Embodiment 1

[0042] Please refer to figure 1 , figure 1 It is a structural schematic diagram of a cannula device for taking vaginal secretions / medication for children and young women of the present invention. A vaginal secretion / administration sleeve device for children and adolescent women, the secretion / administration sleeve device, the secretion / administration sleeve device includes a suction tube 1, and the suction tube 1 A scale is marked on it, and the total length of the scale is 15cm, wherein the scale is marked with a thickened thick line 12 at 4cm, 5cm, 8cm, and 11cm; the outer diameter of the suction tube 1 is 4-4.5mm; The distal end of the suction tube 1 is conical; the distal end and the side wall of the suction tube 1 are provided with suction holes 11, and the suction holes 11 on the side walls are distributed randomly, and the number of suction holes 11 is at least 3; The inner wall of the suction tube 1 is closely attached to a metal guide wire 13, and the metal guide wi...

Embodiment 2

[0053] This embodiment is basically the same as the embodiment, the difference is that please refer to image 3 , image 3 It is a schematic diagram of the partially enlarged structure of the metal guide wire. The distal end of the metal guide wire 13 is also provided with a guide head 132, the guide head 132 is tapered, and the end of the guide head 132 is an arc structure, the diameter of the guide head 132 is less than 4mm, and the diameter of the guide head 132 is 4-4 mm. A suction tube of 4.5mm is matched, and the cost is low, so that the suction hole 11 at the end of the suction tube 1 can be avoided from damaging the inner wall of the vagina when it is inserted.

[0054] The device for taking vaginal secretions / medication cannula for children and young women of the present invention can control the length when taking vaginal secretions, and the vaginal secretions will not be polluted by the outside world, reducing the work difficulty of medical staff, avoiding damage, ...

Abstract

The invention relates to a vaginal secretion fetching / medicating cannula device for female children and adolescents. The secretion fetching / medicating cannula device comprises a suction tube and a negative-pressure device. Suction holes are formed in the far end and sidewalls of the suction tube; a metal guide wire clings to the inner wall of the suction tube; the negative-pressure device comprises a drum body, a piston and a drawing rod; a connecting port is formed in the far end of the drum body; and the connecting port is connected to the suction tube. The vaginal secretion fetching / medicating cannula device disclosed by the invention has the following advantages: 1) the cannula device, when used for fetching vaginal secretions, is controllable in length, and the vaginal secretions are prevented from being contaminated by external environment, so that working difficulty of medical personnel is reduced and injuries are avoided; and the cannula device, which is good in controllability, can be used for as a special medical apparatus for fetching the vaginal secretions from the female children and adolescents; and 2) the cannula device, when conducting vaginal and vulvar administration, can precisely control administration positions, and meanwhile, by virtue of a threaded structure on the drum body, the cannula device is capable of completing drug loading and administration precisely; therefore, the cannula device has a broad application prospect in the clinical field.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a cannula device for taking vaginal secretions / medication for children and young women. Background technique [0002] In recent years, the incidence of vaginitis in children and adolescent women has been increasing year by year. Due to physiological and anatomical characteristics, the etiology and clinical manifestations of vaginitis in children and adolescent women are different from those of adults. Children and adolescent women lack estrogen glycogen, and vaginal Thin mucous membrane, poor defense function, the vagina is close to the anus, often polluted by urine and feces, and hygiene habits are not developed, which makes it easy for various pathogenic bacteria to invade and cause infection. [0003] During the diagnosis and treatment of vaginitis in children and adolescent women, it is necessary to extract vaginal secretions to assist in clinical diagnosis, and to gu...
