Description

Technical Field

[0001] The utility model relates to a protective cap for fixing an Ommaya capsule puncture and drainage device. Background Art

[0002] The Ommaya capsule is a minimally invasive ventricular drainage device. Once inserted, it is disconnected from the outside world and sealed beneath the scalp, allowing for frequent, frequent punctures for fluid withdrawal and intrathecal medication administration. Clinicians often puncture the anterior horn of the ventricle using a scalp needle, typically used for infusion, depending on the thickness of the scalp and the Ommaya capsule. A drainage tube is then connected from the scalp needle puncture point to the Ommaya capsule, creating the Ommaya capsule puncture and drainage device. However, current clinical practice often simply uses a disposable net head cover or no method of securing the Ommaya capsule puncture and drainage device. This not only affects aesthetics, but while this method secures the Ommaya capsule to the scalp needle puncture connection, the drainage tube and bag remain exposed, hindering patient mobility and hindering clinical nurses' ability to observe the puncture site. Furthermore, this disposable net head cover is not made of skin-friendly materials and is not reusable, significantly reducing the safety, comfort, and convenience of the entire puncture and drainage device. Utility Model Content

[0003] The purpose of the utility model is to provide a protective cap for fixing an Ommaya capsule puncture and drainage device, which helps to improve the safety, comfort and convenience of the entire puncture and drainage device.

[0017] In the figure: 10-elastic cap body, 11-annular elastic ring, 12-notch, 13-mask, 14-outer elastic non-woven fabric layer, 15-inner cotton material layer, 16-velcro, 17-pipe fixing sticker, 18-buckle, 20-fixing belt, 31-net bag, 32-connecting rope. DETAILED DESCRIPTION

[0018] To make the above features and advantages of the present invention more clearly understood, embodiments are given below with reference to the accompanying drawings for detailed description, but the present invention is not limited thereto.

[0019] refer to Figures 1 to 2

[0020] A protective cap for fixing an Ommaya capsule puncture and drainage device includes an elastic cap body 10 and a fixing strap 20. The elastic cap body is detachably connected to a mesh bag. An annular elastic ring 11 is provided at the edge of the bottom port of the elastic cap body. Notches 12 are respectively provided on both sides of the front of the elastic cap body. A covering piece 13 for covering the notch and having one side detachably connected to the elastic cap body is fixed on the elastic cap body. The two ends of the fixing strap are respectively connected to the two sides of the bottom of the elastic cap body.

[0021] In this embodiment, the elastic cap body is hemispherical and consists of an outer elastic non-woven fabric layer 14 and an inner cotton material layer 15. The inner cotton material layer is anti-allergic and skin-friendly, ensuring comfort. The outer elastic non-woven fabric layer and the elastic ring along the bottom edge of the cap body provide the elastic cap body with elasticity and flexibility, not only protecting the Ommaya capsule puncture connection from pressure but also accommodating patients with different head shapes. The inner cotton material layer also has anti-allergic properties, preventing allergic reactions when wearing the cap and increasing comfort.

[0022] In this embodiment, one side of the cover is connected to the edge of the notch of the elastic cap body via a Velcro 16, which makes it easy to lift the cover to expose the notch for needle insertion. In order to better fix the drainage tube, the elastic cap body is also provided with a pipe fixing patch 17 at the edge of the notch.

[0023] Usually, the Ommaya capsule puncture site is on the left and right sides of the anterior horn of the ventricle, so there is a cover on each side of the elastic cap body. On the one hand, it is convenient for clinical nurses to check the situation of the Ommaya capsule puncture site, and on the other hand, it can be used with the pipeline fixing patch to fix the drainage tube; at the same time, the size of the cap body can be determined by the size of the fitting surface of the mother and child surfaces of the Velcro, which helps to further adjust the size of the elastic cap body.

[0024] In this embodiment, in order to facilitate the connection of the fixing belt, buckles 18 are fixed on both sides of the bottom of the elastic cap body, and the two ends of the fixing belt are respectively wrapped around and connected with the buckles, or the two ends of the fixing belt are respectively provided with connection holes for the buckles to pass through, so as to achieve detachable connection.

[0025] In this embodiment, the fixing belt is made of a wide non-woven elastic material. The fixing belt can be removed through a buckle and is suitable for patients with different head shapes and sizes.

[0026] In this embodiment, the net bag includes a net bag 31 made of stretchable polyester mesh, and a connecting rope 32 for connecting with buckles is fixed on the net bag, so that the connecting rope is wrapped around one of the buckles to store an excessively long drainage tube and drainage bag in the net bag.

[0027] The mesh bag connection line can be positioned according to the Ommaya sac puncture site and is connected to the buckle for easy removal. When the Ommaya sac is connected to an external drainage device, the mesh bag can prevent the drainage tube and drainage line from being pulled, making it easier for patients to get out of bed.

[0028] If the present invention discloses or involves components or structural parts that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by integral molding using a casting process) (except where it is obviously not possible to use an integrated molding process).

[0029] In addition, unless otherwise stated, the terms used in any technical solution disclosed in the above-mentioned utility model to express positional relationships or shapes include states or shapes that are approximate, similar or close thereto.

[0030] Any component provided by the present invention can be assembled from multiple separate components, or can be a separate component manufactured by an integral forming process.

[0031] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention.
