[0002] Endoscopic liquid delivery devices are used in minimally invasive surgical procedures such as laparoscopic surgery and gastroenteroscopy. They deliver liquid to the human body cavity to flush out blood, residues and other substances in the cavity tissue, so as to obtain better visibility during endoscopic diagnosis and treatment. However, traditional endoscope liquid delivery devices do not have a liquid storage bottle storage device, and there is a problem that the liquid storage bottle is easy to fall during use. In addition, the existing peristaltic pump main shaft lacks a liquid blocking part.

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0016] like Figures 1 to 4 As shown, the utility model discloses an endoscope liquid delivery device, which adopts a technical solution including a peristaltic pump, which also includes a main unit 1 and a pump head 5. A motor is arranged in a casing 101 of the main unit 1, and the pump head 5 is connected to the outside of the casing 101. The motor is connected to a main shaft 106, which extends out of the casing 101 and is connected to the pump head 5, and a waterproof ring 105 is installed between the main shaft 106 and the casing 101.

[0017] In this embodiment, the liquid storage bottle uses a disposable infusion bottle 2. In order to prevent it from tipping over and to reduce the occupied space when idle, a folding frame 3 is installed on the side of the housing 101. Figure 3 As shown, the folding frame 3 includes a fixing frame 301. There are two fixing frames 301, which are vertically and parallelly installed on the casing 101 using bolts. The fixing frames 301 are in the shape of angle steel and have two mutually perpendicular connecting plates. One connecting plate is connected to the casing 101, and both ends of the other connecting plate are axially connected to the transverse bracket 302. In order to improve the stability of the transverse bracket 302, one end of the transverse bracket 302 is axially connected to the fixing frame 301, and the other end is a free end. The free ends of the two transverse brackets 302 connected by the two ends of a fixing frame 301 are axially connected to the two ends of the vertical connecting rod 304. The free ends of the two transverse brackets 302 hinged at the upper ends of the two fixing frames 301 are axially connected to the two ends of the upper connecting rod 303, and the free ends of the two transverse brackets 302 hinged at the lower ends are axially connected to the two ends of the lower connecting rod 305.

[0018] In order to be able to drag the infusion bottle 2 from the bottom, a bottom bracket 306 is installed between the two horizontal brackets 302 hinged at the lower ends of the two fixing frames 301. The bottom bracket 306 is plate-shaped, and the bottom surface of the infusion bottle 2 is slidably connected to the top surface of the bottom bracket 306.

[0019] In order to ensure that the folding frame 3 can only be folded upwards and not downwards, the lower end faces of the two fixed frames 301 are connected by an orienting plate, which is a square strip. The hinge between the transverse bracket 302 and the fixed frame 301 is located above the square strip. When the transverse bracket 302 is perpendicular to the fixed frame 301, the transverse bracket 302 is connected to the orienting plate, and the transverse bracket 302 cannot continue to rotate downward.

[0020] In order to prevent the folding frame 3 from automatically opening when in the folded state, bolts and nuts are provided at all folding positions of the folding frame 3, and damping is generated at the rotating positions by the bolts and nuts.

[0021] In order to control the liquid delivery more conveniently and intuitively, a knob switch 102, a push switch 103 and a display 104 are arranged on the main unit 1. The main unit 1 contains a microprocessor, a buzzer, a photoelectric switch connector, a rotary encoder and a motor frequency converter. The photoelectric switch connector is used to monitor whether the pump head 5 is loose, the rotary encoder is used to detect the rotation speed of the main shaft 106, the push switch 103 and the foot switch 6 are both used to control the start and stop of the motor, the buzzer is used for abnormal alarm, the knob switch 102 can be used to adjust the output power, and by adjusting the knob switch 102, the microprocessor controls the motor frequency converter to make the motor output at the specified power.

[0022] The working principle of this utility model:

[0023] Open the folding frame 3, and all the hinges of the folding frame 3 rotate until the horizontal bracket 302 is perpendicular to the fixed frame 301. At this time, the bottom bracket 306 is located on the table. Put the infusion bottle 2 into the folding frame 3, connect the end of the pump tube 4 to the infusion bottle 2, open the upper cover of the pump head 5, put the pump tube 4 into the pump head 5, close the upper cover to compress the pump tube 4, turn on the push switch 103, adjust the knob switch 102 to the expected flow rate, step on the foot switch 6 to start the peristaltic pump host 1, and pump out the cleaning liquid in the infusion bottle 2. When the pump tube is worn and leaks, the waterproof ring 105 can prevent the liquid from flowing along the main shaft 106 to the motor.

[0024] After use, the pump tube 4 is taken out from the pump head 5 , the infusion bottle 2 is taken out from the folding frame 3 , the infusion bottle 2 is discarded, and the folding frame 3 is folded and leaned against the housing 101 .

[0025] The circuits and mechanical connections involved in the present utility model are conventional means used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments, which belong to common knowledge.

[0026] Components not described in detail herein are prior art.
