Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical imaging examination, and in particular to a protective cover for a connectable and fixed sponge device used in CT scans. Background Technology
[0002] In medical imaging diagnosis, CT (computed tomography) is a commonly used examination method. Patients usually need to lie on the scanning table, keeping their head and eye sockets fixed in position to obtain high-quality image data. However, for uncooperative patients, especially the elderly and children, auxiliary tools are needed to help them maintain stability and the correct position during CT scans. When fixing the head and eye sockets during a CT scan, the patient should lie supine on the examination table with their head inserted into the headrest groove and their chin slightly tucked so that the canthal line is perpendicular to the table surface.
[0003] Therefore, the current method is to gently fill the gap between the head and the head frame with a fixation sponge plug, pressing symmetrically on both sides until the distance between the external auditory canal and the bed surface is equal, ensuring that the midsagittal plane coincides with the midline of the bed. The custom-made fixation sponge is inserted, which is as stable as if the skull is supported by both hands, and the elastic support avoids pressure, so that the head is completely still as if it is wrapped in an invisible cocoon throughout the scanning process.
[0004] However, if there is no effective connection mechanism, the two fixing sponges can easily fall off when the patient gets up to leave after the scan, which does not meet the requirements for infection control and causes safety hazards such as inconvenience and even hospital infection. Utility Model Content
[0005] The present invention aims to at least partially solve one of the technical problems in the aforementioned technologies. Therefore, the purpose of this invention is to provide a protective sleeve for fixing a sponge pad to a relative position on a CT examination bed.
[0006] To achieve the above objectives, embodiments of this utility model provide a protective sleeve for a connectable and fixed sponge device used in CT scans, comprising:
[0007] The protective sleeve is made of flexible material and has an opening that can be opened and closed. The retaining sponge is inserted into the protective sleeve through the opening, and the protective sleeve wraps around the retaining sponge.
[0008] A traction rope, positioned away from the opening of the protective sleeve, connects the two protective sleeves together.
[0009] The lug has a guide hole for the traction rope to pass through, a limiting member to restrict the sliding of the traction rope relative to the guide hole, and a clamping member to hold it on the CT examination table.
[0010] The clamps fix the hanging ears to both sides of the CT bed. The traction rope passes through the guide hole and is fixed by the limiting component, so that when the protective cover containing the fixing sponge hangs down, it maintains a constant distance from the ground.
[0011] The limiting component includes a fixed plate and a movable plate. Under the action of external force, the movable plate moves relative to the fixed plate to form a gap. The traction rope passes through the gap. When the external force is removed, the gap decreases and the traction rope is clamped.
[0012] The present invention can effectively prevent the sponge pad from falling off when the patient gets up while ensuring patient comfort. The protective cover is easy to replace, ensuring that each patient uses a new protective cover, thereby meeting hospital infection control requirements and reducing the occurrence of hospital infections.
[0013] In addition, the connectable and fixed sponge device protective sleeve for CT scanning proposed in the above embodiments of this utility model may also have the following additional technical features:
[0014] Optionally, the traction rope between the two loops has an elastic section.
[0015] Optionally, the ear loops are integrally molded.
[0016] Optionally, the movable piece is embedded in the corresponding hole formed by the fixed piece, and the movable piece and the fixed piece are on the same plane. When an external force is applied to the fixed piece, the movable piece deviates from the plane where the fixed piece is located.
[0017] Furthermore, there is a gap between the movable plate and the fixed plate, and the gap width is smaller than the cross-sectional diameter of the traction rope.
[0018] Furthermore, the free end of the movable piece extends into the corresponding long groove formed by the fixed piece.
[0019] Optionally, the side of the movable piece facing the traction rope may be raised to form several anti-slip points. Attached Figure Description

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0028] This utility model achieves the goals of preventing the sponge from falling off, improving hygiene and safety, and enhancing ease of operation and comfort through its traction rope connection design, clean and hygienic protective sleeve that wraps the fixed sponge, easy-to-operate connection method, and stable support structure.
[0029] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.
[0030] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0031] While existing fixed sponge pads can help stabilize patients to some extent, the two pads are prone to falling off when the patient gets up. This not only increases the workload of medical staff but also risks injury to the patient from accidental contact. Furthermore, the frequent falling of the sponge pads can lead to hygiene problems, increasing the cost and time required for disinfection and cleaning.
[0032] Figures 1 to 5 According to an embodiment of the present utility model, a protective sleeve for a connectable and fixed sponge device for CT scanning includes: a protective sleeve 1, made of flexible material, having an openable and sealable opening, a fixed sponge being inserted into the protective sleeve 1 through the opening, and the protective sleeve 1 wrapping the fixed sponge; and a traction rope 2, located at a position away from the opening of the protective sleeve 1, connecting two protective sleeves 1 together.
[0033] The purpose of the above design is to prevent the sponges from falling: the sponge fixing device in this solution connects the two sponges together via a traction rope 2 and a protective sleeve 1, ensuring that the sponges will not fall when the patient gets up. This design significantly reduces the workload of medical staff and also reduces the risk of injury to patients from accidentally touching a fallen sponge.
[0034] Furthermore, it enhances hygiene and safety: Because the sponge won't easily fall off, the need for frequent disinfection and cleaning is reduced, helping to maintain a good medical environment and lowering the risk of infection. Using non-woven fabric to make the traction rope 2 and protective sleeve 1 allows for one bag per patient, improving the overall hygiene level of the medical facility, increasing patient safety and comfort, and helping patients recover faster.
[0035] The protective case 1 is set up in the following way: Figure 5 The drawstring closure shown can also be achieved using Velcro.
[0036] Furthermore, this solution is easy to operate: the device has a simple structure and is easy to use, making it particularly suitable for uncooperative patients. Caregivers can easily assist patients with pre- and post-CT scan preparations, greatly simplifying the procedure and improving efficiency.
[0037] The device also prioritizes comfort and stability: the soft, comfortable foam padding conforms to the patient's head and eye sockets, minimizing discomfort. During CT scans, the foam pads provide stable support, ensuring image quality.
[0038] In some embodiments, the traction rope 2 can be broken in the middle and connected by means such as a direct knot, or by using Velcro, plastic snaps, etc. The purpose of doing so is to reduce the length of the entire structure by breaking it apart, thereby reducing the problem of tangling when storing and retrieving it.
[0039] In some embodiments, the traction rope 2 between the two loops 3 has an elastic section. The purpose of this design is to provide a margin of error so that when the length of the traction rope 2 is not adjusted to the correct position, the patient will feel uncomfortable due to the pressure of the rope when lying down.
[0040] The hanging ear 3 has a guide hole 31 for the traction rope 2 to pass through, a limiting member 32 to restrict the sliding of the traction rope 2 relative to the guide hole 31, and a clamping member 33 to hold it on the CT examination table; the clamping member 33 fixes the hanging ear 3 to both sides of the CT table, the traction rope 2 passes through the guide hole 31 and is fixed by the limiting member 32, so that when the protective cover 1 containing the fixing sponge hangs down, it maintains a constant distance from the ground.
[0041] The limiting member 32 includes a fixed piece 321 and a movable piece 322. Under the action of external force, the movable piece 322 moves relative to the fixed piece 321 to form a gap. The traction rope 2 passes through the gap. When the external force is removed, the gap decreases and the traction rope 2 is clamped.
[0042] The protective sleeve 1, which contains a fixing sponge, will naturally fall to both sides after the patient gets up. If there is no limiting component 32, the traction rope 2 in the middle will be naturally tightened, and it may slip down to one side. Setting the limiting component 32 can solve this problem and play the role of tightening the protective sleeve 1.
[0043] Optionally, the ear loops are molded as a single piece for easy manufacturing.
[0044] One approach is to embed the movable piece 322 within the corresponding hole formed by the fixed piece 321. The movable piece 322 and the fixed piece 321 are on the same plane. When an external force is applied to the fixed piece 321, the movable piece 322 deviates from the plane of the fixed piece 321. Furthermore, there is a gap between the movable piece 322 and the fixed piece 321, the width of which is smaller than the cross-sectional diameter of the traction rope 2. The advantage of this approach is that the traction rope 2 can pass through the gap between the movable piece 322 and the fixed piece 321. Therefore, the lug 3 can be flexibly secured at the headrest of the CT bed without requiring the traction rope 2 and the two lugs 3 to be on the same straight line. Since the traction rope 2 is made of braided material, it will deform when compressed. This method effectively restricts the sliding of the traction rope 2.
[0045] Another option is to extend the free end of the movable piece 322 into the corresponding long groove formed by the fixed piece 321. In this option, the traction rope 2 is embedded along the long groove and pressed tightly by the movable piece 322. Unlike the previous option, this option can press the traction rope 2 tighter and make it less likely to slip. However, the two lugs 3 need to be on the same straight line as the traction rope 2.
[0046] Optionally, the movable piece 322 has a protrusion on the side facing the traction rope 2 to form several anti-slip points, which can effectively improve the fixation of the traction rope 2.
[0047] In summary, this solution, through its traction rope connection design (2 units), clean and hygienic protective sleeve (1 unit), soft and comfortable sponge material, easy-to-operate connection method, and sturdy hanging ear (3 unit) fixing structure, achieves the goals of preventing sponge from falling off, improving hygiene and safety, and enhancing operational convenience and comfort. These technical measures work together to provide patients with a safer and more comfortable CT scan experience, while also providing medical staff with a more efficient working environment.
