Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a thrombus aspiration auxiliary meter. Background Art

[0002] Intravascular thrombosis can be treated with anticoagulant therapy, using drugs such as unfractionated heparin, low molecular weight heparin, dapaparinux sodium, warfarin, or newer anticoagulants. The choice depends on the patient's specific circumstances. Thrombolytic therapy, such as urokinase or recombinant tissue plasminogen activator, is also an option for high-risk patients with pulmonary thrombosis.

[0003] Clinically, patients with high-risk pulmonary artery thrombosis in the main trunk or major branches of the pulmonary artery can undergo pulmonary artery catheter fragmentation and thrombus aspiration, which is an interventional procedure. Pulmonary artery thrombectomy is a treatment measure taken for high-risk patients. Since there is currently no quantification of the extracted thrombus or operation, when doctors record the patient's medical history after surgery, they usually use words such as "a lump" or "a pile" to describe the amount of thrombus extracted to determine (evaluate) the impact of the thrombus on the organ. However, such non-quantitative records cannot provide a good auxiliary role in subsequent medication treatment.

[0004] Based on this, the technical solution of the present application has created a quantitative method for thrombus extraction, which can accurately administer medication by quantifying the thrombus and provide the best treatment plan. Utility Model Content

[0009] Furthermore, the inlet is connected to an inlet threaded joint via a first short tube, and the outlet is connected to an outlet threaded joint via a second short tube.

[0010] Furthermore, the first short pipe and the second short pipe are respectively provided with mechanical control valves.

[0014] Furthermore, the thrombus interception mechanism includes a cylindrical interception net bag, one end of which is open and sealed and fixed to the inlet end of the tube shell, and a hollow support frame is provided on the outer surface of the interception net bag.

[0026] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0027] Example: Figure 1 、 2 As shown in Figures 3 and 4, the thrombus aspiration auxiliary meter of this embodiment includes a tube shell 1 and a thrombus interception mechanism 2. The two ends of the tube shell 1 are respectively provided with an inlet and an outlet connected to the inner cavity thereof. The thrombus interception mechanism 2 is arranged in the tube shell 1 and is located between the inlet and the outlet for intercepting thrombi in the blood.

[0028] When in use, the thrombus aspiration auxiliary meter of this embodiment is connected to the pipeline for extracting thrombi, and the thrombus aspiration auxiliary meter is weighed before the operation. Specifically, the inlet and outlet are respectively connected in series to the pipeline for extracting thrombi. After the thrombus enters the interior of the tube shell 1 through the inlet along with the blood, the thrombus interception mechanism 2 is located between the inlet and the outlet. Therefore, the blood can pass through the thrombus interception mechanism 2, while the thrombus is intercepted by the thrombus interception mechanism 2. After the operation, the entire thrombus aspiration auxiliary meter is weighed, and the difference between the postoperative weighing and the preoperative weighing is calculated. The difference is the mass of the intercepted thrombus. The extracted thrombus is quantified using the above scheme, and the doctor sets the subsequent standardized optimal drug administration plan based on the value. The entire meter structure is simple and reasonable in design. The meter can quantify the extracted thrombus, which helps to set the measurement standard for the same thrombus extraction and facilitates the doctor to quantify the drug administration based on the thrombus quality data.

[0029] It should be added that: in the medical community, the subsequent treatment and medication standards for similar patients can be unified according to the amount of thrombus extracted from such patients, so as to achieve a standardized medication and treatment plan for such conditions in the entire medical field. Therefore, this meter is a relatively cutting-edge and pioneering auxiliary treatment method.

[0030] As a preferred embodiment, Figure 1 As shown, the inlet is connected to an inlet threaded joint 11 through a first short pipe, and the outlet is connected to an outlet threaded joint 12 through a second short pipe.

[0031] In the above embodiment, conventional medical threaded connectors (inlet threaded connector 11 and outlet threaded connector 12) are connected to the inlet and outlet respectively, so as to facilitate quick connection with other pipeline connectors.

[0032] In this embodiment, since the thrombus aspiration auxiliary meter needs to be weighed after surgery, it needs to be removed from the pipeline. Blood is a source of contamination, so the inlet and outlet need to be sealed before weighing. The technical solution of this application adopts at least the following two methods to achieve the above purpose:

[0033] 1) If Figure 3 As shown, the first short pipe and the second short pipe are respectively provided with a mechanical control valve 14.

[0034] In the solution 1), mechanical control valves 14 (using the knob-type mechanical valves of the prior art) are respectively provided on the first short pipe and the second short pipe, which are relatively simple and convenient to operate.

[0035] 2) If Figure 4 As shown, a one-way valve structure is provided in the above-mentioned inlet, and a mechanical knob valve is provided at the outlet.

[0036] Specifically, such as Figure 5 As shown, the one-way valve structure includes a plurality of fan-shaped valves 131 , and the plurality of valves 131 are circumferentially connected to the corresponding inlet and outlet.

[0037] In the above-mentioned solution 2), a one-way valve structure with a valve structure is respectively provided in the inlet. Specifically, when blood enters the inlet, multiple valves 131 are deformed and opened toward the outlet under pressure. The multiple valves 131 in the outlet also have the same mechanism. When the thrombus is extracted, the thrombus aspiration auxiliary meter is removed, and the blood will not flow back from the inlet, and automatic inlet closure can be achieved. At the same time, the mechanical knob valve at the outlet is controlled to close the outlet.

[0038] In this embodiment, the thrombus interception mechanism 2 includes at least the following two structural forms:

[0039] ① Such as Figure 1 As shown, the thrombus interception mechanism 2 includes a fixing ring 21 and an interception net 22 arranged in the fixing ring 21 . The outer edge of the fixing ring 21 is sealed and fixed to the inner wall of the tube shell 1 .

[0040] In the above-mentioned solution ①, the thrombus interception mechanism 2 is set in the part near the outlet of the tube shell 1. The thrombus interception mechanism 2 is a sheet-like component. The fixing ring 21 on the outer edge is connected and fixed to the inner wall of the tube shell 1. The internal interception net 22 plays the role of intercepting thrombus and enables blood to pass smoothly.

[0041] ② If Figure 2As shown, the thrombus interception mechanism 2 includes a cylindrical interception net bag 23 , one end of which is open and sealed and fixed to the inlet end of the tube shell 1 , and a hollow support frame 24 is provided on the outer surface of the interception net bag 23 .

[0042] In the above solution ②, the thrombus interception mechanism 2 is a cylindrical interception net bag 23. After blood and thrombus enter, the blood passes through and the thrombus is intercepted in the interception net bag 23. The supporting frame 24 can ensure that the interception net bag 23 is in an expanded state.

[0043] As a preferred embodiment, the tube shell 1 includes a transparent cylindrical shell 111 and two plugs 112 . The two plugs 112 are respectively sealed and assembled at both ends of the cylindrical shell 111 . The plugs 112 are provided with the inlet or outlet.

[0044] In the above embodiment, the shell and tube 1 has a simple structural design, and the plugs 112 at both ends are easy to connect the inlet and outlet as well as the pipeline, so the design is relatively simple and reasonable.

[0045] In this embodiment, the cylindrical shell 111 is made of medical polyethylene.

[0046] In this embodiment, the tube shell 1 is a round tube member with a beautiful appearance.
