Description

Amniotic fluid collecting device

Technical Field

The utility model relates to a medical instrument especially relates to a amniotic fluid collection system.

Background

Stem cells are a kind of cells with self-renewal ability and multi-differentiation potential, and in medical research, stem cells on human body are collected for research. Recent researches show that stem cells exist in amniotic fluid, and the amniotic fluid released by women during childbirth is wasted, so that some hospitals can collect the amniotic fluid in advance through an amniotic fluid collecting device during childbirth, and the amniotic fluid can be used for scientific researches. The prior amniotic fluid collecting device adopts a hose with a puncture head to accurately puncture the amniotic membrane in the uterus of a female to suck the amniotic fluid by the experience of a doctor, but the mode has some disadvantages. If the puncture is realized through the experience of a doctor, the puncture head is sharp, and the hidden danger of injuring a fetus exists; if the amniotic fluid is stored in the amniotic sac, the amniotic fluid has a shallow depth, when the amniotic fluid is insufficient, the puncture head punctured from the upper part can not well absorb the amniotic fluid, and further puncture brings about greater potential safety hazard.

Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

As shown in fig. 1 and 2, the utility model is a specific embodiment of the amniotic fluid collecting device. The embodiment comprises a collecting bag 1, a guide pipe 2 and a collecting head 3, wherein the collecting bag 1 is provided with an outlet valve 11 connected to an outlet and an inlet valve 12 connected to an inlet, and two ends of the guide pipe 2 are respectively connected with the inlet valve 12 and the collecting head 3; the collecting head 3 comprises a metal round head 31, a plurality of main inlets 32 are arranged on the surface of the metal round head 31, the main inlets 32 are communicated to the guide pipe 2, and the guide pipe 2 is a hose.

The utility model discloses when using, because of its structure that does not have the puncture, consequently be applicable to and carry out the collection work of amniotic fluid when cesarean deliery. When the abdominal incision is to be carried out and the parturient is produced, a doctor opens a small opening for the parturient, the small opening cuts the skin tissue, the uterine wall and the amniotic membrane, then the collecting head 3 extends into the amniotic membrane sac through the small opening, the collecting head 3 and the guide tube 2 extend into the amniotic membrane sac all the time, when the collecting head 3 cannot extend smoothly, the collecting head 3 reaches the bottom of the amniotic membrane sac, the collecting head 3 can be fully soaked by the amniotic fluid, the pressure difference between the inside and the outside of the amniotic membrane sac can be relied on through the siphon principle, the pressure difference enables the amniotic fluid to be siphoned from the amniotic membrane sac to the collecting bag 1, and the amniotic fluid is collected into the collecting bag 1 through the collecting head 3 and the guide tube 2; or a vacuum pump is connected to the outlet valve 11 to suck the amniotic fluid. When collected, the collection head 3 and the guide tube 2 can be taken out, the inlet valve 12 is closed for storage, the guide tube 2 and the inlet valve 12 can adopt a detachable structure, and the collection bag 1 is separately stored and transported after the guide tube 2 is detached. After the amniotic fluid is collected and finishes, the doctor continues to open the incision and cuts open the abdomen to the lying-in woman and produces, like the amniotic fluid collection process before the lying-in woman produces among the prior art, the utility model discloses completion that also can be quick does not influence the normal childbirth of lying-in woman. Compared with the prior art, the utility model adopts the way of sinking the bottom of the metal round head 31, thereby ensuring the sufficient collection of the amniotic fluid; moreover, the metal round head 31 is adopted, so that the fetus cannot be injured, and the safety is higher; the guiding tube 2 is a hose, the structure of the guiding tube is soft, the metal round head 31 at the head can reach the bottom more smoothly, the guiding tube 2 can be fully extended into the amniotic sac, the compression on human tissues can not be caused, and the guiding tube can be well applied to amniotic fluid collection during cesarean section.

As a modified specific embodiment, the collecting head 3 further comprises a metal straight pipe 33 connected to the rear part of the metal round head 31, the metal straight pipe 33 is communicated with the inside of the metal round head 31, and the metal straight pipe 33 is connected with the guide pipe 2; the outer wall of the straight metal pipe 33 is distributed with a plurality of auxiliary inlets 34.

As shown in fig. 1 and 2, firstly, the main inlets 32 on the surface of the metal round head 31 can ensure good liquid circulation and are not easy to block; however, a plurality of solid tissues still exist in amniotic fluid, the metal round head 31 can be contacted with the bottom of the amniotic sac after sinking to the bottom, the solid tissues sinking to the bottom can be more, and in order to avoid the possibility that the metal round head 31 is blocked, the metal straight pipe 33 and a plurality of auxiliary inlet 34 structures are further arranged, so that the metal straight pipe 33 and the metal round head 31 form a circulation structure which is more difficult to block at different heights, and the smooth collection of the amniotic fluid is ensured.

As a modified embodiment, an elastic baffle flap 4 is arranged on the outer wall of the guide tube 2, the baffle flap 4 being arranged opposite the collection head 3 and at an acute angle to the guide tube 2.

As shown in figure 2, the arrangement of the above specific structure is used for preventing the guide tube 2 from sliding outwards after being inserted into a human body, so that the influence on the smooth collection of the amniotic fluid is avoided. During the specific use, rely on the osculum of incising, will hinder inside flap 4 stretches into human outer incision, rely on the angle structure's that outwards struts hindrance flap 4 card at the incision edge (because of lying-in woman's delivery is comparatively painful or injected the circumstances such as anesthesia, painless needle, consequently this card is established and can not bring extra discomfort for the lying-in woman), make guide tube 2 can outwards not roll off. After the amniotic fluid is collected, the doctor further cuts the incision to disable the blocking flap 4, and can take out the guide tube 2 and the collecting head 3.

As a modified embodiment, the blocking flaps 4 are provided in pairs on both sides of the guide tube 2.

As shown in fig. 2, the blocking flaps 4 are preferably arranged on both sides of the guiding tube 2 in pairs to ensure the stable engagement of the blocking flaps 4 with the human tissue and to stably position the guiding tube 2.

As a modified embodiment, the blocking flap 4 has a head 41 made of silicone material for abutting against human tissue. The head 41 of the specific silica gel material is used for supporting the blocking flap 4 on human tissues without hurting human bodies, and the whole blocking flap 4 is made of hard materials to ensure the structural strength of the blocking flap, so that the blocking flap can be better clamped at the edge of the incision.

As a modified embodiment, the guide tube 2 is a hose made of silicone material. The guiding tube 2 that specifically sets up the silica gel material is with lower costs, uses generally in medical field, the use needs when adaptation amniotic fluid is collected.

Above only the utility model discloses an it is preferred embodiment, the utility model discloses a scope of protection not only limits in above-mentioned embodiment, and the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
