[0002] Chloral hydrate has sedative, hypnotic, and anticonvulsant effects, with a rapid onset and long duration of action. Its pharmacological action involves inhibiting the ascending activating system of the brainstem reticular formation, inducing a near-physiological sleep. It is widely used as an adjunct medication and treatment for uncooperative children during examinations and treatments, and is one of the commonly used sedatives in pediatrics. Chloral hydrate can be administered orally or rectally. Domestic literature reports that sedation success rates are higher with rectal administration than with oral administration in children.
[0003] Currently, the clinical use of chloral hydrate for rectal administration, i.e., enema, involves several steps: drawing the required amount of chloral hydrate with a syringe; preparing the necessary supplies, such as a disposable rectal tube, disposable gloves, and rectal tube lubricant; connecting the rectal tube to the syringe, lubricating the tip of the rectal tube, and beginning the enema procedure. This process is cumbersome, requires numerous items, and involves complex and error-prone procedures for operators. It is also difficult to control the dosage, and the use of a syringe for drawing the chloral hydrate carries the risk of needlestick injury due to improper procedures.
[0004] How to provide a chloral hydrate enema device that is easy to operate and delivers accurate medication is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0030] Please see Figure 1-4 This embodiment provides a chloral hydrate enema device, including an enema assembly 1, which includes an anal tube 11 with size scale lines marked on it and a side hole 12 on the side of the head of the anal tube 11; and a syringe assembly 2, which includes an injection cylinder 21 and a piston shaft 22. The injection cylinder 21 is used to store chloral hydrate, and the head of the piston shaft 22 is provided with a rubber piston 23 that fits into the injection cylinder 21. The piston shaft 22 is sleeved in the injection cylinder 21, and the head of the injection cylinder 21 is provided with an injection nipple 24. The tail of the anal tube 11 is connected to the injection nipple 24, and the injection cylinder 21 is marked with a capacity scale line.
[0031] Specifically, the enema assembly 1 performs an enema on the patient. The rectal tube 11 is inserted into the intestine, and the size scale on the rectal tube 11 ensures accurate insertion depth. The scale on the syringe 21 ensures accurate chloral hydrate input. Medical staff control the insertion depth according to the scale. The side hole 12 at the head of the rectal tube 11 is used for drug injection, reducing discomfort during the operation. The syringe assembly 2 stores and pushes chloral hydrate. The syringe 21 is used to store chloral hydrate, and the rubber piston 23 completes the sealed storage of chloral hydrate. When in use, the piston shaft 22 pushes the rubber piston 23 to push the chloral hydrate, which is then pushed into the rectal tube 11 through the injection nipple 24 to complete the enema. This device is simple to operate, is a disposable item, and the syringe 21 stores chloral hydrate, which medical staff can use directly. It is disposable after one use to avoid cross-infection. It has fewer accessories, simplifies the operation steps, and improves the enema efficiency of medical staff.
[0032] In some possible implementations, the piston shaft 22 has a cross-shaped cross section, and the tail of the injection cylinder 21 is provided with a snap-fit assembly 3 that is adapted to the opening of the injection cylinder 21. The snap-fit assembly 3 includes a male snap-fit 31 and a female snap-fit 32. The male snap-fit 31 and the female snap-fit are detachably connected. After the male snap-fit 31 and the female snap-fit 32 are connected, a groove is formed that fits into the cross-shaped cross section of the piston shaft 22.
[0033] Specifically, the cross-shaped piston shaft 22 is lighter and avoids material waste. The snap-fit assembly 3 further seals the hydrated chloral in the injection cylinder 21 and limits the piston shaft 22 to prevent accidental contact that could cause the piston shaft 22 to move and push out the hydrated chloral, resulting in waste. The cross-shaped groove formed by the connection of the male snap-fit 31 and the female snap-fit 32 controls the cross-shaped piston shaft 22. When in use, the piston shaft 22 can be pushed by disassembling the male snap-fit 31 and the female snap-fit 32.
[0034] In some possible implementations, the male snap fastener 31 and the female snap fastener 32 are connected by snap-fit.
[0035] In some possible implementations, after the male buckle 31 and the female buckle 32 are connected, buckle ribs 33 are provided on opposite sides.
[0036] Specifically, the interlocking between the male buckle 31 and the female buckle 32 makes disassembly and installation easier, and is simpler to use. When disassembling, medical staff can manually pull the buckle 33 on both sides of the male buckle 31 and the female buckle 32 to complete the disassembly, further increasing its convenience.
[0037] In some possible implementations, a latex sleeve 4 is fitted at the connection between the anal canal 11 and the injection nipple 24.
[0038] Specifically, the latex sleeve 4 further wraps the connection between the anal canal 11 and the injection nipple 24 to prevent chloral hydrate leakage, and further connects and fixes the anal canal 11 and the injection nipple 24 to increase their stability.
[0039] In some possible implementations, the anal canal 11 is 9 cm long, and the size scale lines are marked starting from the head of the anal canal 11, with a total of 8 cm marked, and the smallest scale is accurate to 1 cm.
[0040] Specifically, for chloral hydrate enema injection in children, a rectal tube 11 of 5-7cm or 8cm in length is generally required. This meets the needs without making the device too bulky due to the excessive length of the rectal tube 11, which would also lead to material waste and excessive efficiency. The minimum scale accuracy of 1cm is sufficient to meet the needs of medical staff.
[0041] In some possible implementations, the volume of the injection cartridge 21 is 20 ml, and the volume scale is marked starting from the head of the injection cartridge 21, with the smallest scale accurate to 0.5 ml.
[0042] Specifically, a 15ml enema injection of chloral hydrate for children is generally required. The 20ml empty injection cylinder 21 provides a certain amount of redundancy, meeting daily needs while increasing the space for special situations. The small size of the 20ml empty injection cylinder 21 increases the convenience of the device and avoids waste of materials and excessive space.
[0043] In some possible implementations, the anal canal 11 is made of medical-grade silicone material.
[0044] In some possible implementations, the head of the anal canal 11 is provided with a hemispherical silicone head.
[0045] Specifically, such as Figure 2The anal canal 11 is made of medical-grade silicone, which has excellent temperature resistance and biocompatibility. It does not irritate the skin and intestinal mucosa of young patients, has good softness, can be folded, has low cost, is highly practical, is not prone to rejection reactions, does not cause any harm to the human body, has good biological adaptability, and does not stick to the capillaries of the human body.
[0046] In some possible implementations, there are two side holes 12, which are formed on opposite sides of the head of the anal canal 11.
[0047] Specifically, the two side holes 12 increase the injection rate of chloral hydrate, improve the flow rate, and accelerate the enema speed.
[0048] Finally, it should be noted that the above embodiments are merely specific implementations of this utility model, used to illustrate the technical solution of this utility model, and not to limit it.
