Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a globally heated sheath. Background Art

[0002] Infusion is an important means of clinical treatment of diseases. In cold seasons, the temperature of the room and liquid is relatively low, and the patient's body resistance is reduced. Especially when rescuing critically ill patients, a large amount of liquid needs to be replenished quickly, which causes the patient's local body temperature to drop. Too low a body temperature will cause chills, induce arrhythmia, and cause life-threatening. Therefore, an infusion stand that can heat the infusion tube can, to a certain extent, effectively improve the discomfort caused by low-temperature liquid medicine to patients.

[0003] However, most of the infusion stands currently used to heat the infusion tubes are equipped with a heating device and the heating is achieved by clamping and wrapping the infusion tubes. In order to reduce the size of the device, it is usually only clamped and heated on a portion of the infusion tube, and the entire liquid medicine flows through this section to achieve the purpose of heating the entire liquid medicine.

[0004] However, this heating method wraps the infusion tube for a short length and has a small contact area with the infusion tube, so the heating effect is poor and the heating efficiency is low. Utility Model Content

[0005] The utility model aims to provide a global heating sheath to solve the technical problem in the prior art that the heating effect is poor due to the small contact area with the infusion tube.

[0006] In order to solve the above technical problems, the utility model specifically provides the following technical solutions:

[0008] A heating unit is arranged in the global heating rod body, and the heating unit comprises a wiring harness and a heating plate. The heating plate is arranged in affixed relation to a surface of the arc-shaped heat-conducting groove which is concave toward the inside of the global heating rod body, and the wiring harness connects the heating plate to an external power source.

[0009] As a preferred solution of the utility model, a heat-insulating layer is further provided in the global heating rod body, and the heat-insulating layer is arranged on a side of the heating plate away from the arc-shaped heat-conducting groove, and the heat-insulating layer and the arc-shaped heat-conducting groove clamp the heating plate.

[0010] As a preferred solution of the utility model, a placement piece is provided on the top of the global heating rod body, and the placement piece and the top of the global heating rod body form a hollow placement position for placing an infusion bottle, and the outlet of the infusion bottle in the hollow placement position is arranged colinearly with the top inlet of the arc-shaped heat-conducting groove.

[0011] As a preferred solution of the utility model, the limiting member includes a limiting cover tube which is sleeved on the outside of the global heating rod body, and a strip notch is opened on the limiting cover tube. The trajectory of the strip notch is consistent with the trajectory of the arc-shaped heat-conducting groove, and the width of the strip notch is not less than the width of the arc-shaped heat-conducting groove. The limiting cover tube is rotatably installed on the outer surface of the global heating rod body around the long axis of the global heating rod body.

[0012] As a preferred solution of the utility model, the upper end of the limiting cover cylinder is rotatably connected to the outer wall of the global heating rod body through a slider slot structure, and the lower end of the limiting cover cylinder has a longitudinal telescopic function.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1 to Figure 2 As shown, the utility model provides a globally heated sheath, comprising a globally heated rod body 1 which is completely arranged on the top of an infusion stand, and an arc-shaped heat-conducting groove 2 is provided on the globally heated rod body 1, and the arc-shaped heat-conducting groove 2 extends to the bottom of the globally heated rod body 1, and the opening of the arc-shaped heat-conducting groove 2 is larger than the diameter of the infusion tube, and a limiting member 3 is provided on the arc-shaped heat-conducting groove 2.

[0023] A heating unit 4 is arranged inside the global heating rod body 1. The heating unit 4 includes a wiring harness 5 and a heating plate 6. The heating plate 6 is arranged on the side of the arc-shaped heat-conducting groove 2 that is concave toward the inside of the global heating rod body 1. The wiring harness 5 connects the heating plate 6 to an external power supply.

[0024] In the present device, the global heating rod body 1 can be installed on the top of the infusion rod through a fixed bracket, and then the global heating rod body 1 can be extended downward and arranged in parallel with the infusion rod body. And a gap is left between the infusion rod body and the infusion rod body for the limit cover tube 10 to move. The global heating rod body 1 can specifically be a cylindrical rod body, and an arc-shaped heat-conducting groove 2 for placing the infusion tube is formed on the outer wall of the cylindrical rod body, and a heating plate 6 is arranged on the back of the arc-shaped heat-conducting groove 2. The heating plate 6 is connected to the power supply through a cable. The power supply can be a fixed power supply or a mobile power supply, which can be selected according to different usage scenarios. The heating plate 6 converts electrical energy into heat energy and conducts it into the arc-shaped heat-conducting groove 2, and further transfers the heat energy to the infusion tube through the arc-shaped heat-conducting groove 2, so as to achieve the purpose of heating the liquid medicine in the infusion tube.

[0025] Furthermore, a heat-insulating layer 7 is also provided in the global heating rod body 1 . The heat-insulating layer 7 is arranged on a side of the heating plate 6 away from the arc-shaped heat-conducting groove 2 . The heat-insulating layer 7 and the arc-shaped heat-conducting groove 2 clamp the heating plate 6 .

[0026] By providing a heat-insulating layer 7 on the back of the heating plate 6 , the heat of the heating plate 6 can be prevented from diffusing outward from the back thereof, thereby achieving the purpose of heat-insulating heating and better conducting heat energy to the arc-shaped heat-conducting groove 2 .

[0027] The heat-insulating layer 7 can be made of materials with low thermal conductivity, such as cotton board, rubber board, etc.

[0028] The heating plate 6 and the arc-shaped heat-conducting groove 2 are set as long as possible to wrap as many infusion tubes as possible. In actual production, the arc-shaped heat-conducting groove 2 can be set as a strip or a curved arc, the purpose is to limit all the infusion tubes into the arc-shaped heat-conducting groove 2 for heating.

[0029] Furthermore, a placement piece 8 is provided on the top of the global heating rod body 1, and the placement piece 8 and the top of the global heating rod body 1 form a hollow placement position 9 for placing an infusion bottle, and the outlet of the infusion bottle in the hollow placement position 9 is arranged in line with the top inlet of the arc-shaped heat-conducting groove 2.

[0030] like Figure 2 As shown, specifically, the placement sheet 8 can be configured to be assembled on the left and right to form a bracket shape for supporting the infusion bottle in the bracket, and a hook can also be provided on the placement sheet 8 to facilitate hanging the infusion bag or the infusion bottle with a shell on the outside.

[0031] Moreover, the outlet of the infusion bottle in the hollow placement position 9 is arranged in a colinear line with the top inlet of the arc-shaped heat-conducting groove 2, which can ensure that after the infusion tube is inserted into the infusion bottle, it can enter the arc-shaped heat-conducting groove 2 in a straight line when extending downward from the bottom of the infusion bottle, thereby preventing the infusion tube from bending after entering the arc-shaped heat-conducting groove 2, and the infusion tube from bending when the infusion bottle is accidentally shaken.

[0032] In addition, the limiting member 3 includes a limiting cover tube 10 which is sleeved on the outside of the global heating rod body 1, and a strip notch 11 is opened on the limiting cover tube 10. The trajectory of the strip notch 11 is consistent with the trajectory of the arc-shaped heat-conducting groove 2, and the width of the strip notch 11 is not less than the width of the arc-shaped heat-conducting groove 2. The limiting cover tube 10 is rotatably installed on the outer surface of the global heating rod body 1 around the long axis of the global heating rod body 1.

[0033] The function of the limiting cover barrel 10 is to limit the infusion tube entering the arc-shaped heat-conducting groove 2, and prevent it from falling out of the arc-shaped heat-conducting groove 2 during normal use. However, there are many limiting members 3 that can achieve this function, among which a single limiting clip or limiting buckle is widely used in the prior art. Then, this device uses this more preferred embodiment, which can facilitate the patient's infusion technology. When the infusion tube is removed from the infusion stand, it can be quickly removed from the limiting cover barrel 10 at one time, without the need to open the limiting clip or limiting buckle one by one, thereby improving the practical efficiency of the device.

[0034] Specifically, when the infusion tube needs to be taken out from the limiting cover tube 10, it is only necessary to rotate the limiting cover tube 10 to align the strip notch 11 thereon with the arc-shaped heat-conducting groove 2, and the infusion tube can be taken out at one time.

[0035] Furthermore, the upper end of the limiting cover tube 10 is rotatably connected to the outer wall of the global heating rod body 1 through the slider slot structure 12, and the lower end of the limiting cover tube 10 has the function of longitudinal extension.

[0036] The slider slot structure 12 can specifically be an annular slot opened on the outer wall of the global heating rod body 1, the annular slot is not connected to the arc-shaped heat-conducting slot, and a slider is provided on the inner wall of the limiting cover barrel 10, and the axial rotation of the limiting cover barrel 10 is realized by embedding the slider in the annular slot. Furthermore, the lower end of the limiting cover barrel 10 has the function of longitudinal extension and contraction, which can ensure that the bottom of the limiting cover barrel 10 can move upward, thereby exposing more infusion tubes. When in use, when the patient's arm for infusion needs to move, the bottom end of the limiting cover barrel 10 is raised upward at this time, so that a part of the infusion tube can be exposed, which is more convenient for the patient's practical use. Specifically, there are many ways in the prior art for this longitudinal extension structure, such as a multi-section interference fit method similar to a fishing rod, a structure similar to an umbrella rib that uses lock beads for extension and contraction, or a structure that uses a magnetic suction sheet for magnetic adsorption to complete extension and contraction, etc.

[0037] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
