Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a cervical medicine applicator. Background Art

[0002] Cervical diseases are common among female patients. For patients with severe symptoms, physical therapies such as liquid laser and electrocautery or surgical therapies are usually required for treatment. After physical treatment or surgery, anti-inflammatory and hemostatic liquid medicine needs to be applied to the diseased area of the cervix.

[0003] Since the cervix is located inside the human body, it is impossible to directly apply the medicine to the diseased area of the cervix. The commonly used method is to use a speculum to open the vagina, and use forceps to insert a medical cotton swab dipped with medicine into the cervix to apply medicine to the diseased area of the cervix. After applying the medicine, a vaginal tampon is inserted to prevent the medical cotton from falling off. After several hours of applying the medicine, when the medicine is fully attached to the diseased area of the cervix, the medical cotton is removed. This method is inconvenient to use. Moreover, using a medical cotton swab for application will also cause some liquid medicine to adhere to the medical cotton and cannot be fully utilized.

[0004] Currently, a cervical medicine applicator such as the one with the publication number CN109395238A is usually used. The medicine outlet head of this device is spherical, but the rubber pressing block of the push rod is disc-shaped. During the process of pushing out the medicine, all the medicine in the medicine outlet head cannot be pushed out all the time. Eventually, there will be medicine remaining in the medicine outlet head that cannot be used, resulting in waste. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a cervical medicine applicator for the above-mentioned existing technical problems, achieving the effect of reducing the residue of medicine in the medicine outlet head and reducing waste.

[0006] In view of this, the utility model provides a cervical medicine applicator, including:

[0007] An outer cylinder, one end of the outer cylinder is open, and the other end is provided with a medicine outlet head, the medicine outlet head is hemispherical, and a plurality of medicine outlet holes are arranged on the medicine outlet head;

[0008] A push rod, the push rod is coaxial with the outer cylinder, one end of the push rod is slidably arranged inside the outer cylinder, and the other end passes through the open end of the outer cylinder and extends to the outside of the outer cylinder. The end of the push rod located inside the outer cylinder is hemispherical and matches the shape of the medicine outlet head.

[0009] In this technical solution, the medicine outlet head of the outer cylinder is inserted into the medicine, the push rod is pulled to suck the medicine into the outer cylinder, and then the outer cylinder is inserted into the cervix, and the push rod is pushed to make the medicine spray out from the medicine outlet holes onto the cervix to complete the medicine application. During the pushing process, the shape of the end of the push rod matches the shape of the medicine outlet head, which can be pushed to the medicine outlet head, and all the medicine in the medicine outlet head can be pushed out, reducing the residue of medicine in the medicine outlet head and reducing waste.

[0010] Further, a blocking member is provided outside the outer cylinder. The blocking member includes a blocking state and a released state. In the blocking state, the blocking member isolates between the medicine outlet head and the vaginal wall. In the released state, there is no barrier between the medicine outlet head and the cervix.

[0011] Further, the blocking member includes:

[0012] A blocking sleeve, one end of the blocking sleeve is open, and the other end is sleeved outside the medicine outlet head. The blocking sleeve is provided with a tearing line along the length direction, and the tearing line divides the blocking sleeve into two identical parts on the left and right;

[0013] An operation section, the operation section is connected to the blocking sleeve, and the other end of the operation section extends to the end of the outer cylinder away from the medicine outlet head. Pulling the operation section can separate the blocking sleeve along the tearing line to expose the medicine outlet head.

[0014] In this technical solution, during the process of the outer cylinder extending into the cervix, although the vagina is opened by a vaginal speculum, the medicine outlet head is also likely to adhere to the mucus in the vagina. When the mucus contacts the powdery medicine in the medicine outlet hole and the outer cylinder, the powder will become wet and block the medicine outlet hole. Even under the pushing force of the push rod, there will still be a blocking situation, which slows down the medicine application speed. And during the process of the outer cylinder extending into the cervix, a small amount of powdery medicine will still fall out from the medicine outlet hole, resulting in a certain waste and inaccurate medicine application dose. During the process of the outer cylinder extending into the vagina, by sleeving the blocking sleeve outside the outer cylinder, the blocking sleeve isolates between the vaginal wall and the outer cylinder, reducing blockage and medicine spillage. Then when the medicine outlet head reaches the medicine application point of the cervix, pulling the operation section makes the blocking sleeve separate along the tearing line to expose the medicine outlet head, so that medicine can be applied. The blocking member can reduce the blockage of the medicine outlet hole, ensure the medicine application efficiency, reduce the waste of medicine spillage, and ensure the accuracy of the medicine application dose.

[0015] Further, the tearing line is in a zigzag shape.

[0016] Further, an outwardly extending hand-held portion is provided at the end of the outer cylinder away from the medicine outlet head. A through hole is opened on the hand-held portion. One end of the operation section away from the blocking sleeve can pass through the through hole. An anti-detachment structure is also provided between the operation section and the hand-held portion, and the anti-detachment structure prevents the operation section from sliding out of the through hole.

[0017] Further, the anti-detachment structure includes a tapered section provided at the end of the hand-held portion. The tapered section has elasticity. The diameter of the largest outer diameter of the tapered section is greater than the diameter of the through hole, and the outer diameter in the middle of the tapered section is equal to the diameter of the through hole.

[0018] In this technical solution, the tapered section is passed through the through hole from the smallest diameter to the largest diameter. The tapered section is squeezed and can completely pass through the through hole, but cannot be withdrawn from the through hole in the reverse direction.

[0019] Further, the whole of the blocking member is made of soft PVC plastic material.

[0020] In this technical solution, the blocking member is made of soft PVC plastic material with the same material as the infusion tube.

[0021] Further, scales are engraved on the outer wall of the outer cylinder.

[0022] In this technical solution, the scales can display the extraction amount of the medicament.

[0023] Further, anti-slip lines are provided on the holding part.

[0024] The beneficial effects of the present utility model are as follows:

[0025] 1. Insert the medicine outlet head of the outer cylinder into the medicament, pull the push rod to suck the medicament into the outer cylinder. Then, insert the outer cylinder into the cervix and push the push rod to make the medicament spray out from the medicine outlet hole onto the cervix to complete the medicine application. During the pushing process, the shape of the end of the push rod matches the shape of the medicine outlet head, so that it can be pushed to the medicine outlet head, and the medicament in the medicine outlet head can be completely pushed out, reducing the residue of the medicament in the medicine outlet head and reducing waste.

[0026] 2. The blocking member can reduce the blockage of the medicine outlet hole, ensure the medicine application efficiency, reduce the waste of the scattered medicament, and ensure the accuracy of the medicine application dose.

[0027] 3. The anti-detachment structure prevents the operation section from slipping out of the through hole. Description of the Drawings
