A syringe adapter with a ball-typed valve has a base, a dosing tube mounted around the base and a resilient valve mounted in the base and the dosing tube. The base has a guiding groove and an inner liquid channel communicating with each other, as well as an exhaust channel. Liquid medicine injected into the syringe adapter flows through the guiding groove and causes the inner liquid channel to be injected into a patient's body. The liquid medicine remaining in the split is cleaned when cleaning fluid is injected to clean the syringe adapter. Air in the syringe adapter flows out through the exhaust channel and is not injected into the patient's body, so the patient is free from pain. Furthermore, elements and assembling processes of the syringe adapter are simplified and manufacturing cost of the syringe adapter is lowered.

The invention relates to an active controllable type capsule endoscope robot system comprising a capsule endoscope robot, a receiving memory, a motion control box and an image display system. A driving mechanism of the capsule endoscope robot generates the radial expansion and contraction of an oil bag and the extension and contraction of a capsule by a direct-current motor, a double-shaft multiplexing speed reducer and a geometer motion distribution mechanism and realizes progression and retrogression by matching according to a certain time sequence; after the capsule endoscope robot enters the gastrointestinal tract of a human body by oral administration, the capsule endoscope robot shoots the image information of each position of the gastrointestinal tract at real time by the self geometer creeping and transmits the image information outside the body in a wireless mode. In a part outside the body, the receiving memory is used for receiving and storing image data transmitted by the capsule endoscope robot in a wireless way; the motion control box controls the progression, the retrogression or the stop of the capsule endoscope robot in a wireless transmission mode so as to repeatedly observe a questionable position in the gastrointestinal tract; and the image display system reads and processes the image data recorded in the receiving memory at real time by a computer so as tobe observed and diagnosed by a doctor.

A bandage remains securely attached to the skin of a wearer during extended exposure to arid, humid or wet conditions. The bandage is readily removed from the attached condition upon application of pressure to its exterior surface. Adhesive portions of the contain pockets or microcapsules filled with an adhesive-inactivating ingredient. The pockets are formed in the backing layer. Microcapsules, if present, are incorporated in the adhesive. The adhesive inactivating ingredient comprises oil from vegetable source, mineral source or fatty acids. The wearer ruptures the pockets or microcapsules by applying pressure to the bandage above the adhesive portions. The adhesive-inactivating ingredient is thereby released at the skin-adhesive interface, permitting an easy, pain-free removal of the bandage.

The invention discloses a visual cognitive behavioral learning automatic training system of big and small mice. The visual cognitive behavioral learning automatic training system of the big and small mice comprises a training box, a main control unit, a video monitor, a microcontroller, a reward unit, a punishment unit, and a visual clue display unit. The microcontroller is connected with the main control unit through a universal serial bus (USB) interface in a communication mode. The training box is a structure that an opening is formed in the upper portion of the training box. The video monitor is arranged on the upper portion of the training box. The reward unit is composed of a food plate which is arranged on the lower portion of the training box, an infrared induction switch which is arranged on one side of the training box, and a water supply pipe which is arranged above the food plate and controlled by an electric control valve. The punishment unit is composed of a sweep frequency ultrasonic speaker which is arranged on the upper portion of the training box. The visual clue display unit comprises a capacitance-type touch screen and a display screen. The capacitance-type touch screen is arranged inside a frame. The lower frame of the frame is hinged with the side wall of the training box. The upper frame of the frame is connected with the side wall of the training box through a tension spring. The display screen is arranged at a rear position of the capacitance-type touch screen. The visual cognitive behavioral learning automatic training system of the big and small mice has the advantages that a visual cognitive behavioral learning automatic training to experimental animals is achieved.

A delivery device for delivering a substance intradermally into the skin of a patient including a housing for contacting the surface of the skin and a disposable cartridge to be received in the housing. The cartridge includes an internal reservoir containing a substance to be delivered to the patient, a plurality of micro skin penetrating members and a fluid channel extending between the micro skin penetrating members and the reservoir.

The invention discloses a preparation method of a CAR-T cell for treating AIDS-related lymphoma. A CD8+ T cell is used to produce the CAR-T cell, and the CD8-T cell derives from a cord blood T cell. The method includes the following steps: preparing cord blood mononuclear cells from cord blood, removing tumors and other cells by using a human T cell purification kit to obtain T cells, and carryingout separation by using magnetic beads to obtain the CD8+ T cell; activating the CD8+ T cell by using an appropriate medium and appropriate stimulation conditions; transferring CAR to the CD8+ T cellby using lentivirus to prepare the CAR-T cell; and amplifying the CAR-T cell in vitro by using cytokines and activating stimulators to achieve the desired effective dose. The invention also relates to the CAR-T cell prepared by the method, and an application thereof. The CAR-T cell prepared in the invention has a good cell activity and a high proliferation speed, and reduces the attack risk of GVHD; and only the CD8+T cell of the umbilical blood T cells of AIDS patients is used to prepare the CAR-T cell for, so the risk of input CAR-T infected with in-vivo HIV is reduced.
