[0038] Figure 1 This is a schematic diagram of the irrigation needle device shown in some embodiments of this specification. Figure 2 This is a schematic diagram of the adapter of the irrigation needle device according to some embodiments of this specification. See also Figure 1 , Figure 2 As shown, in one or more embodiments of this specification, the irrigation needle device may include: an adapter 1, a hose 2 connected to the adapter 1, and an irrigation needle 3 detachably connected to the hose 2.

[0039] In some embodiments, the adapter 1 may include a fixing member 10, the fixing member 10 having a first flow channel 11 and a second flow channel 12 inside, the first flow channel 11 and the second flow channel 12 being arranged along a first direction, and the fixing member 10 having two opposing clamping planes. In some embodiments, the worktable may be provided with clamping members for clamping the two clamping planes, thereby achieving overall fixation of the irrigation needle device.

[0040] In some embodiments, the adapter 1 may include a first adapter 13, which is integrally connected to the fixing member 10. The first adapter 13 is arranged along a second direction, which forms an angle with the first direction. The first adapter 13 communicates with the first flow channel 11. In some embodiments, the first adapter 13 may be connected to the first syringe.

[0041] In some embodiments, the adapter 1 may include a second adapter 14, which is integrally connected to the fixing member 10. The second adapter 14 is arranged along a third direction, which forms an angle with the first direction. The second adapter 14 communicates with the second flow channel 12, and a diaphragm check valve 15 is provided inside the second adapter 14. In some embodiments, the second adapter 14 may be connected to a second syringe.

[0042] In some embodiments, the adapter 1 further includes a first drug delivery end 16, which is integrally connected to the fixing member 10 and communicates with the first flow channel 11. In some embodiments, the first working fluid enters the first flow channel 11 through the first adapter 13, then enters the hose 2 through the first drug delivery end 16, and is irrigated by the irrigation needle 3 connected to the hose 2.

[0043] In some embodiments, the adapter 1 further includes a second drug delivery end 17, which is tubular and inserted into the interior of the fixing member 10 and communicates with the second flow channel 12. In some embodiments, the second working fluid enters the second flow channel 12 via the second adapter 14, then enters the hose 2 via the second drug delivery end 17, and is irrigated by the irrigation needle 3 connected to the hose 2.

[0044] In some embodiments, the first working fluid may be water. In some embodiments, the second working fluid may be paraformaldehyde.

[0045] In one or more embodiments of this specification, the hose 2 has a first hose flow channel 21 and a second hose flow channel 22 that are independent of each other. The first hose flow channel 21 is connected to the first flow channel 11, and the second hose flow channel 22 is connected to the second flow channel 12.

[0046] In some embodiments, the tubing 2 includes a needle fixing portion 23, which is an annular protrusion extending outward from the outer wall of the tubing 2. In some embodiments, the needle fixing portion 23 is used to limit the position of the irrigation needle 3, preventing the irrigation needle 3 from being excessively fitted onto the tubing 2, thus causing poor fluid flow.

[0047] In one or more embodiments of this specification, see Figure 1 , Figure 4 As shown, the irrigation needle 3 includes: a needle body 31 sleeved on the outside of the tubing 2, a needle 32 located at one end of the needle body 31, an abutment end 33 located at the other end of the needle body 31, and a tapered elastic fixing member 34 extending outward from the outer wall of the abutment end 33.

[0048] In some embodiments, the abutting end 33 is sleeved on the outside of the tubing 2 and abuts against the needle fixing portion 23 of the tubing 2 to determine the position of the irrigation needle 3. In some embodiments, the elastic fixing sleeve 34 is disposed outside the needle fixing portion 23 of the tubing 2, and the irrigation needle 3 is fixed to the tubing 2 by elasticity to prevent the irrigation needle 3 from falling off.

[0049] In some embodiments, a gap is provided between the elastic fastener 34 and the abutment end 33 to allow the elastic fastener 34 to deform. In some embodiments, in the initial state, the distance between the elastic fastener 34 and the outer surface of the abutment end 33 is relatively close. In some embodiments, when the irrigation needle 3 is assembled to the tubing 2, the elastic fastener 34 is spread open and sleeved on the outer edge of the needle fixing portion 23, and the circumferential force of the inner wall of the elastic fastener 34 is applied to the outer surface of the needle fixing portion 23 toward its center to achieve elastic fixation.

[0050] In some embodiments, the irrigation needle 3 may have a variety of different sizes to be assembled with the tubing 2 as needed.

[0051] In some embodiments, the diameter of the needle 32 is smaller than the diameter of the needle body 31.

[0052] In one or more embodiments of this specification, see Figure 2 , Figure 3 As shown, a portion of the side of the first delivery end 16 rests on a frustum surface A. For example, Figure 3 The upper surface of the first drug delivery end 16 is located on the upper side of a horizontally placed frustum A, and the lower side of the frustum A is... Figure 3 The dashed part in the text represents...

[0053] In some embodiments, the end of the first delivery end 16 furthest from the first adapter 13 rests on the small base of the frustum A. For example, the first delivery end 16 is located on... Figure 3 The right end provides a small base of the frustum A. For example, the first drug delivery end 16 is located at... Figure 2 The left end of the middle provides part of the large base of the frustum A.

[0054] In some embodiments, see Figure 3 As shown, the end of the second delivery end 17 near the end of the second adapter 14 (e.g., the left end in the figure) is located within the area of ​​the base of the frustum surface A.

[0055] In some embodiments, see Figure 3 As shown, the end of the second delivery end 17 away from the second adapter 14 (e.g., the right end in the figure) extends from the side of the frustum A and is outside the range of the small base of the frustum A.

[0056] In some embodiments, based on the above configuration, when the first delivery end 16 and the second delivery end 17 are inserted into the hose 2, deformation of the partition wall between the first hose flow channel 21 and the second hose flow channel 22 of the hose 2 can be caused to provide a tightening force. In some embodiments, based on the above configuration, the second delivery end 17, which can extend from the side of the frustum surface A, can penetrate into the hose 2 and guide the hose 2. Within this guiding range, the partition wall between the first hose flow channel 21 and the second hose flow channel 22 of the hose 2 is no longer deformed, thereby allowing fluid to pass smoothly.

[0057] In one or more embodiments of this specification, the second adapter 14 has a one-way valve accommodating space, and a diaphragm one-way valve 15 is disposed in the one-way valve accommodating space and embedded in the inner wall of the one-way valve accommodating space.

[0058] In some embodiments, see Figure 2 As shown, a limiting structure 141 is provided inside the one-way valve accommodating space. The limiting structure 141 abuts against the diaphragm one-way valve 15 to prevent deformation of the diaphragm one-way valve 15 in one direction. In some embodiments, the one-way valve accommodating space is rectangular in shape. In some embodiments, the left inner wall of the one-way valve accommodating space extends to the right to form an annular limiting structure 141, which can abut against the left surface of the diaphragm one-way valve 15.

[0059] In some embodiments, when the second working fluid passes through the diaphragm check valve 15 from left to right, the diaphragm check valve 15 bends to the right and deforms, thereby opening the orifice or groove on the diaphragm check valve 15 to allow the second working fluid to pass through. In some embodiments, when the second working fluid or other fluid has a tendency to move from right to left, the diaphragm check valve 15 tends to bend to the left and deform, but due to the restriction of the limiting structure 141, the diaphragm check valve 15 cannot deform, thereby preventing the second working fluid or other fluid from flowing back.

[0060] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
