Description

Technical Field

[0001] This utility model belongs to the field of nursing operation instrument technology, and specifically refers to an electrothermal rectal pressure stimulator. Background Technology

[0002] When patients experience bowel problems for various reasons, rectal massage can provide relief and treatment. Rectal massage is a medical procedure typically performed by a doctor or a professional massage therapist. The procedure involves gentle pressure and massage of the rectal area, designed to help stimulate and relax the intestinal muscles, promote bowel movements, and thus help relieve constipation and facilitate defecation.

[0003] Current technologies primarily utilize digital rectal stimulation to help patients empty their rectum, relieve constipation, or assist patients with neurogenic bowel dysfunction. However, digital anal stimulation can be embarrassing for patients, family members, and caregivers. While convenient and practical, most patients opt for enemas or glycerin suppositories, forcibly stimulating intestinal spasms to induce defecation. However, drug-based stimulation can lead to intestinal nerve disorders, intestinal fatigue, and decreased insensitivity to stimulation. It can also cause abnormal intestinal spasms, resulting in abdominal pain and intestinal bleeding. Currently available electric rectal pressure stimulators rely solely on patient perception for pressure, leading to delayed responses and difficulty in real-time assessment of massage effectiveness. Utility Model Content

[0004] The main purpose of this invention is to provide an electrothermal rectal pressure stimulator, which aims to provide a rectal pressure stimulation device that is easy to operate and has a stable effect. It can replace fingers to improve the success rate of defecation promotion by physical methods in patients with neurogenic rectum, and avoid the adverse effects of relying on drug stimulation.

[0005] To achieve the above objectives, the solution of this utility model is: An electrothermal rectal pressure stimulator includes an instrument body, a pressing rod, springs, and a disposable rubber sleeve. The upper part of the instrument body is formed by a handle and a pair of parallel sliding rods, creating a through hole. The pressing rod has a grip and a pressing part at both ends. The grip is located inside the through hole, with its two ends slidably fitted onto the sliding rods. The pressing part is located outside the sliding rods and is used to press the rectal anal canal wall instead of using fingers. Several springs are provided between the grip and the handle. The disposable rubber sleeve is replaceably fitted onto the surface of the pressing part.

[0006] The instrument body has a mounting cavity; a battery and a heating circuit board electrically connected to the battery are disposed in the mounting cavity, and the heating circuit board is electrically connected to a heating rod disposed in the pressing part.

[0007] Preferably, the temperature of the heating rod is set to 35℃~40℃.

[0008] Preferably, the electrothermal rectal pressure stimulator further includes a temperature display electrically connected to the heating circuit board.

[0009] Preferably, the mounting cavity is further provided with a pressure display electrically connected to the battery, and a pressure sensor is provided between the end of at least one spring and the handle, the pressure sensor being electrically connected to the pressure display.

[0010] The side of the sliding rod is provided with several spherical protrusions, which provide overcoming frictional resistance when sliding at the end of the grip.

[0011] The grip portion is designed with a wavy line shape and has several grooves for the fingers to grip.

[0012] The surface of the pressing part is provided with several articulated balls.

[0013] A corner connection is provided between the pressing part and the gripping part, and the corner connection makes the height of the pressing part lower than that of the gripping part.

[0014] After adopting the above technical solution, the present invention has the following technical effects: This invention utilizes a handle supported in the palm, with the fingers gripping the handle portion. This drives the pressing rod to move along the linear direction of the sliding rod, thereby simulating the pressing action of the fingers. This improves the efficiency of physical methods for promoting defecation in patients with neurogenic rectum, avoiding the adverse effects of relying on drug stimulation. A spring provides elasticity and resistance between the handle and the handle portion, preventing excessive pressure on the rectal and anal canal walls and allowing the pressing rod to return to its original position when the operator releases the grip. A disposable rubber sleeve isolates the pressing rod from fecal contamination, preventing cross-infection. This invention employs manual operation, allowing the operator to receive feedback from both the patient and the spring, making it easier to control the pressure. Attached Figure Description

Detailed Implementation

[0017] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0018] refer to Figure 1 As shown, this utility model discloses an electrothermal rectal pressure stimulator, including an instrument body 1, a pressing rod 2, a spring 3, and a disposable rubber sleeve 4; The upper part of the instrument body 1 is formed by a handle 11 and a pair of parallel sliding rods 12 to form a through hole 13; The pressing rod 2 has a gripping part 21 and a pressing part 22 at its two ends respectively; the gripping part 21 is located inside the through hole 13, and its two ends are slidably sleeved on the sliding rod 12; the pressing part 22 is located outside the sliding rod 12 and is used to press the rectal and anal canal wall instead of the fingers, which stimulates the pressure receptors on the rectal and anal canal mucosa. The stimulation signal is transmitted to the lower spinal cord center and the higher defecation center of the brain to start the defecation process. Several springs 3 are provided between the grip 21 and the handle 11; A disposable rubber sleeve 4 is replaceably fitted onto the surface of the pressing part 22.

[0019] Through the above-described scheme, this utility model allows the pressing rod 2 to move along the linear direction of the sliding rod 12 by supporting the handle 11 in the palm and gripping the handle 21 with the fingers. This drives the pressing part 22 to simulate the pressing action of the fingers, thereby improving the efficiency of defecation promotion for patients with neurogenic rectum through physical methods and avoiding the adverse effects of drug stimulation. The spring 3 provides elasticity as resistance between the handle 11 and the handle 21 to prevent the operator from applying excessive pressure to the rectal and anal canal walls, and allows the pressing rod 2 to return to its original position when the operator stops gripping. The disposable rubber sleeve 4 is used to isolate the pressing rod 2 from fecal contamination and prevent cross-infection. This utility model adopts a manual operation method, and the operator can receive dual feedback from the patient and the spring 3, making it easier to control the force.

[0020] The following are specific embodiments of the present invention.

[0021] The instrument body 1 has a mounting cavity 14; a battery 5 and a heating circuit board 6 electrically connected to the battery 5 are housed within the mounting cavity 14. The heating circuit board 6 is electrically connected to a heating rod 7 disposed within the pressing part 22. By supplying power to the heating rod 7 through the heating circuit board 6, the temperature of the pressing part 22 and its disposable rubber sleeve 4 can be increased to a certain extent, achieving a warm massage effect. In this embodiment, the temperature of the heating rod 7 is set to 35℃~40℃.

[0022] Furthermore, the present invention also includes a temperature display 8 electrically connected to the heating circuit board 6 for indicating the current temperature of the pressing rod 2.

[0023] Meanwhile, a pressure display 9 electrically connected to the battery 5 is also provided in the aforementioned mounting cavity 14. At least one spring 3 has a pressure sensor 10 installed between its end and the handle 11. The pressure sensor 10 is electrically connected to the pressure display 9 so that the pressure display 9 can display the current output pressure (corresponding to the pressure when the operator grips the grip part 21). When multiple springs 3 have pressure sensors 10 installed at their ends, the displayed pressure can be the average value returned by each pressure sensor 10.

[0024] The sliding rod 12 has several spherical protrusions 121 on its side. These protrusions provide overcoming frictional resistance as the end of the grip 21 slides. When the operator grips the grip 21, a slightly larger force is required to move the grip over the protrusions 121 to continue moving. Therefore, the protrusions 121 can be used as a "gear selector" to indicate different preset output pressure levels.

[0025] The aforementioned grip portion 21 is designed with a wavy line shape and has several grooves 211 for the fingers to grip.

[0026] The surface of the pressing part 22 is provided with a plurality of articulated balls 221 to simulate finger joints in order to achieve a more realistic massage effect.

[0027] A corner connecting part 23 is provided between the pressing part 22 and the hand grip part 21, and the corner connecting part 23 makes the height of the pressing part 22 lower than that of the hand grip part 21. This design makes it easier to insert the pressing part 22 into the patient's rectum when the patient is sitting on the commode.

[0028] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
