Description

Technical Field

[0001] The utility model relates to the technical field related to medical devices, in particular to a warm surgical infusion tube. Background Art

[0002] Intraoperative hypothermia is a common complication during surgery, especially during long operations, major operations, and when the elderly and children are undergoing operations. Once hypothermia occurs during surgery, it will cause some symptoms in the patient's body, such as postoperative chills, postoperative wound infection, cardiac tube complications, etc., which will have some adverse effects on the patient's postoperative recovery process. Therefore, the existing infusion needs to warm the liquid. On the one hand, it meets the patient's needs for these liquids, and on the other hand, it also reduces the possibility of intraoperative hypothermia. Therefore, during the operation, maintaining the patient's body temperature is also a critical step.

[0003] The existing disposable infusion heating pad device heats the infusion tube. Due to its low cost, it is widely used. However, when the heating pad is used, except for the part that is folded in half to wrap the infusion tube, the other parts are completely exposed to the air, resulting in rapid heat loss. During a long infusion process, the temperature will gradually decrease, resulting in poor heating effect.

[0004] The existing electrically controlled infusion heating device, when in use, generates heat by energizing the heating plate to heat the infusion tube. Although the heating temperature can be effectively maintained constant to a certain extent, a partition is generally provided between the heating unit (heating wire) and the infusion tube to block the heating. However, the temperature of the infusion tube heated by the heating unit is poor, and the problem of the temperature being set too high affecting the efficacy of the drug may occur.

DETAILED DESCRIPTION

[0025] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0026] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0027] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0028] See also Figures 1 to 5 In an embodiment of the utility model, a warm surgical infusion tube includes a base 1, a reaction tank 3, a circular cover 4, an intermittent pump gas component, an annular receiving member 7 and an elastic sealing component.

[0029] It includes the base 1 and the reaction tank 3 installed on the base 1, the circular cover 4 is detachably installed on the reaction tank 3, and a plurality of through grooves equidistantly arranged are formed on the circular cover 4, the intermittent pump air assembly is installed on the base 1 and communicated with the inner side of the reaction tank 3, and is used for intermittently conveying external air into the reaction tank 3; the annular receiving member 7 is installed on the circular cover 4, and an annular groove is formed on the inner side of the annular receiving member 7, and the annular groove and the outer wall of the circular cover 4 form an annular cavity, and the through groove communicates the annular cavity and the inner side of the circular cover 4, and a plurality of through holes are also provided on the annular receiving member 7; the elastic sealing assembly is installed on the inner side of the circular cover 4, and is used for driving the elastic sealing assembly to release the blocking state when the pressure in the reaction tank 3 increases, so that the annular cavity is communicated with the inner side of the reaction tank 3.

[0030] Among them, it should be noted that: a temperature display 2, a temperature sensor and a buzzer are fixedly installed on the base 1, and the temperature sensor is fixedly connected to the reaction tank 3. The temperature sensor can detect the temperature in the reaction tank 3 and transmit it to the temperature display 2. The buzzer sets the alarm value and the limit value. When the alarm value is exceeded, the buzzer sounds for a long time. When the temperature exceeds the limit value, the closer the temperature is to the alarm value, the faster the buzzer sounds. Therefore, when the temperature in the reaction tank 3 rises above 37°C, the buzzer alarms, so as to promptly remind medical staff to drive the intermittent pump gas component to stop working.

[0031] The reaction tank 3 generates heat by utilizing the heat released by the iron oxidation reaction. Each infusion is heated by replacing heating materials such as iron powder and activated carbon in the reaction tank 3. These chemical materials solidify into blocks after the reaction, and can be quickly and easily replaced by opening the circular cover 4.

[0032] In this embodiment, the device is placed on the infusion pole through the annular groove on the base 1, the infusion tube is wound around the annular receiving member 7, and the intermittent pump air component is started to work, so that air enters the reaction tank 3, and the oxygen in the air contacts the iron powder to react and release heat, the temperature in the reaction tank 3 rises, the pressure increases, and the elastic blocking component is driven to release the blocking work, so that the hot air in the reaction tank 3 enters the annular cavity through the groove on the circular cover 4, and after entering the annular cavity, the heat is transferred to the part of the annular receiving member 7, and then the infusion tube wound around the annular receiving member 7 is heated through the through hole. The temperature of the infusion is generally between 37-38°C, but not higher than 39°C. The specific transfusion body temperature is determined according to the doctor's requirements. Once the temperature exceeds 39°C, the buzzer alarm can remind the medical staff to cut off the power supply in time, effectively increasing the liquid temperature when infusing the patient, preventing hypothermia and causing human discomfort and other symptoms.

[0033] Please refer to Figure 5 In this embodiment, the intermittent pump gas assembly includes a sleeve 12, a support plate 16 is fixedly mounted on the base 1, a support frame 9 is fixedly mounted on the support plate 16, the sleeve 12 is fixedly mounted on the support plate 16 through a hoop, an inlet pipe 14 and an outlet pipe 15 are fixedly connected to the sleeve 12, one end of the inlet pipe 14 passes through the sleeve 12, and the other end is placed in the air for absorbing oxygen, one end of the outlet pipe 15 passes through the reaction tank 3, and the other end passes through the sleeve 12, and the inner wall of the sleeve 12 abuts against the second piston 13;

[0034] It also includes a moving driving member, which is installed on the supporting frame 9 and connected to the second piston 13 .

[0035] Please refer to Figure 5 In this embodiment, the mobile driving member includes a turntable 10, the rotating shaft of the turntable 10 is rotatably mounted on the support frame 9, a connecting rod 11 is rotatably mounted at an eccentric position of the turntable 10, and one end of the connecting rod 11 away from the turntable 10 is rotatably connected to the second piston 13; a motor 8 is fixedly mounted on the support frame 9, and the output shaft of the motor 8 is fixedly connected to the rotating shaft of the turntable 10.

[0036] The driving motor 8 works, and the motor 8 drives the output shaft to rotate. When the output shaft rotates, it drives the rotating shaft of the turntable 10 to rotate, and the turntable 10 rotates accordingly. When the turntable 10 rotates, the reciprocating movement of the second piston 13 is realized by the connecting rod 11. A one-way valve is provided in the inlet pipe 14 and the outlet pipe 15. The one-way valve gas in the inlet pipe 14 can only enter but not exit, and the one-way valve gas in the outlet pipe 15 can only exit but not enter. When the turntable 10 drives the second piston 13 to move toward one side of the turntable 10, the pressure in the sleeve 12 increases, so that the outside air enters the sleeve 12. When the turntable 10 drives the second piston 13 to move toward the side away from the turntable 10, the pressure in the sleeve 12 increases, so that the air in the sleeve 12 enters the reaction tank 3 through the outlet pipe 15, contacts with the heat-generating material in the reaction tank 3 to react and release heat, and the reciprocating movement of the second piston 13 realizes the circulation of the air in the reaction tank 3, thereby controlling the air temperature in the reaction tank 3.

[0037] In another implementation manner of this embodiment, a cylinder is fixedly mounted on the support plate 16 , a fixed end of the cylinder is fixedly mounted on the support plate 16 , and a movable end of the cylinder is rotatably connected to the second piston 13 .

[0038] Of course, in this embodiment, the reciprocating movement of the second piston 13 is not limited to the crank slider device, and the reciprocating movement of the second piston 13 is achieved by a cylinder. The cylinder method belongs to a conventional design and is not specifically limited in this embodiment.

[0039] Please refer to Figure 3 In this embodiment, the elastic sealing assembly includes a first piston 6, which abuts against the inner wall of the circular cover 4. One end of the first piston 6 abuts against a spring 5, and one end of the spring 5 away from the first piston 6 is fixedly connected to the circular cover 4.

[0040] When the temperature in the reaction tank 3 rises, the pressure increases, driving the first piston 6 to contact the blocking state, and the first piston 6 moves toward one side of the spring 5. The hot air in the reaction tank 3 enters the annular cavity through the through groove on the circular cover 4, and part of the heat is transferred to the annular receiving part 7, and part of the hot air goes out through the through hole on the annular receiving part 7, thereby heating the infusion tube wound on the annular receiving part 7. The infusion tube is wound on the annular receiving part 7 in a spiral manner. On the one hand, it is to increase the contact area with the annular receiving part 7, increase the heating time of the liquid in the infusion tube, and accelerate the temperature rise of the liquid in the infusion tube. On the other hand, it is to install the temperature of the infusion tube on the annular receiving part 7 to prevent the infusion tube from falling.

[0041] Please refer to Figure 3In this embodiment, an external thread is formed on the circular cover 4, the circular cover 4 is threadedly connected to the reaction tank 3, a sealing plate is formed on the circular cover 4, and the first piston 6 abuts against the sealing plate when it is not deformed.

[0042] The circular cover 4 is detachable and installable from the reaction tank 3. The circular cover 4 can be fixed to or detached from the reaction tank 3 by rotating, thereby realizing convenient replacement of the heating material in the reaction tank 3. The present embodiment adopts a one-time heating method. Before each infusion, the heating pack containing the heating material needs to be placed in the reaction tank 3, and then the circular cover 4 is rotated and threadedly installed together with the reaction tank 3, which reduces the burden on the work of medical staff and is highly practical.

[0043] Please refer to Figure 3 and Figure 4 In this embodiment, a semi-arc groove is formed outside the annular receiving member 7, and a placement space is formed on the semi-arc groove.

[0044] The semi-arc groove provided on the annular receiving member 7 provides a stable placement space for the infusion tube, preventing the infusion tube from sliding down under the action of its own gravity, resulting in the inability to heat the liquid in the infusion tube, causing trouble to the work of medical staff.

[0045] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
