Detailed Description

The utility model relates to a gynaecology device of dosing, as shown in fig. 1-2, including the expander to and set up in the expander, with expander sliding connection's the device of dosing, the expander will be dosed the device parcel and in inside, avoid dosing device and external contact to make pollutions such as bacterium, germ device of dosing.

The expander comprises a shell 8, a first expanding plate 1 and a second expanding plate 12 which are in sliding connection with the shell 8, wherein the first expanding plate 1 and the second expanding plate 12 move oppositely, the first expanding plate 1 and the second expanding plate 12 are surrounded to form a cylinder, and the shell 8 is square, and a sleeve 13 is fixedly arranged in the middle of the inner lower surface; first expansion board 1, second expansion board 12 and 8 sliding connection's of casing one end lower surface are provided with helical rack 3, helical rack 3 is through setting up first helical gear 4 and the meshing of second helical gear 6 in the 8 intracavity of casing, the axial of second helical gear 6 is unanimous with the direction of dosing, the upper surface fixed connection and coaxial of second helical gear 6 lower surface and knob 7, knob 7 cover is on sleeve 13 and rotate with sleeve 13 and be connected, knob 7's big radius end protrusion in casing 8's surface and with 8 sliding connection of casing. It can be understood that when the medical staff uses the medical staff, the medical staff can manually rotate the rotating knob 7, and the rotating knob 7 rotates to drive the second bevel gear 6 to rotate, so as to drive the first bevel gear 4 meshed with the second bevel gear 6 to rotate; at this time, the two first helical gears 4 symmetrically arranged rotate in opposite directions, and therefore, the two helical racks 3 engaged with the first helical gears 4 also move toward each other, so that the first expansion plate 1 and the second expansion plate 12 are opened or closed. The whole dilator is made of light materials, so that the dilator is convenient for medical staff to use, such as medical grade plastics or light alloys.

The device of dosing is including the centre pushing ram 10 that sets up the through-hole, pushing ram 10 internal surface and the 9 sliding fit of pole of dosing, pushing ram 10 surface and sleeve 13 sliding fit, the length of pushing ram 10 is greater than the whole length of expander, give the length more than or equal to pushing ram 10 of pole 9 of dosing, it is provided with silica gel to serve one of pole 9 of dosing to stretch into pushing ram 10. When medical personnel used, twisted button rotary button 7 earlier for first expansion board 1, second expansion board 12 are opened, promote push rod 10 again, push rod 10 to the disease position that is close to the patient, promote again for medicine pole 9, will give medicine on the pole 9 tablet or medicament propelling movement to sick position can, to sick position on the solid tablet or wash sick position with liquid medicament. Silica gel on the end of the medicine feeding rod 9 can enable the contact surface of the medicine feeding rod 9 and the push rod 10 to be well sealed, when a patient needs to be flushed with liquid medicine, the push rod 10 only needs to be taken out of the dilator, the liquid medicine is sucked into a cavity in the middle of the push rod 10, and the push rod 10 is inserted into the dilator for standby. At this time, the liquid medicine in the push rod 10 cannot flow out of the push rod 10 due to the sealing state of the contact surface between the dosing rod 9 and the push rod 10; when the solid tablet needs to be used for a patient, the pushing rod 10 is only required to be taken out, the solid tablet is placed in the pushing rod 10 and on the silica gel end of the dosing rod 9, the pushing rod 10 is inserted into the dilator for standby, the dosing rod 9 can be pulled downwards (below in a front view) to prevent the solid tablet from falling out of the pushing rod 10, and more space is reserved for placing the tablet.

The one end that pushing ram 10 is located the expander is served and can be dismantled the connection and spout medicine head 11, spout and be provided with the several through-hole on the medicine head 11, can fix a suction head of connecting a similar to the syringe head in spouting medicine head 11, when inhaling liquid medicament, can make liquid medicament keep can not flow in pushing ram 10. The medicine spraying head 11 can use a disposable medicine spraying head, and the medicine spraying heads 11 in different ranges can be replaced according to different diseased part conditions so as to meet the use requirements of patients.

The pesticide spraying head 11 is in a semicircular arc shape, and through holes in the pesticide spraying head 11 are arranged along the circumferential direction of the pesticide spraying head 11 by 360 degrees. When the medicine feeding rod 9 is pushed, the through holes arranged at 360 degrees can enable the medicine liquid to be uniformly sprayed to the affected part and the peripheral area for diminishing inflammation and sterilizing.

In another embodiment of the drug delivery device, the drug delivery device is a drug delivery rod 9 which penetrates through the sleeve 13 and is in sliding fit with the sleeve 13, and a drug placing cavity is arranged at one end of the drug delivery rod 9, which is positioned in the dilator. It can be understood that, can only place the solid tablet or the cotton ball that has the liquid medicine in putting the medicine cavity, can't place liquid medicament, and when the solid tablet or the cotton ball that takes the liquid medicine placed, can block and can not fall out in putting the medicine cavity, when medical personnel need to medicine to the patient, only need touch diseased part gently with the cotton ball of tablet or taking the liquid medicine, with the medicine coating at diseased part for the drug composition can act on diseased part can.

Supporting blocks 2 are arranged on two sides of the connecting ends of the first expansion plate 1, the second expansion plate 12 and the shell 8, strip-shaped grooves are formed in the positions, opposite to the supporting blocks 2, of the shell 8 and along the moving direction of the supporting blocks 2, and the other ends of the supporting blocks 2 extend into the strip-shaped grooves and are in sliding fit with the strip-shaped grooves. The first expansion board 1 and the second expansion board 12 are supported on the housing 8 through the supporting block 2, and are in sliding fit with the housing 8, so that the first expansion board 1 and the second expansion board 12 are not obstructed during movement.

The specific working mode is as follows: before use, medical staff take the push rod 10 out of the dilator, place solid tablets or inhale liquid medicaments according to the condition of a patient, and insert the push rod 10 into the dilator after placement; during the use, medical personnel revolve and twist knob 7 for a certain distance is opened to first expansion board 1, second expansion board 12, and at this moment, medical personnel need handheld knob 7 and casing 8 remain stable, prevents that first expansion board 1, second expansion board 12 from withdrawing because exogenic action, promotes impulse rod 10, makes impulse rod 10 be close to the position of sickening after, promotes for medicine pole 9 again, makes liquid medicament spray at the position of sickening, perhaps places the solid tablet at the position of sickening. Because the propelling rod 10 and the medicine feeding rod 9 can adjust the propelling distance, the medicine feeding rod 9 can be slowly pushed according to the state of illness of the affected part of the patient, and the spraying force of the medicine liquid is adjusted, so that the discomfort of the patient is avoided.

The above embodiments are preferred embodiments, it should be noted that the above preferred embodiments should not be considered as limitations of the present invention, and the scope of the present invention should be limited by the scope defined by the claims. It will be apparent to those skilled in the art that various modifications and enhancements can be made without departing from the spirit and scope of the invention, and such modifications and enhancements are intended to be within the scope of the invention.
