Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a myocardial protective fluid cooling device for surgery. Background Art

[0002] During cardiac surgery, the heart vessels need to be blocked, and the muscle cells of the heart are prone to lose their activity after ischemia. Therefore, myocardial protective fluid needs to be infused to maintain the activity of human heart muscle cells and avoid ischemic necrosis of myocardial cells. The ambient temperature of the myocardial protective fluid is between 2°C and 4°C. Therefore, the myocardial protective fluid needs to be adjusted to a suitable temperature before being injected into the human body. In order to adjust the temperature of the myocardial protective fluid, a corresponding cooling device is often installed outside the myocardial protective fluid input pipeline. However, since the temperature of the cooling device is lower than the room temperature, the outside of the container is very easy to condense and frost under the effect of the temperature difference. After the frost on the container melts, it will cause the operating room environment to be humid, affecting the surgical effect. For this reason, medical staff will install a sleeve on the outside of the container to collect the moisture generated during the defrosting process through the sleeve. The moisture between the outer wall of the container and the sleeve increases the suction between the container and the sleeve, making it difficult to remove the container from the sleeve, affecting the replacement and cleaning process of the container. Summary of the invention

DETAILED DESCRIPTION

[0021] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and are not to be construed as limitations of the present invention. On the contrary, embodiments of the present invention include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0022] like Figures 1 to 5 As shown, the present invention provides a myocardial protective liquid cooling device 100 for surgery, comprising an outer barrel 10, an inner barrel 20 accommodated in the outer barrel 10, and a barrel cover 30 provided on the outer barrel 10 in cooperation with the barrel cover. The inner barrel 20 is placed in the outer barrel 10, the inner barrel 20 and the side wall of the outer barrel 10 are fitted together, the barrel cover 30 is provided on the port of the outer barrel 10 in cooperation with the barrel cover 30, and the inner barrel 20 can be fixed in the outer barrel 10 under the blocking of the barrel cover 30, and when the barrel cover 30 and the outer barrel 10 are installed in place, the top of the inner barrel 20 is abutted against the barrel cover 30.

[0023] The inner barrel 20 is a hollow cylindrical structure with an opening at the upper end. An interlayer 130 is provided in the wall of the inner barrel 20. A coil 131 is provided in the interlayer 130. The inner cavity of the inner barrel 20 is filled with ice cubes. Myocardial protection fluid is buried in the ice cubes. Cooling water circulates in the coil 131. When in use, the cooling water flows into the coil 131 through the outside of the inner barrel 20, so as to regulate the temperature of the inner barrel 20. Specifically, when the temperature of the ice cubes in the inner barrel 20 increases, the cooling water can circulate in the coil 131, so as to cool the inner barrel 20, and further cool the myocardial protection fluid in the inner barrel 20, so as to ensure that the myocardial protection fluid is always maintained in the range of 2°C-4°C.

[0024] In this embodiment, an inlet pipe 310 and an outlet pipe 320 are fixedly mounted on the barrel cover 30, and both ends of the coil 131 extend to the outside of the barrel cover 30 after passing through the inlet pipe 310 and the outlet pipe 320 respectively. In an embodiment not shown, both ends of the coil 131 extending to the outside of the barrel cover are connected to a cooling water tank (not shown), which is used to provide cooling water. A circulating water pump is installed on the coil 131 so that the cooling water can circulate in the coil 131.

[0025] It can be understood that in other embodiments not shown, the inlet pipe 310 and the outlet pipe 320 can also be omitted. In this case, a U-shaped notch is provided on the side wall of the inner barrel 20, the U-shaped notch is located at the top of the side wall of the inner barrel 20, and the U-shaped notch passes through the upper end surface of the inner barrel 20, so that the two ends of the coil 131 pass through the U-shaped notch and extend to the outside of the inner barrel 20. Correspondingly, a through groove aligned with the U-shaped notch is provided on the side wall of the barrel cover 30, and the ends of the coil 131 pass through the U-shaped notch and the through groove in sequence and extend to the outside of the barrel cover 30. At the same time, the barrel cover 30 is connected to the outer barrel 10 by a buckle. When in use, the medical staff can install the barrel cover 30 on the outer barrel 10 by pressing it down, and can remove it from the outer barrel 10 by lifting it up.

[0026] An ejection assembly 40 is also provided in the outer barrel 10, which can push the inner barrel 20 so that the inner barrel 20 moves relative to the outer barrel 10, thereby pushing the inner barrel 20 out of the outer barrel 10, so that the inner barrel 20 and the outer barrel 20 are separated, making it easy to take out the inner barrel 20 from the outer barrel 10.

[0027] Specifically, the outer barrel 10 is a hollow cylindrical structure with an opening at the upper end. A plurality of chambers are provided in the wall of the outer barrel 10 in an inner and outer surrounding manner, so that the outer barrel 10 as a whole is a multi-layer cylindrical structure, wherein the outermost chamber along the radial direction of the outer barrel 10 is filled with an insulation member, which may be cotton wool or carbon fiber or other insulation materials. The innermost chamber along the radial direction is a vacuum interlayer. Through the insulation of the vacuum interlayer and the insulation member, the internal temperature of the inner barrel 20 can be guaranteed to be not affected by external heat to the greatest extent, thereby reducing the amount of frost formed on the side wall of the inner barrel 20.

[0028] like Figure 3 As shown, a connecting column 110 is protrudingly provided at the middle position of the innermost layer of the outer barrel 10 , and the connecting column 110 is arranged along the axial direction of the outer barrel 10 .

[0029] The upper end surface of the connecting column 110 is recessed downward along the axial direction of the connecting column 110 to form an ejection hole 111, and a push cover 112 is pluggably provided in the ejection hole 111. The push cover 112 covers the ejection hole 111, and a cover column 210 corresponding to the connecting column 110 is protruded on the bottom wall of the inner barrel 20, and the cover column 210 can be movably covered on the push cover 112 so that the bottom wall of the inner barrel 20 is abutted against the push cover 112.

[0030] The ejection assembly 40 includes an elastic member 410, a magnetic member 420, and an electromagnet 430 disposed in the ejection hole 111. The elastic member 410 is preferably a spring, and the two ends of the elastic member 410 are respectively fixedly connected to the bottom wall of the ejection hole 111 and the top wall of the push cover 112, the magnetic member 420 includes a mounting base 421 fixedly mounted on the push cover 112 and a permanent magnet 422 fixed to the bottom of the mounting base 421, and the electromagnet 430 is mounted on the bottom wall of the ejection hole 111, the electromagnet 430 corresponds to the permanent magnet 422, and the electromagnet 430 and the magnetic member 420 are both disposed in the elastic member 410. Specifically, during normal use, the electromagnet 430 loses power and does not generate magnetism, so it will not attract the magnetic element 420. At the same time, the elastic element 410 is compressed. When medical staff need to take the inner barrel 20 out of the outer barrel 10, they only need to energize the electromagnet 430. At this time, the magnetic poles of the opposite ends of the electromagnet 430 and the magnetic element 420 are the same, so that the two repel each other. In this way, the push cover 112 pushes the inner barrel 20 upward under the repulsive force and the elastic force of the elastic element 410, thereby facilitating the inner barrel 20 to be taken out of the outer barrel 10.

[0031] Preferably, a concave wrench cavity 220 is also provided on the inner barrel 20 , and medical personnel can pull the inner barrel 20 out of the outer barrel 10 through the wrench cavity 220 , further facilitating the removal of the inner barrel 20 from the outer barrel 10 .

[0032] Preferably, the outer barrel 10 is also provided with power supply columns 120 on both sides of the connecting column 110, and a push switch (not shown) is provided on the bottom wall of the inner barrel 20 at a position corresponding to the power supply column 120, and a waterproof plastic film is provided on the bottom wall of the inner barrel 20, which is used to cover the push switch, and can isolate the push switch from the outside world without affecting the pressing and ejection of the push switch, so as to prevent water vapor from contacting the push switch and causing damage or short circuit to the push switch. A temperature sensor 230 is provided at the bottom of the inner barrel 20, and the model of the temperature sensor 230 is PT100. After the push switch is pressed, the temperature sensor 230 is connected to the power supply, so as to start working to detect the real-time temperature in the inner barrel 20.

[0033] The myocardial protective liquid cooling device 100 for surgery of the present invention further includes a controller (not shown in the figure), which is electrically connected to the circulating water pump and the temperature sensor on the coil 131. When the temperature sensor 230 detects that the temperature in the inner barrel 20 is higher than 4°C, the temperature sensor 230 transmits the temperature signal to the controller. After receiving the temperature signal from the temperature sensor 230, the controller controls the circulating water pump to work. At this time, the cooling water circulates in the coil 131 to cool the inner cavity of the inner barrel 20. When the temperature sensor 230 detects that the temperature in the inner barrel 20 is lower than 4°C, the controller controls the circulating water pump to stop working. In addition, the target temperature in the inner cavity of the inner barrel 20 can be set by the medical staff according to the needs of the operation. For example, the set target temperature can be 2°C, 2.5°C, 3°C or 3.5, etc., any other temperature within the range of 2°C-4°C.

[0034] The use process of the above-mentioned surgical myocardial protection fluid cooling device 100 is as follows: the inner barrel 20 is inserted into the connecting column 110 through the cover column 210, thereby determining the position of the inner barrel 20 relative to the outer barrel 10, so that the inner barrel 20 is attached to the side wall of the outer barrel 10, and the coil 131 in the temperature control system is inserted into the inlet pipe 310 and the outlet pipe 320, and then the power gain and loss of the electromagnet 430 is adjusted so that the magnetism of the electromagnet 430 and the magnetic pole of the permanent magnet 422 are the same. Under the action of magnetic repulsion, the elastic force of the elastic member 410 can be cooperated with the push cover 112 to be pushed out of the ejection hole 111. Under the push of the push block 112, the inner barrel 20 can be pushed through the cover column 210, so that the inner barrel 20 is initially pushed out through the outer barrel 10, and finally the wrench cavity 220 is taken out of the outer barrel 10 to facilitate the cleaning and replacement of the inner barrel 20.

[0035] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
