Description
Technical Field
The utility model relates to a inferior low temperature treatment technical field especially relates to an induced simulation platform of intravascular low temperature.
Background
The sub-hypothermia treatment is to reduce the core temperature of a patient to 32-35 ℃, namely, to form a sub-hypothermia region so as to prevent or reduce nerve damage caused by various reasons. Sub-hypothermia therapy has been widely accepted in some fields as an effective neuroprotective measure and can be used for hypothermic neuroprotection of ischemic stroke. The main nerve protection mechanism is that the nerve protection mechanism can influence the metabolism rate and the apoptosis mechanism of a human body, and the mechanism comprises the generation of inhibiting free radicals and inflammatory factors, reducing the calcium ion inflow phenomenon caused by ischemia, protecting the blood brain barrier and the like.
The sub-hypothermia treatment can be divided into three stages, namely inducing hypothermia, maintaining hypothermia and rewarming, target temperature control is taken as a key parameter of the sub-hypothermia treatment, and the low temperature induction rate, the low temperature range, the low temperature implementation mode, the maintaining time, the rewarming rate and the like all influence the treatment effect of hypothermia on neuroprotection. Therefore, during the process of sub-hypothermia treatment, the selection of the mode of low temperature induction and maintenance is of great importance.
Low temperature induction is generally divided into body surface hypothermia and intravascular hypothermia, wherein intravascular hypothermia is widely accepted due to its precise temperature control capability. However, the temperature reduction effect of the current intravascular low temperature induction technology is related to the blood flow state of the target site in addition to the low temperature induction parameters. Therefore, the cooling effect needs to be known in a simulation experiment; especially, under the ischemia state of carotid artery, the influence of the flow change of blood flow on the cooling condition provides theoretical support for formulating the local target low-temperature neuroprotection strategy of ischemic stroke.

The carotid artery model tube 4 is provided with a second temperature sensor 13, and the second temperature sensor 13 is positioned between the second catheter 10 and the elastic membrane 12.
In this embodiment, the liquid flows in the circulatory system composed of the heatable reservoir 1, the first pressure pump 2, the aortic arch mode tube 3 and the carotid mode tube 4, thereby simulating the circulatory flow of blood in the human body. More specifically, the heatable fluid reservoir 1 may heat the fluid to simulate a temperature environment within a human body (e.g., the fluid in the heatable fluid reservoir 1 may be maintained at 37 degrees Celsius); the first pressure pump 2 is used for providing power for the circulating flow of the liquid; the aortic arch model tube 3 simulates the aortic arch of a human body; the carotid artery model tube 4 simulates the carotid artery of a human body.

In addition, it should be noted that heatable liquid storage pot 1 and low temperature liquid storage pot 5 are common devices, the utility model discloses no longer describe its structure and principle. For example, the heatable liquid storage tank 1 comprises a liquid storage tank, an electric heating device and a temperature sensor, wherein the electric heating device can heat the liquid in the liquid storage tank so as to maintain the liquid in the liquid storage tank at 37 ℃; the temperature sensor is used for monitoring the liquid in the liquid storage tank, and the electric heating device is turned on or turned off in time, so that the liquid in the liquid storage tank is prevented from being too high or too low in temperature. For another example, the low-temperature liquid storage tank 5 includes a liquid storage tank and a heat insulation layer, wherein low-temperature liquid (for example, low-temperature liquid with a temperature range of 32-35 ℃) is stored in the liquid storage tank, and the heat insulation layer can maintain the liquid in the liquid storage tank at a low temperature.

The elastic membrane 12 may be a membrane made of an elastic material commonly used in the art, such as a rubber membrane. And the elastic membrane 12 is preferably glued to the inner wall of the carotid model tube 4.

When the bolt 11 is screwed toward the carotid artery model tube 4, the tip of the bolt 11 applies a pushing force to the elastic membrane 12 to arch the elastic membrane 12. And the part of the elastic membrane 12 from the side close to the head end of the carotid artery model tube 4 to the tail end of the bolt 11 is gradually arched, and the part of the elastic membrane 12 from the side far away from the head end of the carotid artery model tube 4 to the tail end of the bolt 11 is relatively sharply arched, or in other words, the distance between the side close to the head end of the carotid artery model tube 4 and the tail end of the bolt 11 is larger than the distance between the side far away from the head end of the carotid artery model tube 4 and the tail end of the bolt 11.

The elastic membrane 12 is cylindrical, and two axial ends of the elastic membrane 12 are hermetically connected with the inner wall of the carotid artery model tube 4.

In this embodiment, two or more screw holes are spaced around the carotid artery model tube 4 and when all the bolts 11 are screwed into the carotid artery model tube 4, the elastic membrane 12 will arch in a ring shape, simulating a thrombus that is distributed around the inner wall of the vessel in a ring shape. And the moving length of different bolts 11 to the carotid artery model tube 4 can be different, so that the arched part of the elastic membrane 12 is in a state of fluctuation, thereby being more close to the actual shape of thrombus in the human blood vessel and obtaining more accurate research data.
In the present invention, a plurality of the fingers means two or more.
In some embodiments, the number of screw holes is multiple, all of which are arranged at intervals along the extension direction of the carotid artery model tube 4, and each of which is provided with a bolt 11. Some thrombi in the human carotid artery may have a long longitudinal length (i.e., the direction of extension of the blood vessel). In the embodiment, two or more screw holes are arranged at intervals along the extending direction of the carotid artery model tube 4, and by screwing all the bolts 11 and making the bolts 11 extend into the carotid artery model tube 4 with different lengths, various shapes of thrombus with longer longitudinal length can be simulated, thereby being closer to the actual shape of thrombus in human blood vessels and obtaining more accurate research data.

The pressure sensor 20 may monitor the pressure of the liquid before it enters the head end of the aortic arch model tube 3.
In some embodiments, a fourth temperature sensor 16 is provided between the second pressure pump 6 and the second conduit 10.
In this embodiment, the fourth temperature sensor 16 may measure the temperature of the fluid from the cryogenic fluid reservoir 5, thereby simulating the measurement of the temperature of the cryogenic perfusion fluid prior to entering the blood circuit.
In some embodiments, a fifth temperature sensor 17 is provided between the end of the aortic arch model tube 3 and the liquid inlet of the heatable reservoir 1.
In this embodiment, the fifth sensor may measure the temperature of the fluid exiting the distal end of the aortic arch model tube 3, thereby simulating the measurement of the temperature of the blood in the non-sub-hypothermic treatment region.
In some embodiments, the second pressure pump 6 is in communication with the second conduit 10 via a connecting tube, which is removably connected to the second conduit 10.
In this embodiment, the second guide duct 10 may be directly inserted into the end of the connection pipe. The second conduit 10 may also be connected to the connecting tube by a connector 18; specifically, the joint 18 has a tubular shape, one end of the joint 18 is connected to the connection pipe, and the other end of the joint 18 is connected to the second pipe 10.
