Abstract: A bite device is configured to be placed in the mouth (92) of a patient, facilitates insertion of soft tubes (91) from the outside into the mouth (92) of the patient, and includes a bite member (2) and an auxiliary member (3). The bite member (2) includes an abutment portion (21), a biting portion (216) extending outwardly from one side of the abutment portion (21), a sleeve portion (22) opposite to the biting portion (216), and a central hole (23) for insertion of one soft tube (91) therethrough. The auxiliary member (3) includes a fixing plate structure (31) having a main auxiliary hole (317) removably sleeved on the sleeve portion (22), and at least one secondary auxiliary hole (318) for insertion of another soft tube (91) into the mouth (92) of the patient.

Abstract: An endoscope (100) includes an insertion tube device (2) and a control device (8). The insertion tube device (2) includes an elastic support unit (3), a lens unit (4), and a tubular sleeve unit (7). The elastic support unit (3) includes a distal disk (31), a proximal disk (33), an intermediate disk (32), first and second springs (34, 35) respectively connected between the disks (31, 32, 33). The lens unit (4) includes a lens seat (41) and a lens module (42). The tubular sleeve unit (7) is sleeved on the lens seat (41) and the elastic support unit (3). The control device (8) includes a grip (81), and an angulation control module (85) connected to the insertion tube device (2). The angulation control module (85) is operable to move the distal disk (31) and to deflect the first spring (34), thereby controlling angle of the distal disk (31).

Abstract: A nasogastric tube structure is disclosed which comprises a first tube, a clamping member and a positioning member. The first tube has a front necking opening, a rear opening, a stopper ring on a wall thereof adjacent to the rear opening and an engaging groove on the wall thereof adjacent to the stopper ring. The clamping member comprises two corresponding positioning segments and a C-shaped clip portion for connecting the two positioning segments and engaging with the engaging groove. The positioning member is sleeved on the two positioning segments.

Abstract: The invention relates to a truncated feeding tube comprising a first tube, a second tube, and a joint element. One terminal of the first tube and the second tube is removably connected to the two terminals of the joint element. A patient can connect the first and second tubes by the joint element or remove the second tube. Since the joint element can be separated from the first and second tubes, the joint member can be simply replaced when it is damaged without replacing the first or second tube. A positioning member is disposed on a front portion of the second tube, so that an endoscopic technology can be used to clamp the positioning member and the inner wall of the stomach or the duodenum by a hemostatic clip, and the front portion of the second tube is positioned in the stomach or the duodenum to avoid sliding displacement.
