    摘要： An endorectal cooling device (ECD) includes an elongated body, a cooling fluid circuit, and a gas bubble removal device. The elongated body includes an insertable portion for insertion into a patient's rectum and an external portion that remains external to the rectum. The cooling fluid circuit is defined in the elongated body from the external portion to the insertable portion and circulates cooling fluid to regulate a temperature of a cooling surface on the insertable portion. The gas bubble removal device can include a coil, a tube, a mesh, and/or a hole that is disposed on or defined in the insertable portion of the elongated body, such as the cooling surface. A low-pressure source, such as a vacuum pump or a Venturi structure, can be fluidly coupled to the gas bubble removal device to remove fluid and bubbles by a suction force after the ECD is inserted into the rectum.

    摘要： The present disclosure relates to a device for conveying a local cryoanesthesia type painless syringe, and more particularly, to a device for conveying a local cryoanesthesia type painless syringe, the device having a first needle guide hole formed at the center of a skin anesthetizing plate, which is mounted on one side of a device body to come in contact with the skin, to instantaneously cool the epidermis and block neural transmission, a second needle guide hole formed at the center of a Peltier element, which is in close contact with a rear side surface of the skin anesthetizing plate, to absorb heat generated from the skin anesthetizing plate, a third needle guide hole formed at the center of a heat dissipation block, which connects a lower side thereof with a second heat dissipation plate having a cooling fan, positioned at a lower side of the device body, attached thereto using a heat pipe, to absorb heat from the Peltier element and dissipate heat, a fourth needle guide hole formed at the center of a first heat dissipation plate, which is in close contact with a rear side surface of the heat dissipation block, to absorb heat of the heat dissipation block and dissipate heat to the outside, a support clip, configured to loosely clamp one side of a syringe cylinder, formed at an upper side of a moving stand to allow a syringe needle coupled to the syringe cylinder to be positioned on a center line of the fourth, third, second, and first needle guide holes, a moving stand conveyor configured to move the moving stand toward the skin to convey the syringe cylinder so that the syringe needle of the syringe cylinder is able to pass through the fourth, third, second, and first needle guide holes and be inserted at a predetermined depth into the skin, a moving clip in which an insertion groove is formed to, unlike the support clip of the moving stand, tightly clamp a flange fitted thereinto formed at a rear side of the syringe cylinder, and a moving clip position controller configured to, corresponding to a short length (b) or a long length (c) of the syringe needle coupled to the syringe cylinder that remains fixed to the moving clip, place an end of the syringe needle at a set point (a).
