Description

Technical Field

[0001] The present application relates to the field of medical equipment, and in particular to a medical sterile wound irrigator. Background Art

[0002] Wound suppuration is one of the most common surgical symptoms. Purulence is a sign of wound infection and abnormal purulent secretions. It is difficult to get infected without damage or wounds, but there will be liquid overflowing from the damaged area of ​​traumatic wounds or surgical wounds. This liquid is a nutrient solution suitable for bacteria as a culture medium. Bacteria multiply in the exudate, and the clear exudate becomes a thick infected liquid. For the treatment of infected wounds, you can clean the wound thoroughly to wash away the purulent secretions. Antibiotics can be used to inhibit bacterial reproduction. A good environment can promote wound healing.

[0003] At present, saline is generally used for flushing. The specific operation process is: use a syringe to extract saline from the saline bottle, and then flush the wound. This is repeated, which is cumbersome and inefficient. Not only is the flushing effect not obvious, but it also indirectly causes wound contamination. Utility Model Content

[0004] In order to improve flushing efficiency and reduce wound contamination, the present application provides a medical sterile wound flusher.

[0005] The present application provides a medical sterile wound irrigator, which adopts the following technical solution:

[0006] A medical sterile wound irrigator comprises a liquid spray tube, a balloon, a liquid outlet tube and a needle, wherein one end of the balloon is fixedly connected to the liquid spray tube, and the other end is fixedly connected to the liquid outlet tube, and the end of the liquid outlet tube away from the balloon is fixedly connected to the needle. The invention also comprises a conical cavity capable of being inserted into a saline bottle, wherein the needle passes through both ends of the conical cavity, a circle of shell is arranged at the bottom of the conical cavity, the liquid outlet tube enters the conical cavity from the shell, the head of the conical cavity is in contact with the needle and forms a straight line, and the head of the conical cavity can be opened and closed relative to the needle; a gravity ball ring is arranged in the conical cavity, the gravity ball ring is passed through the needle, and the end of the liquid outlet tube is fixedly connected to the gravity ball ring.

[0007] By adopting the above technical solution, a conical cavity is arranged at one end of the liquid outlet pipe, and a needle is fixedly arranged at the end of the liquid outlet pipe. The needle penetrates through both ends of the conical cavity, and the conical cavity and the needle form a larger conical stabbing body, which can be easily inserted into the rubber bottle cap of the saline bottle; and a gravity ball ring is placed in the conical cavity. The gravity ball ring is sleeved on the needle and fixedly connected to the liquid outlet pipe which is also sleeved on the needle. When the conical cavity is inserted into the saline bottle cap, the head of the conical cavity is opened. Under the action of gravity, the gravity ball ring drags one end of the liquid outlet pipe and the needle to sink to the bottom of the saline bottle. At this time, when the balloon is pinched by hand, the saline in the saline bottle is sucked into the liquid outlet pipe from the needle, then enters the balloon from the liquid outlet pipe, and finally is ejected by the liquid spraying pipe to achieve wound cleaning. The whole process is in a closed state, that is, aseptic operation is realized, wound contamination is reduced, and the flushing efficiency is improved. In addition, when the saline in the saline bottle is used up, a new saline bottle can be replaced and used continuously, saving resources.

[0008] Optionally, an opening and closing door is arranged at a position of the conical cavity close to the needle. One end of the opening and closing door away from the head of the conical cavity is hinged to the conical cavity, and an opening and closing button is arranged at the bottom of the conical cavity. The opening and closing button is fixedly connected to the opening and closing door.

[0009] By adopting the above technical solution, an opening and closing door is opened at the head of the conical cavity. The opening and closing door is hinged to the conical cavity. Under normal conditions, the opening and closing door is closed and on the same curved surface as the conical cavity. When it needs to be opened, the opening and closing door is pushed outwards through the opening and closing button, so that the gravity ball ring drags the needle to fall to the bottom of the saline bottle.

[0010] Optionally, a push rod is arranged on each of the opposite sides of the housing. The push rod vertically penetrates through the conical cavity, and a spring is arranged between the push rod and the housing. A sliding hole is opened at the bottom of the conical cavity below the spring, and the end of the push rod away from the spring is fixedly connected to the opening and closing door.

[0011] By adopting the above technical solution, two push rods are arranged on the outside of the housing, and a spring is arranged between the housing and the push rods. Under normal conditions, the spring is in a normal telescopic state, and the push rods pull the opening and closing door to make it closed. When the push rods on both sides of the bottom of the conical cavity are pinched and moved closer to each other in the opposite direction, due to the lever action, the end of the push rod away from the spring moves in the opposite direction, thereby pushing open the opening and closing door and making the opening and closing door in an open state.

[0012] Optionally, the push rod includes a vertical rod, a first inclined rod and a second inclined rod. The vertical rod is arranged parallel to the needle. One end of the first inclined rod is fixedly connected to one end of the vertical rod, and the other end is fixedly connected to one end of the second inclined rod. The other end of the second inclined rod is fixedly connected to the opening and closing door. The first inclined rod forms an angle with the vertical rod, and the first inclined rod forms an angle with the second inclined rod. The opening directions of the two angles are opposite.

[0013] By adopting the above technical solution, the first oblique rod and the second oblique rod form a certain angle, and are arranged inwardly relative to the vertical rod in the conical cavity. When the vertical rods on both sides of the bottom of the conical cavity are pinched, the second oblique rod is tilted outward due to the lever action, thereby lifting the opening and closing door. The design of the first oblique rod and the second oblique rod makes the opening and closing effect of the opening and closing door more ideal and effectively utilizes the space.

[0014] Optionally, the liquid outlet tube is spirally coiled from the portion close to the needle tail to the balloon.

[0015] By adopting the above technical solution, the liquid outlet pipe is set to a spirally coiled structure, which can not only effectively extend the length of the liquid outlet pipe and facilitate operation, but also not appear too long and convenient to organize.

[0016] Optionally, an adjustment switch is provided at one end of the liquid outlet tube close to the needle.

[0017] By adopting the above technical solution, an adjustment switch is arranged on the liquid outlet pipe, which can block the output of saline when not in use, and can also prevent the saline from being sprayed out due to accidental pinching of the balloon. In addition, the output amount of saline can be adjusted by the adjustment switch to suit the actual situation.

[0018] Optionally, the end of the liquid spray tube away from the balloon is a 75° elbow structure.

[0019] By adopting the above technical solution, the spray pipe is set to a 75° elbow structure, which, combined with the human body's usage habits, can be better aimed at the wound and improve the cleaning efficiency.

[0020] Optionally, a one-way check valve is provided at one end of the liquid outlet tube close to the balloon.

[0021] By adopting the above technical solution and setting the one-way check valve, the outputted brine can be prevented from flowing back, thereby ensuring that the brine in the brine bottle is not contaminated.

[0022] The gravity ball ring is provided with a liquid suction hole, and the side wall of the needle head is provided with a liquid inlet hole, and the liquid suction hole corresponds to the liquid inlet hole.

[0023] By adopting the above technical solution, a liquid inlet hole is opened on the side wall of the needle, so that saline can enter from the liquid suction hole on the gravity ball ring and then enter into the liquid outlet tube from the liquid inlet hole of the needle, effectively increasing the output rate of saline.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. By setting a conical cavity at one end of the liquid outlet pipe, a needle is fixedly arranged at the end of the liquid outlet pipe, and the needle penetrates through both ends of the conical cavity. The conical cavity and the needle form a larger conical puncture body, which can be easily inserted into the rubber bottle cap of the saline bottle. A gravity ball ring is placed in the conical cavity. The gravity ball ring is sleeved on the needle and fixedly connected to the liquid outlet pipe which is also sleeved on the needle. When the conical cavity is inserted into the saline bottle cap, the head of the conical cavity is opened. Under the action of gravity, the gravity ball ring drags one end of the liquid outlet pipe and the needle to sink to the bottom of the saline bottle. At this time, when the balloon is pinched by hand, the saline in the saline bottle is sucked into the liquid outlet pipe from the needle, then enters the balloon from the liquid outlet pipe, and finally is sprayed out by the liquid spraying pipe to achieve wound cleaning. The whole process is in a closed state, that is, aseptic operation is achieved, reducing wound contamination and improving the flushing efficiency.

[0026] 2. By opening an opening and closing door at the head of the conical cavity, the opening and closing door is hinged to the conical cavity. When it needs to be opened, through the opening and closing button, the opening and closing door is pushed outwards, so that the gravity ball ring drags the needle to fall to the bottom of the saline bottle.

[0027] 3. By setting the liquid outlet pipe into a spiral coiled structure, not only can the length of the liquid outlet pipe be effectively extended, which is convenient for operation, but also it will not appear too long and is convenient for arrangement. Description of the Drawings
