Description

Technical Field

[0001] The present invention relates to a catheter, and particularly to a rigid catheter, belonging to the technical field of catheters. Background Art

[0002] Vaginal catheters are a commonly used medical device for treating gynecological problems such as cervical diseases and infertility. There are various types of vaginal catheters, and common ones include silicone vaginal catheters and soft vaginal catheters.

[0003] When in use, the catheter can release drugs through holes opened on the outer wall. However, the number of holes in some catheters is fixed and cannot be adjusted according to requirements, and at the same time, the drug release position cannot be adjusted according to requirements, which is likely to cause waste of drugs during use. Therefore, it is necessary to propose a rigid catheter. Summary of the Invention

[0004] The purpose of the present invention is to solve the disadvantages of a rigid catheter in the prior art, and to propose a rigid catheter.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] Design a rigid catheter, including a base. The upper surface of the base is fixedly connected with a catheter body. A plurality of first discharge holes are equidistantly penetrated through the outer walls on both sides of the catheter body. A block is slidably connected to the inner wall of each of the plurality of first discharge holes. Limiting elastic sheets are fixedly connected to the outer walls on both sides of each of the plurality of blocks. Grooves are penetrated through the inner walls of the plurality of first discharge holes at positions corresponding to the limiting elastic sheets, and one end of each of the plurality of limiting elastic sheets extends into the corresponding groove. Two partition plates are symmetrically and fixedly connected to the inner wall of the catheter body.

[0007] Preferably, a second discharge hole is penetrated through the upper end position of the catheter body. A plurality of auxiliary discharge holes are equidistantly penetrated through the outer walls on both sides of the two catheter bodies, and the plurality of auxiliary discharge holes are located in the middle position between the two partition plates.

[0008] Preferably, a plurality of third discharge holes are equidistantly penetrated through the outer sides on both sides of the catheter body below the first discharge holes.

[0009] Preferably, a plurality of positioning holes are penetrated through the upper surface of the base in a cross shape.

[0010] Preferably, the catheter body is inclined relative to the base.

[0011] Preferably, the plurality of limiting elastic sheets are inclined relative to the corresponding blocks.

[0012] A rigid catheter proposed by the present invention has the beneficial effects that when the catheter is inserted into a patient's body and drugs are released through both sides of the partition plate as needed, when the drugs are located in the middle position between the two partition plates, the drugs are released through the second discharge holes and the auxiliary discharge holes to apply drugs to the front, upper and lower sides of the catheter. When the drugs are released through both sides of the partition plate, the drugs are released through the first discharge holes and the third discharge holes to apply drugs to the left and right sides of the catheter. At the same time, according to requirements, the block can be inserted into or removed from the first discharge hole to increase or decrease the number of the first discharge holes. The number of discharge holes can be increased or decreased according to requirements, which increases the flexibility of use, and the partition plate is used to accurately release the drugs to prevent waste of drugs.

[0018] Next, with reference to the drawings of a rigid catheter in an embodiment of the present invention, the technical solutions of a rigid catheter in an embodiment of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Refer to Figures 1-4 , a rigid catheter includes a base 1, the upper surface of the base 1 is fixedly connected with a catheter body 2, a plurality of first discharge holes 3 are equidistantly penetrated through the outer walls on both sides of the catheter body 2, a block 4 is slidably connected to the inner walls of the plurality of first discharge holes 3, limiting elastic pieces 5 are fixedly connected to the outer walls on both sides of the plurality of blocks 4, grooves are penetrated through the inner walls of the plurality of first discharge holes 3 at positions corresponding to the limiting elastic pieces 5, and one ends of the plurality of limiting elastic pieces 5 extend into the corresponding grooves. Two partition plates 6 are symmetrically fixedly connected to the inner wall of the catheter body 2. The catheter body 2 is arranged in a transparent shape. The plurality of limiting elastic pieces 5 are made of PTE.

[0020] Among them, a second discharge hole 7 is formed through the upper end position of the catheter body 2, and a plurality of auxiliary discharge holes 8 are formed through the outer walls on both sides of the two catheter bodies 2 at equal intervals, and the plurality of auxiliary discharge holes 8 are located in the middle position between the two partition plates 6, facilitating discharging through the second discharge hole 7 and the auxiliary discharge holes 8.

[0021] Among them, a plurality of third discharge holes 9 are formed through the outer sides on both sides of the catheter body 2 at equal intervals below the first discharge hole 3, facilitating discharging using the third discharge holes 9.

[0022] Among them, a plurality of positioning holes 10 are formed through the upper surface of the base 1 in a cross shape, facilitating fixing the base 1 and the catheter body 2 using the positioning holes 10.

[0023] Among them, the catheter body 2 is arranged obliquely relative to the base 1 to prevent the liquid medicine from flowing back when the catheter body 2 drains the liquid medicine.

[0024] Among them, the plurality of limiting elastic pieces 5 are arranged obliquely relative to the corresponding stoppers 4, facilitating limiting the stoppers 4 using the limiting elastic pieces 5.

[0025] Working principle: During use, according to the dosage of the medicine, the stopper 4 is removed from the first discharge hole 3, and the first discharge hole 3 on the outer wall of the catheter body 2 is exposed. When the catheter body 2 is inserted into the vagina of the patient, the medicine can be released through the middle position between the two partition plates 6, so that the medicine is discharged only through the second discharge hole 7 and the auxiliary discharge holes 8, or the medicine can be discharged through one side of the partition plate 6, so that the medicine is discharged through the first discharge hole 3 and the third discharge holes 9. When it is necessary to reduce the first discharge hole 3, the stopper 4 is inserted into the first discharge hole 3, and the limiting elastic piece 5 moves into the groove to limit the stopper 4.
