1. A biological signal detecting apparatus comprising:
a band pass filter (BPF) to which a biological signal is input via a lead directly connected to a subcutaneous tissue that emits the biological signal including a predetermined signal of a first frequency and which outputs a filtered biological signal by filtering a signal (biological event signal) of a predetermined frequency including the first frequency; and
a peak detecting means to which at least the filtered biological signal is input and which detects a peak location of the biological event signal by processing the filtered biological signal,
wherein the BPF includes a first order high-pass filter (HPF) which filters a frequency higher than a second frequency and a first order low-pass filter (LPF) which filters a frequency lower than a third frequency,
wherein the HPF and the LPF are connected in series between the lead and the peak detecting means, and
wherein a difference between the second frequency and the third frequency is less than or equal to 10 Hz.
2. The biological signal detecting apparatus according to claim 1,
wherein the second frequency is less than the first frequency and greater than or equal to 6 Hz, and
wherein the third frequency is greater than the first frequency and less than or equal to 25 Hz.
3. The biological signal detecting apparatus according to claim 1, further comprising:
a gain amplifier which is connected between the HPF and the LPF and amplifies a signal gain.
4. The biological signal detecting apparatus according to claim 3,
wherein the gain amplifier is a variable gain amplifier, and
wherein a gain of the variable gain amplifier is varied to an extent to which a signal component decayed by the BPF is compensated for.
5. The biological signal detecting apparatus according to claim 1, wherein both the HPF and the LPF are configured in a switched capacitor type.
6. An implantable medical device comprising:
the biological signal detecting apparatus according to claim
a diagnosis means; and
a therapy signal generating means,
wherein the biological signal is an IFCG signal,
wherein the tissue is a heart,
wherein the biological event signal is an R wave,
wherein the lead is connected to at least one of a right ventricle and a left ventricle of the heart,
wherein the diagnosis means receives an input of the peak location and outputs a diagnosis result corresponding to information of the peak location; and
wherein the therapy signal generating means receives an input of the diagnosis result and applies a therapy signal corresponding to the diagnosis result to an atrium for which therapy is necessary via the lead.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A carry bag comprising:
a compartment for receiving items;
a first panel attached to or formed integrally with the carry bag alongside the compartment;
a second substantially rectangular panel located externally of the compartment and supported by a hinge to pivot with respect to the first panel;
one or more straps attached at or near the periphery of the second panel and extending from a position remote from the hinge to a position proximal of the hinge for securing the carry bag against the torso of a user;
the carry bag being adaptable between a first configuration in which the first and second panels are mutually parallel, and a second configuration in which the first and second panels are mutually non-parallel and in which the first panel forms a support surface extending away from the user’s torso above the compartment, and wherein in both said configurations, the second panel can be retained substantially flat against the torso of a user by the straps.
2. The carry bag of claim 1, wherein said straps comprise a pair of shoulder straps extending from the second panel at an edge remote from the hinge.
3. The carry bag of claim 2, wherein said straps further comprise a waist strap extending from the second panel at an edge proximal to the hinge.
4. The carry bag of claim 1, further comprising an extension panel attached to the first panel and adapted to extend away from the first panel to provide an auxiliary surface area contiguous with said support surface.
5. The carry bag of claim 4, wherein the auxiliary panel slides with respect to the first panel and the first panel comprises slots and the auxiliary panel comprises pins which fit into said slots.
6. The carry bag of claim 1, further comprising a zipper extending partially about the periphery of the first and second panels and which when closed maintains the said first configuration of the carry bag.
7. The carry bag of claim 1, wherein the first panel is rigid and wherein the hinge is formed integrally with the first panel.
8. The carry bag of claim 7, wherein the second panel is rigid and wherein the hinge is also formed integrally with the second panel.
9. The carry bag of claim 7, wherein the hinge comprises attachment fingers adapted to be attached to the carry bag at the second panel.
10. The carry bag of claim 7, wherein the hinge comprises a U-channel adapted to be attached to the carry bag adjacent to the second panel.
11. The carry bag of claim 1, wherein the hinge comprises a pair of abutment flanges which abut one another to limit the maximum angle of pivotal movement between the first and second panels.
12. The carry bag of claim 11, wherein one of the abutment flanges comprises an array of apertures\u2014each selectively adapted to receive a buffer against which the other flange bears to thereby adjust said maximum angle.
