Description

Technical Field

[0001] This utility model belongs to the field of neurosurgical ventricle technology and relates to a ventricle drainage tube fixation device, specifically a multi-size adaptable neurosurgical ventricle drainage tube anti-pressure fixation cap. Background Technology

[0002] Neurosurgery involving the ventricles primarily focuses on lesions that may occur within the ventricles, including tumors, inflammation, and hemorrhage. These lesions can obstruct the normal flow of cerebrospinal fluid, leading to increased intracranial pressure and other serious neurological dysfunctions. Therefore, neurosurgeons use craniocerebral surgery techniques and methods for diagnosis and treatment. After craniocerebral surgery, patients need to wear an elastic head cap to isolate the wound from harmful substances such as dust and bacteria in the external environment and accelerate wound healing.

[0003] Patent CN220558152U discloses a postoperative head cap that solves the problems of existing fixation devices being prone to falling off and failing to secure drainage tubes. It includes a hemispherical head cap with an opening facing downwards, a pressure-resistant neck strap at the lower rear of the head cap, a ring-shaped fixing strap at the lower end of the pressure-resistant neck strap, multiple fixing tubes evenly distributed along the circumference at the upper end of the head cap, a rectangular fixing shell at the upper end of the fixing tubes, a through hole coaxial with the fixing tubes and extending vertically at the upper end of the fixing shell, a rectangular push plate slidably connected inside the fixing shell, and a clamping hole extending vertically and communicating with the through hole on the push plate.

[0004] Patent CN208003238U discloses a medical ventricular drainage tube fixation device, including a first head fixation device and a second head fixation device. The first head fixation device is a partially spherical shell, and the second head fixation device is a mesh elastic fixation sleeve. The partially spherical shell includes a brim, a head protection area, and two postauricular fixation areas on both sides. The brim and the head protection area are rigid structures, and the brim and the head protection area are connected to form a half-hat shape. The head protection area has a first fixation hole in the middle and a left fixation hole and a right fixation hole on both sides, respectively. The postauricular fixation areas are connected to both sides of the head protection area, and the postauricular fixation areas extend to the left and right from both sides of the head protection area to form an arc-shaped structure.

[0005] Currently, postoperative head caps typically use an elastic mesh structure to completely cover the wound and the patient's head, and are secured to the patient's chin with elastic straps to prevent movement. However, the elastic mesh can easily put significant pressure on the wound, hindering rapid wound healing. Furthermore, the head appears slightly bulky when worn, and the elastic straps can easily leave pressure marks on the face, causing discomfort to the patient's face and ears. Therefore, there is a need to design a neurosurgical ventricular drainage tube fixation cap that is well-fitting and less likely to cause pressure marks. Summary of the Invention

[0052] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0053] Example 1: A multi-size adaptable anti-compression fixation cap for neurosurgical ventricular drainage tubes

[0054] refer to Figures 1 to 11 The structure of the multi-size adaptable neurosurgical ventricular drainage tube anti-pressure fixation cap provided in this embodiment mainly includes:

[0055] (I) Main Body

[0056] refer to Figures 1-4 The protective headgear 1 and the adjustable support structure 2 are used to connect the patient's head and the protective headgear 1. The protective headgear 1 is the main structure of the anti-pressure fixing cap and is placed on the patient's head. The headgear is made of medical non-woven fabric. The adjustable support structure 2 is used to connect the patient's head and the protective headgear 1 and is set on the inside of the protective headgear 1.

[0057] The adjustable support structure 2 includes two support rings 201. The support rings 201 are a first keel ring 2011 and a second keel ring 2012 with a cross-shaped semi-circular ring structure. The first keel ring 2011 and the second keel ring 2012 have a sewing hole 8 on the side facing the protective head cap 1. The first keel ring 2011 and the second keel ring 2012 are sewn and fixed to the protective head cap 1 by passing a sewing thread through the sewing hole 8. The first keel ring 2011 is above the second keel ring 2012.

[0058] Both the first keel hoop 2011 and the second keel hoop 2012 have two U-shaped cavities 9 on their inner sides, each filled with an airbag layer 202. Part of the airbag layer 202 fills the interior of the cavity 9, while a portion extends outside, gently contacting the patient's head. An inflation port 3 is located on the side of the first keel hoop 2011 and the second keel hoop 2012 facing the protective headgear 1, and this port is connected to the airbag layer 202. The protective headgear 1 has four through holes corresponding to the positions of the inflation ports 3, allowing for easy inflation of the airbag layer 202.

[0059] When the airbag is inflated through the air inlet 3, the airbag layer 202 will quickly inflate; the two support rings 201 are made of resin material with excellent strength and toughness, which can easily adapt to covering the patient's head, and can also adapt to certain deformation of the head circumference. In addition, the airbag layer 202 will fit the scalp to avoid the rings causing a foreign body sensation on the head.

[0060] (II) Adjusting the detailed construction of the support structure: directional adjustment between the two keel hoop rings

[0061] refer to Figures 5-7 A hollow sleeve 4 is fixedly installed at the top of the first keel hoop 2011, and a guide tube 203 is fixedly installed on the second keel hoop 2012. The guide tube 203 passes through the sleeve 4, that is, the second keel hoop 2012 is rotatably connected to the sleeve 4 of the first keel hoop 2011 through the guide tube 203, ensuring that the two hoops can rotate to a certain extent, which facilitates the folding and unfolding of the protective headgear 1.

[0062] The insertion tube 203 and the sleeve 4 are connected by a limiting member 204, which includes an engaging toothed ring 2041, a connecting rod 2042, and a magnetic ring 2043. The engaging toothed ring 2041 is fixed to the outside of the insertion tube 203. There are two connecting rods 2042, which are symmetrically and rotatably connected to the left and right sides of the sleeve 4. Each connecting rod 2042 has a two-section structure and is used to control the relative position of the magnetic rings 2043. A semi-circular magnetic ring 2043 is rotatably connected to one end of each of the two connecting rods 2042. The inner side of the two magnetic rings 2043 is provided with an inner tooth layer that matches the engaging toothed ring 2041. Figure 6 As can be seen in the image, the inner side of the drainage tube 203 is hollow and has a channel for the drainage tube to pass through. The drainage tube is led out through the patient's head wound and passes through the inner side of the drainage tube 203 to facilitate the drainage of fluid accumulated in the head wound.

[0063] The upper end of the protective headgear 1 has a through structure, and the sleeve 4, the through tube 203, and the limiting member 204 mentioned above are all located at this through point.

[0064] When the second keel hoop 2012 drives the threading tube 203 to rotate, the meshing toothed ring 2041 on the outside of the threading tube 203 will rotate synchronously. When wearing or stacking, it is necessary to prevent the second keel hoop 2012 from rotating. This is achieved by magnetically engaging the magnetic rings 2043 on the left and right sides of the sleeve 4. The inner toothed layer on the inner side of the magnetic ring 2043 engages with the meshing toothed ring 2041, thus restricting the rotation of the threading tube 203 and the second hoop 2012. The connecting rod 2042 has a two-stage rotating structure, which facilitates the adjustment of the direction of the magnetic ring 2043.

[0065] (III) Detailed Construction of Adjustment Support Structure: Drainage Tube Fixing Structure

[0066] refer to Figure 8Above the meshing toothed ring 2041, four slots are evenly opened through the inner wall of the through tube 203 at the same horizontal line. Each slot is fixedly connected to a through tube 5 with a convex structure on the outside of the through tube 203. The through tube 5 includes a first tube end 501 and a second tube end 502. One end of the first tube end 501 is connected to the slot, and the other end is integrally formed and fixedly connected to the second tube end 502. The first tube end 501 has a hollow tube wall structure, and the second tube end 502 has a non-hollow tube wall structure.

[0067] A tension rod 205 is fitted inside the tube 5. One end of the tension rod 205 extends to the outside of the second tube end 502 and has a small handle perpendicular to its length, which can be pulled or pushed. An arc-shaped clamp 206 is fixedly connected to the other end of the tension rod 205. The inner side of the arc-shaped clamp 206 has a threaded structure, which increases the friction between it and the drainage tube. The tension rod 205 and the arc-shaped clamp 206 can be manufactured as a single piece, or they can be connected by a combination of adhesive bonding and heat pressing. This connection method is existing technology and does not affect the overall structural design of this utility model. A total of four arc-shaped clamps 206 are arranged together to form a ring structure, through which the drainage tube is inserted. The four arc-shaped clamps 206 are not connected to each other, but are relatively close in position, forming a near-circular shape, and are used together to fix the drainage tube.

[0068] A first spring coil 6 is provided at the interlayer between the first tube end 501 and the tension rod 205. The length of the first spring coil 6 is sufficient to abut the arc-shaped clamp 206 without the application of external force. The diameter of the joint between the first tube end 501 and the second tube end 502 is smaller than the diameter of the first spring coil 6. The first spring coil 6 is confined inside the first tube end 501 and will not come out of the second tube end 502.

[0069] Specifically, in this embodiment, after the drainage tube is led out through the head, it is necessary to prevent the drainage tube from shaking in order to alleviate the patient's head wound discomfort. By pulling the tension rod 205 on the outside of the drainage tube 203, the tension rod 205 compresses the first spring coil 6. After releasing the tension rod 205, the first spring coil 6 returns to its original position and rebounds, causing the tension rod 205 to drive the arc-shaped clamp 206 to move towards the inner axis of the drainage tube 203. The arc-shaped clamp 206 clamps and adheres to the outside of the drainage tube, achieving a clamping effect and preventing the end of the drainage tube near the head wound from shaking or shifting.

[0070] (iv) Cable Bundle Assembly

[0071] refer to Figure 9 and Figure 10The protective headgear 1 has a drawstring 208 sewn around its lower inner side, with an inner layer that is a pouch-like structure made of medical non-woven fabric. A loop-shaped elastic drawstring 209 is provided around the inner layer of the drawstring 208. Both the protective headgear 1 and the drawstring 208 have perforations 7 on their front sides, and one end of the elastic drawstring 209 extends through the perforation 7 to the outer front side of the protective headgear 1.

[0072] An adjusting component 210 is sleeved on the outside of the elastic pull rope 209; the adjusting component 210 includes a ball groove block 2101, a second spring coil 2102, an adjusting ball 2103, and a pressure rod 2104. The second spring coil 2102 is fixedly connected to the inner wall of one side of the ball groove block 2101, and the adjusting ball 2103 is fixedly connected to the other end of the second spring coil 2102. The adjusting ball 2103 has a hole in the middle, through which the elastic pull rope 209 is inserted; the elastic pull rope 209 has a loop-shaped structure, with one side wrapped around the inside of the rope strap 208, and the other side passing through the through hole 7, and then passing out from the inside of the adjusting ball 2103 and the ball groove block 2101; the pressure rod 2104 is fixedly connected to the inner wall of the other side of the ball groove block 2101, and the pressure rod 2104 penetrates the inner wall of the ball groove block 2101 and extends to the outside of the ball groove block 2101.

[0073] By pressing the lever 2104, the lever 2104 compresses the second spring coil 2102, increasing the gap between the adjusting ball 2103 and the inner wall of the ball groove block 2101, facilitating the stretching and pulling of the elastic pull rope 209. At this time, the elastic pull rope 209 is pulled to stretch and tighten it, adjusting the fit between the protective cap 1 and the patient's head. When the lever 2104 is released, the second spring coil 2102 springs back and pushes the adjusting ball 2103 to press against the inner wall of the ball groove block 2101, thereby pressing the elastic pull rope 209 and restricting its movement. Thus, the size of the cap can be adjusted by stretching the elastic pull rope 209, and then the adjusting ball 2103 is used to press and restrict the elastic pull rope 209 from continuing to move.

[0074] (V) Mesh Fabric Layer Structure

[0075] refer to Figure 11 The protective headgear 1 has a mesh fabric layer 207 sewn into the inner top layer; the inner layer of the mesh fabric layer 207 is an antibacterial surface layer 2071, which is a blended structure of nano-silver antibacterial fiber and kapok fiber; the outer layer of the antibacterial surface layer 2071 is sewn with a breathable surface layer 2072, which is a blended structure of polyester fiber and hemp fiber.

[0076] In this embodiment, the nano-silver antibacterial fiber has excellent antibacterial effect. Combined with kapok fiber, it improves breathability and sweat-wicking performance, effectively ensuring the breathability of the head and avoiding the problem of anaerobic bacteria growth caused by sweat and heat in the wound area. The blend of polyester fiber and hemp fiber is used as the outer layer structure of the mesh fabric layer 207, which can improve the wear resistance of the mesh fabric layer 207 and maintain a certain breathability.

[0077] In summary, this multi-size adaptable neurosurgical ventricular drainage tube pressure-resistant fixation cap adapts to the patient's head shape through the first keel hoop 2011 and the second keel hoop 2012, supporting the cap structure to prevent excessive softness and adhesion to the wound site, which would reduce wound ventilation. At the same time, the air bladder layer 202 conforms to the scalp to improve the patient's head comfort. The drainage tube 203 passes through the drainage tube, and the first spring coil 6 restricts the movement range of the tension rod 205. The arc-shaped clip 206 of the tension rod 205 clamps and adheres to the outside of the drainage tube, preventing the drainage tube from shaking. To prevent discomfort caused by movement to the patient's head wound, the headgear is made of an antibacterial outer layer 2071 made of a blend of nano-silver antibacterial fiber and kapok fiber, and a breathable outer layer 2072 made of a blend of polyester fiber and hemp fiber. This further improves the antibacterial and breathable effect of the headgear, preventing sweat from accumulating on the head and promoting wound healing. The headgear size can be adjusted according to the patient's head circumference by stretching the elastic cord 209. At the same time, the second spring ring 2102 pushes the adjusting ball 2103 to press the elastic cord 209, preventing the elastic cord 209 from moving after adjustment and achieving a limiting effect.
