It should be noted that the disclosed literature is only a simple heating for peritoneal dialysis, and is not suitable for various patients in clinical practice, such as patients with other underlying diseases, such as heart disease. Such patients may have various pains and various complications during blood transfusion. Therefore, in order to ensure the comfort of kidney perfusion dialysis, it is necessary to improve the temperature control scheme.

In addition, it should be noted that only the parts related to the application are shown in the drawings for ease of description.
[0019] The drawings in the embodiments of the application: different kinds of section lines in the drawings are not marked according to the national standard, nor do they require the material of the element, but they distinguish the section view of the element in the drawing.
[0020] Please refer to Figure 1 - Figure 15 A constant-temperature renal perfusion fluid delivery device: Embodiment 1 Please refer to the drawings in the description Figure 1 - Figure 4 as shown: It comprises a constant-temperature mechanism 1, a perfusion mechanism 2 and a pressurized delivery mechanism 3. The constant-temperature mechanism 1 is a constant-temperature heating mechanism that maintains a preset range. The perfusion mechanism 2 flows into the stoma of the patient. The constant-temperature mechanism 1 comprises a modular assembly seat 11, a disposable blood filter box 12, a plurality of warm core rods 13 and a branch pipe 14 for blood supply. The disposable blood filter box 12 is installed on the surface side of the modular assembly seat 11, and the plurality of warm core rods 13 are sequentially clamped in the arc groove 121 of the disposable blood filter box 12. The warm core rod 13 is connected with the intelligent temperature control box 131 through the heat-conducting wire, and the bottom of the intelligent temperature control box 131 is fixedly placed on the other side of the modular assembly seat 11, and the other end of the branch pipe 14 is connected with the pipe of the disposable blood filter box 12. The disposable blood filter box 12 and the branch pipe 14 can be replaced. The intelligent temperature control box 131 is electrically controlled by the intelligent control unit and the body temperature detection mechanism 4. The body temperature detection mechanism 4 is composed of an intelligent temperature sensor 41, a receiving antenna 42, a flexible winding cable 43, and a wireless body temperature detection rod 44 for collecting the body temperature of the patient. The back of the wireless body temperature detection rod 44 is provided with a detachable battery. The wireless body temperature detection rod 44 is bound to the patient's shoulder armpit through the elastic pressure band 45; The intelligent temperature sensor 41 is installed on the side wall of the modular assembly seat 11; The side of the modular assembly seat 11 is also provided with a linear sliding rail 111. The intelligent temperature sensor 41 is assembled through the linear sliding rail 111. The flexible winding cable 43 is electrically connected to the receiving end of the intelligent temperature sensor 41. The receiving antenna 42 is installed at the end of the flexible winding cable 43; The flexible winding cable 43 is wound on the surface of the stoma tube; The constant temperature mechanism 1 is electrically controlled by the intelligent control console 5; The intelligent temperature sensor 41, the wireless body temperature detection rod 44, the intelligent temperature control box 131, and the warm core rod 13 are electrically connected to the intelligent control console 5.
[0021] Temperature control is controlled by the intelligent control console 5. The main dialysis is responsible for the main dialysis of the main dialysis.
[0022] Step one: First of all, how to realize the temperature control function of the blood intelligentization of the patient's stoma implantation; At this moment, when the blood has been filtered by the host, the automatic drainage of the blood is realized through the bottom of the filter membrane sleeve 196, and a part of it is collected into the disposable blood filter box 12, and then the intelligent temperature control box 131 is controlled by the intelligent control console 5 to make the warm core rod 13 auxiliary heating operation; (1) Premise: First, get the patient's armpit temperature (this temperature is generally kept within the appropriate range of human body temperature. If the temperature is too high, the heating temperature should be appropriately reduced. If the temperature is too low, the temperature should be appropriately increased to maintain balance) At this time, the medical staff needs to clamp the wireless body temperature detection rod 44 with wireless connection in the patient's hydraulic pressure. In order to avoid falling, the elastic pressure band 45 can be used to bind the patient's wrist, directly clamp it to avoid falling, and there is no need to worry about data acquisition problem. Through short distance wireless, real-time information is received. The communication protocol is LoRa. Moreover, the wireless body temperature detection rod 44 itself is powered by a detachable battery, which is a No. 7 carbon zinc battery. The receiving end is connected with the receiving antenna 42. The latter half of the receiving antenna 42 is connected with the flexible winding cable 43, which can be matched and wound on the warm stoma connecting tube 34. The surface of the soft material is wrapped with a layer of nylon textile thread. The inside is soft like a wire, which can be easily bent like a binding band, and directly layer by layer wound on the stoma connecting tube 34 to realize auxiliary heating; Moreover, the flexible coiled cable 43 here also has an auxiliary heating function, and the information received from the wireless body temperature detection stick 44 is achieved through the receiving antenna 42. The specific value of the heated blood temperature is controlled by a wireless thermometer 44 that acquires the axillary temperature of a patient. (2) Heating the blood: Here, the anticoagulant is administered to ensure that the blood does not coagulate prematurely. Therefore, the delivered blood will flow into the branch tube 14 in a timely manner. The temperature of the heating core 13 is coordinated by the intelligent temperature control box 131. The heat collected inside the disposable blood filter box 12 can be distributed on the outer wall surface of the disposable blood filter box 12. The blood is diverted and uniformly placed into the disposable blood filter box 12 through the branch tube 14. One end of the heating core 13 provides direct auxiliary heating to ensure that the blood inside is heated to a state that is more suitable and acceptable to the patient's body temperature. Moreover, the temperature of the blood being heated is freely controllable, and the blood pressure after heating will be exported from the disposable blood filter box 12 to the clean blood delivery cannula 23. Because the blood on the other side is branched, there is a concern that a single blood delivery may cause blockage and low efficiency. Therefore, a dual-channel solution is adopted. The clean blood pressure on the other side is also collected and converged from inside the blood collection tube 222 into the clean blood delivery sleeve 23. To avoid any loss of blood pressure temperature from auxiliary heating, since the blood collected above is not heated, it is wound around the pressure-boosting sleeve 31 by a flexible winding cable 43. Why is it placed at this position? Because this is exactly where the blood is finally injected into the patient's stoma connection tube, so less heat is consumed and the clean blood that comes in does not coagulate prematurely. Intelligent temperature control: According to the information detected by the wireless body temperature detection stick 44 connected by the corresponding signal, the two work together to ensure that the temperature of the heated blood has a precise balance with the patient's body temperature. When the patient's temperature is slightly low, it means that there is an obvious physical problem with the blood transfusion, so the blood is heated slightly higher. If the patient has a fast heart rate or some skin redness and swelling, indicating obvious temperature problems, then the subtle changes can be detected in time through body temperature, and the temperature of the heated blood can be slightly lowered. At this moment, the blood pressure flow rate is determined by an external heart rate monitor, and the rate at which blood is injected can be based on the heart rate changes reported every second. Example 2: Please refer to the instruction manual appendix. Figure 5 - Figure 9 As shown: The booster conveying mechanism 3 consists of: a booster sleeve 31, a booster pump 32, and a frequency converter 33; The booster pump 32 is sealed and connected to the side wall of the blood collection tube 222. The side wall of the booster pump 32 is connected to a booster sleeve 31 for infusion. The side wall of the booster pump 32 is provided with a frequency converter 33. The conductive end of the frequency converter 33 is electrically connected to the positive and negative poles of the booster pump 32.
[0023] After the blood is purified through the dialysis machine, the efficiency of the blood dialysis is automatically and micro-controlled according to the patient's heart rate and the strength of the blood pump, so as to avoid various discomfort reactions of the patient due to physical reasons. The pressurizing sleeve 31 is connected to a stoma connection tube 34, which is connected to the patient's arteriovenous fistula. The purpose is to allow the delivered blood to be connected to the stoma site, purified by blood extraction, and then transfused to form a cycle.
[0024] The modular assembly base 11 has symmetrically installed support side plates 15 on both sides of its surface. The dialysis host 16 is installed on the top of the two support side plates 15. The perfusion mechanism 2 includes: a connecting seat 21, several U-shaped blocks 22, a blood collection tube 222, and a clean blood delivery sleeve 23. Connector seats 21 are sequentially arranged on one side of the outer wall of the dialysis unit 16; Several U-shaped locking blocks 22 are engaged and connected to the connecting seat 21. The top of the blood collection tube 222 is sealed and connected to the flow rate detector 221. The clean blood delivery sleeve 23 is connected to the bottom of the blood collection tube 222. The connector 21 and U-shaped clamp 22 are used to assemble with the clean blood delivery cannula 23. Since it is a disposable medical waste, the connector 21 and U-shaped clamp 22 are used to clamp the blood collection tube 222 and the clean blood delivery cannula 23. After the patient finishes dialysis, it is directly discarded and replaced with a new one. In addition, the purpose of the blood collection tube 222 is to collect the purified blood and then return it to the patient's body through the vein, just like a blood transfusion bag.
[0025] Step Two: Blood is supplied to the patient's body; At this point, the purified blood is drawn into the pressure-boosting sleeve 31 via the booster pump 32. The frequency converter 33 analyzes and detects various indicators of the human body from multiple perspectives, and comprehensively controls the blood-drawing intensity of the booster pump 32. The evaluation criteria are as follows: 1. Blood pressure: Some people have high blood pressure and a strong heart pump, which can cause dizziness if the blood is pumped too fast. So, blood pressure should be lowered slightly. Others have a slow heart rate and low blood pressure, which can cause shortness of breath and dizziness if the blood is pumped too slowly. Therefore, based on the intensity of the heart rate and the actual data of blood pressure, plus the frequency of breathing, these can be measured using an external blood pressure and heart rate measuring device. Alternatively, critically ill patients can be monitored with a ventilator. The purpose is to detect any adverse reactions that may occur during renal perfusion. 2. Heartbeat If the heart rate is too fast, it needs to be slowed down; if the heart rate is too slow, the blood supply rate can be controlled by the frequency converter 33 to control the booster pump 32 to maintain a relative balance. Example 3: Please refer to the instruction manual appendix. Figure 10 - Figure 15 As shown: Several hemodialysis agent storage units 17 are arranged sequentially on the top surface of the dialysis unit 16; Several hemodialysis agent storage units 17 are connected to several hemodialyzers 18 at their bottoms. The interior of the hemodialyzers 18 is connected to several hemodialysis agent storage units 17 for dialysate exchange. A plurality of raw blood inlet tubes 19 are provided at the bottom of the hemodialysis agent storage 17, and one end of the plurality of raw blood inlet tubes 19 is connected to the blood pump inlet in the dialysis host 16. A semipermeable membrane 191 is placed on the surface of the hemodialyzer 18. The hemodialysis agent storage 17 is connected to the dialysate concentration supply unit. The blood pump outlet is connected to both the semipermeable membrane 191 and the dialysate concentration supply unit.
[0026] The removal of impurities and harmful substances from the patient's blood is achieved by continuously delivering the hemodialysis agent using the hemodialysis agent storage 17. The hemodialysis agent is delivered through the semipermeable membrane 191 and the blood pump, and continuously circulates on the other side of the semipermeable membrane 191, attracting impurities into the dialysate like a magnetic field. The blood pump continuously delivers the turbid blood, thus achieving blood purification.
[0027] The hemodialyzer 18 contains dialysate, which exchanges blood waste with the blood through a semipermeable membrane 191. The hemodialyzer 18 is connected to a clean blood delivery tube 192 at the outlet. A hazardous substance detector 193 is installed at the bottom of the clean blood delivery tube 192. A blood detector 194 is installed on the side of the hazardous substance detector 193. The side of the blood detector 194 is connected to one branch of the clean blood delivery tube 192 through multiple disposable connectors 195.
[0028] The blood detector 194 and the harmful substance detector 193 are used to analyze the impurities in the blood. One is before the blood is tested and the other is after the blood is purified. The two have comparison indicators to coordinate the blood purification intensity. The disposable connector 195 and the clean blood delivery tube 192 are used to achieve tube connection.
[0029] The end of the clean blood delivery tube 192 is connected to a filter membrane sleeve 196. One end of the filter membrane sleeve 196 is sealed and connected to the side wall of the blood collection tube 222. The side wall of the clean blood delivery tube 23 is provided with a pressure boosting delivery mechanism 3.
[0030] The filter membrane sleeve 196 is used as the final filter for blood and is finally placed on the surface of the blood collection tube 222 to achieve purification.
[0031] The side wall of the hemodialysis machine 18 is also equipped with an automatic anticoagulant injector 181, which is sealed and connected to the filter membrane sleeve 196.
[0032] The purpose of using the automatic anticoagulant injector 181 is to address the issue that some patients have excessively strong clotting abilities, causing freshly drawn blood to coagulate rapidly upon contact with cold. To improve this situation, the automatic anticoagulant injector 181 can be set to inject a certain amount of anticoagulant medication, thereby resolving the problem and maintaining the normal operation of dialysis.
[0033] The top of the dialysis host 16 is supported by an intelligent dialysis terminal 161. The dialysis host 16, hemodialyzer 18, hemodialysis agent storage 17, blood pump, blood detector 194, dialysate concentration supply unit, harmful substance detector 193 and anticoagulant automatic injector 181 are all electrically connected to the intelligent dialysis terminal 161.
[0034] Intelligent control is more harmonious than manual operation; the operation is programmed and highly efficient.
[0035] Step 4: The previous step, blood filtration; At this time, blood pressure filtration is still achieved through the stoma in the arm. The contaminated blood will be drawn from the other side of the patient's stoma and then placed into the main body of the dialysis machine for filtration. The specific filtration process involves having blood from the patient's stoma. The blood containing toxins is directly inserted from the original blood inlet tube 19 into the dialysis unit 16. Pressurized by a blood pump, it is then inserted into the hemodialyzer 18. The blood undergoes exchange with the hemodialysis agent flowing from one side of the semi-permeable membrane 191, resulting in the removal of some contaminants from the blood. If the patient's anticoagulation is found to be poor, the intelligent dialysis terminal 161 can automatically control and analyze the coagulation characteristics, toxins in the blood, and impurities that cannot be filtered by the kidneys. These are detected by the blood detector 194 and the harmful substance detector 193. Based on the established logic, the automatic anticoagulant injector 181 is automatically controlled to administer the coagulation needle. The rotation speed of the semi-permeable membrane 191 inside the hemodialyzer 18 can also be controlled; increasing the rotation speed improves the efficiency of removing impurities from the blood. After filtering the blood, the blood quality of the dialysis-completed blood and the blood before dialysis are compared and tested by the blood detector 194 and the harmful substance detector 193. Finally, the blood is diverted from the clean blood delivery tube 192 and the disposable connector 195, with one side collecting in the pressurizing sleeve 31 and the other side being delivered to the filter membrane sleeve 196. Finally, the blood can be heated and then returned to the blood vessel through the stoma connection tube 34. This stoma structure is responsible for both blood transfusion and blood extraction. In addition, the heart rate and flow rate detector 221 ensures that the blood pressure delivery speed is more stable. Finally, according to the blood pressure index detection, the pump body, i.e., the pressure delivery mechanism 3, is controlled to remove pressure. The intelligent control console 5 functions as a small PLC controller for automated control of body temperature analysis. It controls the comprehensive evaluation and analysis of the intelligent temperature sensor 41, the wireless body temperature detection rod 44, the intelligent temperature control box 131, and the warming core rod 13 to obtain a temperature suitable for the patient's body.
