Abstract

An interventional operation isolation transfer cabin includes a cabin body, and a lead wire access device and a wire in/out device which two are mounted on the cabin body, the cabin body is provided with a negative pressure generating device at one end and an air inlet at the other end, the negative pressure generating device is provided with an exhaust filter device at its air outlet, and an intake filter device is provided at the air inlet. Several operating openings are provided on side walls of the cabin body, each of the operating openings is in seal connection with an operating glove, and a glove opening of at least one operating glove faces an interior of the cabin body. Equipment wires required by an interventional operation are preset through the lead wire access device, and wires added midway under a sealing condition is guaranteed through the wire in/out device.

First claim

What is claimed is:

1 . An isolation transfer cabin for interventional operation, comprising:
a cabin body, which is provided with a negative pressure generating device at a first end and an air inlet at a second end;
wherein the negative pressure generating device is provided with an exhaust filter device at an air outlet of the negative pressure generating device;
wherein the air inlet comprises an intake filter device;
wherein a plurality of operating openings are provided on side walls of the cabin body;
wherein each of the operating openings is connected with an operating glove in a sealed manner, and a glove opening of at least one operating glove faces an interior of the cabin body;
wherein the cabin body comprises a bilge, a hatch, a left bulkhead, and a right bulkhead;
wherein the left bulkhead and the right bulkhead are connected to a left end and a right end of the bilge in a sealed and fixed manner, respectively;
wherein left end and right end of the hatch are connected to the left bulkhead and the right bulkhead, through airtight zippers, respectively;
wherein a rear side of the hatch is hinged with a rear side of the bilge; and
wherein a front side of the hatch can be opened or closed relative to a front side of the bilge.

2 . The isolation transfer cabin for interventional operation according to claim 1 , wherein;
a cross section of the hatch is an arch with a flattened top.

3 . The isolation transfer cabin for interventional operation according to claim 1 , wherein;
the hatch further comprises a hatch cover and a reinforcement device fixed on the hatch cover; wherein the reinforcement device includes a plurality of lateral support plates and a plurality of longitudinal support rods; wherein the plurality of lateral support plates are installed at intervals along a length direction of the hatch cover and the plurality of longitudinal support rods are installed at intervals along a perimeter direction between the lateral support plates; wherein the lateral support plates and the longitudinal support rods are perpendicular to each other and are fixedly connected via connecting pieces; and wherein a top surface of a lateral support plates is flat and both end surfaces of the lateral support plate are symmetrical arcs which are concentric with each other.

4 . The isolation transfer cabin for interventional operation according to claim 3 , wherein;
the connecting pieces include a connecting bracket and connecting screws; wherein the connecting bracket is fixed on the lateral support plates via the connecting screws; wherein the longitudinal support rods are supported by the connecting bracket and fixed thereon; and wherein the lateral support plates and the longitudinal support rods are both fixed on an outer wall of the hatch.

5 . The isolation transfer cabin for interventional operation according to claim 1 , further comprises:
a drive device for controlling opening or closing of the hatch,
wherein the drive device includes a connecting rod and a driving component;
wherein the connecting rod is fixedly mounted on bottom of the rear side of the hatch via a mounting base;
wherein one end of the connecting rod is connected to a support rib fixedly mounted on the left bulkhead; and
wherein an output end of the driving component is coupled to the connecting rod to drive the hatch to open or close.

6 . The isolation transfer cabin for interventional operation according to claim 1 , wherein:
the hatch is further provided on at least one side with one or more lead wire access devices, wherein each of the lead wire access devices are provided with lead wire access interfaces.

7 . The isolation transfer cabin for interventional operation according to claim 1 , wherein;
a wire in/out device for connecting a wire into the cabin is provided on a top of the hatch; wherein the wire in/out device includes a flexible sleeve and an end cap assembly; and wherein a bottom of the flexible sleeve is connected to the top of the hatch in a sealed manner; wherein a top of the flexible sleeve is connected to the end cap assembly in a sealed manner; and wherein the end cap assembly is connected to the top of the hatch in a detachably sealed manner.

8 . The isolation transfer cabin for interventional operation according to claim 7 , wherein;
the end cap assembly includes an end cap, a sealing plug, a sealing collar, and a sealing ring; wherein a bottom of the end cap is connected to the top of the hatch in a detachably sealed manner; wherein the sealing collar is detachably embedded and fit on the end cap; wherein a bottom of the sealing collar is provided with an annular groove; wherein a top of the flexible sleeve is pressed into the annular groove by means of the sealing ring; wherein the sealing plug is concentrically embedded and installed on the sealing collar; wherein the sealing plug is formed by splicing two half-frustum sealing plates together, both of which are provided with a semicircular recess; and wherein the semicircular recesses on both of the sealing plates cooperate to form a circular through groove for the wire to pass through.

9 . The isolation transfer cabin for interventional operation according to claim 7 , wherein
the flexible sleeve is made of plastic film.
