Description

Technical Field

[0001] This application belongs to the technical field of medical assistive devices, and more specifically, relates to a lumbar puncture postural restraint garment. Background Technology

[0002] Lumbar puncture is a common medical procedure used to diagnose and treat various neurological disorders. During the procedure, the patient needs to maintain a flexed, knee-hugging position to ensure the intervertebral space is fully open, facilitating the insertion of the needle. However, many patients, due to discomfort or physical limitations, find it difficult to maintain this position for extended periods, leading to restricted opening of the intervertebral space and increasing the difficulty and risk of the puncture.

[0003] Currently, most restraint devices used to assist in fixing the patient's position use a single-direction restraint strap to fix the patient's torso. However, they cannot effectively limit the patient's lower limb flexion angle and hip joint range of motion. This makes it easy for the patient to retract their position during the puncture process due to muscle relaxation or pain response, resulting in a reduction in the exposed area of ​​the lumbar intervertebral space, which is not conducive to the operation of medical staff. Utility Model Content

[0004] The purpose of this application is to provide a lumbar puncture postural restraint garment to overcome the shortcomings of existing lumbar puncture auxiliary fixation devices in terms of poor patient postural restraint.

[0005] To achieve the above objectives, this application provides a lumbar puncture positioning restraint garment, comprising a restraint garment body and at least two sets of fixing straps; the restraint garment body is used to be worn on the upper body of the patient, the restraint garment body has at least two connecting parts arranged along the extension direction of the restraint garment body, each fixing strap corresponds to each of the connecting parts, and the fixing strap is connected to the corresponding connecting part;

[0006] The fixing strap includes a first connecting strap and a second connecting strap; one end of the first connecting strap is connected to the left side of the corresponding connecting part, and the other end is provided with a first buckle; one end of the second connecting strap is connected to the right side of the corresponding connecting part, and the other end is provided with a second buckle; after either the first connecting strap or the second connecting strap passes around the patient's popliteal fossa, the first buckle can be plugged and unplugged into the second buckle to fix the patient in a left lateral decubitus position.

[0007] In some embodiments, the fixing strap further includes a flexible pad disposed on the first connecting strap or the second connecting strap, for padding the popliteal fossa when the first connecting strap or the second connecting strap is connected to bypass the patient's popliteal fossa.

[0008] In some embodiments, the flexible pad is a sponge sleeve that is slidably fitted onto the first connecting strip or the second connecting strip.

[0009] In some embodiments, the first buckle includes: a housing, a locking member, and a first elastic member; the housing has a locking chamber and an insertion port communicating with the locking chamber and an external space, and the first connecting strip is connected to the housing; the locking member is disposed in the locking chamber, and the locking member includes a main body and a limiting part protruding from one side of the main body, the main body is slidably connected to the housing along an opening direction perpendicular to the insertion port, and the limiting part is provided with a guide slope on the side facing the insertion port; the first elastic member is connected between the main body and the housing;

[0010] The second buckle includes a buckle body with a locking hole. The buckle body can be inserted into the locking chamber through the insertion port. After entering the locking chamber, the buckle body can abut against the guide slope and push the locking member to slide so that the buckle body passes the limiting part. When the position of the locking hole corresponds to the position of the limiting part, the first elastic member drives the locking member to reset and the limiting part is engaged in the locking hole.

[0011] In some embodiments, the housing further has an opening communicating with the locking chamber and the external space, the opening direction of which is perpendicular to the opening direction of the insertion port;

[0012] The locking component also includes an unlocking part connected to the main body, the unlocking part being slidably embedded in the cavity.

The push rod is slidably connected to the locking chamber, and the sliding direction of the push rod is parallel to the opening direction of the insertion port. The push rod is located on the side of the limiting portion facing away from the insertion port, and the second elastic member is connected between the push rod and the housing to generate a restoring force when the push rod moves away from the limiting portion.

[0014] After the buckle body passes the limiting part, it abuts against the push rod. The second elastic element applies a reaction force to the buckle body through the push rod, so that the buckle body tends to move towards the outside of the insertion port.

[0015] In some embodiments, the first buckle further includes a first adjustment buckle disposed on the side of the housing opposite to the insertion port, the first adjustment buckle having at least two parallel and spaced-apart first adjustment slots, and the first connecting strap being wound around the two first adjustment slots;

[0037] Reference Figure 1 This application provides a lumbar puncture positioning restraint garment, including a restraint garment body 100 and at least two sets of fixing straps 200. The restraint garment body 100 is worn on the patient's upper body and has at least two connecting parts arranged along the extension direction of the restraint garment body 100. Each fixing strap 200 corresponds to a connecting part and is connected to the corresponding connecting part. The fixing strap 200 includes a first connecting strap 210 and a second connecting strap 220; one end of the first connecting strap 210 is connected to the left side of the corresponding connecting part, and the other end is provided with a first buckle 230; one end of the second connecting strap 220 is connected to the right side of the corresponding connecting part, and the other end is provided with a second buckle 240. The first buckle 230 can be inserted and removed from the second buckle 240.

[0038] The restraint garment body 100 refers to the clothing structure worn on the patient's upper body. It can be made of breathable and relatively strong fabric, such as nylon or cotton. The shape of the restraint garment body 100 is adapted to fit the patient's upper body to ensure comfort and effective restraint. In one example, the restraint garment body 100 has a collar 101 and cuffs 102. The collar 101 is adapted to the patient's neck size, and the cuffs 102 are adapted to the patient's arms, allowing the arms to extend through the cuffs 102, thus achieving the purpose of wearing the restraint garment on the patient's upper body.

[0039] Furthermore, the restraint garment body 100 has an opening and closing mechanism on one side, and a fixing structure is provided at the opening and closing point. The opening and closing design on one side allows the patient to wear the garment without fully slipping it on. The fixing structure at the opening and closing point closes after wearing, and the tightness of the fixing structure can be adjusted to fit different body shapes. The opening and closing structure can be located on any side of the restraint garment body 100. In this embodiment, the opening and closing structure is located on the front of the restraint garment body 100 and extends downwards from the neckline 101 to facilitate wearing by the patient. The fixing structure can be Velcro, snaps, straps, or zippers, etc. In this embodiment, multiple snaps 103 are provided at the opening and closing structure, and the multiple snaps 103 are arranged at intervals along the extension direction of the opening and closing structure.

[0040] The connecting parts refer to the attachment positions on the restraint garment body 100 for setting the fixing straps 200, and can be specifically set according to the usage of the fixing straps 200. In this embodiment, the connecting parts include a shoulder connecting position 100a and a chest connecting position 100b. The shoulder connecting position 100a is located on the restraint garment body 100 corresponding to the human shoulder, and the chest connecting position 100b is located on the restraint garment body 100 corresponding to the human chest.

[0041] The restraint strap 200 is a band-like component used to restrict the patient's postural movements. It is used to wrap around the patient's popliteal fossa and restrict the patient's position by forming a restraining force. There should be no fewer than two restraint straps 200 to limit the patient's lower limbs in at least two directions, thereby improving the stability of the postural restraint.

[0042] In this embodiment, there are two fixing straps 200, including a shoulder fixing strap 200a and a chest fixing strap 200b. The shoulder fixing strap 200a is located at the shoulder connection position 100a of the restraint garment body 100, and the chest fixing strap 200b is located at the chest connection position 100b of the restraint garment body 100. (Refer to...) Figure 2 When in use, the shoulder fixation strap 200a, after passing around the popliteal fossa, can restrict forward or backward shoulder tilting; the chest fixation strap 200b, after passing around the popliteal fossa, can restrict trunk twisting. Because both the shoulder and chest are restrained by the fixation straps 200, the stability of the patient's upper body is enhanced, the lumbar intervertebral space is fully exposed in the left lateral decubitus position, and the puncture operation space is guaranteed.

[0043] The following description of the structure of the chest fixation strap 200b is used as an example. It is understood that the following description of the structure of the chest fixation strap 200b also applies to the shoulder fixation strap 200a.

[0044] Reference Figure 1 , Figure 3 and Figure 4The chest fixation strap 200b includes a first connecting strap 210 and a second connecting strap 220. The first connecting strap 210 and the second connecting strap 220 are strip-shaped structures extending from the left and right sides of the connection part, respectively. Both the first connecting strap 210 and the second connecting strap 220 can be made of fabrics such as nylon cloth, cotton cloth or elastic cloth, and are used to wrap around the popliteal fossa and form a closed constraint by inserting the first buckle 230 and the second buckle 240.

[0045] The first connecting strap 210 can be connected to the restraint garment body 100 by sewing, Velcro, or snap fasteners to ensure a stable connection. In this embodiment, two fixing fabric pieces 104 are sewn onto the chest connection position 100b of the restraint garment body 100. The end of the first connecting strap 210 facing the restraint garment body 100 is sandwiched between the two fixing fabric pieces 104 and sewn to them to improve the strength of the connection between the first connecting strap 210 and the restraint garment body 100. The second connecting strap 220 can also be fixedly connected to the other chest connection position 100b of the restraint garment body 100 using the same method, which will not be described in detail in this embodiment.

[0046] The first buckle 230 and the second buckle 240 refer to the locking devices used to connect the two fixing straps 200. Specifically, they can be implemented using a male and female buckle structure made of plastic or metal, and are used to quickly fix or release the restraints on the patient's lower limbs.

[0047] Reference Figure 5 , Figure 6 and Figure 7 In this embodiment, the first buckle 230 includes a housing 231, a locking member 232, and a first elastic member 233. The housing 231 has a locking chamber 2311 and an insertion port 2312 communicating with the locking chamber 2311 and the external space. A first connecting band 210 is connected to the housing 231. The locking member 232 is disposed in the locking chamber 2311 and includes a main body 2321 and a limiting part 2322 protruding from one side of the main body 2321. The main body 2321 is slidably connected to the housing 231 along the opening direction perpendicular to the insertion port 2312. The limiting part 2322 is provided with a guide slope on the side facing the insertion port 2312. The first elastic member 233 is connected between the main body 2321 and the housing 231.

[0048] The housing 231 is a structural component used to install and house the locking member 232 and other components. It can be made of materials such as plastic or metal and possesses sufficient strength and rigidity to support the movement of the locking member 232 and maintain the stability of the locked state. The shape and size of the housing 231 can be designed according to the structure and usage requirements of the locking member 232 to ensure that the locking member 232 can slide smoothly within the housing 231. In this embodiment, the housing 231 has a rectangular structure, and the insertion port 2312 is located at one of the extended ends of the housing 231.

[0049] The insertion port 2312 penetrates the side wall of the housing 231, allowing a portion of the second buckle 240 to enter the locking chamber 2311 through the insertion port 2312 for locking connection with the locking member 232. The shape and size of the insertion port 2312 can match the shape of the second buckle 240 to ensure that the second buckle 240 can be smoothly inserted into the locking chamber 2311 and form a stable locking state with the locking member 232. In this embodiment, the insertion port 2312 is a rectangular structure, and its width is slightly larger than the width of the second buckle 240 to facilitate the insertion and removal of the second buckle 240.

[0050] The locking member 232 is used to connect and cooperate with the second latch 240 that enters the locking chamber 2311 to achieve the locking of the first latch 230 and the second latch 240. In the locking member 232, the main body 2321 is the main structural part of the locking member 232, which is used to support the limiting part 2322 and slides in connection with the housing 231.

[0051] In this embodiment, the main body 2321 is a rectangular plate structure disposed within the locking chamber 2311. Figure 5 In the indicated state, the main body 2321 is located below the insertion port 2312. A guide post protrudes from the bottom of the main body 2321, and a guide cylinder is provided on the inner wall of the housing 231. The guide post is slidably embedded in the guide cylinder, allowing the main body 2321 to slide within the locking chamber 2311 in a direction perpendicular to the opening of the insertion port 2312. A limiting part 2322 protrudes from the upper surface of the main body 2321 and is used to form a limiting engagement with the buckle body 241 after the second buckle 240 is inserted. The limiting part 2322 is inclined on one side of the surface facing the insertion port 2312 to form a guide slope. The angle between the guide slope and the horizontal plane can be 45° to 60°.

[0052] The first elastic element 233 is an elastic component connected between the main body 2321 and the housing 231. In this embodiment, the first elastic element 233 is a cylindrical helical spring and is installed inside the guide cylinder. When the main body 2321 moves downward, the first elastic element 233 is compressed to generate a resetting force that drives the main body 2321 to move upward and reset.

[0053] In this embodiment, the second buckle 240 includes a buckle body 241, which has a locking hole 2411. The buckle body 241 is the part used to connect and cooperate with the locking member 232 in the first buckle 230. The shape and size of the buckle body 241 can match the shape of the insertion port 2312 so that a part of the buckle body 241 can enter the insertion port 2312 and penetrate into the locking chamber 2311 to cooperate with the locking member 232. The locking hole 2411 is a hole for the limiting part 2322 to pass through so as to achieve a locking connection with the locking member 232.

[0054] When the first buckle 230 and the second buckle 240 are connected, one end of the buckle body 241 of the first buckle 230 can be inserted into the locking chamber 2311 through the insertion port 2312. After the buckle body 241 enters the locking chamber 2311, it abuts against the guide slope of the limiting part 2322. The guide slope converts the horizontal thrust of the buckle body 241 into a vertical thrust, thereby pushing the locking member 232 to move downward and compressing the first elastic member 233. The limiting part 2322 gradually moves to below the insertion port 2312, so that the buckle body 241 can pass over the limiting part 2322. After the buckle body 241 is inserted into the locking position, when the position of the locking hole 2411 corresponds to the position of the limiting part 2322, the first elastic member 233 drives the locking member 232 to reset and the limiting part 2322 to be inserted into the locking hole 2411, restricting the buckle body 241 from being pulled out of the insertion port 2312, thereby realizing the locking function of the first buckle 230 and the second buckle 240.

[0055] Furthermore, the housing 231 also has a cavity 2313 that connects the locking chamber 2311 to the external space, and the opening direction of the cavity 2313 is perpendicular to the opening direction of the insertion port 2312. The locking member 232 also includes an unlocking part 2323 connected to the main body 2321, and the unlocking part 2323 is slidably embedded in the cavity 2313.

[0056] The cavity 2313 is a groove structure penetrating the side wall of the housing 231, used to install and accommodate the unlocking part 2323. The unlocking part 2323 is connected to the main body 2321 and is embedded in the cavity 2313. The patient can drive the entire locking member 232 to move through the unlocking part 2323, thereby unlocking the first latch 230 and the second latch 240, which are in the connected state. The shape and size of the cavity 2313 and the unlocking part 2323 are matched so that the unlocking part 2323 can slide smoothly within the cavity 2313. In this embodiment, the cavity 2313 is a rectangular groove structure, formed on one side surface of the housing 231 in the width direction. The unlocking part 2323 is a rectangular plate structure, with one side surface of the unlocking part 2323 connected to the main body 2321 and the other side surface exposed at the cavity 2313 for easy operation by the patient. In addition, it should be noted that the side of the unlocking part 2323 facing the insertion port 2312 has a certain gap between the limiting part 2322 and the main body part 2321, so that the buckle 241 can be smoothly inserted into the locking chamber 2311 through the gap, avoiding interference with the movement of the buckle 241.

[0057] Specifically, when unlocking the first buckle 230 and the second buckle 240, the patient can push the unlocking part 2323 to drive the locking member 232 to move in a direction perpendicular to the insertion port 2312, thereby causing the limiting part 2322 to exit from the locking hole 2411, and then the buckle body 241 can be pulled out from the insertion port 2312, so that the first buckle 230 and the second buckle 240 are separated, thereby relieving the restraint on the patient's lower limbs.

[0058] Furthermore, the first latch 230 also includes a push rod 234 and a second elastic element 235. The push rod 234 is slidably connected within the locking chamber 2311, and the sliding direction of the push rod 234 is parallel to the opening direction of the insertion port 2312. The push rod 234 is located on the side of the limiting portion 2322 facing away from the insertion port 2312. The second elastic element 235 is connected between the push rod 234 and the housing 231, and is used to generate a restoring force when the push rod 234 moves away from the limiting portion 2322.

[0059] The push rod 234 is a component that cooperates with the buckle 241, used to push the buckle 241 during the unlocking process, allowing the buckle 241 to be smoothly pulled out of the insertion port 2312. The shape and size of the push rod 234 can match the shape of the buckle 241 to ensure that the push rod 234 can effectively push the buckle 241. In this embodiment, the push rod 234 is a rectangular rod structure, the extension direction of the push rod 234 is perpendicular to the extension direction of the main body 2321, and it is slidably connected to the upper side of the main body 2321. The second elastic member 235 is an elastic member connected between the push rod 234 and the housing 231, used to generate a restoring force when the push rod 234 moves away from the limiting part 2322, so as to drive the push rod 234 to move towards the limiting part 2322. In this embodiment, the second elastic member 235 is a cylindrical helical spring, one end of the second elastic member 235 is connected to the push rod 234, and the other end is connected to the inner wall of the housing 231.

[0060] When the buckle body 241 is inserted into the locking chamber 2311 and engages with the limiting part 2322, the end of the buckle body 241 abuts against the side surface of the push rod 234 facing the limiting part 2322. After the buckle body 241 is fully inserted and the limiting part 2322 is engaged in the locking hole 2411, the push rod 234, under the action of the second elastic element 235, applies a pushing force to the buckle body 241 in the direction of the limiting part 2322, thereby pressing the buckle body 241 against the limiting part 2322 and improving the connection stability of the first buckle 230 and the second buckle 240. When the patient presses the unlocking part 2323 to disengage the limiting part 2322 from the locking groove, the push rod 234, under the action of the second elastic element 235, pushes the buckle body 241 toward the insertion port 2312, causing part of the buckle body 241 to automatically pop out, making the unlocking process smoother.

[0061] The first connecting strap 210 can be connected to the first buckle 230 in any way, such as by sewing, gluing, or snap-fit. In this embodiment, the first buckle 230 also includes a first adjusting buckle 236 disposed on the side of the housing 231 facing away from the insertion port 2312. The first adjusting buckle 236 has at least two parallel and spaced-apart first adjusting grooves 2361, and the first connecting strap 210 is wound around the two first adjusting grooves 2361.

[0062] The first adjusting buckle 236 can be made of materials such as plastic or metal, possessing sufficient strength and rigidity to support the tension of the first connecting strap 210 and maintain the stability of the adjusted state. The first adjusting buckle 236 can be integrally formed onto one side of the housing 231, or it can be connected to the housing 231 as an independent component. The shape and size of the first adjusting buckle 236 can be designed according to the width of the first connecting strap 210 and usage requirements to ensure that the first connecting strap 210 can slide smoothly within the first adjusting groove 2361. In this embodiment, the first adjusting buckle 236 has a rectangular structure, and the first adjusting groove 2361 has a rectangular groove structure. One end of the first connecting strap 210 is wound around the two first adjusting grooves 2361 of the first adjusting buckle 236, utilizing the friction between the surfaces of the first connecting strap 210 and the first adjusting buckle 236 to achieve connection and fixation. Furthermore, the winding position of the first connecting strap 210 within the two first adjustment slots 2361 can be adjusted to change the length of the first connecting strap 210 located between the first buckle 230 and the restraint garment body 100, thereby adapting to different patient body types and adjusting the restraint force on the patient's lower limbs.

[0063] Furthermore, the second connecting strap 220 can be connected to the second buckle 240 in any manner. In this embodiment, the second buckle 240 also includes a second adjusting buckle 242 disposed on one side of the buckle body 241. The second adjusting buckle 242 has at least two parallel and spaced-apart second adjusting grooves 2421, and the second connecting strap 220 is wound around the two second adjusting grooves 2421. The second adjusting buckle 242 and the buckle body 241 can be integrally formed, or it can be connected to the buckle body 241 as an independent component. The structure of the second adjusting buckle 242 can be the same as the structure of the first adjusting buckle 236, so as to change the length of the second connecting strap 220 located between the second buckle 240 and the restraint garment body 100, further improving the convenience of adjusting the length of the fixing strap 200.

[0064] In use, after the patient puts on the restraint garment body 100, they assume a left lateral decubitus position. Medical staff then wrap the first connecting strap 210 or the second connecting strap 220 around the patient's popliteal fossa, and connect the first buckle 230 and the second buckle 240. The chest fixation strap 200b is used in the same way as the shoulder fixation strap 200a. Through the combined action of the two sets of fixation straps 200, the patient is firmly fixed in a left lateral decubitus position, preventing postural retraction. This allows the patient's lower limbs to be flexed to their maximum extent, with both knees close to the chest and the shoulders close to the knees, widening the intervertebral space and facilitating lumbar puncture surgery. Furthermore, the procedure only requires wrapping the first connecting strap 210 or the second connecting strap 220 around the popliteal fossa, offering advantages of simple and convenient operation and high efficiency.

[0065] Reference Figure 1In some embodiments, the fixing strap 200 may further include a flexible pad disposed on the first connecting strap 210 or the second connecting strap 220, for padding the popliteal fossa when the first connecting strap 210 or the second connecting strap 220 passes around the popliteal fossa.

[0066] The flexible pad is made of soft materials such as sponge, memory foam, or latex to improve patient comfort and avoid pressure or discomfort in the popliteal fossa during prolonged periods of immobility. The shape and size of the flexible pad can be adapted to the contour of the popliteal fossa to ensure that when the first connecting strap 210 or the second connecting strap 220 passes around the popliteal fossa, the flexible pad can fully cover the popliteal fossa area, providing even support and cushioning.

[0067] Understandably, the flexible pad can be placed on either the first connecting band 210 or the second connecting band 220, specifically on the one that needs to contact the patient's popliteal fossa. For example, the flexible pad can be placed on the first connecting band 210, so that during operation, the first connecting band 210 passes around the patient's popliteal fossa while the flexible pad is placed in the popliteal fossa, improving the patient's comfort.

[0068] The following explanation will take the example of a flexible pad being installed on the first connecting strip 210 to further illustrate the concept of a flexible pad. Of course, the following explanation of the flexible pad also applies to its installation on the second connecting strip 220.

[0069] Reference Figure 8 In this embodiment, the flexible pad is a sponge sleeve 250, which is slidably fitted onto the first connecting band 210. The sponge sleeve 250 is made of a porous elastic material and can be circular, elliptical, or rectangular, adaptable to different shapes of connecting bands. The inner diameter of the sponge sleeve 250 is slightly larger than the outer diameter of the fixing band 200 to create a clearance fit, allowing the sponge sleeve 250 to slide on the first connecting band 210. Medical personnel can manually adjust the position of the sponge sleeve 250 according to the patient's body shape to accurately cover the bony prominence of the popliteal fossa. This reduces the pressure on the patient's popliteal fossa during prolonged fixation, improving patient comfort during lumbar puncture.

[0070] It is understood that the first connecting strap 210 and the second connecting strap 220 are respectively located on the left and right sides of the restraint garment body 100. When the patient wears the restraint garment body 100, the first connecting strap 210 and the second connecting strap 220 are located on the left and right sides of the patient, respectively. The length of the first connecting strap 210 can be set relatively long, so that after the patient is positioned, medical staff use the first connecting strap 210 to go around the patient's popliteal fossa and connect it to the second connecting strap 220 on the patient's right side. Alternatively, the length of the second connecting strap 220 can be set relatively long, so that after the patient is positioned, medical staff use the second connecting strap 220 to go around the patient's popliteal fossa and connect it to the first connecting strap 210 on the patient's left side. The flexible pad can be placed on either the first connecting strap 210 or the second connecting strap 220 depending on the actual usage.

[0071] Reference Figure 1 and Figure 2 In this embodiment, a flexible pad is disposed on the second connecting strap 220, and after the patient is fixed in a left lateral decubitus position, the first buckle 230 and the second buckle 240 are located on the patient's right side. When the patient is in a left lateral decubitus position, with their right side facing upwards, the first buckle 230 and the second buckle 240 are both located on the patient's right side, which facilitates the actual operation of the fixation strap 200 by medical staff. They can directly operate the connection of the first buckle 230 and the second buckle 240, adjust the length of the first connecting strap 210, and perform other operations, further improving the ease of operation.

[0072] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
