining ring 8. Therefore, during the movement of the push block 11, it drives the retaining ring 8 to move through the connecting rod 13.

[0032] Embodiment 2

[0033] according to Figure 6 and Figure 7 As shown, the difference between this embodiment and embodiment one is that a heating base 20 is provided on the outer side of the cylinder 1, a limit seat 21 is installed on the heating base 20, and the limit seat 21 is connected to the heating base 20 by bolts, an electric heating wire is installed on the inner side of the heating base 20, a digital thermometer 22 is installed on the limit seat 21, the inner sides of the heating base 20 and the limit seat 21 are both arranged in an arc shape, and both are installed with a contact elastic pad 23. In this embodiment, after the heating base 20 and the limit seat 21 are connected, a circular inner cavity is formed on their inner sides, and the front and rear ends of the circular inner cavity are connected to the outside world. Therefore, part of the body of the cylinder 1 can be located in the circular inner cavity, which protects the cylinder 1 through the contact elastic pad 23.

[0034] Then the heating base 20 needs to be electrically connected to the external power supply device, and then the electric heating wire set inside it can be started, so that the barrel 1 is heated by the heating base 20. Because some drugs are more easily absorbed by the human body at a specific temperature, or are more comfortable to use in a warm state, and this device is suitable for rectal drug infusion, but the temperature in the rectum is high, and too cold drugs may cause discomfort. Therefore, the drugs in the barrel 1 can be heated by the set heating base 20, and accordingly, the heated temperature is sensed by the digital thermometer 22 to avoid high temperatures. When using, the temperature of the drug can be tested on the skin to ensure that the internal tissue of the rectum will not be burned.
