DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-4 , and a handheld pulsed catheter irrigator is provided to solve the problems that it is difficult for medical staff to precisely operate by manually pushing the push rod of the syringe during the catheter irrigation process, and the syringe is prone to rolling and falling during the preparation stage of irrigation. The specific embodiments are as follows:

[0026] Embodiment 1

[0027] The holding shell 10 has a connected open cavity 12 and a closed cavity 11. The open cavity 12 is used to place the syringe, and the closed cavity 11 is used for medical staff to hold.

[0028] On both side walls of the open cavity 12, clamping grooves 121 are respectively provided. The clamping grooves 121 are used to clamp the outer edge of the syringe barrel. That is, after the syringe is placed on the open cavity 12, the outer edge of the syringe barrel is clamped by the clamping grooves 121 to limit the syringe, and the syringe is connected to the catheter.

[0029] The holding shell 10 has a rectangular strip structure, and the bottom of the holding shell 10 has a contact plane. During the preparation stage of irrigation, the syringe is placed on the open cavity 12 and remains stable without rolling.

[0030] The power assembly 20 is located in the closed cavity 11. The power assembly 20 is connected with a moving part 21. The moving part 21 extends into the open cavity 12 and is connected with a pulling and pushing part 22. The pulling and pushing part 22 is used to connect the push handle of the syringe. The power assembly 20 can drive the moving part 21 to continuously extend into the open cavity 12 or contract into the closed cavity 11.

[0031] The power assembly 20 includes a lead screw 201 and a stepping motor 202 that drives the rotation of the lead screw 201. A slider 203 is screwed on the lead screw 201. The moving part 21 is connected with the slider 203. The moving part 21 includes two moving rods 211. The pulling and pushing part 22 includes fixing blocks 221 respectively arranged on the two moving rods 211. Each fixing block 221 is provided with an embedding groove 222.

[0032] The push handle of the syringe can be fitted into the slot 222 of the fixed block 221. Thus, when the stepping motor 202 drives the two moving rods 211 to move, the piston rod of the syringe can be pulled and pushed to move synchronously. When the piston rod is pushed into the cylinder body, the liquid in the syringe is injected into the catheter for flushing. When the piston rod is pulled out of the cylinder body, blood can be aspirated into the catheter to observe whether the catheter is connected to the blood vessel.

[0033] The control panel 30 is installed on the outer wall of the sealed cavity 11. The control panel 30 is electrically connected to the stepping motor 202. The stepping motor 202 works after receiving an electrical pulse signal and is used to control the extension length of the moving part 21 in the open cavity 12. The control panel 30 has a forward button for controlling the moving part 21 to extend into the open cavity 12 and a backward button for controlling the moving part 21 to contract towards the sealed cavity 11. When the medical staff holds the sealed cavity 11, the forward button and the backward button can be pressed according to needs.

[0034] Embodiment 2

[0035] A power source 204 is arranged in the sealed cavity 11. The power source 204 is used to supply power to the stepping motor 202. The power source 204 is preferably a rechargeable battery, and a charging interface is arranged at the tail of the sealed cavity 11, which has good applicability.

[0036] The holding shell 10 is provided with a plurality of transition chamfers on the outer wall of the sealed cavity 11 to improve the comfort of the medical staff's grip.

[0037] An elastic layer 122 is arranged on the inner wall of the card slot 121. The elastic layer 122 is preferably made of rubber material. After the outer edge of the syringe barrel is clamped in the card slot 121, it is contacted by the elastic layer 122, which improves the clamping stability of the outer edge of the syringe barrel.

[0038] A backing plate 123 is arranged on the inner bottom wall of the open cavity 12. The backing plate 123 is used to support the syringe barrel, and an arc surface in contact with the syringe barrel is arranged on the backing plate 123.

[0039] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
