[0002] The Endoscopy Delivery System (EDS) is a reusable medical device consisting of a polysaccharide hemostatic powder and a powder delivery system. It is a safe and effective medical device for controlling upper and lower gastrointestinal bleeding. The powder delivery system components include an air pump structure and a powder delivery channel (including a tee and delivery catheter). One end of the air pump structure is connected to the tee via a connector. Randomly installing the tee and connector often causes the powder inlet of the tee to be oriented differently from the air pump handle, affecting the powder's ability to enter the tee and, in turn, the air within the air pump structure to move the powder. This prevents the powder from being delivered smoothly through the delivery catheter to the hemostatic site, reducing the applicability of the connector and the reliability of the air pump structure.

[0040] The Endoscopy Delivery System (EDS) is a reusable medical device consisting of a powder of polysaccharide hemostatic material and a powder delivery system. It is a safe and effective medical device for controlling upper and lower gastrointestinal bleeding. It can be applied to lesions that may be located in difficult-to-reach areas. It also helps prevent rebleeding after EMR (endoscopic mucosal resection) / ESD (endoscopic submucosal dissection) and can be used as an additional therapy to any other traditional techniques for controlling bleeding.

[0041] The powder delivery system assembly includes an air pump structure and a powder feeding channel (including a tee and a delivery conduit). A connector is provided on the external fixed sleeve at one end of the air pump structure, and the connector is threadedly connected to the first port of the tee. Randomly installing the tee and the connector usually causes the powder inlet of the tee and the air pump handle to be in different directions, thereby affecting the powder entering the tee, and further affecting the blowing effect of the gas in the air pump structure on the powder, resulting in the powder being unable to be smoothly delivered to the hemostasis site through the delivery conduit, reducing the applicability of the connector and the reliability of the air pump structure.

[0042] Figure 1 The figure schematically shows a structural diagram of a handle structure for an air pump according to an embodiment of the present utility model. Figure 2 The figure schematically shows a structural diagram of a handle structure for an air pump according to an embodiment of the present utility model from another perspective. Figure 3 for Figure 2 Schematic diagram of the cross-sectional structure in the AA direction. Figure 1 、 2 As shown in Figures 1 and 3, the present invention proposes a handle structure for an air pump. The handle structure for an air pump in the present invention includes a housing 10, a tube body 20, and a connector 30. A receiving cavity 14 is formed in the housing 10. The housing 10 has a first opening, which is in communication with the receiving cavity 14. A portion of the tube body 20 is disposed in the receiving cavity 14. One end of the tube body 20 passes through the first opening and extends to the outside of the housing 10. An annular boss 21 is disposed on the outside of one end of the tube body 20. The connector 30 is sleeved on the outside of one end of the tube body 20 and can rotate around its own axis. The side of the annular boss 21 facing the housing 10 can abut against the connector 30. The end of the connector 30 facing away from the housing 10 is used to connect and cooperate with an external connecting component.

[0043] According to the technical solution of the present invention, the accommodating cavity 14 of the shell 10 can accommodate the tube body 20 and the connecting piece 30. The tube body 20 is used to transport gas. The connecting piece 30 is sleeved on the outside of the tube body 20 located outside the shell 10 and can abut against the annular boss 21, which can prevent the connecting piece 30 from slipping out from one end of the tube body 20, and the connecting piece 30 can rotate around its own axis, which is convenient for adjusting the rotation angle and cooperating with the external connecting parts. The handle structure of the present invention can freely select the fixed angle of cooperation with the external connecting parts, so that the angle of the external connecting parts can be adjusted, thereby improving applicability.

[0044] In some embodiments of the present invention, Figure 5 、 6 As shown in Figure 7, the connector 30 includes a connected limiting portion 31 and an annular portion 32. The limiting portion 31 is located between the annular boss 21 and the housing 10. The annular portion 32 is sleeved on the outside of the annular boss 21. The annular portion 32 has an accommodating cavity 321. The limiting portion 31 is provided with a through hole, which is connected to the accommodating cavity 321. The annular boss 21 can abut against the limiting portion 31. In this embodiment, the limiting portion 31 is located between the annular boss 21 and the housing 10, which can prevent the overall connector 30 from sliding off the tube body 20. At the same time, it can also be matched and connected with external connecting components, thereby improving reliability. The accommodating cavity 321 in the annular portion 32 is used to accommodate the annular boss 21, and the annular portion 32 can also be matched and connected with external connecting components to achieve the connection between the external connecting components and the air pump structure.

[0045] In some embodiments of the present invention, Figure 5As shown, the outer surface of the annular portion 32 is provided with a plurality of first ridges 13. The extension direction of the first ridges 13 is parallel to the axial direction of the annular portion 32. The plurality of first ridges 13 are spaced apart along the circumferential direction of the annular portion 32. In this embodiment, the plurality of first ridges 13 are arranged in a ring-shaped and spaced-apart manner along the circumferential direction of the annular portion 32. When an operator needs to rotate the connector 30, their fingers will press on the outer surface of the connector 30. Due to the protruding arrangement of the first ridges 13, the contact area between the fingers and the outer surface of the connector 30 can be increased. This can increase the friction force exerted by the operator on the annular portion 32 during rotation, thereby facilitating the rotation of the connector 30 and improving convenience.

[0046] In some embodiments of the present invention, Figure 7 As shown, the inner surface of the annular portion 32 is provided with a first threaded structure 322, which is used to threadably engage with an external connecting component. In this embodiment, the external connecting component is a tee, which has a first port, a second port, and a third port. The first port is used to mate with the connecting member 30, the second port is used to connect to the powder supply device, and the third port is used to discharge the powder blown by the air pump structure.

[0047] Specifically, the outer surface of the first port in this embodiment has a second threaded structure, and the first threaded structure 322 of the annular portion 32 and the second threaded structure of the tee can be threadedly connected. Since the annular portion 32 and the integral connecting piece 30 can rotate around the axial direction of the annular portion 32, after the first threaded structure 322 of the annular portion 32 and the second threaded structure of the tee are pre-tightened, the fixed angle direction of the tee and the connecting piece 30 can be adjusted, and then the connecting piece 30 and the tee are completely fixed, so that the second port of the tee can be vertically upward. After the powder enters the tee through the second port, it can also fall due to its own gravity, so that the powder can fully fall into the tee and fully interact with the gas.

[0048] Specifically, in other embodiments of the present invention, the inner surface of the first port of the tee can be provided with a third threaded structure, and the outer surface of the annular portion 32 can be provided with a fourth threaded structure. The third threaded structure can be fastened in conjunction with the fourth threaded structure, and can also realize the fastening operation between the connector 30 and the tee.

[0049] In some embodiments of the present invention, Figure 4As shown, the handle structure for the air pump further includes a regulating valve 40, a control assembly, and a drive assembly. The regulating valve 40, the control assembly, and the drive assembly are all disposed in the accommodating chamber 14. The regulating valve 40 is disposed on the tube body 20. The drive assembly is connected to the regulating valve 40, and the control assembly is electrically connected to the drive assembly. The control assembly can drive the regulating valve 40 via the drive assembly to adjust the flow rate of the gas in the tube body 20. In this embodiment, the control assembly can transmit a signal to the drive assembly and cause the drive assembly to drive the regulating valve 40. Since the regulating valve 40 is disposed on the tube body 20, the flow rate of the gas in the tube body 20 can be controlled.

[0050] In some embodiments of the present invention, Figure 4 As shown, the drive assembly includes a motor 61 and an electric connection component 62. The motor 61 is drive-connected to the regulating valve 40 and electrically connected to the control assembly. The housing 10 has a second opening, and the electric connection component 62 is arranged at the second opening. One end of the electric connection component 62 is electrically connected to the motor 61, and the other end of the electric connection component 62 is used to be electrically connected to an external power source. In this embodiment, the driving end of the motor 61 is connected to the regulating valve 40. The motor 61 can drive the regulating valve 40 under the signal transmission of the control assembly to control the opening and closing angle in the regulating valve 40, thereby controlling the gas flow rate in the tube body 20. The electric connection component 62 is used to electrically connect the motor 61 to an external power source, thereby realizing the power supply to the motor 61 and the control assembly.

[0051] In some embodiments of the present invention, Figure 4 As shown, the control assembly includes a control board 51, on which buttons 52 are provided. The housing 10 is provided with a third opening, and the buttons 52 are disposed in the third opening, with portions of the buttons 52 exposed outside the housing 10. The control board 51 is electrically connected to the drive assembly. In this embodiment, the control board 51 is a printed circuit board (PCB), and portions of the buttons 52 are exposed outside the housing 10. This allows an operator to actuate the buttons 52, thereby implementing corresponding control commands and driving the regulating valve 40 via the PCB and motor 61.

[0052] In some embodiments of the present invention, Figure 1 、 2As shown in Figure 3, the housing 10 includes a first half shell 11 and a second half shell 12. A first groove is provided on the side of the first half shell 11 facing the second half shell 12, and a second groove is provided on the side of the second half shell 12 facing the first half shell 11. The first groove and the second groove are engaged to form an accommodating chamber 14. In this embodiment, the arrangement of the first half shell 11 and the second half shell 12 facilitates assembly and disassembly of the housing 10, improving assembly and disassembly efficiency. The accommodating chamber 14 formed by the engagement of the first groove and the second groove facilitates accommodating the regulating valve 40, the control assembly, the drive assembly, and the pipe body 20.

[0053] In some embodiments of the present invention, Figure 2 As shown, the outer surface of the housing 10 is provided with a plurality of second ridges 33. The second ridges 33 extend perpendicularly to the longitudinal direction of the housing 10 and are spaced apart along the longitudinal direction of the housing 10. In this embodiment, when an operator needs to pick up the handle structure, the plurality of second ridges 33 facilitates increasing the friction between the operator and the housing 10, making it easier for the operator to pick up the handle. Moreover, due to the high friction, the housing 10 is not easily slipped out of the operator's hand during operation, thereby improving reliability.

[0054] In some embodiments of the present invention, Figure 5 As shown, the tube body 20 is provided with a clamping member 80, which is clamped to the first opening. In this embodiment, the clamping member 80 can be fixedly clamped to the first opening, thereby fixing the tube body 20 and ensuring that the tube body 20 does not move significantly or otherwise move when the handle structure is in operation.

[0055] Furthermore, in this embodiment, if Figure 4 As shown, a connecting pipe 70 is provided at the first opening, and a clamping member 80 is clamped in the connecting pipe 70 for clamping the clamping member 80 .

[0056] Furthermore, the handle structure of the present invention has adjustable air pressure and is compact and portable, and can be used almost anywhere (the handle design is more convenient for medical staff to operate). In addition, the front end of the handle structure of the air pump is equipped with a connector 30, which is convenient for mating with external connecting parts, thereby facilitating the dispensing of powder.

[0057] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
