Abstract
Abstract A device for circulating treating fluid through the nasal fossae includes a pump which has a suction inlet and a pressure outlet. A pair of elongated tubular structures respectively communicate with the suction inlet and pressure outlet, and these tubular structures have distant from the pump end portions respectively adapted to be placed in communication with the nasal fossae. A suitable treating fluid is adapted to be situated in one of the tubular structures so that when the pump is operated the treating fluid will be circulated from the pressure outlet of the pump through the tubular structure connected thereto into one of the nasal fossa and returned through the other nasal fossa into the other tubular structure to be sucked through the latter back to the suction inlet of the pump so that in this way a suitable treating fluid can be circulated through the nasal fossae.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
186 words
In a device for circulating a treating fluid through the nasal fossae, pump means having separate from each other a suction inlet and pressure outlet, suction tubular means communicating with said suction inlet and pressure tubular means communicating with said pressure outlet, said pump means cooperating with said suction and pressure tubular means for creating suction in said suction tubular means and pressure in said pressure tubular means, said suction and pressure tubular means respectively having distant from said pump means end portions which respectively carry a pair of means for placing said end portions respectively in communication with the nasal fossae, so that when a treating fluid is situated in one of said tubular means, said pump mean may be operated for circulating in a closed circuit in only one direction the treating fluid through the nasal fossae with the treating fluid entering under pressure from said pressure tubular means into one nasal fossa and being withdrawn through the other nasal fossa while entering from the latter into the suction tubular means to again be delivered by said pump means to said pressure tubular means.
Claim 2
Dependent Claim
186 words
In a device for circulating a treating fluid through the nasal fossae, pump means having separate from each other a suction inlet and pressure outlet, suction tubular means communicating with said suction inlet and pressure tubular means communicating with said pressure outlet, said pump means cooperating with said suction and pressure tubular means for creating suction in said suction tubular means and pressure in said pressure tubular means, said suction and pressure tubular means respectively having distant from said pump means end portions which respectively carry a pair of means for placing said end portions respectively in communication with the nasal fossae, so that when a treating fluid is situated in one of said tubular means, said pump mean may be operated for circulating in a closed circuit in only one direction the treating fluid through the nasal fossae with the treating fluid entering under pressure from said pressure tubular means into one nasal fossa and being withdrawn through the other nasal fossa while entering from the latter into the suction tubular means to again be delivered by said pump means to said pressure tubular means.
Claim 3
Dependent Claim
25 words
The combination of claim 1 and wherein said pressure tubular means carries a pressure-limiting means for limiting the pressure created in said pressure tubular means.
Claim 4
Dependent Claim
31 words
The combination of claim 1 and wherein said suction tubular means includes as a part thereof a container means for containing a treating fluid to be circulated through the nasal fossae.
Claim 5
Dependent Claim
37 words
The combination of claim 3 and wherein a filter means is situated in said suction tubular means between said container means and said suction inlet of said pump means for filtering fluid withdrawn from said container means.
Claim 6
Dependent Claim
70 words
The combination of claim 2 and wherein said pressure-limiting means forms part of said pressure tubular means and includes a portion of said pressure tubular means which is made of an elastic, deformable wall which responds to pressure greater than a given limiting pressure for expanding and increasing the volume of said pressure tubular means at the location of said pressure limiting means for preventing an excessive increase in pressure.
Claim 7
Dependent Claim
15 words
The combination of claim 1 and wherein said pump means is a motor-driven pump means.
Claim 8
Dependent Claim
16 words
The combination of claim 1 and wherein said pump means is a manually operable pump means.
Claim 9
Dependent Claim
81 words
The combination of claim 7 and wherein said manually operable pump means includes an elastic bulb adapted to be manually compressed and a pair of one-way valve means respectively situated at said suction inlet and pressure outlet for providing for flow of fluid only from said suction tubular means into said elastic bulb during expansion of the latter and for flow of fluid only out of said elastic bulb into said pressure tubular means during manual compression of said elastic bulb.
Claim 10
Dependent Claim
57 words
The combination of claim 1 and wherein each means at each end portion of each tubular means for placing the latter in communication with a nasal fossa includes a cannula carrying at its exterior an elastic flexible sealing flange surrounding each cannula for placing the latter in communication with a nasal fossa in a substantially fluid-tight manner.
Claim 11
Dependent Claim
39 words
The combination of claim 4 and wherein said pressure tubular means has an elastic deformable wall portion adapted to expand in response to excessive pressure for limiting the extent to which pressure can build in said pressure tubular means.
