DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a delivery table for obstetrics and gynecology, in which a patient is shifted from a laid-down state to a state of examination and delivery during an examination or delivery in obstetrics and gynecology.

[0002]

2. Description of the Related Art Conventionally, this kind of obstetrics and gynecology delivery table includes a type in which a crotch support and a heel support (hereinafter simply referred to as a leg support) are installed before a patient is introduced, and a type in which a nurse or the like is introduced after a patient is introduced. There are two types;

[0003]

By the way, in the former type, since the supporting device is installed before the introduction of the patient, the appearance of the supporting device is mechanical and gives a sense of fear to the patient.
In addition, there is a problem in that the legs are in the way when lying on the delivery table, causing pain to the difficult-to-behave maternity and requiring the assistance of a nurse.

[0004] In the latter type, a nurse must be installed for each delivery after introduction of a patient,
In addition, there is a problem that a powerless nurse is labor intensive and time-consuming because it has to be transported from a storage place. Therefore, despite the fact that it is a detachable type, some hospitals leave the legs attached,
In this case, the same problem as the former type occurred.

Furthermore, in both cases, since the legs of the patient are fixed by the supporting devices, there is no freedom of the legs, and the patient performs examination and delivery while feeling pain.

[0006] The present invention is intended to solve the above-mentioned problems. The purpose of the present invention is to provide a bed state at the time of introduction of the patient, so that the patient will not be afraid of the patient, and the pedestal device is not required. An object of the present invention is to provide an obstetrics and gynecology delivery table that can be incorporated into a delivery table and a part of the bed changes into a leg support after the patient is introduced.

[0007]
