Technical Field

[0001] The utility model relates to the technical field of medical supplies, in particular to an injection device with a heating function. Background Art

[0002] The existing infusion bracket has a relatively simple structure design, and the height of the bracket needs to be adjusted manually, which makes it difficult to quickly replace and add medicines. At the same time, in cold weather, the temperature of the medicine in the infusion bottle is usually low. After the low-temperature medicine enters the patient's blood vessels, the patient's body temperature drops, causing vasoconstriction. The cold medicine is injected into the patient's body, which can easily cause physical discomfort to the patient. For this reason, an injection device with a heating function is specially invented. Summary of the invention

[0003] The purpose of the utility model is to provide an injection device with a heating function to solve the problems that the existing infusion bracket has a relatively simple structural design, the height of the bracket is generally adjusted manually, and the temperature of the medicine in the infusion bottle is usually low, which increases the discomfort of the patient during infusion.

DETAILED DESCRIPTION

[0015] The application is described in detail below with reference to the accompanying drawings:

[0016] like Figure 1-3As shown, an injection device with heating function comprises a bottom plate 1, a column 2 is fixedly installed at the middle position of the upper surface of the bottom plate 1, a longitudinal slide 3 is provided on the front side of the column, a connection hole is opened at the middle position of the longitudinal slide, and a medicine bottle 4 is provided on the top of the longitudinal slide. An annular heating resistance wire 5 is provided inside the side wall of the medicine bottle, the heating resistance wire is fixed on the side wall, the annular heating resistance wire can achieve uniform heat distribution, and a micro power supply is provided at the top of the annular heating resistance wire. A thermal pad 6 is provided inside the heating resistance wire, and a thermal insulation pad 7 is provided outside the annular heating resistance wire, and the thermal insulation pad is fitted with the outer wall. A display screen 8 is provided on the outer surface of the medicine bottle, and the lower end of the medicine bottle is open and faces the connection hole of the longitudinal slide. The medicine bottle is divided into a bottle body 41 and a bottle cap 42, and the bottle body and the bottle cap can be connected in any way, such as thread. A temperature sensing element is installed on the side of the thermal pad facing the infusion bottle in the medicine bottle, and the temperature sensing element is connected to the display screen to display the temperature of the medicine in the infusion bottle. The inner thermal pad of the medicine bottle is preferably made of soft material, which can be convenient for better wrapping the infusion bottle. The thermal pad transfers the heat generated by the annular heating resistor to the infusion bottle, thereby heating the liquid medicine in the medicine bottle. The thermal insulation pad is made of PVC material, and the thermal insulation pad reduces heat loss. In actual use, the thermal pad may not be made of soft material. In order to achieve a good heat transfer effect, a water bag with an interlayer can be placed in the thermal pad, and the infusion bottle can be placed in the interlayer of the water bag. The water bag transfers the heat of the heating resistor to the infusion bottle, and the heat is more uniform.

[0017] When in use, place the infusion bottle in the medicine bottle, and the infusion bottle stopper is downward through the connecting hole on the longitudinal slide plate. When infusing, the end of the infusion device is inserted into the stopper of the infusion bottle. Start the resistance wire to heat the liquid medicine. The annular heating resistance wire generates heat and the heat is transferred to the infusion bottle under the action of the thermal pad, thereby heating the liquid medicine in the infusion bottle. Medical staff can observe the temperature in real time through the display screen on the outer surface of the medicine bottle. When it is detected that the temperature reaches the standard, stop heating and then perform normal infusion. This process requires professional medical staff or is operated under the guidance of professional medical staff. Specific different temperatures can be set according to specific drugs. The general principle is that the temperature should not be too high. When the temperature of the liquid medicine rises and the patient feels comfortable, stop heating.

[0018] In the best case, multiple connection holes can be arranged side by side on the longitudinal slide, and multiple medicine bottles and heating resistor wires can also be provided, so that multiple people can use the injection device of the present application together. Alternatively, since each patient has multiple bottles of liquid medicine to be injected every day, one medicine bottle can be used for infusion, and another medicine bottle can be used to preheat the infusion bottle to be infused, which saves time, is convenient to use, and is comfortable for the patient.

[0019] like Figure 1As shown, the column 2 of the present application is provided with three longitudinal grooves 21, and a sliding rod 22 is fixedly installed in the left and right longitudinal grooves, and a threaded rod 23 is movably installed in the middle longitudinal groove through a bearing, and the threaded rod rotates under the drive of a driving motor (which can rotate in both positive and negative directions). A motor seat is fixedly installed in the middle position of the upper surface of the column, and a driving motor 24 is fixedly installed above the motor seat. The motor seat ensures the stability of the driving motor during operation. The top of the threaded rod passes through the upper surface of the column and is connected to the output end of the driving motor. The rear side of the longitudinal slide is sleeved on the threaded rod and the two sliding rods. When adding liquid medicine, the medical staff starts the driving motor, and the output end of the driving motor rotates to drive the threaded rod to rotate. At this time, the longitudinal slide will drive the medicine bottle to move downward, which is convenient for the medical staff to add liquid medicine. In actual use, the threaded rod can be a thicker threaded rod, which can better control the position of the medicine bottle. Or add a pipe clamp to the threaded rod, which is clamped on the threaded rod under the longitudinal slide to prevent the medicine bottle from sliding down.

[0020] A clamping mechanism 9 is provided on the outer periphery of the medicine bottle, and the clamping mechanism 9 includes two longitudinal fixing rods 91, and the two longitudinal fixing rods are respectively fixedly installed on the left and right sides of the medicine bottle, and the top ends of the two longitudinal fixing rods are connected with semicircular fixing rings 92, and the front and rear sides of the two semicircular fixing rings are integrally connected with locking blocks 93, and the two front locking blocks and the two rear locking blocks are connected by bolts to prevent the medicine bottle from falling during use. The inner walls of the two semicircular fixing rings are provided with sponge pads. By setting the sponge pads, the medicine bottle can be prevented from being damaged due to excessive clamping during use, thereby causing economic losses.

[0021] Moving wheels 10 are fixedly installed at the four corners of the lower surface of the base plate to facilitate the movement and transportation of the utility model. At the same time, the outer surface of the moving wheel is processed with patterns to enhance the friction between the moving wheel and the ground, thereby ensuring the stability of the utility model during movement.

[0022] The injection device of the present application is more suitable for use in various departments of medical institutions, especially for patients in operating rooms of anesthesia departments.

[0023] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
