Description

A head position aid

Technical Field

The utility model relates to the technical field of obstetric aids, in particular to a head position obstetric aid.

Background Art

Obstetrics and gynecology is one of the four major disciplines in clinical medicine. It mainly studies the etiology, pathology, diagnosis and prevention of diseases of the female reproductive organs, the physiological and pathological changes of pregnancy and childbirth, the prevention and treatment of high-risk pregnancy and dystocia, female reproductive endocrinology, family planning and women's health care, etc. Obstetrics and gynecology is not only closely related to clinical disciplines such as surgery, internal medicine, and pediatrics, but also requires basic knowledge of multiple disciplines such as modern diagnosis and treatment techniques, clinical pharmacology, pathology and embryology, anatomy, and epidemiology. It is also a discipline with its own characteristics and requires comprehensive clinical and basic knowledge. The midwife is an indispensable medical device in the obstetrics and gynecology department of the hospital. Malposition of the fetus, delivery of multiple births, premature delivery, etc. all require the midwife to assist in delivery.

However, most of the existing head-positioning midwives do not have an expansion function, which reduces the efficiency of the baby's delivery. At the same time, the head-positioning suction cup cannot be disassembled, which increases the difficulty of cleaning for medical staff.

Utility Model Content

The purpose of the utility model is to solve the shortcomings of the prior art and to propose a head position aid. The device can realize the expansion function and is easy to disassemble and install the suction cup, so that when the device is used for multiple pregnant women, only different suction cups need to be replaced.

In order to achieve the above purpose, the utility model provides the following technical solutions:

A head position aid comprises a straw, wherein a cavity is provided inside the straw, a piston rod is movably provided inside the cavity, an armrest ring is fixedly provided on one side of the straw, a catheter is fixedly provided on the side of the straw away from the armrest ring, a plurality of external threads are fixedly provided on the outer wall of one end of the catheter extending out of the straw, a suction cup is connected to one end of the catheter close to the external threads, and a through hole is provided in the middle of the suction cup;

The rear ends of the upper and lower ends of the straw are rotatably connected to fixed rods through a rotating shaft, and the two fixed rods are fixedly connected to expansion rods on the sides close to the suction cups. A movable block is movably provided at the middle of the front end of the straw, and a connecting rod is fixedly connected to the middle of the side of the movable block close to the handle, and a pulling block is fixedly connected to the end of the connecting rod away from the movable block.

Through the above technical solution, medical staff pulls the pulling block, and with the use of the connecting piece and the rotating shaft, the fixed rod drives the expansion rod to expand to the upper and lower ends, and then the clamping block is connected in the clamping groove to limit the pulling block 18 to realize its expansion function, and then pull the handle to make the piston disk evacuate the cavity. At this time, negative pressure is formed inside the suction cup, which sucks the baby's head to ensure the smooth delivery of the baby.

Furthermore, one end of the piston rod located in the cavity is fixedly connected to a piston disk;

Through the above technical solution, gas is pumped into the cavity through the movement of the piston disk.

Furthermore, one end of the piston rod away from the piston rod passes through the handrail ring and is fixedly connected to a handle;

Through the above technical solution, the piston rod is pulled by the handle.

Further, the catheter is connected to the cavity.

Furthermore, the conduit passes through the through hole and extends into the interior of the sucker, and the outer wall is threadedly connected with a sealing connection sleeve;

The above technical solution makes it easy for medical staff to disassemble and install the suction cup.

Furthermore, both upper and lower ends of the movable block are rotatably connected to the fixed rod with connecting pieces.

Furthermore, a clamping block is fixedly connected to the lower rear end of the pull block, and a plurality of clamping grooves are provided on the front end surface of the straw and located at the pull block, and the clamping block is clamped inside the clamping grooves;

Through the above technical solution, the pull block is limited and fixed.

The utility model has the following beneficial effects:

1. The utility model proposes a head-position midwife, in which a handle is pulled to cause a piston disc to evacuate air from a cavity, thereby forming a negative pressure inside the suction cup to suck the baby's head and ensure smooth delivery of the baby. A catheter passes through a through hole on the suction cup and is then connected to the catheter through a sealing connection sleeve inside the suction cup, so that the suction cup is easy to disassemble and install, and when the device is used by multiple pregnant women, only different suction cups need to be replaced.

2. The utility model proposes a head position aid, which pulls the pulling block, and with the use of the connecting piece and the rotating shaft, the fixed rod drives the expansion rod to expand to the upper and lower ends, and then the clamping block is connected in the clamping groove to limit the pulling block and realize its expansion function, further ensuring the smooth delivery of the baby and improving its practicality.
