Description

Technical Field

[0001] The utility model belongs to the technical field of medical auxiliary tools, and specifically relates to a laxative device for patients with myasthenia gravis. Background Art

[0002] There are many reasons for difficult defecation, such as dry stool caused by irregular diet, functional gastrointestinal disease, enteritis, etc. Among them, for patients with myasthenia gravis, difficult defecation is also a common complication, which often causes them trouble. In particular, feces are mainly stored in the ampulla of the rectum, which is generally about five to ten centimeters away from the anus, making it difficult to crush it independently using instruments.

[0003] Enema is an anal medication, mainly used to treat intestinal problems such as constipation and difficulty in defecation. It is delivered into the anus through an applicator, and the glycerin it contains can stimulate intestinal nerves and muscles, thereby accelerating intestinal peristalsis, helping to push feces forward, and lubricating the intestines.

[0004] When myasthenia gravis patients use enema to relieve constipation, they need to hold a disposable medication device, squeeze the enema into the anus, and then the patient clamps the anus to keep the drug in the anus for as long as possible. However, it is difficult for myasthenia gravis patients to clamp the anus, and the drug solution easily overflows, thereby failing to ensure the efficacy of the drug. Therefore, we propose a laxative device for myasthenia gravis patients. Utility Model Content

[0005] The purpose of the utility model is to provide a laxative device for myasthenia gravis patients, which can rotate from the inside out to administer the drug, reduce overflow while applying the drug, and improve the convenience of defecation for myasthenia gravis patients.

[0006] The technical solutions adopted in this utility are as follows:

[0007] A laxative device for myasthenia gravis patients, comprising a disposable silicone ball, a needle tube, a curved tube and a syringe arranged in sequence from right to left;

[0008] One side of the disposable silicone ball is concave inwards and the concave part is sleeved with one end of the needle tube. A drug delivery hole connected with the needle tube is opened on the disposable silicone ball. The liquid outlet of the curved tube is fixedly connected to the other end of the needle tube. The head of the syringe is plugged with the liquid inlet of the curved tube. A rotatable plastic sleeve is sleeved on the outside of the needle tube along the axial direction. When defecating, a sufficient amount of enema is sucked with a syringe, and then it is tightly inserted with the curved tube. The disposable silicone ball is taken out of the sealed bag and tightly sleeved on the needle tube. The plastic sleeve can be held by one hand, and the disposable silicone ball is inserted into the anus to cooperate with the needle tube. , until it is against the dry stool, and with the other hand, rotate the syringe in one direction around the plastic sleeve and push the handle of the syringe to send the suppository inside the syringe along the curved tube and the needle tube to the drug delivery hole of the disposable silicone ball, so that the disposable silicone ball rotates and sprays out the suppository. At the same time, slowly pull out the needle tube with both hands, and the drug can be rotated from the inside to the outside. The disposable silicone ball can limit the external position of the rectum relative to the suppository, and apply it evenly while reducing overflow, which is convenient for improving the convenience of defecation for patients with myasthenia gravis, and finally withdraw the entire device from the anus.

[0009] The recessed part of the disposable silicone ball is integrally connected with a disposable rubber sleeve in a tubular shape. The disposable rubber sleeve is sleeved on the outside of the needle tube and has an interference fit with the needle tube. The disposable silicone ball and the disposable rubber sleeve are sleeved on the outside of the needle tube together to form a soft silicone outer sheath layer to prevent the needle tube from scratching and causing rectal discomfort.

[0010] A plurality of silicone airbags are distributed axially at intervals outside the needle tube, and the silicone airbags are fixedly connected to the disposable rubber sleeve. The soft silicone outer sheath layer serves as the airbag layer, which can be deformed by the contraction and compression of the rectum, so as to adapt to the complex environment in the rectum and further prevent the plug from overflowing.

[0011] A coaxial retaining ring is fixed on the outside of the plastic sleeve. The retaining ring has an arc on one side close to the disposable silicone ball, which is limited outside the anus to prevent the plastic sleeve from being completely immersed in the rectum, so as to leave enough length for hand-holding.

[0012] The liquid inlet of the curved tube is in a barrel mouth structure, and a sealing rubber ring which is interference fit with the syringe is fixed inside the barrel mouth structure, thereby improving the sealing between the curved tube and the syringe and reducing the occurrence of overflow at the connection between the two.

[0013] An annular slide rail is fixed to the end face of the plastic sleeve close to the bent tube. The annular slide rail is coaxial with the needle tube. A groove is provided on the bent tube at a position corresponding to the annular slide rail to facilitate the bent tube to rotate along the annular slide rail through the groove.

[0014] The technical effects achieved by this utility model are:

[0022] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0023] like Figure 1-4 As shown, a laxative device for myasthenia gravis patients includes a disposable silicone ball 1, a needle tube 2, a curved tube 3 and a syringe 4 arranged from right to left in sequence. The disposable silicone ball 1 can be made of medical grade silicone, and the needle tube 2, the curved tube 3 and the syringe 4 can be made of medical grade hard plastic.

[0024] Among them, one side of the disposable silicone ball 1 is concave inward and the concave part is sleeved with one end of the needle tube 2. The disposable silicone ball 1 is provided with a drug delivery hole 6 connected with the needle tube 2. The liquid outlet of the curved tube 3 is fixedly connected to the other end of the needle tube 2. The head of the syringe 4 is plugged with the liquid inlet of the curved tube 3. A rotatable plastic sleeve 5 is axially sleeved on the outside of the needle tube 2. The inner side of the plastic sleeve 5 is rotatably connected to the outside of the needle tube 2. The plastic sleeve 5 can be made of medical-grade hard plastic. The enema can be purchased from major pharmacies in bottles or bags. Several disposable silicone balls 1 can be prepared. When defecating, use the syringe 4 to absorb a sufficient amount of enema, and then plug it tightly with the curved tube 3. Take out the disposable silicone ball 1 from the sealed bag, sleeve it tightly on the needle tube 2, and hold the plastic sleeve with one hand. 5. Insert the disposable silicone ball 1 into the anus with the needle tube 2 until it is pressed against the dry stool. With the other hand, rotate the syringe 4 unidirectionally around the plastic sleeve 5 and push the handle of the syringe 4 to send the suppository in the syringe 4 along the curved tube 3 and the needle tube 2 to the drug delivery hole 6 of the disposable silicone ball 1, so that the disposable silicone ball 1 rotates and sprays out the suppository. At the same time, slowly pull out the needle tube 2 with both hands, and the drug can be delivered from the inside out. The disposable silicone ball 1 can limit the external position of the rectum relative to the suppository, and the application can be evenly reduced while reducing overflow, so as to improve the convenience of defecation for patients with myasthenia gravis. Finally, withdraw the entire device from the anus, discard the disposable silicone ball 1, and clean and disinfect the remaining part.

[0025] Among them, the drug delivery hole 6 on the disposable silicone ball 1 has rounded corners, which does not produce obvious scratching feeling. The diameter of the disposable silicone ball 1 is larger than the diameter of the needle tube 2, so the inner diameter of the needle tube 2 is smaller, and the residual enema inside it is less, and no obvious waste is generated; the disposable silicone ball 1 is simple to obtain, low in cost, and round as a whole. The obstruction feeling when inserted into the rectum is not obvious. It does not need to be disinfected after use, and the remaining part of the laxative device can be cleaned and disinfected for multiple uses to reduce waste.

[0026] like Figure 1 and Figure 3 As shown, the concave part of the disposable silicone ball 1 is integrally connected with a tubular disposable rubber sleeve 7. The disposable rubber sleeve 7 can be made of medical grade silicone material. The disposable rubber sleeve 7 is sleeved on the outside of the needle tube 2 and has an interference fit with the needle tube 2. The disposable silicone ball 1 and the disposable rubber sleeve 7 are sleeved on the outside of the needle tube 2 together to form a soft silicone outer sheath layer to prevent the needle tube 2 from scratching and causing rectal discomfort.

[0027] like Figure 1 and Figure 3 As shown, a number of silicone airbags 8 are distributed along the axial direction at intervals on the outside of the needle tube 2. The silicone airbags 8 can be made of medical grade silicone material. The inner side of the silicone airbag 8 is fixedly connected to the outer side of the disposable rubber sleeve 7. The airbag layer can be deformed by the contraction and compression of the rectum to improve comfort and further prevent the overflow of the plug dew.

[0028] like Figure 1 and Figure 4 As shown, a coaxial retaining ring 9 is fixed on the outside of the plastic sleeve 5, and the inner side of the retaining ring 9 is fixedly connected to the outside of the plastic sleeve 5. The retaining ring 9 can be made of medical grade silicone material. The retaining ring 9 has an arc on the side close to the disposable silicone ball 1, which is limited outside the anus to prevent the plastic sleeve 5 from being completely immersed in the rectum, so as to leave enough length for handholding.

[0029] like Figure 1 and Figure 2 As shown, the liquid inlet of the curved tube 3 is a barrel-mouth structure and a sealing rubber ring 10 is fixed inside the barrel-mouth structure to have an interference fit with the syringe 4. The sealing rubber ring 10 can be made of medical-grade silicone material to improve the sealing between the curved tube 3 and the syringe 4 and reduce the occurrence of overflow at the connection between the two.

[0030] like Figure 1 and Figure 4 As shown, an annular slide rail 11 is fixed to the end face of the plastic sleeve 5 close to the curved tube 3, and a groove is provided on the curved tube 3 at a position corresponding to the annular slide rail 11, so that the curved tube 3 can rotate along the annular slide rail 11 through the groove. The annular slide rail 11 and the needle tube 2 are coaxial.

[0031] The working principle of the utility model is as follows: a plurality of disposable silicone balls 1 can be prepared. When defecation is needed, a sufficient amount of enema is sucked with a syringe 4, and then the syringe is tightly inserted with a curved tube 3. The disposable silicone ball 1 is taken out from the sealed bag, and the disposable rubber sleeve 7 of the disposable silicone ball 1 is tightly put on the needle tube 2. The plastic sleeve 5 can be held in one hand, and the disposable silicone ball 1 is inserted into the anus in cooperation with the needle tube 2 until it presses against the dry stool.

[0032] The other hand rotates the syringe 4 unidirectionally around the plastic sleeve 5 and pushes the handle of the syringe 4 to deliver the enema inside the syringe 4 along the curved tube 3 and the needle tube 2 to the dosing hole 6 of the disposable silicone ball 1, so that the disposable silicone ball 1 rotates and sprays out the enema.

[0033] At the same time, the needle tube 2 is slowly pulled out with both hands, and the drug can be rotated from the inside to the outside. The disposable silicone ball 1 can limit the outer position of the rectum relative to the suppository, and the application can be evenly applied while reducing overflow, which is convenient for improving the convenience of defecation for patients with myasthenia gravis.

[0034] Finally, the entire device is withdrawn from the anus, the disposable silicone ball 1 is discarded, and the remaining part is cleaned and disinfected.

[0035] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
