[0007] The handle is provided with a channel for communicating the top and bottom of the vertical cylinder, when the piston head is at the bottom, the piston head blocks the bottom end of the channel, a flow guide cover is installed on the top of the vertical cylinder through threads, the top of the flow guide cover is provided with an upward opening, and the piston rod penetrates the flow guide cover.
[0008] Preferably, the cross section of the piston rod is designed as a "cross" shape, and the edge of the piston rod is in contact with the inner wall of the flow guide cover.
[0009] Preferably, a limiting ring for limiting the piston head from separating is fixedly installed on the inner wall of the side surface of the vertical cylinder, and the upper surface of the limiting ring is flush with the lower edge of the top opening of the channel.
[0010] Preferably, when the piston head moves to the highest point, the bottom of the piston rod cooperates with the limiting ring, and the lowest point of the drug solution is flush with the upper surface of the limiting ring, so that the drug solution can flow into the channel.
[0011] Preferably, a traction frame is fixedly installed on the top of the piston rod, and the traction frame is designed as a "U" shape.
[0012] In summary, the utility model has the following beneficial technical effects:
[0013] 1. When administering medication to a patient, insert the guide tube into the patient's throat. Slowly lift the piston rod upwards, and the medication will slowly rise in the vertical tube and flow to the top of the channel, then to the bottom of the channel, and finally into the bottom of the vertical tube. The upper and lower parts are connected, allowing the medication to flow smoothly into the patient's body.
[0014] 2. It can be quantitatively fed. The piston rod can be moved up a certain distance, and the medicine liquid that is higher than the top of the channel will enter the channel. The medicine liquid will slowly flow into the mouth over a certain period of time.
[0015] 3. When medication needs to be replenished, a flow guide is installed on the top of the vertical cylinder via threads. The top of the flow guide is open upwards. This design not only makes it convenient for medical staff to quickly pour in the medication, but also ensures the sealing during the operation. In addition, the piston rod passes through the flow guide, making the entire device compact and smooth in operation. Attached Figure Description

[0021] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0022] A critical care medicine drug delivery device, referring to Figures 1-3, including a vertical cylinder 1 and a guide tube at the bottom, the vertical cylinder 1 as the storage and delivery main body of the drug liquid, the drug liquid can be sent into the patient's mouth through the guide tube, the piston rod 2 and the piston head 3 at the bottom are inserted in the vertical cylinder 1, the side of the vertical cylinder 1 is provided with a handle 5 for holding, which can be gripped and forced to facilitate the operation of the piston rod 2 and the piston head 3.
[0023] The top of the piston rod 2 is fixedly installed with a traction frame 4, the traction frame 4 is designed as a "U" type, which provides a comfortable and stable force point for medical staff, facilitating the operation of the piston rod 2, especially in the long or high-intensity drug delivery process, which can effectively reduce the hand fatigue of medical staff and improve the operation efficiency.
[0024] The handle 5 is provided with a channel 6 for communicating the top and bottom of the vertical cylinder 1, when the piston head 3 is located at the bottom, the piston head 3 blocks the bottom end of the channel 6, forming a closed state to prevent the drug liquid from leaking.
[0025] The cross section of the piston rod 2 is designed as a "cross" shape, and the edge of the piston rod 2 is in contact with the inner wall of the flow guide cover 7, so that the piston rod 2 moves up and down on the inner wall of the flow guide cover 7 more stably and is not easy to deviate, and the edge of the piston head 3 is in close contact with the inner wall of the vertical cylinder 1, further enhancing the sealing performance of the device, effectively preventing the drug liquid from leaking and ensuring the accuracy of the drug dose.
[0026] The inner wall of the side of the vertical cylinder 1 is fixedly installed with a limiting ring 8 for limiting the disengagement of the piston head 3, the upper surface of the limiting ring 8 is flush with the lower edge of the top opening of the channel 6, which plays a double protection role, on the one hand, preventing the piston head 3 from disengaging from the vertical cylinder 1 under excessive force or accidental circumstances, causing the drug liquid to leak and the device to be damaged; on the other hand, in cooperation with the channel 6, it provides accurate positioning for the delivery of the drug liquid, ensuring that the drug liquid flows along the predetermined path. When the piston head 3 moves to the highest point, the bottom of the piston rod 2 cooperates with the limiting ring 8, and the lowest point of the drug liquid is flush with the upper surface of the limiting ring 8, ensuring that the drug liquid can flow into the channel 6, realizing the complete delivery of the drug liquid and avoiding residue. In the treatment of critically ill patients, every drop of drug liquid is related to the patient's life. This accurate design can maximize the therapeutic effect of the drug.
[0027] When feeding the patient, the guide tube can be inserted into the throat of the patient's mouth, the piston rod 2 can be slowly lifted upward, the drug liquid slowly flows upward in the vertical cylinder 1 and flows into the top end of the channel 6, then flows to the bottom end of the channel 6 and finally enters the bottom of the vertical cylinder 1, which is connected up and down, and can smoothly flow into the patient's body.
[0028] When feeding, it can be quantitatively fed, the piston rod 2 can be directly moved upward by a distance, the drug liquid higher than the top end of the channel 6 will enter the channel 6, and the drug liquid will slowly flow into the mouth within a certain time.
[0029] When medication needs to be replenished, a flow guide 7 is threaded onto the top of the vertical cylinder 1. The top of the flow guide 7 is open upwards. This design not only makes it convenient for medical staff to quickly pour in the medication, but also ensures the sealing during the operation. Furthermore, the piston rod 2 passes through the flow guide 7, making the entire device compact and smooth in operation.
[0030] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
