Description

Technical Field

[0001] This utility model relates to the field of infusion controller technology, specifically to an infusion continuous infusion and dressing change control device. Background Technology

[0002] With the development of science and technology, many intelligent devices have emerged in the medical field. Based on the Internet, they achieve automated intelligent control, bringing great convenience to medical care and patients. Among them, infusion controllers are a relatively advanced intelligent control device with broad market prospects.

[0003] Most existing infusion controllers are clipped onto the infusion tubing or infusion stand. They acquire information about the status of the infusion fluid through a drip rate sensor or other controller. Combined with a control module, warning lights, and a buzzer, they promptly remind medical staff and patients to change the medication or remove the needle when the infusion bottle is empty. This avoids the need for medical staff and patients to constantly monitor the remaining amount of medication in the bottle and prevents backflow of blood caused by failure to change the medication or remove the needle in time after the infusion bottle is empty, thus bringing convenience to infusion.

[0004] In actual intravenous infusion practice, a patient often requires two or more bottles of medication at once. Once one bottle is finished, it needs to be replaced promptly. While existing infusion controllers can alert medical staff and patients when the medication is empty, manual replacement still requires manual intervention. However, many regions currently face strained medical resources and a limited number of medical personnel compared to the large number of patients, especially during epidemics or periods of patient gatherings. Even with the infusion controller's alert, the time for medical staff to reach the patient for replacement is often very limited and rushed. Clearly, infusion controllers that only monitor medication levels and issue alerts are far from sufficient and remain inadequate. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a continuous infusion dressing control device for intravenous infusion, which solves the problems of limited functionality and inconvenience of existing infusion controllers, which can only issue a reminder when the medication is finished, still requiring manual dressing changes.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A continuous infusion dressing control device includes a controller body and a dressing support fixedly connected to the top of the controller body. The back of the controller body is provided with a fixing mechanism for mounting and fixing with the infusion support. A Y-shaped infusion tube is movably snapped onto one side of the controller body. The drip chamber of the Y-shaped infusion tube corresponds to the position of the controller body, and a drip rate sensor corresponding to the position of the drip chamber is fixedly installed on the controller body.

[0008] The dressing change stand has symmetrically arranged positioning tube clamps on the top left and right sides of the front side for movably locking the medicine needle tube of the Y-type infusion tube. The dressing change stand has symmetrically arranged fixed stops on the left and right sides below the two positioning tube clamps on the front side for movably locking the medicine needle tube. The dressing change stand has a horizontally arranged sliding groove on the front side between the two fixed stops. A locking slider is slidably connected in the sliding groove. The locking slider is driven by a sliding drive mechanism provided inside the dressing change stand.

[0009] The drip rate sensor is connected to the control module inside the controller body. The control module is also connected to the gliding drive mechanism and the warning light and buzzer installed on the controller body.

[0010] Preferably, the fixing mechanism includes a fixed clamping flap that is laterally fixed to the back of the controller body and a movable clamping flap disposed on the back of the fixed clamping flap. The fixed clamping flap and the movable clamping flap are movably hinged on one side and movably connected on the other side by a locking bolt.

[0011] Preferably, the locking bolt is a wing bolt, and the inner walls of both the fixed clamp and the movable clamp are fixedly connected with anti-slip rubber pads.

[0012] Preferably, the controller body is provided with a relief groove at the position corresponding to the dripper, the drip rate sensor is installed on the inner side wall of the relief groove, and the side of the controller body is provided with a locking groove for moving and locking the hose at the positions above and below the relief groove. The locking groove is connected to the relief groove and the inner wall of the locking groove is provided with a protrusion for locking the hose.

[0013] Preferably, the inner wall of the fixed stop and both sides of the locking slider are curved surface structures with matching shapes and sizes.

[0014] Preferably, the sliding drive mechanism includes a guide rod and a ball screw horizontally installed inside the dressing holder, and an electric motor installed at the end of the ball screw. The locking slider is slidably connected to the guide rod, and the locking slider and the ball screw are connected by a screw nut.

[0015] Preferably, the control module is connected to the electric motor of the sliding drive mechanism via a signal connection.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This invention, by setting up a fixed stop, a locking slider, and a sliding drive mechanism, allows the control module to drive the locking slider to move left or right via the sliding drive mechanism. This locks the corresponding Y-shaped infusion tube needle with the fixed stop on the left or right side. Therefore, two bottles of medication can be connected at once via the Y-shaped infusion tube. After the medication is finished, in addition to the existing light and sound reminders, the locking slider and fixed stop clamp or release the medication needle, automatically switching the two medication bottles' corresponding medication needles to connect with the drip chamber for continuous infusion and medication change. This allows medical staff to change empty medication bottles during their free time, making medication change more flexible and convenient. It solves the problem that most existing infusion controllers can only issue reminders when the medication is finished, still requiring manual medication change, resulting in limited functionality and inconvenience.
