Description

Compressor {COMPRESSION APPARATUS}

The present invention relates generally to the field of vascular therapy for application to the limbs of the body, and more particularly to a compression device having removable parts.

A major concern of immobilized patients and people is the medical condition that constitutes clots in the blood, such as deep vein thrombosis (DVT) and peripheral edema. Such patients include people who experience surgery, anesthesia, or longer bedtime. This blood clumping condition usually occurs in the lower veins and / or the cardiac veins of the pelvis. Veins such as the long bones, thighs, glands and tibias return to the heart with free oxygen removed. For example, when blood circulation in such veins is delayed due to illness, injury or lethargy, blood tends to accumulate. The static buildup of blood is ideal for clumping up blood and forming masses. The main risk associated with this condition is that it interferes with cardiovascular circulation. Most seriously, blood clots can escape and move. Pulmonary embolites can be configured to block the main pulmonary artery, which is life threatening.

The condition and the resulting risk due to the patient's inability to move can be controlled or mitigated by applying intermittent pressure to the limbs of the patient, such as the legs, to aid in blood circulation. Known devices such as single piece pads and compression boots have been used to aid blood circulation. (See, eg, US Pat. Nos. 6,290,662 and 6,494,852)

For example, sequential compression devices have been used that consist of an air pump connected to a disposable body pad by a series air tube. Body pads are placed around the patient's leg. The air is then pushed inwards into the other parts of the body pad, thereby creating pressure around the calf and improving vein regression.

Such known devices may suffer from various drawbacks due to the volume of the devices and the cumbersomeness to use. These defects reduce comfort, flexibility, and adversely interfere with the patient's activity as the postoperative recovery progresses.

Therefore, it is desirable to improve the comfort and flexibility for the patient by reducing the volume and overcoming the disadvantages and drawbacks of the prior art with a preventive sequential compression device that is not cumbersome in use. In order to achieve the advantages of the invention it would be advantageous if the preventive sequential compression device comprises removable parts. It would be highly desirable if the preventive sequential compression device have a valve connector to facilitate rapid release from the pressurized fluid source. It is contemplated that the prophylactic sequential compression device is easily and efficiently manufactured.

This provides a compression device that reduces volume and does not bother during use, thereby enhancing patient comfort and flexibility and overcoming the drawbacks and drawbacks of the prior art. Preferably the compression device comprises a removable portion to achieve the advantages of the present invention. Most preferably the compression device has a valve connector that simplifies quick release from the pressurized fluid source. The compression device is manufactured easily and efficiently.

In accordance with the principles of the present invention, the compression device comprises a thigh length compression sleeve that turns away to a knee length sleeve by stripping away or removing the thigh bladder and disconnecting the femoral bladder air supply line. In one embodiment the femoral bladder air supply line will be easily removed with the femoral bladder and attach at or near the point where the femoral bladder is removed from the sleeve. This will allow removal of both the femoral bladder and the femoral bladder feed line in a single motion. The risk for DVT is reduced after surgery, so the switchable sleeve allows the patient to use a more comfortable sleeve. This gives the practitioner various options while using a single device.

In another embodiment, the compression device is perforated to provide improved flexibility and comfort to the patient for the entire length of time for wearing the device. It is contemplated that the device may be used with a portable and / or stationary compression system. The pressurized fluid source continues to deliver pressurized fluid after removing the valve. The pressurized fluid source can signal a high warning if there is a twist in the pipe, or a low warning if there is a leak in the pipe. The compression device is activated sequentially by increasing the pressure through the tube, in harmony with the three parts of the sleeve. The distal end is the ankle bladder and the (high pressure) tip is the femoral bladder (low pressure). The pressurized fluid source pushes air into the sleeve every 60 seconds, compressing for 11 seconds, and depressurizing the rest.

In one embodiment, according to the winry of the present invention, the compression device comprises a sleeve configured to be disposed about the limb. The sleeve includes a first portion defining a first expandable chamber and a second portion defining a second expandable chamber and a third expandable chamber.

The sleeve may define at least one vent hole. The at least one hole may comprise holes formed in the surface of the expandable chamber. The at least one aperture may comprise a slit disposed between the second expandable chamber and the third expandable chamber.

The connector may be in communication with the chamber via a tubular path. The tubular path of the first expandable chamber may be removable from the connector. The pressurized fluid can be delivered to the chamber for expansion of the pressurized fluid at sequential time intervals, such as for example the first expandable chamber is expanded and then (2.5 seconds later) the second expandable chamber is expanded. The third expandable chamber is then expanded (after three seconds) and thus takes a total of 11 seconds from the start of the first expandable chamber. The chambers are then all vented to the atmosphere at the same time.

In an alternative embodiment the compression device comprises a sleeve configured to wrap around the leg and define a plurality of vent holes. The sleeve includes a thigh that defines a first inflatable chamber having a subchamber. The sleeve further comprises a calf portion defining a second inflatable chamber having a subchamber and an ankle defining a third inflatable chamber having a subchamber. The ankle includes a valve connector that promotes swelling of the chambers by fluidly communicating both the pressurized fluid source and the chamber through a tubular path.

As used herein, the term "subject" refers to a patient who is undergoing vascular treatment using a compression device. According to the present invention, the term "owner" refers to an individual who manages the compression device and may include a guardian.

The description below includes a description of a compression device and then describes an exemplary method of operating the compression device in accordance with the principles of the present invention. Reference will now be made in detail to the exemplary embodiments and disclosures described in conjunction with the accompanying drawings.

Reference is made to the drawings wherein like parts are designated by like reference numerals throughout the several views. Referring first to Figures 1 and 2, there is shown a preventive sequential compression device 10 constructed in accordance with the principles of the present invention. The compression device 10 comprises a sleeve 12 that is configured to be arranged around a limb, such as, for example, the leg L of the subject body (FIGS. 4-6). It is contemplated that the sleeve 12 and other portions of the compression device 10 may be disposed, wrapped, and mounted with various limbs, ends, etc. of the subject body, such as, for example, legs, arms, and the like.

Sleeve 12 includes a first portion, such as, for example, thigh 14, that defines a first expandable chamber, such as, for example, first inflatable chamber 16. The second portion 18 of the sleeve 12 defines, for example, a second expandable chamber such as the second inflatable chamber 20 and a third expandable chamber such as the third inflatable chamber 22. . It is intended that the first portion 14 and the second portion 18 can include one or a plurality of expandable chambers. In addition, the sleeve 12 or portions thereof are intended to be disposable.

The second portion 18 has a cap 24 including a second inflatable chamber 20 and an ankle 26 including a third inflatable chamber 22. It is contemplated that the first portion and second portion 18 may be placed around various portions of the subject limb, depending on the requirements of the particular vascular treatment application. Ankle 26 is connected to valve connector 64 (FIGS. 4C and 4D) and tubing in fluid communication with pressurized fluid source 30 through valve connector 28 and tubing 62 as discussed below. Chambers 16, 20, 22 via a fluid path comprising. (See, for example, the valve connector described in US patent application Ser. No. 10 / 784,639, filed Feb. 23, 2004, entitled “Fluid Conduit Connector Device,” the entire contents of which are described herein by reference). Consists of three removed tubes or lumens 65A, 65B, 65C. This configuration promotes fluid communication between the pressurized fluid 30 and the chambers 16, 20, 22.

The thigh 14 is removable from the second portion 18. For example, the cap 24 is detachably connected to the thigh 14 via the perforations 32 as discussed. This removable configuration advantageously reduces the volume of the compression device 10 through easy manipulation in order to increase comfort and flexibility to the object. Compression apparatus 10 also provides increased mobility to the subject. The sleeve 12 is intended to include a flexible portion, such as elastic or spandex materials, disposed between the portions to facilitate limb mobility during use.

As best shown in FIGS. 1 and 2, the sleeve 12 includes an upper sheet 34 and a lower sheet 36 that are overlaid to form the sleeve. The upper sheet 34 and the lower sheet 36 are fixedly coupled to the seams defining the inflatable chambers 16, 20, 22. The joint 38 defines a chamber 16, the joint 40 defines a chamber 20, and the joint defines a chamber 22. The edge 44 extends beyond the seams 38, 40, 42 around the sleeve 12. The sleeve 12 is believed to comprise a plurality of seams that join the top sheet 34 and the bottom sheet 36 and are variously disposed around the sleeve. The joints can also be welded, sealed or formed by adhesives, thermal seals or the like.

The top sheet 34 and the bottom sheet 36 are chambers 16, 20, 22, such as films and fabrics, such as, for example, PVC (polyvinyl chloride) and PE (polyethylene), depending on the particular vascular treatment application and / or preference. It is made from a material suitable for swelling. Semi-flexible and flexible fabrics such as urethanes and silicones can also be used. Sleeve 12 may include a removed structure that includes chambers 16, 20, 22 and is disposed with or mounted to sheets 34, 36. However, those skilled in the art will recognize that other materials and methods of assembly suitable for assembly and manufacture in accordance with the present invention will also be appropriate.

The sleeve 12 defines a vent, such as a sleeve opening 46, for cooling an adjacent portion of the limb of the subject. Sleeve opening 46 penetrates completely through top sheet 34 and bottom sheet 36. This advantageously improves comfort for the subject during use. The sleeve 12 includes a weld 48 surrounding the sleeve opening 46 to seal each chamber from the opening and prevent fluid communication therebetween. Sleeve 12 also includes vent holes 47 to provide cooling. The sleeve 12 is intended to include a plurality of vent holes that are variously arranged around it.

For example, a vent opening, such as vent slit 50, is disposed between the inflatable chamber 20 and the inflatable chamber 22. The vent slit 50 completely passes through the upper sheet 34 and the lower sheet 36. Aeration slit advantageously provides cooling to the subject and increases the mobility of the cap and ankle during use. The vent slit 50 may extend to various lengths.

The thigh 14 includes an axial line of a spot weld 52 that defines the subchamber 54 of the inflatable chamber 16. The cap 24 includes an axial line of the spot weld 55 that defines the subchamber 56 of the inflatable chamber 20, and the ankle 26 includes a subchamber of the inflatable chamber 22. A spot weld 58 defining 60. Alternatively, the subchambers 54, 56, 60 may be formed through continuous welding, adhesives, hot sealing, or the like. Spot welds 58 may also be placed in various orientations to create an alternative configuration for the subchamber.

The valve connector 28 communicates with the chambers 16, 20, 22 through a fluid path. The fluid path includes tubing 62 that connects valve connector 28 to a pressurized fluid source 30, which may include a pump. (See, e.g., the controller pump described in US patent application Ser. No. 10 / 784,323, filed Feb. 23, 2004 under the name "compression processing system," the entirety of which is described herein by reference.) Pressurized fluid source 30 Can be fixed or portable. It is contemplated that the pressurized fluid source 30 may include electronics, computer software, and the like necessary to perform vascular treatment in accordance with the principles of the present invention.

Pipe 62 is attached to valve connector 28 via coupler 64 as shown in FIG. Tubing 66 (second tubing) extends from valve connector 28 and fluidly connects to inflatable chamber 20. Tubing 67 (third tubing) extends from valve connector 28 and fluidly connects to inflatable chamber 22. Tubing 68 (first tubing) extends from valve connector 28 and fluidly connects to inflatable chamber 16. Tubing 68 includes a quick disconnect port 70. The port 70 attaches with the valve connector 28 and is easily removable, thus facilitating the removal of the thigh 14 from the cap 24. Pipe 62 and lumens 65A, 65B, 65C correspond to pipes 67, 66, 68, respectively. The valve connector 28 is intended to be secured, removable and constrained with the sleeve 12. Port 70 may also be secured with valve connector 28 and piping 68 may be removable from thigh 14.

The sleeve 12 includes, for example, a fixing portion, such as a hook and loop pad 72, which is mounted in an orientation for engagement of the corresponding hook and loop pad 74. The hook and loop pads 72, 74 allow for secure mounting of the sleeve 12 and the leg L of the subject. It is contemplated that one or a plurality of fastening portions may be variously disposed around the sleeve 12. It is contemplated that the fastening portions may also include, for example, clips, adhesives, pins, and the like.

4-7, a compression device 10 similar to that described above is assembled, sterilized and packaged for use. In operation the compression device 10 is provided and manipulated to be placed around the object leg L. FIG. Pipe 66 is connected to the cap 24 and the pipe 67 is connected to the ankle (26). Pipe 68 is connected to the thigh 14. Tubing 66, 67, 68 is connected to valve connector 28 that is connected to tubing 62 and pressurized fluid source 30 (FIGS. 4C and 4D). Accordingly, the fluid path of the compression device 10 constitutes fluid communication between the pressurized fluid source 30 and the chambers 16, 20, 22.

The sleeve 12 is wrapped around the leg L as discussed above as shown in FIGS. 4A and 4B and secured against it through the hook and loop pads 72, 74. The sleeve 12 extends through the second portion 18 from below the knee of the leg L and through the thigh 14 onto the knee. The compression device 10 is sequentially activated by delivering pressurized fluid to the chambers 16, 20, 22 through a fluid path. As shown in FIG. 7 and FIG. 7, the pressurized fluid source 30 delivers air to the sleeve 12 in a 60 second period, including 11 seconds for compression and 49 seconds for reduced pressure. Compressed air is delivered to the inflatable chamber 22 for 2.5 seconds. Thereafter, compressed air is delivered to the inflatable chamber 20 for 2.5 seconds. Thereafter, compressed air is delivered to the inflatable chamber 16 for 2.5 seconds. The compression device 10 remains inflated for a few seconds until 11 seconds, after which the chambers 16, 20, 22 are simultaneously retracted. It is contemplated that this sequential compression may continue for multiple cycles depending on the requirements of the particular vascular treatment application. Other sequential compression periods are also contemplated. Various forms of fluids are intended to be delivered to the sleeve 12, such as, for example, liquid, gas, and the like.

After a predetermined sequential compression time, such as recovery time according to the requirements of a particular vascular treatment application, the thigh 14 may be removed from the second portion 18. Accordingly, the sleeve 12 is switchable from the length extending below the knee to the length of the knee to the length extending only below the knee. Sleeve 12 is manipulated such that thigh 14 is removed through perforation 32 and peeled from cap 24 as shown in FIGS. 6A and 6B. Port 70 connected with tubing 68 is easily manipulated to quickly disconnect from valve connector 28 as shown in FIG. 5B. Only the remainder of the second portion 18, including the sleeve 12, the cap 24 and the ankle 26, remains and continues to operate as described above. This converts the sleeve 12 from the complete knee length device to the knee length device. Compression device 10 may be used to complete certain vascular treatment applications. Other methods of use are also contemplated. For example, it is contemplated that thigh 14 may not be removed, or may be left with sleeve 12.

As described above, upon selective removal of the thigh 14, a user or skilled person disconnects the tubing member 68 and disconnection port 70 from the connector 28. Connector 28 (and optionally disconnect port 70) is such that a predetermined amount of fluid flow from fluid source 30 continues through connector 28 when removing tube 68 from connector 28.
