Description

A perfusion joint device, a perfusion mechanism and a cleaning and disinfection device

Technical Field

The utility model relates to the technical field of perfusion equipment, and more specifically, to a perfusion joint device. In addition, the utility model also relates to a perfusion mechanism including the perfusion joint device. Furthermore, the utility model also relates to a cleaning and disinfecting device including the perfusion mechanism.

Background Art

With the development of modern medicine, endoscopes are increasingly used in minimally invasive surgeries. Specifically, the endoscope is passed through the mouth into the stomach or into the body through other natural orifices.

An endoscope usually includes an operating part, an insertion part and a connecting part, wherein the insertion part includes an insertion tube and a tip located at the head end of the insertion tube, and a camera unit, a lighting unit, a working forceps channel, a water vapor channel, etc. are provided inside the insertion part. The tail end of the insertion tube is connected to one side of the operating part, and a connecting part is provided on the other side of the operating part to connect to a host and a display. When in use, the insertion part is inserted into the human body from the oral cavity or other natural orifices of the human body, and the medical staff holds the operating part to control the position of the tip in the human body. The treatment instrument extends from the tip through the working forceps channel to sample or treat the patient's lesion location.

Endoscopes are invasive instruments that are contaminated with many types of contaminants, including proteins, mucopolysaccharides, fats, and carbohydrates. If the endoscopes are not cleaned and disinfected, cross infection is very likely to occur, endangering the health and life safety of patients. The routine operations for cleaning and disinfecting endoscopes are as follows: manually scrub the outside of the endoscope, fill the inner cavity of the endoscope with liquid and air to achieve bedside pre-cleaning of the endoscope, then transport the endoscope to the disinfection room and immerse the endoscope in disinfectant, fill the inner cavity of the endoscope with liquid, hold a soft cloth to wipe the outer surface of the endoscope, hold a brush to scrub the inner cavity wall of the endoscope, and finally fill the endoscope with liquid again to complete the cleaning of the endoscope.

However, when manually decontaminating an endoscope, the endoscope is subjected to the operation of filling-brushing-filling. It is necessary to disconnect the perfusion channel before brushing and reconnect the perfusion channel after brushing. The operation steps are numerous and the burden on medical staff is heavy.

In summary, how to reduce the operational difficulty of endoscope cleaning is a problem that currently needs to be solved urgently by those skilled in the art.

The joint body 1 has an inlet channel 101, a liquid inlet channel 102, a liquid outlet channel 103, a brush channel 105 and a movable channel 104. The joint inner core 2 is slidably arranged in the movable channel 104. The peripheral surface of the first shaft section 21 of the joint inner core 2 is sealed with the peripheral wall of the movable channel 104 to divide the movable channel 104 into a first chamber and a second chamber that are independent of each other. The inlet channel 101 is conductively connected to the first chamber, the liquid outlet channel 103 and the brush channel 105 are both conductively connected to the second chamber, the liquid inlet channel 102 is conductively connected to the liquid outlet channel 103, and the sliding of the joint inner core 2 can make the liquid inlet channel 102 and the brush channel 105 connected or closed. One end of the restoring member 3 is connected to the joint inner core 2, and the other end is connected to the inner wall of the joint body 1 to push the joint inner core 2 to reset.

As shown in Figure 2, the joint body 1 is a hollow structure, and the inlet channel 101, the liquid inlet channel 102, the liquid outlet channel 103, the brush channel 105, and the movable channel 104 opened inside the joint body 1 are staggered, and a joint core 2 is inserted in the movable channel 104, and a first sealing ring 7 is sleeved on the circumference of the first axial section 21 of the joint core 2, so that when the joint core 2 moves along the length direction of the movable channel 104, the first chamber and the second chamber on both sides of the first axial section 21 of the movable channel 104 are guaranteed to be independent of each other.

Furthermore, as shown in Figures 2 and 4, a retractable or deformable restoring member 3 is provided at one end of the movable channel 104, and one end of the restoring member 3 is connected to the joint body 1, and the other end is connected to the joint core 2, so that the joint core 2 can be pushed back to its original position under the action of the force of the restoring member 3.

Finally, as shown in Figure 2, the inlet channel 101 is connected to the first chamber, so the fluid outside the connector body 1 can flow into the first chamber through the inlet channel 101; the liquid outlet channel 103 and the brush channel 105 are both connected to the second chamber, so the brush or other structure extending from the liquid outlet channel 103 can pass through the second chamber and the brush channel 105 and extend out of the connector body 1; the liquid inlet channel 102 is connected to the liquid outlet channel 103, so the liquid outside the connector body 1 can flow into it through the liquid inlet channel 102 and flow out of the connector body 1 through the liquid outlet channel 103; and the opening of the liquid outlet channel 103 inside the connector body 1 and/or the opening of the brush channel 105 inside the connector body 1 are located on the side wall of the second chamber, then the opening of the liquid outlet channel 103 inside the connector body 1 and/or the opening of the brush channel 105 inside the connector body 1 can be blocked by the connector inner core 2, so that the liquid inlet channel 102 and the brush channel 105 are connected or closed.

The liquid flowing in through the liquid inlet channel 102 does not need to be transferred through the second chamber, but can flow out directly through the liquid outlet channel 103. Such an arrangement has a simple structure and is conducive to achieving a miniaturized design.

When in use, the connector inner core 2 moves to a preset position to cover the opening of the liquid inlet channel 102 located on the side wall of the second chamber and/or the opening of the brush channel 105 inside the connector body 1. Since the liquid outlet channel 103 is connected to the brush channel 105 through the liquid inlet channel 102 and the second chamber, the liquid inlet channel 102 and the brush channel 105 can be controlled to be connected or closed.
