Description

Technical Field

[0001] The utility model relates to the medical field, in particular to an anticoagulation venous pot. Background Art

[0002] Anticoagulation refers to the use of anticoagulant drugs to interfere with blood, interfere with coagulation factors, and prevent blood clotting. It is mainly used for the prevention and treatment of thromboembolic diseases.

[0003] Most patients will use anticoagulants during blood drawing and hemodialysis to prevent the blood from clotting before it is drawn. The venous bottle is a commonly used medical consumable in the blood transfusion process. According to clinical statistics, due to the special location and structure of the venous bottle, the venous bottle is the place where blood clotting is most likely to occur, and thrombosis is most likely to occur during use. Utility Model Content

[0004] The problem to be solved by the utility model is to provide an anticoagulation venous bottle to help reduce blood coagulation in view of the above-mentioned deficiencies in the prior art.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an anticoagulant intravenous pot, comprising an intravenous pot body, wherein the upper and lower ends of the intravenous pot body are respectively provided with a liquid inlet and a liquid outlet, the upper end of the intravenous pot body is provided with a catheter for injecting an anticoagulant, and the end of the catheter is installed with a blocking cap, the intravenous pot body has an inner cavity, the bottom of the inner cavity is provided with an arched filter screen, the inner wall of the inner cavity is provided with a spiral groove, the upper end of the spiral groove is connected to the catheter, a plurality of guide wires are laid in the inner cavity, and the upper ends of the guide wires are connected to the spiral groove.

[0006] Furthermore, the inner wall of the cross section of the spiral groove is a major arc.

[0007] Furthermore, a plurality of the guide wires are connected to each other at intersections.

[0008] Furthermore, the arcuate filter is connected to the bottom one or more guide wires and enables the elastic guide wires to generate elastic force.

[0009] Compared with the prior art, the utility model has the following beneficial effects: the utility model performs blood transfusion by connecting the liquid inlet and liquid outlet ends arranged at the upper and lower ends of the venous pot body to an infusion tube respectively. The blood enters the inner cavity from the liquid inlet and is filtered by the arch filter, and then flows out from the liquid outlet. An anticoagulant is injected into the catheter, and then the anticoagulant flows down along the spiral groove to cover a large area of ​​the inner wall, thereby increasing the contact surface between the blood and the anticoagulant. At the same time, part of the anticoagulant is drained along the guide wire, so that the anticoagulant is diffused along the middle of the inner cavity. The large-area diffusion of the anticoagulant makes the anticoagulant effect more obvious.

[0010] Other advantages, objectives and features of the present invention will be embodied in part through the following description, and in part will be understood by those skilled in the art through research and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 The figure is a schematic diagram of the structure of an anticoagulant intravenous kettle.

[0013] In order to make the technical means, creative features, objectives and functions of the present invention clearer and easier to understand, the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods:

[0014] The utility model proposes an anticoagulant intravenous pot, comprising an intravenous pot body 1, wherein the upper and lower ends of the intravenous pot body 1 are respectively provided with a liquid inlet 2 and a liquid outlet 3, wherein the upper and lower ends of the liquid inlet 2 and the liquid outlet 3 are respectively connected to the intravenous pot body 1, and a catheter 4 for injecting an anticoagulant is arranged at the upper end of the intravenous pot body 1, wherein the connection position between the catheter 4 and the intravenous pot body 1 is located at the upper end of the intravenous pot body 1, and a blocking cap 5 is installed at the end of the catheter 4, wherein the lower connecting end of the catheter 4 is fixedly connected to the intravenous pot body 1 and connected to the inner cavity of the intravenous pot body 1, and the upper end of the catheter 4 is clamped with the blocking cap 5 to block the upper end of the catheter 4, and when in use, the blocking cap 5 is removed to inject the anticoagulant into the inner cavity through the catheter 4, wherein the bottom of the inner cavity is provided with an arched filter screen 6, and the inner wall of the inner cavity is provided with a spiral filter screen 6. Groove 7, the upper end of the spiral groove 7 is connected to the catheter 4, and a plurality of guide wires 8 are laid in the inner cavity. The outer diameter of the guide wire 8 is less than 1 mm. The setting of the guide wire 8 allows the blood passing through to be cut, which helps stirring and reduces the risk of blood coagulation. The upper end of the guide wire 8 is connected to the spiral groove 7; the inner wall of the cross section of the spiral groove 7 is a major arc, and the cross-sectional opening of the spiral groove 7 exceeds the inner direction of the inner cavity; a plurality of the guide wires 8 are connected to each other at the intersection; the arch filter 6 is connected to the bottom one or more of the guide wires 8 and enables the elastic guide wire 8 to generate elastic force. When blood coagulation is found to still begin, the arch filter 6 is disconnected from the guide wire 8 connected thereto by pinching the venous pot body 1. Under the elastic action of the guide wire 8, the multiple connected guide wires 8 oscillate to reduce blood coagulation.

[0015] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
