Description

Fetal head aspirator

Technical Field

The utility model relates to the technical field of midwifery equipment, in particular to a fetal head aspirator.

Background

The fetal head aspirator is an auxiliary medical appliance in female production, and is usually stretched into a delivery passage to attract and assist in pulling the fetal head under the premise that the fetus cannot be delivered normally and naturally, so that the fetal inlet is discharged out of the delivery passage, the conventional fetal head aspirator generally comprises a suction head device and a rubber catheter and an air extractor, a long straight stainless steel tube is usually arranged on the suction head device to realize connection with the rubber catheter, the delivery passage is generally expanded by a pair of obstetric forceps in the delivery process, and the long straight stainless steel tube of the fetal head aspirator with the structure is difficult to place and use between the opened pair of obstetric forceps due to limited opening angles of the pair of obstetric forceps, so that the long straight stainless steel tube is very inconvenient for on-site use of medical staff. Meanwhile, as the skull of the fetus is softer, the head of the fetus is easily sucked by the suction head device to deform, and how to avoid the deformation of the head to the maximum extent in the sucking process is a problem to be solved at present.

Disclosure of Invention

The utility model aims to provide a fetal head aspirator, wherein a shell and a handle rod which are obliquely arranged are more beneficial to the cooperative use between opened obstetric forceps, and a fetal head aspiration reset mechanism is arranged at one end of a small diameter of a conical suction head bowl, so that the deformation of the head in the aspiration process is avoided to the maximum extent, and the problems in the prior art are solved.

The technical scheme adopted for solving the technical problems is as follows: the utility model provides a child head aspirator, includes the casing that the level set up, the toper suction head bowl is installed to the one end of casing, and the other end of casing is connected with the handle pole that the slope was arranged, and the aspiration pump is installed to the upper end of handle pole, and the extraction opening of aspiration pump is linked together with the toper suction head bowl through the pumping pipeline, installs the switch in one side that the handle pole is close to the casing, and the switch is connected with the aspiration pump through control line, installs child head suction reset mechanism in the path one end that the toper suction head bowl is close to the casing, child head suction reset mechanism is including setting up the elasticity flange in the path one end of toper suction head bowl, and the big diameter one end protrusion setting of elasticity flange to toper suction head bowl. And a pressure gauge is arranged on one side of the handle rod, which is far away from the switch. The included angle between the handle rod and the shell is 60-70 degrees. The elastic convex plate is provided with leakage holes which are circumferentially arranged, and the position of the elastic convex plate fixed at one end of the small diameter of the conical suction head bowl is 3 cm to 5cm away from the shell.

The utility model has the positive effects that: the fetal head aspirator comprises a shell and a handle rod which are obliquely arranged, wherein the end part of the shell is provided with a conical suction head bowl, and the handle rod is provided with an air sucking pump and a switch.

Detailed Description

The utility model relates to a fetal head aspirator, which comprises a shell 1 horizontally arranged as shown in fig. 1 and 2, wherein one end of the shell 1 is provided with a conical sucker bowl 2, the other end of the shell 1 is connected with a handle rod 3 which is obliquely arranged, and an included angle formed between the handle rod 3 and the shell 1 is an acute angle, so that a medical staff can hold the handle rod 3 to put the shell 1 between opened obstetrics forceps, and the conical sucker bowl 2 enters into an obstetric canal to suck the head of a fetus. Wherein the conical suction head bowl 2 can be made of medical silica gel, so that the safety performance of the surgical operation is ensured.

The upper end of the handle rod 3 is provided with an air pump 4, the air pump 4 can provide negative suction pressure, an air pumping port of the air pump 4 is communicated with the conical suction head bowl 2 through an air pumping pipeline 5, and the head of a fetus can be sucked and fixed after the conical suction head bowl 2 enters a birth canal, so that the fetus is conveniently assisted to be discharged from the birth canal. The suction pump 4 is provided with a threshold value of safe suction negative pressure, and after suction reaches a preset suction negative pressure value, the continuous suction negative pressure is stopped, and the suction pump can also be matched with a pressure release valve for use together, so that the damage to a fetus caused by excessive pressure is avoided when the fetus head is sucked.

A switch 6 is arranged on one side of the handle rod 3 close to the shell 1, the switch 6 is connected with the air pump 4 through a control circuit, and medical staff can realize the start and stop operation of the air pump 4 by touching the switch by one hand while holding the handle rod 3.

In order to avoid the deformation of the head in the sucking process, a fetal head sucking and resetting mechanism is arranged in one end of the conical suction head bowl 2, which is close to the small diameter of the shell 1, as shown in fig. 3, the fetal head sucking and resetting mechanism comprises an elastic convex plate 7 arranged in one end of the small diameter of the conical suction head bowl 2, the elastic convex plate 7 is arranged to protrude towards one end of the large diameter of the conical suction head bowl 2, after the conical suction head bowl 2 is used for sucking and fixing the head of a fetus, the conical suction head bowl 2 is in a tightening state and is attached to the head of the fetus, the elastic convex plate 7 can further protrude outwards in the tightening state, the fetal head can be pushed outwards by the convex elastic convex plate 7 at the moment, the situation that the head is clamped and becomes narrow is avoided, and the sucking deformation of the head is avoided to the greatest extent when the head is sucked and fixed.

Further, in order to facilitate the operator to observe the suction pressure value in the production process, a pressure gauge 8 is installed on one side of the handle rod 3 far away from the switch 6, the number of suction negative pressure can be displayed on the pressure gauge 8 in real time, and when the operator observes that the specified suction pressure is reached, the switch 6 is closed in time, so that unnecessary damage to a fetus is avoided.

Further, for convenience of use, the included angle between the handle bar 3 and the housing 1 is 60-70 degrees.

Further, in order to ensure that the arrangement of the elastic convex plate 7 does not affect the normal suction negative pressure, as shown in fig. 3, the elastic convex plate 7 is provided with leakage holes 9 which are circumferentially arranged, and the periphery of the elastic convex plate 7 is fixed on the inner wall of the conical suction head bowl 2. In order to enable the conical suction head bowl 2 in the tightened state to further protrude outwards, the elastic protruding plate 7 is fixed at the position of the small diameter end of the conical suction head bowl 2, and the distance between the elastic protruding plate and the shell 1 is 3-5cm.

The technical scheme of the utility model is not limited to the scope of the embodiments of the utility model. The technical content that is not described in detail in the utility model is known in the prior art.
