Abstract
The utility model discloses an intrauterine device placer with a degradable cap, the intrauterine device placer belongs to the field of medical devices and is characterized in that the intrauterine device placer is composed of the degradable cap, a catheter, a push rod and a positioning block, the degradable cap can be arranged into a smooth cap-shaped object with the spherical or conical front end, the materials thereof are biodegradable materials, antibiotic drugs, prostaglandin inhibitor drugs and hemostasis drugs can be added therein, the degradable cap is sheathed at the front end of the catheter, the positioning block is sheathed on the catheter, and the push rod is inserted in the catheter. The intrauterine device placer can avoid the shortcomings of the tubular intrauterine device placer with the thin-walled sharp circular port-like front end, the degradable cap of the intrauterine device placer constitutes the front end with the smooth streamline state, thereby effectively avoiding the injury and perforation of the uterus wall during the placement process, and the drugs contained in the degradable cap can further enhance the effects of preventing the infection, the discomfort, the bleeding and other complications.
Description
Technical field
This utility model belongs to medical instruments field, and it relates to the intrauterine device placement device with degradable medicated cap.
Background technology
Up to now, using the most general intrauterine device placement utensil is that tubular type is placed utensil, it contains conduit and two basic building blocks of push rod, wherein the function of conduit is: one, force intrauterine device to take place moulding and it is brought in its leading portion pipe, its two, intrauterine device is led in the uterine cavity; The function of push rod is: will containing the intrauterine device that is contained in the disposed tubes leading portion, to release pipe outer and reach to uterine cavity.Drawing materials of aforementioned conduit is the medical plastic material, its physics's characteristics are that front end is the open round mouth of the sharp property of thin-walled, its drawback is that this sharp property opening constitutes the structural defect that can produce big resistance in the progradation, also constitute the utensil inducement that can produce Uterus wall damage and perforation in the progradation, Uterus wall degree in the wrong is big more, then the axial thrust that applies of conductive pipe is big more, the probability that endometrial impairment and the perforation of Uterus wall apparatus take place thus is also big more, in the big uterus (bend anteflexion or back) of spending in the wrong, uterine cicatrix, age of sucking the uterus, muscular tumor causes under the situations such as distortion uterus and malformed uterus, and the probability that aforementioned damage or perforation take place obviously increases.Secondly, placement of intrauterine devices is to belong to the aggressive operation, exist and cause possibility of infection in the antidromicity uterine cavity, this infections is easier to generation under long situation of Uterus wall damage, perforation and uterine cavity bleeding time, up to now, for preventing such infection, usually preventative whole body is used antibiotic after placement of intrauterine devices, and the deficiency of its existence is to take the whole body administration, but not topical, cause the local drug effect of uterine cavity relatively poor, and have the adverse side effect of systemic administration.
The utility model content
The purpose of this utility model is to found-and kind the uterus is bent degree good, the no sharp property front end of compliance and can be cooperated the intrauterine device of in utero medication to place utensil in placement of intrauterine devices, to avoid existing tubular type placement utensil drawback or deficiency structurally.
The purpose of this utility model is achieved in that the intrauterine device placement device that originally has the degradable medicated cap, it is characterized in that it is by the degradable medicated cap, conduit, push rod and locating piece are formed, the degradable medicated cap is set to have the calotte of slick dome shape or taper front end, it is drawn materials and is Biodegradable material, in this Biodegradable material, can add antibiotics, prostaglandin inhibitor class medicine and hemostasis class medicine, conduit, push rod and locating piece are all drawn materials and are the medical plastic material, the degradable cap sleeve places the front end of conduit, locating piece is placed on the conduit, and push rod is inserted in the conduit.Conduit is elongated tubular product such, and its transverse shape can be set to circle or ellipse; Push rod is elongated rod-shaped, and its transverse shape can be set to circle or ellipse corresponding to the conduit transverse shape.Conduit leading portion and the degradable medicated cap that is placed on catheter proximal end are used to store up receive and are strain and the intrauterine device of rounding state.
Using method of the present utility model: degradable medicated cap of the present utility model, conduit, push rod and locating piece can be provided with its size and form as required, are adapted to store up and receive all on-fixeds in the intrauterine device of Uterus wall.This utility model can with the intrauterine device received of supporting storage be encapsulated in the packaging unit, for disposable use.During use, require to open packing according to asepsis earlier, intrauterine device is placed in the conduit leading portion with rounding state, the degradable cap sleeve is placed catheter proximal end, push rod is inserted in the conduit, configure locating piece in supravasal set, after preparing according to the conventional person that requires to do the receiver of placement of intrauterine devices, with the degradable medicated cap the preceding set it is sent in the cervical canal collar extension, the operator can put forth effort through conduit, low conduit is pushed into uterine cavity through cervical canal, feel stops to advance after reaching purpose zone (at the bottom of the palace), with hands fixedly pusher grip end and pumpback conduit simultaneously, the intrauterine device that thus degradable medicated cap and storage is contained in the conduit leading portion pushes away conduit and keeps somewhere in uterine cavity, then extracts conduit and push rod out by the uterus.
Because this utility model is that Biodegradable material is made, it begins softening dissolving after uterus is oozed out body fluid and juice is contacted in it at once entering, drawn in moulding intrauterine device elastic force effect in addition, capsule can very fast disintegrate fragmentates and is dissolved gradually, and intrauterine device launches and is located in the uterine cavity.
Construction features of the present utility model and beneficial effect:
1, to have avoided existing front end be the drawback of the sharp property of thin-walled round mouth conduit to this utility model, it has changed physics's characteristics of catheter proximal end with the degradable medicated cap, constituted the front end of smooth streamline form, can effectively avoid Uterus wall damage in the put procedure, perforation and birth control apparatus incarceration, dystopy thus, more outstanding is has promoted and has spent the compliance that big uterus (bend anteflexion or back), uterine cicatrix, age of sucking uterus, muscular tumor cause distortion uterus and malformed uterus to bending.
2, the degradable medicated cap is drawn materials and is Biodegradable material, its reason is the safety and the reliability of existing Biodegradable material, and mode is sent to the uterine cavity part with antibiotics, prostaglandin inhibitor class medicine and hemostasis class medicine whereby, has promoted prevention placement of intrauterine devices postoperative infection, do not accommodate the effect that complication such as hemorrhage takes place.Clinical research shows: the degradable medicated cap can dissolve disintegrate rapidly in uterine cavity, intrauterine device can be deployed condition set rapidly.
3, this utility model has increased the degradable medicated cap on original tubular type placement device is signed an undertaking the structure basis, it is drawn materials and draws materials with preparation and the existing capsule-type medicine that generally adopts already capsular and prepare identical, cheap, easy to prepare, possess the adaptability of China's national situation and the prospect of applying.
