Description

Technical Field

[0001] The utility model relates to a debridement water jet cutter head device with an exhaust function. Background Art

[0002] Currently, a water jet debridement system is a new medical device that uses high-pressure water to cleanse, remove damaged tissue, and sterilize. It includes a main connector, a water inlet pipe, a water outlet pipe, a water bag, and a water jet blade. The main connector is connected to the main unit, the water inlet pipe connects the main connector to the water bag, and the water outlet pipe connects the main connector to the water jet blade. Physiological saline in the water bag flows from the water inlet pipe into the main connector and then into the main unit. A water pump in the main unit pumps the saline, generating high pressure, which flows from the water outlet pipe into the water jet blade, where it then cleans the wound. Chinese Patent Publication No. CN215230751U discloses a debridement treatment device with both debridement and negative pressure therapy functions that utilizes this principle to clean wounds.

[0003] However, during clinical use, it was found that when water flows from the water inlet pipe into the main connector or when the water bag is replaced, air will be generated in the water inlet pipe.

[0030] Figure 2 It is a structural schematic diagram of the sealed joint of the utility model. DETAILED DESCRIPTION

[0031] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0032] like Figure 1 、 2 As shown, a debridement water jet cutter head device with exhaust function includes a main joint 1, a water inlet pipe 2, a water outlet pipe 3 and a sealed joint 4;

[0033] The main connector 1 is used to connect to the host;

[0034] The water inlet pipe 2 is connected to the main connector 1 and is used to receive liquid;

[0035] The water outlet pipe 3 is connected to the main connector 1 and is used to discharge liquid;

[0036] The airtight joint 4 is connected to the water inlet pipe 2, and the airtight joint 4 is provided with an exhaust channel 5 connected to the water inlet pipe 2, and the airtight joint 4 is provided with a sealing member 6 that seals and blocks the exhaust channel 5. Specifically, when air is generated in the water inlet pipe 2, since the exhaust channel 5 is connected to the water inlet pipe 2, the air in the water inlet pipe 2 can enter the exhaust channel 5. At this time, the needle of the syringe can be used to pierce the seal 6 and then extend into the exhaust channel 5, and then the air is extracted by the syringe, so as to extract the air in the water inlet pipe 2, thereby preventing the air in the water inlet pipe 2 from entering the main unit and affecting the operation of the water pump in the main unit, thereby ensuring the normal operation of the debridement water jet system, and safely, effectively and practically reducing the cost of clinical medical treatment. Among them, when the needle on the syringe is pulled out from the seal 6, the seal 6 can restore the sealing state.

[0037] Alternatively, the seal 6 can be squeezed and deformed by a syringe to form a passage. The syringe can then be used to suction the exhaust passage 5 and the water inlet pipe 2, thereby extracting the air in the water inlet pipe 2. This prevents the air in the water inlet pipe 2 from entering the main unit and affecting the operation of the water pump within the main unit, thereby ensuring the normal operation of the debridement water jet system. When the syringe releases the squeeze on the seal 6, the seal 6 can return to its sealed state. In this embodiment, the specific structure of the main unit is well known to those skilled in the art and will not be described in detail in this embodiment.

[0038] like Figure 1 As shown, the debridement water jet cutter head device with exhaust function can also include a water bag 7, one end of the water inlet pipe 2 is connected to the water bag 7, and the other end of the water inlet pipe 2 is connected to the main connector 1.

[0039] like Figure 1 As shown, the debridement water jet cutter head device with exhaust function can also include a water jet cutter head 8, one end of the water outlet pipe 3 is connected to the main joint 1, and the other end of the water outlet pipe 3 is connected to the water jet cutter head 8, and the water outlet pipe 3 is used to discharge liquid into the water jet cutter head 8.

[0040] Specifically, after the main connector 1 is plugged into the main unit, the water inlet pipe 2 is used to connect the liquid in the water bag 7. The liquid in the water bag 7 flows from the water inlet pipe 2 to the main connector 1 and then flows into the main unit. The water pump in the main unit pumps and pressurizes the liquid to generate high pressure. The high-pressure liquid flows from the main connector 1 into the water outlet pipe 3 and then into the water jet head 8. The water jet head 8 can then be used to clean the wound.

[0041] More specifically, when liquid flows from the water inlet pipe 2 into the main connector 1 or when the water bag 7 is replaced, air will be generated in the water inlet pipe 2. At this time, the needle of a syringe can be used to pierce the seal 6 and then extend into the exhaust channel 5, and then the air can be extracted through the syringe to remove the air in the water inlet pipe 2. This prevents the air in the water inlet pipe 2 from entering the main unit and affecting the operation of the water pump in the main unit, thereby ensuring the normal operation of the debridement water jet system. Of course, the seal 6 can also be squeezed and deformed by the syringe to form a passage, and then the exhaust channel 5 and the water inlet pipe 2 can be sucked out with the syringe to remove the air in the water inlet pipe 2. The liquid in the water bag 7 is physiological saline.

[0042] like Figure 1 As shown, the water jet cutter head 8 is further provided with a drain pipe 9.

[0044] like Figure 1 、 2 As shown, the sealed joint 4 may further be provided with a communication channel 10, and the exhaust channel 5 is connected to the communication channel 10;

[0047] One end of the second tube body 12 is connected to the sealed joint 4 and is connected to the other end of the connecting channel 10. The second tube body 12 is used to access the liquid. Specifically, the second tube body 12 is connected to the water bag 7 and is used to access the liquid in the water bag 7. The connecting channel 10 is used to connect the first tube body 11 and the second tube body 12. The liquid in the water bag 7 flows through the second tube body 12, the connecting channel 10 and the first tube body 11 in sequence and then flows into the main joint 1. The exhaust channel 5 is located above the connecting channel 10.

[0048] like Figure 1 、 2 As shown, the sealed joint 4 may include a joint seat 13, an exhaust pipe body 14 and a sealing cover 15;

[0049] The communication channel 10 is provided in the connector seat 13;

[0050] The first tube body 11 is connected to one end of the connector base body 13 and communicates with one end of the communication channel 10;

[0051] The second tube body 12 is connected to the other end of the connector base body 13 and is connected to the other end of the communication channel 10;

[0052] One end of the exhaust pipe body 14 is connected to the joint base 13, and the sealing cover 15 is connected to the other end of the exhaust pipe body 14;

[0053] The exhaust channel 5 is arranged in the exhaust tube body 14, the sealing member 6 is arranged in the sealing cover 15, and the sealing cover 15 is also provided with a pumping interface 16; specifically, the needle of the injection passes through the pumping interface 16 and pierces the sealing member 6 and then extends into the exhaust channel 5.

[0054] like Figure 2 As shown, one end of the connector base 13 is provided with a first plug hole 17, and the first tube 11 is sealed and plugged into the first plug hole 17;

[0055] A second inserting hole 18 is defined at the other end of the connector base 13 , and the second tube 12 is sealed and inserted into the second inserting hole 18 .

[0056] like Figure 1 、 2 As shown, the exhaust pipe body 14 is arranged obliquely to the joint base body 13 , and the exhaust pipe body 14 and the joint base body 13 are integrally formed.

[0057] In this embodiment, the water outlet pipe 3 is a braided tube, and the sealing member 6 is made of silicone rubber.

[0058] To sum up, when air is generated in the water inlet pipe 2, since the exhaust channel 5 is connected to the water inlet pipe 2, the air in the water inlet pipe 2 can enter the exhaust channel 5. At this time, the needle of the syringe can be used to pierce the seal 6 and then extend into the exhaust channel 5 and then the air is extracted through the syringe to extract the air in the water inlet pipe 2, or the seal 6 can be squeezed with a syringe to form a passage after the seal 6 is squeezed and deformed, and then the exhaust channel 5 and the water inlet pipe 2 are sucked by the syringe to extract the air in the water inlet pipe 2, thereby avoiding the air in the water inlet pipe 2 from entering the main unit and affecting the operation of the water pump in the main unit, thereby ensuring the normal operation of the debridement water jet system, and safely and effectively reducing the cost of clinical medical care.
