Description

Technical Field

[0001] This utility model belongs to the field of anesthesia medical device technology, and more specifically, it relates to a disposable epidural anesthesia kit. Background Technology

[0002] Epidural anesthesia refers to epidural space block anesthesia, which involves injecting local anesthetic into the epidural space to block the spinal nerve roots, temporarily paralyzing the area they innervate. This is called epidural space block anesthesia, or simply epidural block. Existing disposable epidural anesthesia kits have difficulty turning their head when encountering obstacles, which can damage blood vessels or nerves. At the same time, the drug is only delivered from the head, resulting in concentrated drug diffusion and a poor anesthetic plane. Therefore, disposable epidural anesthesia kits have been proposed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a disposable epidural anesthesia kit. The head end is designed with elasticity and includes a head end component and multiple dispensing holes. This solves the problems mentioned in the background art, such as the head end being difficult to turn flexibly when encountering obstacles, which could damage blood vessels or nerves. Additionally, since the medication is only dispensed from the head end, the drug diffusion is relatively concentrated, resulting in a poor anesthetic plane.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a disposable epidural anesthesia kit, comprising an epidural anesthesia catheter, the epidural anesthesia catheter having a transparent section and an opaque section, graduation lines on the outer side of the epidural anesthesia catheter, a spiral locking connector fixed at one end of the epidural anesthesia catheter, a spiral spring steel wire on the inner side of the epidural anesthesia catheter, a sleeve fixed at the other end of the epidural anesthesia catheter, a rotating groove on the inner side of the sleeve, a rotating ring rotatably connected to the inner side of the rotating groove, a head end piece fixed to the inner side of the rotating ring, the head end piece comprising a first head end block and a second head end block, a first connecting groove having an inner diameter smaller than the inner diameter of the epidural anesthesia catheter, a second connecting groove having an inner side of the second head end block, and a third connecting groove having an outer side of the second head end block.

[0005] As a preferred embodiment of this utility model, the epidural anesthesia catheter has multiple discharge holes on its outer side near the tip, and the multiple discharge holes are arranged at equal intervals.

[0006] As a preferred embodiment of this utility model, the length of the helical spring wire is the same as the length of the epidural anesthesia catheter, and the outer diameter of the helical spring wire is the same as the inner diameter of the epidural anesthesia catheter.

[0007] As a preferred embodiment of this utility model, the first head end block has a cylindrical structure, and the second head end block has a spherical structure.

[0008] As a preferred embodiment of this invention, the interior of the first connecting groove is connected to the interior of the epidural anesthesia catheter.

[0009] As a preferred embodiment of this utility model, the interior of the second connecting groove is connected to the interior of the first connecting groove.

[0010] As a preferred embodiment of this utility model, the interior of the third connecting groove is connected to the interior of the second connecting groove.

[0011] This invention provides a disposable epidural anesthesia kit, which has the following beneficial effects:

[0012] 1. This disposable epidural anesthesia kit features an epidural anesthesia catheter with a flexible tip design. During insertion, the catheter bends when encountering obstacles such as blood vessels, nerves, or the dura mater, allowing it to slide over the tissue. This reduces the risk of damage to blood vessels, nerves, or the dura mater caused by the rigid tip of ordinary catheters. Furthermore, the tip is equipped with a tip piece. Since the tip piece is rotatably connected to the rotating groove of the sleeve via a rotating ring, and the second tip block within the tip piece is spherical and has a rounded structure, it can rotate flexibly when encountering obstacles, further reducing the risk of damage to blood vessels, nerves, or the dura mater. This solves the problem of the tip being unable to flexibly turn when encountering obstacles, thus preventing damage to blood vessels or nerves.

[0013] 2. In this disposable epidural anesthesia kit, the medication is injected into the epidural anesthesia catheter through a spiral locking connector. Then, it is injected into the tissue sequentially through the first connecting groove, the second connecting groove, and the third connecting groove. During this process, multiple outlet holes on the outside of the epidural anesthesia catheter can simultaneously release medication, increasing the flow rate of the injected medication. This solves the problem that only the tip of the catheter releases medication, resulting in concentrated drug diffusion and poor anesthesia coverage. Attached Figure Description

[0019] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0020] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figures 1 to 4This utility model provides a technical solution: a disposable epidural anesthesia kit, including an epidural anesthesia catheter 1, the epidural anesthesia catheter 1 including a transparent section 101 and an opaque section 102, the epidural anesthesia catheter 1 having a scale line 2 on its outer side, a spiral locking connector 3 fixed at one end of the epidural anesthesia catheter 1, a spiral spring steel wire 4 on the inner side of the epidural anesthesia catheter 1, a sleeve 5 fixed at the other end of the epidural anesthesia catheter 1, a rotating groove 6 opened on the inner side of the sleeve 5, a rotating ring 7 rotatably connected to the inner side of the rotating groove 6, a head end piece 8 fixed on the inner side of the rotating ring 7, the head end piece 8 including a first head end block 801 and a second head end block 802, the first head end block 801 having a first connecting groove 803 inside, the inner diameter of the first connecting groove 803 being smaller than the inner diameter of the epidural anesthesia catheter 1, the second head end block 802 having a second connecting groove 804 inside, and a third connecting groove 805 opened on the outer side of the second head end block 802;

[0023] The insertion depth can be observed through the graduation lines 2 of the epidural anesthesia catheter 1. The transparent section 101 allows for the flow of medication and blood. The epidural anesthesia catheter 1 is equipped with a spiral spring wire 4 to support the catheter body, ensuring unobstructed medication flow and preventing kinking, knotting, or breakage. The epidural anesthesia catheter 1 has an elastic tip design, which bends when encountering obstacles such as blood vessels, nerves, or the dura mater during insertion, thus sliding over the tissue. This reduces the risk of damage to blood vessels, nerves, or the dura mater from the rigid tips of ordinary catheters. Additionally, a tip piece 8 is provided at the tip. The rotating ring 7 is rotatably connected to the rotating groove 6 of the sleeve 5, and the second head end block 802 in the head end piece 8 is spherical and has a rounded structure. The rounded second head end block 802 can rotate flexibly when encountering obstacles, reducing the risk of damaging blood vessels, nerves or dura mater and other tissues. At the same time, the inner diameter of the first connecting groove 803 in the first head end block 801 is smaller than the inner diameter of the epidural anesthesia catheter 1, which can avoid the risk of leakage of the helical spring wire 4. Through the above process, the problem of the head end being difficult to turn flexibly when encountering obstacles is solved, thereby damaging blood vessels or nerves and other tissues.

[0024] Furthermore, multiple fluid outlet holes 9 are provided on the outer side of the epidural anesthesia catheter 1 near the head end piece 8. The multiple fluid outlet holes 9 are arranged at equal intervals. The length of the helical spring wire 4 is the same as the length of the epidural anesthesia catheter 1, and the outer diameter of the helical spring wire 4 is the same as the inner diameter of the epidural anesthesia catheter 1. The first head end piece 801 has a cylindrical structure, the second head end piece 802 has a spherical structure, the interior of the first connecting groove 803 is connected to the interior of the epidural anesthesia catheter 1, the interior of the second connecting groove 804 is connected to the interior of the first connecting groove 803, and the interior of the third connecting groove 805 is connected to the interior of the second connecting groove 804.

[0025] The medication is injected into the epidural anesthesia catheter 1 through the spiral locking connector 3, and then sequentially injected into the tissue through the first connecting groove 803, the second connecting groove 804 and the third connecting groove 805. During this process, multiple outlet holes 9 on the outside of the epidural anesthesia catheter 1 can simultaneously dispense medication, increasing the flow rate of the injected medication and thus solving the problem that only the tip of the catheter dispenses medication, resulting in concentrated drug diffusion and poor anesthesia plane.

[0026] The specific usage and function of this embodiment: The epidural anesthesia catheter 1 allows observation of the insertion depth via the graduation lines 2. The transparent section 101 allows for the flow of medication and blood. The epidural anesthesia catheter 1 is equipped with a spiral spring wire 4 to support the catheter body, ensuring unobstructed medication flow and preventing kinking, knotting, or breakage. The epidural anesthesia catheter 1 features an elastic tip design, which bends when encountering obstacles such as blood vessels, nerves, or the dura mater during insertion, allowing it to slide over tissues. This reduces the risk of damage to blood vessels and nerves caused by the rigid tip of ordinary catheters. To mitigate the risks to tissues such as blood vessels, nerves, or the dura mater, the head end is equipped with a head end piece 8. Since the head end piece 8 is rotatably connected to the rotating groove 6 of the sleeve 5 via the rotating ring 7, and the second head end block 802 in the head end piece 8 has a spherical structure, the rounded second head end block 802 can rotate flexibly when encountering obstacles, reducing the risk of damage to tissues such as blood vessels, nerves, or the dura mater. At the same time, the inner diameter of the first connecting groove 803 in the first head end block 801 is smaller than the inner diameter of the epidural anesthesia catheter 1, which can avoid the risk of leakage of the helical spring wire 4.

[0027] The medication is injected into the epidural anesthesia catheter 1 through the spiral locking connector 3, and then sequentially injected into the tissue through the first connecting groove 803, the second connecting groove 804 and the third connecting groove 805. During this process, multiple outlet holes 9 on the outside of the epidural anesthesia catheter 1 can simultaneously dispense medication, increasing the flow rate of the injected medication.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
