Description

Detailed Description of the Invention

Background 1. TECHNICAL FIELD The present disclosure relates generally to the field of vascular therapy for application to a body limb, and more particularly to a compression device having a removable portion.

2. 2. Description of Related Art Conditions that form blood clots such as deep vein thrombosis (DVT) and peripheral edema are serious problems for immobile patients and similar people. Such patients and people include patients undergoing surgery, patients with numbness, long-term bed care patients and others. These clot symptoms typically occur in the deep veins of the lower limbs and / or pelvis. These veins such as the iliac, femoral, popliteal and tibia circulate oxygen-depleted blood to the heart. When these venous blood circulations are suppressed due to disease, injury or inactivity, blood tends to accumulate or become congested. Static congestion is good for dangerous clot formation. The major risk associated with this condition is cardiovascular circulatory disturbance. The most serious is that the clot fragments peel off and move. Pulmonary embolism forms a main pulmonary artery occlusion and is life threatening.

  Symptoms and resulting risks associated with the patient's immobility can be suppressed or alleviated by applying intermittent pressure to the patient's limbs to assist in blood circulation. Well known devices such as one-piece pads and compression boots have been used to assist in blood circulation. See, for example, US Pat. Nos. 6,290,662 and 6,494,852.

  For example, sequential compression devices consisting of an air pump connected to a disposable wrap pad by a series of fluid conduits such as air tubes have been used. This wrapping pad is placed around the patient's leg. Next, the air is forcibly sent sequentially to different parts of the winding pad to create pressure around the calf and improve venous perfusion.

  These known devices have various disadvantages due to their bulkiness and cumbersome use. These disadvantages are disadvantageous in that they reduce comfort, adaptability, and hinder patient mobility during postoperative recovery.

  Therefore, it would be highly desirable to overcome the disadvantages and drawbacks of the prior art with a prophylactic sequential compression device that is not bulky, simple to use, and has improved patient comfort and conformability. It is desirable to include a removable portion on the prophylactic sequential compression device to achieve the benefits of the present disclosure. It would be further desirable if the prophylactic sequential compression device had a valve connector that facilitated quick removal from a pressurized fluid source. The preventive sequential compression device is intended to be simple and efficient to manufacture.

SUMMARY Accordingly, in order to overcome the disadvantages and drawbacks of the prior art, a compression device is provided that is not bulky and simple to use, improving patient comfort and conformability. Desirably, the compression device includes a removable portion to achieve the benefits of the present disclosure. Most desirably, the compression device has a valve connector that facilitates rapid removal from a pressurized fluid source. The compression device can be manufactured easily and efficiently.

  The compression device according to the principles of the present disclosure can be switched to a sleeve of knee length by tearing or otherwise removing the thigh bladder and disconnecting the thigh bladder from the air supply line. A thigh length compression sleeve is included. In one embodiment, the thigh bladder air supply line can be easily removed in conjunction with the thigh bladder and is attached at or near the site where the thigh bladder is removed from the sleeve. Thus, it is possible to remove both the thigh bladder and the thigh bladder supply line with one movement. The interchangeable sleeve allows the patient to use a more comfortable sleeve (knee versus thigh) since the risk of DVT is reduced post-operatively. This provides a variety of options for the therapist while using a single device.

  In another embodiment, the compression device is perforated to improve patient compliance and comfort while wearing the device over time. The device is intended to be used with both mobile and / or fixed compression systems. The source of pressurized fluid continues to deliver pressurized fluid after the valve is removed. The pressurized fluid source is notified with a loud warning sound when the tube is tangled and with a small warning sound when the tube is leaked. The compression device is activated sequentially by increasing the pressure through a tube corresponding to the three parts of the sleeve. The distal end is an ankle bladder (high pressure) and the proximal end is a thigh bladder (low pressure). The pressurized fluid source pumps air to the sleeve in a 60 second cycle of pressurizing for 11 seconds and reducing the remaining time.

  In one embodiment, a compression device according to the principles of the present disclosure includes a sleeve that is configured to be deployable about a limb. The sleeve includes a first portion that defines a first expansion chamber and a second portion that defines a second expansion chamber and a third expansion chamber. The second portion includes a connector in fluid communication with the pressurized fluid source, the first expansion chamber, the second expansion chamber, and the third expansion chamber, thereby facilitating fluid communication between the pressurized fluid source and each chamber. Become. The first part can be removed from the second part.

  The first part is connected to the second part via a perforated attachment. The first part is configured to be arranged around the first part of the limb, and the second part is configured to be arranged around the second part of the limb. A second expansion chamber may be disposed in the second part so as to be disposed around the second part of the limb, and a third expansion chamber is disposed in the second part so as to be disposed around the third part of the limb. May be.

  Alternatively, the compression device can include a variety of welds and bladders that create a quilting effect. For example, the first, second, and third expansion chambers can each define at least one subchamber.

  The sleeve may define at least one exhaust opening. The at least one opening can include an opening formed in the surface of the expansion chamber. The at least one opening may include a slit disposed between the second expansion chamber and the third expansion chamber.

  The connector can communicate with the chamber via a tube passage. The tube passage of the first expansion chamber can be removed from the connector. Pressurized fluid can be delivered to the chamber in such a way as to expand the chamber at sequential time intervals, so that, for example, the first expansion chamber expands, followed by (after 2.5 seconds) the second expansion chamber, (3 After 3 seconds, the third expansion chamber expands to a total of 11 seconds from the start of the first expansion chamber. The entire chamber is then evacuated to atmospheric pressure at the same time.

  In an alternative embodiment, the compression device includes a sleeve configured to wrap around the leg and defining a plurality of exhaust openings. The sleeve includes a thigh portion that defines a first expansion chamber having a subchamber. The sleeve further includes a calf portion defining a second expansion chamber having a sub-chamber and an ankle portion defining a third expansion chamber having a sub-chamber. The ankle portion includes a valve connector that fluidly communicates both the pressurized fluid source and the chamber through the tube passage to facilitate expansion of the chamber. The thigh portion is removably connected to the calf portion via a perforated attachment, and the tube passage of the first expansion chamber is removable from the valve connector.

  In an alternative embodiment, the compression device includes an expandable sleeve configured to be placed around the leg. The sleeve extends from the lower leg to the upper knee. The sleeve can be switched from a length extending from below the knee to above the knee to a length extending only below the knee. The length of the sleeve extending from below the knee to above the knee can include a first portion that can be disposed about the thigh of the leg, and the first portion can be removed from the sleeve. The first part is connected to the sleeve via the perforated part.

  In one method, the ankle bladder is squeezed for 2.5 seconds, the central bladder is squeezed for 2.5 seconds, and the proximal bladder is also squeezed for 2.5 seconds. After 11 seconds, all bladders are evacuated simultaneously. By pulling the thigh apart, the entire leg can be switched to the knee length. An exhaust slit is placed on the back of the calf. This dissipates heat, reduces itchiness and adapts movement. A knit or knitted fabric may be used under the compression sleeve.

  In an alternative embodiment, a method for performing compression on a limb of a body is the step of providing a sleeve configured to be deployable about the limb, the sleeve comprising a first portion defining a first expansion chamber. And a second portion defining a second expansion chamber and a third expansion portion, the second portion including a pressurized fluid source and a connector in fluid communication with each chamber, whereby the pressurized fluid source and each chamber Fluid communication between the first part and the second part can be removed; step; placing a sleeve around the limb; delivering pressurized fluid to the first expansion chamber; Delivering fluid to the second expansion chamber; delivering pressurized fluid to the third expansion chamber; contracting the chamber; and removing the first portion from the second portion Step; including.

  Each of the delivering steps may be performed for 2.5 seconds. The removing step includes disconnecting the first expansion chamber from the connector. The removing step can include tearing the first portion from the second portion via a perforated attachment.

  In an alternative embodiment, a method of performing compression on a body limb provides an expandable sleeve configured to be positionable around a leg; the sleeve is at a length from below the knee to above the knee. Placing the sleeve around the limb to expand; delivering pressurized fluid to the sleeve; contracting the sleeve; and extending the length from below the knee to above the knee to a length extending only below the knee Switching between. The step of placing the sleeve around the extremities so that the sleeve extends from below the knee to above the knee can include a first portion of the sleeve placed around the leg thigh. The switching step can include tearing the first portion from the sleeve.

Detailed Description of Exemplary Embodiments Exemplary embodiments of the disclosed compression device and method of operation are described in terms of vascular treatment including a prophylactic compression device for application to the extremities of the body and are removable parts. This will be described in more detail in terms of a compression treatment device having The compression device is intended to be used to prevent and overcome the risks associated with patient immobility. Furthermore, it is also intended that the compression device relieves the medical condition resulting from the patient's immobility and prevents, for example, DVT, peripheral edema and the like. The compression device according to the present disclosure is intended to be attributed to any type of venous compression system, including but not limited to prophylactic sequential compression devices. The term “prophylactic sequential” should not be construed as limiting the general venous compression treatment system described herein. However, it is envisaged that the present disclosure covers a wide range of immobilization of, for example, patients undergoing surgery, patients with numbness, long-term bed therapy, obese patients, elderly patients, malignant tumor patients, thromboembolic patients, and the like. I am considering applying the condition to a medical condition.

  In the following description, the term “proximal” refers to the portion of the structure that is closer to the subject's torso and the term “distal” refers to the portion of the structure that is further away from the torso. As used herein, the term “subject” refers to a patient who receives vascular treatment using a compression device. According to the present disclosure, the term “therapist” refers to an individual handling a prophylactic sequential compression device and may include support personnel.

  The following description includes a description of the compression device, followed by a description of an exemplary method of operating the compression device according to the principles of the present disclosure. Reference will now be made in detail to the exemplary embodiments and disclosure, which are illustrated in the accompanying figures.

  In the figures, like elements are designated by like numerals throughout the several views. Reference is first made to FIGS. 1 and 2 illustrating a prophylactic sequential compression device 10 constructed in accordance with the principles of the present disclosure. The compression device 10 includes, for example, a sleeve 12 configured to be arranged around the extremities, such as a leg L (FIGS. 4 to 6) of the subject's body. It is contemplated that the sleeve 12 and other portions of the compression device 10 may be placed, wrapped and attached to various limbs, limbs, etc. of the subject's body, for example legs, arms. The

  The sleeve 12 includes a first portion, such as a thigh portion 14. The first portion defines a first expansion chamber, such as the first expansion chamber 16. The second portion 18 of the sleeve 12 defines a second expansion chamber, such as the second expansion chamber 20, and a third expansion chamber, such as the third expansion chamber 22, for example. The first portion 14 and the second portion 18 can include one or more expansion chambers. It is further envisioned that the sleeve 12 or portions thereof may be disposable.

  The second portion 18 has a calf portion 24 that includes a second expansion chamber 20 and an ankle portion 26 that includes a third expansion chamber 22. It is contemplated that the first and second portions 18 may be placed on various portions of the subject's limb according to the requirements of a particular vascular treatment application. As will be described below, the ankle portion 26 is in fluid communication with a pressurized fluid source 30 via a valve connector 28 and a tube 62 (FIGS. 4C and 4D), and chambers 16, 20 via fluid passages including tubes. , 22 also includes a valve connector 64 in fluid communication (eg, US patent application Ser. No. 10 / 784,639, filed Feb. 23, 2004, incorporated herein by reference in its entirety). (Refer to the valve connector in the name "fluid conduit connector device".) Tube 62 is made up of three separate tubes or lumens 65A, 65B, 65C. This configuration facilitates fluid communication between the pressurized fluid 30 and the chambers 16, 20, 22.

  The thigh portion 14 is removable from the second portion 18. For example, the calf portion 24 is removably connected to the thigh portion 14 via a perforated attachment 32. This removable configuration has the advantage of reducing the bulkiness of the compression device 10 by a simple operation and increasing the comfort and adaptability to the subject. The compression device 10 also provides sufficient mobility for the subject. It is contemplated that the sleeve 12 may include a flexible area, such as an elastic material or spandex material, that facilitates movement of the limb during use, disposed between the portions.

  As best seen in FIGS. 1 and 2, the sleeve 12 includes an upper sheet 34 and a lower sheet 36 that overlap to form the sleeve. The upper sheet 34 and the lower sheet 36 are joined and fixed at seams that define the expansion chambers 16, 20, 22. Seam portion 38 defines chamber 16, seam portion 40 defines chamber 20, and seam portion 42 defines chamber 22. The edge portion 44 extends around the sleeve 12 beyond the seam portions 38, 40, 42. It is intended that the sleeve 12 includes a plurality of seams that join the upper sheet 34 and the lower sheet 36 that are variously disposed around the sleeve 12. It is also intended that the seam portion may be processed by welding, stitching, formation by adhesion, heat sealing, or the like.

  The upper sheet 34 and lower sheet 36 may be a chamber 16 such as a film, fabric, etc., such as PVC (polyvinyl chloride) and PE (polyethylene), depending on the particular vascular treatment application and / or preference. , 20, 22 made of a material suitable for expansion. Semi-flexible and flexible fabrics such as urethane and silicone may be used. The sleeve 12 includes chambers 16, 20, 22 and can include a separation structure disposed with or attached to the sheets 34, 36. However, it will be appreciated by those skilled in the art that other materials and methods suitable for assembly and manufacture according to the present disclosure may be used.

  The sleeve 12 defines an exhaust opening, such as a sleeve hole 46, which provides a cooling action in a portion adjacent to the subject's limb. The sleeve hole 46 completely penetrates the upper sheet 34 and the lower sheet 36. This improves the comfort of the subject during use. The sleeve 12 includes a welded portion 48 that surrounds the sleeve holes 46 and seals the respective chambers away from the holes to prevent fluid communication therebetween. The sleeve 12 also includes an exhaust hole 47 that provides a cooling action. It is envisioned that the sleeve 12 may include a plurality of exhaust openings that are variously disposed around its periphery.

  For example, an exhaust opening such as an exhaust slit 50 is disposed between the expansion chamber 20 and the expansion chamber 22. The exhaust slit 50 completely penetrates the upper sheet 34 and the lower sheet 36. The exhaust slit provides a cooling effect to the subject and has the advantage of increasing calf and ankle mobility during use. It is contemplated that the exhaust slit 50 may be of various lengths.

  The thigh portion 14 includes an axial line of a spot weld 52 that defines a subchamber 54 of the expansion chamber 16. Similarly, the calf portion 24 includes the axial line of the spot weld 54 that defines the subchamber 56 of the expansion chamber 20, and the ankle portion 26 the spot weld 58 that defines the subchamber 60 of the expansion chamber 22. including. Assuming that the sub-chamber may alternatively be formed by continuous welding, bonding, hot sealing, and the like. It is further envisaged that the welds 58 may be arranged in various orientations to create alternative sub-chamber configurations.

  The valve connector 28 communicates with the chambers 16, 20, 22 via fluid passages. The fluid passage includes a tube 62 that connects the valve connector 28 to a pressurized fluid source 30, which may include a pump (eg, February 23, 2004, incorporated herein by reference in its entirety). (See the controller pump described in US patent application Ser. No. 10 / 784,323, filed Japanese Patent Application, entitled “Pressure Treatment System”). The pressurized fluid source 30 may be fixed or portable. Pressurized fluid source 30 may include the necessary electronic circuitry, computer software, etc., to perform blood treatment according to the principles of the present disclosure.

  The tube 62 is attached to the valve connector 28 via a coupler 64 as shown in FIG. A tube 66 extends from the valve connector 28 and fluidly connects to the expansion chamber 20. A tube 67 extends from the valve connector 28 and fluidly connects to the expansion chamber 22. A tube 68 extends from the valve connector 28 and fluidly connects to the expansion chamber 16. Tube 68 includes a quick removal port 70. The port 70 is attached to the valve connector 28 and is easily removed to facilitate removal of the thigh portion 14 from the calf portion 24. Tube 62 and lumens 65A, 65B, and 65C correspond to tubes 67, 66, and 68, respectively. It is assumed that the valve connector 28 can be fixed to the sleeve 12 by a detachable tether or the like. It is further envisioned that the port 70 can be secured to the valve connector 28 and the tube 68 can be removed from the thigh portion 14.

  The sleeve 12 includes a fastening component such as a hook loop pad 72 attached in a direction to be engaged with a corresponding hook loop pad (magic tape (registered trademark)) 74. The hook loop pads 72 and 74 can ensure the attachment of the sleeve 12 to the leg L of the subject. It is contemplated that one or more clamping parts can be variously arranged around the sleeve 12. Further, it is contemplated that the clamping component may include, for example, a clip, an adhesive, a pin, and the like.

  Reference is made to FIGS. A compression device 10 similar to that described above is assembled, disinfected and packaged for use. In use, the compression device 10 is prepared and operated so as to be arranged around the leg L of the subject. Tube 66 is connected to calf portion 24 and tube 67 is connected to ankle portion 26. Tube 68 connects to thigh portion 14. Tubes 66, 67, 68 are connected to valve connector 28. Valve connector 28 is connected to tube 62 and pressurized fluid source 30 (FIGS. 4C and 4D). Accordingly, the fluid passage of the compression device 10 achieves fluid communication between the pressurized fluid source 30 and the chambers 16, 20, 22.

  As shown in FIGS. 4A and 4B, the sleeve 12 wraps around the leg L and is fixed thereto via hook loop pads 72 and 74. The sleeve 12 extends from the lower part of the leg L through the second part 18 to the upper part of the knee through the thigh part 14. The compression device 10 operates sequentially by delivering pressurized fluid to the chambers 16, 20, 22 via fluid passages. In one embodiment, as shown in FIG. 7, the pressurized fluid source 30 delivers air to the sleeve 12 in a 60 second cycle that includes 11 seconds of pressurization and 49 seconds of depressurization. Deliver pressurized air to the expansion chamber 22 for 2.5 seconds. The pressurized air is then delivered to the expansion chamber 20 for 2.5 seconds. The pressurized air is then delivered to the expansion chamber 16 for 2.5 seconds. The compression device 10 is kept inflated for up to 11 seconds, and then the chambers 16, 20, and 22 are deflated simultaneously. It is contemplated that this sequential pressurization can be continued for multiple cycles according to the requirements of the particular vascular treatment application. Other sequential pressurization cycles are also contemplated. For example, it is envisaged that various forms of fluid, such as liquid or gas, can be delivered to the sleeve 12.

  The thigh portion 14 may be removed from the second portion 18 after a desired time of sequential pressurization has elapsed, such as a recovery time according to the requirements of a particular vascular treatment application. Therefore, the sleeve 12 can be switched from a length extending from below the knee to above the knee to a length extending only below the knee. The sleeve 12 is manipulated to tear and remove the thigh portion 14 from the calf portion 24 through the perforated portion 32 as shown in FIGS. 6A and 6B. The port 70 connected to the tube 68 can be quickly removed from the valve connector 28 with an easy operation, as shown in FIG. 5B. The remaining portion of the sleeve 12, including the calf portion 24 and the ankle portion 26, continues the operation described above alone. This allows the sleeve 12 to be switched from a device with full leg length to a device with knee length. The compression device 10 can be utilized to complete a desired vascular treatment application. Other uses are also contemplated, such as leaving the thigh portion 14 in the sleeve 12 without removal.

  As described above, in removing the thigh portion 14 arbitrarily, the user or therapist disconnects the tube material 68 and disconnects the port 70 from the connector 28. Connector 28 (and optionally disconnected port 70) ensures that a desired flow rate of fluid from fluid source 30 is achieved through connector 28 even when tube 68 is disconnected from connector 28. Composed. Such a continuous flow is preferred to maintain continuity with the pressurized fluid source 30.
