Description
Technical Field
[0001] The utility model relates to the technical field of electronic injectors, in particular to an electronic injector which is convenient for replacing a needle. Background Art
[0002] An electronic syringe is a type of automatic injector, a device that can automatically inject drugs into the patient's body through electronic control to ensure the accuracy and precision of the drug dosage, which may be very convenient for some patients who need regular injections.
[0003] The needle of an electronic syringe needs to be replaced when it is used. When replacing the needle of an existing electronic syringe, the staff generally holds the needle in one hand and the syringe in the other hand, and then connects the two by inserting them. The syringe and the needle are connected by friction, which requires the staff to apply a lot of pressure to the two during the connection process to ensure a smooth connection. The need to apply a lot of force to connect the needle and the syringe may increase the risk of accidental punctures or injuries. The staff may accidentally stab themselves when applying pressure, especially if control is lost during the operation or an unexpected situation occurs, making it impossible to easily replace the needle.
[0004] Therefore, it is necessary to design an electronic syringe that is easy to replace the needle to solve the above problems. Utility Model Content
[0005] The utility model aims to solve the shortcomings in the prior art and provides an electronic syringe which is convenient for replacing the needle.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0020] Reference Figure 1-3 , an electronic syringe that is easy to replace a needle, includes a frame 1, an electronic drive module 2 is installed on the frame 1, the specific structure and working principle of the electronic drive module 2 are not the innovative part of the present technical solution, and are not shown in the figure, and will not be described in detail here. A syringe 3 is connected to the frame 1, and the electronic drive module 2 is connected to the syringe 3. A needle tube connector 4 is provided at the bottom end of the syringe 3, and a connecting end 5 is connected to the needle tube connector 4. A guide structure is commonly provided on the needle tube connector 4 and the connecting end 5. Under the action of the guide structure, when the needle tube connector 4 is inserted into the connecting end 5, the two card slots 73 are just opposite to the two card blocks 72. The specific structure and working principle of the guide structure are not the innovative part of the present technical solution, and are not shown in the figure, and will not be described in detail here. A needle 6 is fixed on the connecting end 5.
[0021] The needle tube connector 4 is connected to the connecting end 5 through a connecting assembly, which includes an annular airbag 71, two clamping blocks 72 and two clamping grooves 73. The annular airbag 71 is fixed on the needle tube connector 4, and the two clamping blocks 72 are fixed on the outer peripheral surface of the annular airbag 71. The two clamping grooves 73 are both opened on the inner surface of the connecting end 5. The cross-section of the clamping block 72 is a trapezoidal structure, and the shape of the clamping groove 73 is adapted to the clamping block 72, that is, the end of the clamping block 72 away from the annular airbag 71 is smaller than the end close to the annular airbag 71, and the shape of the clamping groove 73 is adapted to the clamping block 72. When connecting the needle tube connector 4 and the connecting end 5, the small end of the clamping block 72 will first be inserted into the large mouth of the clamping groove 73. This design is conducive to the smooth insertion of the clamping block 72 into the clamping groove 73.
[0022] A control assembly is provided on the frame 1, and the control assembly includes a sealing cylinder 81, a sliding plug 82, a connecting rod 83, a spring 84, a push block 85 and an air pipe 86. The sealing cylinder 81 is fixed to the side of the frame 1, and the sliding plug 82 is sealingly and slidably connected to the inner surface of the sealing cylinder 81. One end of the connecting rod 83 is fixedly connected to the sliding plug 82, and the other end extends to the outside of the sealing cylinder 81. One end of the spring 84 is connected to the inner surface of the sealing cylinder 81, and the other end is connected to the sliding plug 82. The push block 85 is fixed to one end of the connecting rod 83 located outside the sealing cylinder 81. The surface of the push block 85 is provided with anti-slip grooves, and the side of the push block 85 is in contact with the side of the frame 1. Such a setting can ensure the stability of the push block 85 during its movement. One end of the air pipe 86 is connected to the sealing cylinder 81, and the other end is connected to the annular airbag 71.
[0023] The specific working principle of the utility model is as follows:
[0024] When the electronic syringe for replacing needles proposed by the utility model is used, when the needle 6 is connected, the staff manually pushes the push block 85, so that the push block 85 moves in the direction away from the sealing tube 81. At this time, the push block 85 can push the sliding plug 82 through the connecting rod 83, so that the sliding plug 82 moves inside the sealing tube 81. When the sliding plug 82 moves, it can extract the air in the annular airbag 71 to shrink the annular airbag 71, which makes the two blocks 72 close to each other. Then, the staff inserts the needle tube connector 4 into the connecting end 5. The needle tube connector 4 and the connecting end 5 are jointly provided with a guide structure. Under the action of the guide structure, when the needle tube connector 4 is inserted into the connecting end 5, the two card grooves 73 are just opposite to the two blocks 72. The specific structure and working principle of the guide structure will not be described in detail. This is the innovative part of the technical solution, which is not shown in the figure and will not be described in detail here. When the two are connected, the staff releases the push block 85, and the push block 85 will be reset under the action of the spring 84, which makes the slide plug 82 move in the opposite direction in the sealing tube 81. When the slide plug 82 is reset, the air in the sealing tube 81 can be pressed into the interior of the annular airbag 71 through the air pipe 86, so that the annular airbag 71 is inflated. When the annular airbag 71 is inflated, it can drive the two clamping blocks 72 to move until the two clamping blocks 72 are respectively inserted into the two clamping grooves 73, which can fix the needle tube connector 4 and the connecting end 5. The connection process is convenient and quick. The staff only needs to control the position of the push block 85 to achieve the connection of the needle, and the staff does not need to push the needle tube connector 4 and the connecting end 5 with force.
[0025] It is worth noting that the cross-section of the block 72 is a trapezoidal structure, that is, the end of the block 72 away from the annular airbag 71 is smaller than the end close to the annular airbag 71, and the shape of the slot 73 is adapted to the block 72. When connecting the needle tube connector 4 and the connecting end 5, the small end of the block 72 will first be inserted into the large mouth of the slot 73. This design is conducive to the smooth insertion of the block 72 into the slot 73.
[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
