Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of platelet preparation devices, in particular to a multifunctional concentrated platelet preparation sleeve. Background Art
[0002] Platelet concentrates are commonly used component blood transfusion products in surgery. There are generally two types: manual preparation and machine collection. Platelet concentrates are mainly used clinically for patients with thrombocytopenia and obvious blood loss symptoms who need surgery, or as regenerative medicine materials in tissue damage repair. In the preparation process of platelet concentrates, blood is generally centrifuged with the help of centrifuge tubes and centrifuges to obtain concentrated platelets. The current platelet preparation device is cumbersome and easily contaminates the platelets, which cannot meet the needs of use. Utility Model Content
[0003] In order to solve the above technical problems, the technical solution provided by the utility model is: a multifunctional concentrated platelet preparation sleeve, comprising a PRP storage tube and an inner tube arranged in the PRP storage tube, one end of the PRP storage tube is provided with a blood collection connecting tube, and the other end is provided with opening one, the inner tube extends into the PRP storage tube from the opening one, the end of the inner tube located in the PRP storage tube is provided with a funnel connecting piece connected to the inner tube, the funnel connecting piece is adapted to the inner diameter of the PRP storage tube, the end of the inner tube away from the funnel connecting piece is provided with opening two, a piston pull rod extending from opening two is provided in the inner tube, and a sealing cover is provided on the blood collection connecting tube.
[0004] Compared with the prior art, the utility model has the following advantages: the utility model takes place in a closed environment throughout the entire process from blood collection to the preparation of concentrated platelets required for clinical use, thereby avoiding contamination; the utility model can prepare the required product by one centrifugation method, and can accurately measure the platelet concentration when a higher concentration and the required concentration are required in clinical practice. It is not only used in clinical practice, but also suitable for scientific research use. BRIEF DESCRIPTION OF THE DRAWINGS
[0005] Figure 1 The utility model is a structural schematic diagram of a multifunctional platelet concentrate preparation sleeve.
[0006] Figure 2 The utility model is a schematic diagram of the internal structure of a multifunctional platelet concentrate preparation sleeve. DETAILED DESCRIPTION
[0007] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.
[0008] In the description of the embodiments of the present utility model, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate an orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, it is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.
[0009] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components must be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0010] In the description of the embodiments of the present invention, "multiple" means at least 2.
[0011] In the description of the embodiments of the present utility model, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0012] Example:
[0013] Combined with Figure 1-2The present embodiment discloses a multifunctional concentrated platelet preparation sleeve, comprising a PRP storage tube 1 and an inner tube 2 arranged in the PRP storage tube 1, wherein a blood collection connecting tube 3 is arranged at one end of the PRP storage tube 1, and an opening one is arranged at the other end, and the inner tube 2 extends into the PRP storage tube 1 from the opening one, and a funnel connecting piece 4 connected to the inner tube 2 is arranged at one end of the inner tube 2 located in the PRP storage tube 1, and the funnel connecting piece 4 is adapted to the inner diameter of the PRP storage tube 1, and an opening two is arranged at one end of the inner tube 2 away from the funnel connecting piece 4, and a piston pull rod 5 extending from the opening two is arranged in the inner tube 2, and a sealing cover is arranged on the blood collection connecting tube 3; an inner spiral connected to a blood collection device is arranged on the inner wall of the blood collection connecting tube 3.
[0014] In specific implementation, the blood collection connecting tube is a spiral interface, which is convenient for direct use with a blood collection needle and sealing the tube during centrifugation. After blood collection is completed, a sealing cover is inserted into the blood collection connecting tube, and the sealing cover and the blood collection connecting tube are also spirally connected; after the first centrifugation at 300g-500g, the supernatant plasma obtained is directly extracted through the PRP storage tube to obtain 2-3 times platelet-rich plasma, which can be used directly for some diseases. When a higher concentration of platelets is required, the extracted PRP blood collection tube can be reversed and placed in a gravity centrifuge for a second centrifugation at 700-1200g to obtain the bottom layer of concentrated platelets. The upper layer of plasma without blood cells is transferred into a syringe through an external connecting tee, and the remaining part of the plasma is suspended in concentrated platelets to prepare concentrated platelet products for clinical use as needed.
[0015] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
