Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an infusion set with a heating structure. Background Art

[0002] Infusion pump, or infusion pump, is a medical device for infusion. The traditional infusion method is to hang the liquid in the bottle or infusion bag at a high place, and use gravity to make the liquid flow into the vein through the infusion tube. The flow rate is manually adjusted by the clamp placed on the tube.

[0003] After searching, a utility model with Chinese patent announcement number CN210813060U discloses a heated infusion set, including a bottle stopper puncture device, an infusion tube and a venous puncture device, a flow rate regulator is sleeved on the outer side of the infusion tube, the outer wall of the infusion tube is slidably connected to the lower box body through a guide groove, insulation sheets are fixedly installed on both vertical sides of the guide groove, and a heat conductive sheet is fixedly installed on the side of the insulation sheet away from the guide groove.

[0004] The heating portion of the above device is linear. If the ambient temperature is low, the heating effect can only be achieved by slowing down the flow rate of the medicine. Therefore, the duration of the drip will be greatly extended, or the overall length of the device will need to be lengthened. Therefore, the movement of the infusion tube will also be affected, and there is room for improvement. Utility Model Content

[0005] The purpose of the utility model is to provide an infusion set with a heating structure to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an infusion pump with a heating structure, comprising an infusion pump body, characterized in that: a heating box is sleeved on the outside of the infusion pump body, an electric heating tube is arranged inside the heating box, a sleeve assembly is installed inside the heating box, the sleeve assembly comprises two mounting blocks arranged at the bottom of the outer wall of one side of the heating box, the two mounting blocks are rotatably connected with the same bidirectional screw, and the threads at both ends of the bidirectional screw have the same parameters except for the opposite rotation directions, a mounting plate is respectively threadedly sleeved on the threads at both ends of the bidirectional screw, the two mounting plates are both in contact with the inner wall of the bottom of the heating box, a knob is rotatably connected to the outer wall of one side of the mounting blocks, the knob and one end of the bidirectional screw are coaxially fixed, and the top outer walls of the two mounting plates are fixedly connected with a plurality of equidistantly distributed bosses.

[0007] This allows longer infusion tubes to be stored in the heating box, thereby ensuring that the medicine is heated for a longer time, and the length of the infusion tube in the heating box can be adjusted according to the external environment, making the device more adaptable. If the outside temperature is lower, it is only necessary to drive the two-way screw to rotate between the two mounting blocks through the knob. Since the two mounting plates are in contact with the inner wall of the heating box, the two mounting plates will be driven away from each other by the two-way screw, and the length of the infusion tube restricted by the sheath component can be longer. Subsequently, the infusion device body is wrapped around the multiple bosses on the top of the two mounting plates to ensure that the infusion tube is coiled in the heating box.

[0008] As a further preferred embodiment of the present technical solution, an elastic band is provided at the bottom of the outer walls on both sides of the heating box, and a clamping head and a clamping sleeve are respectively provided at the ends of the two elastic bands close to each other, and the clamping head can be slidably inserted in the clamping sleeve.

[0009] Place the heating box on the top of the patient's arm, then wrap the two elastic bands around the outside of the patient's arm, and then slide the clamp at one end of the elastic band into the clamp at one end of the other elastic band to restrict the two elastic bands into a whole, thereby ensuring that the needle will not fall out due to the pulling of the infusion tube when the patient's arm moves, further increasing the safety of the device.

[0010] As a further preferred embodiment of the technical solution, the two mounting plates are slidably connected with two reinforcement rods, and the two ends of the two reinforcement rods are respectively fixedly connected to the inner walls on both sides of the heating box.

[0011] As a further preferred embodiment of the present technical solution, a magnetic strip is provided on one side of the top outer wall of the heating box body, and another magnetic strip is provided on one side of the bottom outer wall of the heating box cover, and the two magnetic strips can be adsorbed together.

[0012] As a further preferred embodiment of the present technical solution, the diameter of the knob is greater than the diameter of the bidirectional screw.

[0013] As a further preferred embodiment of the present technical solution, the shell of the heating box is made of heat-insulating material.

[0014] The utility model provides an infusion set with a heating structure, which has the following beneficial effects:

[0015] (1) The utility model provides a sleeve assembly so that a longer infusion tube can be stored in the heating box, thereby ensuring that the medicine is heated for a longer time, and can adjust the length of the infusion tube in the heating box according to the external environment, making the device more adaptable. If the outside temperature is lower, it is only necessary to drive the bidirectional screw rod to rotate between the two mounting blocks through the knob. Since the two mounting plates are in contact with the inner wall of the heating box, the two mounting plates will be driven away from each other by the bidirectional screw rod, and the length of the infusion tube restricted by the sleeve assembly can be longer. Then, the infusion device body is wrapped around the multiple protrusions on the top of the two mounting plates to ensure that the infusion tube is coiled in the heating box.

[0016] (2) The utility model places the heating box on the top of the patient's arm by arranging an elastic band, a clamp and a sleeve, and then makes the two elastic bands surround the outside of the patient's arm. Then, the clamp at one end of the elastic band is slidably inserted into the sleeve at one end of the other elastic band, so that the two elastic bands can be restricted into a whole, thereby ensuring that the needle will not fall out due to the pulling of the infusion tube when the patient's arm moves, thereby further increasing the safety of the device.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] The utility model provides a technical solution: Figure 2 and Figure 4As shown, in the present embodiment, an infusion pump with a heating structure comprises an infusion pump body 1, characterized in that: a heating box 2 is sleeved on the outside of the infusion pump body 1, an electric heating tube is arranged inside the heating box 2, a sleeve assembly 7 is installed inside the heating box 2, the sleeve assembly 7 comprises two mounting blocks 701 arranged at the bottom of the outer wall of one side of the heating box 2, the two mounting blocks 701 are rotatably connected with the same bidirectional screw 702, and the threads at both ends of the bidirectional screw 702 have the same parameters except for the opposite rotation directions, a mounting plate 703 is respectively threadedly sleeved on the threads at both ends of the bidirectional screw 702, the two mounting plates 703 are both in contact with the inner wall at the bottom of the heating box 2, one of the mounting blocks 701 is rotatably connected to the outer wall on one side with a knob 706, the knob 706 and one end of the bidirectional screw 702 are coaxially fixed, and the top outer walls of the two mounting plates 703 are fixedly connected with a plurality of equidistantly distributed bosses 704.

[0024] If the outside temperature is lower, it is only necessary to drive the bidirectional screw rod 702 to rotate between the two mounting blocks 701 through the knob 706. Since the two mounting plates 703 are in contact with the inner wall of the heating box 2, the two mounting plates 703 will be driven by the bidirectional screw rod 702 to move away from each other, and the length of the infusion tube limited by the sleeve component 7 can be longer. Then, the infusion device body 1 is wrapped around the multiple protrusions 704 on the top of the two mounting plates 703 to ensure that the infusion tube is coiled in the heating box 2, and the electric heating tube inside the heating box 2 is started. The heat emitted by the electric heating tube can heat the infusion tube inside the heating box 2.

[0025] like Figure 2 and Figure 3 As shown, an elastic band 4 is provided at the bottom of the outer walls on both sides of the heating box 2, and a clamping head 5 and a clamping sleeve 6 are respectively provided at the ends of the two elastic bands 4 close to each other, and the clamping head 5 can be slidably inserted in the clamping sleeve 6.

[0026] Place the heating box 2 on the top of the patient's arm, and then make the two elastic bands 4 wrap around the outside of the patient's arm, and then slide the clamp 5 at one end of the elastic band 4 into the clamping sleeve 6 at one end of the other elastic band 4, so that the two elastic bands 4 can be restricted into a whole, thereby ensuring that the needle will not fall out due to the pulling of the infusion tube when the patient's arm moves, thereby further increasing the safety of the device.

[0027] like Figure 2 As shown, two mounting plates 703 are slidably plugged with two reinforcing rods 705, and both ends of the two reinforcing rods 705 are respectively fixedly connected to the inner walls on both sides of the heating box 2 to ensure that the sliding process of the mounting plates 703 is more stable.

[0028] like Figure 2As shown, a magnetic strip 3 is provided on one side of the top outer wall of the heating box 2, and another magnetic strip 3 is provided on one side of the bottom outer wall of the cover of the heating box 2. The two magnetic strips 3 can be adsorbed together, which can increase the connection effect between the box body and the cover and make the opening and closing process more convenient.

[0029] like Figure 1 and Figure 2 As shown, the diameter of the knob 706 is greater than the diameter of the bidirectional screw rod 702, which can increase the transmission force arm and ensure that the driving process is easier.

[0030] like Figure 1 and Figure 2 As shown, the outer shell of the heating box 2 is made of heat-insulating material to prevent the heat emitted by the electric heating tube in the heating box 2 from being transferred to the patient's arm through the outer shell.

[0031] The utility model provides an infusion set with a heating structure, and the specific working principle is as follows:

[0032] When the device is working, if the outside temperature is lower, it is only necessary to drive the bidirectional screw rod 702 to rotate between the two mounting blocks 701 through the knob 706. Since the two mounting plates 703 are in contact with the inner wall of the heating box 2, the two mounting plates 703 will be driven by the bidirectional screw rod 702 to move away from each other, and the length of the infusion tube restricted by the sleeve component 7 can also be longer. Then, the infusion device body 1 is wrapped around the multiple protrusions 704 on the top of the two mounting plates 703 to ensure that the infusion tube is coiled in the heating box 2, and then the electric heating tube inside the heating box 2 is started. The heat emitted by the electric heating tube can heat the infusion tube inside the heating box 2, and then the heating box 2 is placed on the top of the patient's arm, and then the two elastic bands 4 are wrapped around the outside of the patient's arm, and then the clamp 5 at one end of the elastic band 4 is slidably inserted into the clamping sleeve 6 at one end of the other elastic band 4, so that the two elastic bands 4 can be restricted into a whole, thereby ensuring that the needle will not fall off due to the pulling of the infusion tube when the patient's arm moves, further increasing the safety of the device.

[0033] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
