[0019] The present invention solves the defects existing in the background technology and has the following beneficial effects:

[0020] (1) The present invention provides a drug delivery device and a drug delivery method for anticoagulant drugs after gynecological pelvic surgery. Through the coordinated use of an injection belt and a massage belt, the dual preventive functions of precise injection and intermittent inflation and pressurization are achieved. The injection belt uses microneedle technology and a micro-injection pump to automatically inject anticoagulant drugs into patients according to preset intervals and doses, ensuring accurate drug delivery and effective use. At the same time, the massage belt performs periodic pressure massage on the lower abdomen through the massage component and the top pressure component thereon, promoting blood circulation, reducing blood retention, and further reducing the risk of thrombosis. These two preventive functions produce significant synergistic effects when used in combination, which not only improves the anticoagulant treatment efficiency of patients after gynecological pelvic surgery, but also effectively enhances the safety of treatment. Through the dual effects of drug injection and physical pressurization, the device can more effectively inhibit the formation of thrombi, providing patients with comprehensive and reliable anticoagulant treatment guarantees.

[0021] (2) The present invention provides a drug delivery device and a drug delivery method for anticoagulant drugs after gynecological pelvic surgery. Through a built-in micro-injection pump and a precisely controlled injection unit, the anticoagulant drugs can be automatically injected into the patient according to a preset dose and time interval, ensuring that the drug reaches an optimal blood concentration in the body, thereby effectively inhibiting the formation of blood clots. The spacing between each injection channel is greater than or equal to 2 cm, ensuring that each injection can avoid sensitive areas and repeated injection points. At the same time, the high resilience material of the injection unit allows it to fit the skin during injection, reducing pain and the occurrence of congestion.

[0022] (3) The present invention provides a drug delivery device and a drug delivery method for anticoagulant drugs after gynecological pelvic surgery. By setting a massage component on the massage belt and intermittently inflating and pressurizing, the lower limb blood vessels can be squeezed periodically, thereby accelerating blood flow and reducing the retention time of blood in the veins, thereby reducing the hypercoagulable state of blood and reducing the risk of thrombosis. Intermittent inflation and pressurization can also promote the improvement of lower limb microcirculation, increase the elasticity of blood vessel walls, and further reduce the risk of complications such as DVT. This is particularly important for patients after gynecological pelvic surgery, because the surgery itself may cause hypercoagulable state of blood and microcirculatory disorders.

[0031] As shown in the figure, a drug delivery device and a drug delivery method for anticoagulant drugs after gynecological pelvic surgery include: an injection belt 1 and a massage belt 2 arranged on the outside of the injection belt 1, and the width of the injection belt 1 is smaller than that of the massage belt 2; in the present invention, Velcro is provided at both ends of the massage belt 2 and the injection belt 1, and an insertion hole is opened at the Velcro position near the end point of the massage belt 2, and the injection belt 1 is inserted through the insertion hole at the massage belt 2, and the injection belt 1 is located on the inner side of the massage belt 2.

[0032] It should be noted that the injection belt 1 and the massage belt 2 are stacked, and both ends of the injection belt 1 and the massage belt are fixedly connected with Velcro. The width of the injection belt 1 is smaller than that of the massage belt 2. Before wearing, the injection belt 1 is placed on the side of the massage belt 2 with the airbag, and the two ends of the injection belt 1 are passed through the jacks of the massage belt 2, so that the two ends of the injection belt 1 are located at the bottom of the two ends of the massage belt 2. During the wearing process, the massage belt 2 and the injection belt 1 are fixed to the waist by Velcro, and the two waists are The end points of the belts are both located at the back, and because before being worn, the two ends of the injection belt 1 are located at the bottom of the two ends of the massage belt 2, and the massage belt 2 is worn with one side having an air bag in contact with the skin, the injection belt 1 and the massage belt 2 are worn crosswise around the waist during the wearing process, and are finally fixed by Velcro, at which time the two ends of the injection belt 1 are located on the outside, and the two ends of the massage belt 2 are located on the inside, and the middle part of the injection belt 1 is located on the inside, and the massage belt 2 is located on the outside, so that it is more convenient to inject the drug while fixing it.

[0033] The injection belt 1 comprises: an injection belt 1 body, a plurality of injection units arranged on the injection belt 1 body, and a control unit connected to the injection units; one end of the injection unit is concavely arranged, a plurality of microneedles 11 are arranged at the concave part of the injection unit, and the control unit is used to control the injection unit to perform injection;

[0034] In the present invention, the injection unit includes a plurality of injection channels, each of which runs through the injection belt 1 body, and the injection channels are used to deliver injection drugs, and the spacing between each injection channel is greater than or equal to 2 cm; the injection unit includes a plurality of liquid inlet ends and a plurality of liquid outlet ends, the liquid inlet ends are arranged at the two ends of the injection channels on the outside, and a one-way valve is arranged in each of the liquid inlet ends, and the liquid outlet ends are arranged in a concave shape, and a plurality of microneedles 11 are arranged in the concave part of the liquid outlet ends; the liquid inlet end and the liquid outlet end are respectively arranged on the two side surfaces of the injection belt 1 body, and the liquid outlet end is located on the side close to the skin, and the liquid outlet ends are located at different positions, and the distance from the navel is 6-10 cm; the injection unit also includes a plurality of micro injection pumps, which are arranged in the injection channel, and the micro injection pumps can drive the drug solution to flow in and out of the injection channel; the control unit includes a control module, a position sensor, a pressure sensor and a temperature sensor, and the control module controls the position sensor, the pressure sensor and the temperature sensor for detection, and controls the injection belt 1 to inject and the massage belt 2 to press.

[0035] It should be noted that the injection channel is used to fill and inject the medicine. Before wearing, the medicine is filled into the injection channel through the one-way valve at the liquid inlet end. The one-way valve here controls the medicine to only enter the injection channel but not flow out of the injection channel. A liquid outlet is arranged in the middle part of the injection channel. The distance between the liquid outlet and the navel is 6-10cm, and the distance between each injection channel is greater than or equal to 2cm. The liquid outlet is arranged in an arc-shaped groove, and a number of microneedles 11 are arranged in the depression of the groove. The high resilience material is used here. When the device is injecting, the airbag squeezes the depression so that the depression fits the skin. At this time, the micro-injection pump controls the medicine to flow through the injection channel to the microneedle 11, and is injected into the body through the microneedle 11. Before, after and during the injection, the position sensor can accurately sense the position of the belt on the body and the distance of each injection point relative to the navel. They ensure that each injection avoids the sensitive area of ​​5 cm around the navel. The pressure sensor is used to detect the contact pressure between the belt and the skin to ensure stability and comfort during injection. The temperature sensor monitors the skin temperature to evaluate the blood circulation at the injection site, so as to select the area with better blood circulation for injection and reduce the risk of pain and congestion. In this way, the injection belt 1 automatically injects anticoagulants into the patient at preset intervals, avoiding the errors and inconveniences that may be caused by manual injection. This not only improves the utilization rate of the drug, but also ensures that the patient can receive anticoagulant treatment continuously and stably throughout the recovery period. The control unit and injection unit can strictly control the drug dosage for each injection to ensure that the drug reaches the optimal blood concentration in the body, thereby effectively inhibiting the formation of blood clots. This precision avoids the risk of bleeding caused by excessive injection and the poor anticoagulant effect caused by insufficient dosage.

[0036] The massage belt 2 includes: a massage belt 2 body, a massage component 21 arranged on the massage belt 2 body, a top pressure component arranged at the gap of the massage component 21, and an air pump; the air pump can inflate and deflate the massage component 21 and the top pressure component 22 respectively, and the massage component 21 can evenly pressurize the lower abdomen to promote venous return in the lower limbs.

[0037] In a preferred embodiment of the present invention, the massage component 21 and the top pressure component 22 have the same structure and are both composed of a plurality of air bags. The air bags of the massage component 21 are evenly arranged on the side of the massage belt 2 body that fits the skin, and the air bags of the top pressure component 22 are located in the gaps between the air bags of the massage component 21 and are on the same axis as the liquid outlet.

[0038] It should be noted that the massage component 21 and the top pressure component 22 are two different air bags, and the two different air bags are controlled by an air pump. The injection channel is arranged in the gap between the air bags of the massage component 21 on the same horizontal plane. At the same time, the top pressure component 22 is also arranged in the gap between the air bags of the massage component 21, and the air bag of each top pressure component 22 and the recessed part of the liquid outlet are also located on the same axis. When injecting, the intermittent inflation and pressurization of the massage component 21 can periodically squeeze the blood vessels of the lower limbs, thereby accelerating blood flow and reducing the retention time of blood in the veins, which helps to reduce the hypercoagulable state of blood and reduce the formation of thrombus. In addition, the pressurization therapy can also promote the improvement of microcirculation in the lower limbs, increase the elasticity of the blood vessel wall, and further reduce the risk of DVT. The top pressure component 22 can accurately control the position of the microneedle 11 by accurately controlling the amount of inflation inside the top pressure component 22.

[0039] A method for administering anticoagulant drugs after gynecological pelvic surgery, comprising the following steps:

[0040] The massage component 21 massages the waist to promote blood circulation, and the control unit performs real-time detection; the pressing component 22 expands to press the depression of the injection unit so that the depression fits the skin, and the injection unit controls the internal liquid to flow out from the microneedle 11 for injection; the pressing component 22 contracts, and the injection unit restores its deformation, and the airbag of the massage component 21 surrounding the lower abdomen expands and contracts evenly to massage the lower abdomen and promote venous return in the lower limbs.

[0041] The control unit detects the lower abdomen in real time through the position sensor, the pressure sensor and the temperature sensor, and controls the massage component 21 and the pressing component 22 to perform massage and medication through the control module.

[0042] In this way, by combining the injection belt 1 and the massage belt 2, the two preventive functions of precise injection and intermittent pneumatic pressurization can produce a synergistic effect when used together, further improving the efficiency and safety of anticoagulation treatment for patients after gynecological pelvic surgery. Through the dual effects of drug injection and physical pressurization, the device can more effectively inhibit the formation of blood clots and provide patients with comprehensive anticoagulation treatment guarantees. The combined use of precise injection and intermittent pneumatic pressurization not only reduces the incidence of DVT, but also reduces the pain and discomfort of patients, improves the quality and satisfaction of patients' rehabilitation, and reduces the occurrence of complications such as DVT. The device helps to reduce patients' medical costs and hospitalization time, thereby reducing the economic burden on patients and their families.

[0043] The above is based on the ideal embodiment of the present invention. Through the above description, relevant personnel can make various changes and modifications without departing from the technical concept of the present invention.
