Next, use Fig. 5 that the connecting structure of the first housing 21 in adapter 20 and the second housing 22 is described.For the adapter 20 of present embodiment, under its connecting state, switch between the non-interconnected position that the connection position that the second housing 22 can be communicated with at the first path 40 and alternate path 50 relative to the relative position of the first housing 21 is not communicated with the first path 40 and alternate path 50.In Figure 5, adapter 20 when () represents that the second housing 22 is in non-interconnected position relative to the relative position of the first housing 21 is a (following, adapter 20 also referred to as non-interconnected state) structure, (a-1) be the front view representing this structure, (a-2) is longitudinal sectional view.On the other hand, in Figure 5, b () represents that the adapter 20 that above-mentioned relative position is in when being communicated with position is (following, adapter 20 also referred to as connected state) structure, (b-1) be the front view representing this structure, (b-2) is longitudinal sectional view.
As shown in Figure 5, the second housing 22 links with the state and this first housing 21 that are inserted with a part for cap 29 side in a part, the specifically first housing 21 of the first housing 21 in the cylinder recess 44 of large-diameter portion 42.Under described connecting state, the jut 37 of the cap 29 of the first housing 21 enters in the path of navigation 53 of the second housing 22, can be directed along this path of navigation 53.In addition, now, the spray nozzle part 48 of the second housing 22 configures in the mode extended towards the valve member 30 of the first housing 21.
In the adapter 20 of said structure, by making the second housing 22 carry out relative movement in the axial direction relative to the first housing 21, thus the second housing 22 can be made to switch between connection position (with reference to Fig. 5 (b)) and non-interconnected position (with reference to Fig. 5 (a)) relative to the relative position of the first housing 21.When carrying out described relative movement, jut 37 moves along path of navigation 53, when above-mentioned relative position is in non-interconnected position, becomes jut 37 and be arranged in the end of the side (first housing 21 side) contrary with minor diameter part 43 side of path of navigation 53 and the state abutted with path end face 56b.In addition, in this case, under the effect of path protuberance 58, the situation that jut 37 enters from path of navigation 53 to mounting or dismounting path 54 is suppressed.On the other hand, when above-mentioned relative position be in be communicated with position, become jut 37 and be arranged in the end of minor diameter part 43 side (opposition side of the first housing 21) of path of navigation 53 and the state abutted with path end face 56a.
Next, the non-interconnected state of adapter 20 and connected state are described respectively.
First, as shown in Fig. 5 (a), when adapter 20 is in non-interconnected state, spray nozzle part 48, relative to valve member 30 configured separate, is formed with the gap of regulation between the leading section of spray nozzle part 48 and valve member 30.Now, spray nozzle part 48 is in not through the state of the valve port 39 of valve member 30, and valve port 39 is in inaccessible state.That is, the first path 40 of the first housing 21 is inaccessible by valve member 30, and the alternate path 50 of this path 40 and the second housing 22 becomes unconnected state.In addition, under described unconnected state, alternate path 50 is communicated with cylinder recess 44, and then via path of navigation 53 and adapter 20 ft connection.
On the other hand, as shown in Fig. 5 (b), when adapter 20 is in connected state, spray nozzle part 48, through the valve port 39 of valve member 30, becomes the state that the first path 40 is interconnected with alternate path 50 thus.Under the state of inserting of described spray nozzle part 48, the valve port 39 of valve member 30 is resisted the elastic force of valve member 30 and is pressed off under the effect of spray nozzle part 48.Now, the inner peripheral surface of the valve port 39 of valve member 30 and the outer peripheral face of spray nozzle part 48 touch mutually, and the air-tightness between described two sides is guaranteed.
As mentioned above, in above-mentioned adapter 20, the first housing 21 is connected with air feed pipe arrangement 16, the second housing 22 is connected with the syringe 25 of air supply pump 24.In the first path 40 of the first housing 21, be inserted with air feed pipe arrangement 16 (with reference to Fig. 3) in the end of the opposition side of the second housing 22.Under described insert state, air feed pipe arrangement 16 is by bonding and be fixed on the inner peripheral surface of the first path 40 of the first housing 21.Thus, the first housing 21 connects air feed pipe arrangement 16, first path 40 to be communicated with air feed pipe arrangement 16.
In addition, the connecting portion 49 of the second housing 22 is connected with the oral area 25a (with reference to Fig. 4) of syringe 25.At the internal thread part of the oral area 25a of the fastening syringe 25 of the external thread part 49a of connecting portion 49, under this tightening state, connecting portion 49 and oral area 25a are by bonding and fixing.Thus, the second housing 22 connects syringe 25, alternate path 50 is communicated with syringe 25.
Next, the using method of hemostatic device 10 is described.At this, suppose to penetrate the situation of carrying out as hemostasis object stopping blooding in position using this under the state that guiding cover is penetrated the tremulous pulse of upper arm parts.In addition, this especially to make air bag 13 expand to air bag 13 air supply time operation centered by be described.
When carrying out hemostasis operation, first, using air bag 13 with as object position of stop blooding penetrate the state that position offsets under belt body 11 is wrapped in upper arm parts, and detain 14 by face belt body 11 fixed.
Next, carry out using air supply pump 24 to fill the operation of air to air bag 13 to air bag 13 air supply.In the present embodiment, as mentioned above, because the inner capacities of air bag 13 is larger than the inner capacities of the syringe 25 of air supply pump 24, therefore fill by carrying out repeatedly (in this case twice) air supply air carried out to air bag 13 to air bag 13.
Specifically, first, as first time air feed operation, under the state that the second housing 22 in adapter 20 is set to non-interconnected position relative to the relative position of the first housing 21, pull the piston 26 of air supply pump 24 and in syringe 25, fill the air of ormal weight.Such as, in syringe 25,35cm is filled 3air.Then, the second housing 22 is switched to connection position relative to the relative position of the first housing 21 from non-interconnected position.Thus, the spray nozzle part 48 of the second housing 22 passes the valve port 39 of valve member 30, and the first path 40 of the first housing 21 is communicated with the alternate path 50 of the second housing 22.Further, under this connected state, by piston 26 is pressed in syringe 25, the air in this syringe 25 is supplied to air bag 13.
Next, as the operation of second time air feed, again the second housing 22 is switched to non-interconnected state relative to the relative position of the first housing 21 from connected state, and fill air, the such as 35cm of ormal weight in syringe 25 3air.Then, the second housing 22 being switched to from non-interconnected position again relative to the relative position of the first housing 21 and is communicated with position, by carrying out push operation to piston 26, the air in syringe 25 being supplied (supplementing) to air bag 13.Thus, the air supplying operation by amounting to twice fills ormal weight (70cm in air bag 13 3) air, air bag 13 becomes the swelling state of regulation.Further, utilize the air bag 13 hemostasis by compression object position of this expansion thus carry out the hemostasis at this position.
Then, the second housing 22 is switched to non-interconnected state relative to the relative position of the first housing 21 from connected state.Thus, the valve port 39 of blocking valve component 30 prevents the adverse current of the air from air bag 13.Therefore, the swelling state of air bag 13 is maintained, and the hemostasis at hemostasis object position proceeds.
From stop blooding the hemostasis at object position to have passed through official hour during this, confirm the haemostatic state at hemostasis object position, and carry out the adjustment of the level of compression of air bag 13 according to this haemostatic state.Such as, when fully not stopping blooding to hemostasis object position, air is supplemented to improve the level of compression of air bag 13 to hemostasis object position to air bag 13.Specifically, under the state that the second housing 22 is set to non-interconnected position relative to the relative position of the first housing 21, in syringe 25, fill air, then above-mentioned relative position is switched to and be communicated with position and the air supplemented in air bag 13 in syringe 25.On the other hand, when making patient pain when crossing by force the compressing at hemostasis object position, the level of compression to hemostasis object position is reduced by a part for the air in removing air bag 13.Specifically, the second housing 22 being switched to relative to the relative position of the first housing 21 and is communicated with position, by pulling piston 26, a part for the air in air bag 13 being attracted in syringe 25.After the adjustment of level of compression terminates, the second housing 22 is switched to non-interconnected position relative to the relative position of the first housing 21.
From starting hemostasis, after the stipulated time (during the confirmation of haemostatic state), the second housing 22 to be taken off from the first housing 21.When taking off, first the second housing 22 being in non-interconnected position is made to rotate centered by its axis, thus make jut 37 enter mounting or dismounting path 54 (being specifically the part radially extended of mounting or dismounting path 54) from path of navigation 53, then side contrary with the first housing 21 on axis direction for the second housing 22 is pulled and jut 37 is pulled out outward to mounting or dismounting path 54 (being specifically the part extended in the axial direction of mounting or dismounting path 54).It should be noted that, when making the second housing 22 rotate, holding operating portion 47 and this second housing 22 is rotated.Thus, take off air supply pump 24 from hemostatic device 10, terminate a series of operation.
According to the structure of present embodiment described above in detail, following excellent results can be obtained.
The adapter 20 of present embodiment is configured to, and possesses the first housing 21 be connected with air feed pipe arrangement 16 and the second housing 22 be connected with the syringe 25 of air supply pump 24, and is assembled in the mode that can install and remove by described each body 21,22.And, under described assembled state, the relative position of the second housing 22 relative to the first housing 21 can be switched between the connection position that the first path 40 and alternate path 50 are communicated with and the disconnected non-interconnected position of described each path 40,50, when above-mentioned relative position is in non-interconnected position, air can flow into relative to alternate path 50.Thus, when the air Injection after second time being carried out to air bag 13 when supplementing air to air bag 13, under the state can assembled at two bodies 21,22, above-mentioned relative position is switched to non-interconnected position and fill air in syringe 25, then, above-mentioned relative position is switched to connection position and the air in syringe 25 is supplied (supplementing) to air bag 13.Now, when carrying out the replenish air to air bag 13, syringe 25 being taken off from adapter 20 without the need to carrying out or again connects operation loaded down with trivial details like this, therefore, it is possible to easily carry out operation air bag 13 being supplemented to air.
In addition, because the first housing 21 and the second housing 22 can be installed and removed mutually, a series of operation for stopping blooding therefore can be implemented under the state keeping the first housing 21 be connected with air feed pipe arrangement 16 side, under the state that keeps the second housing 22 to be connected with syringe 25 side.This for syringe 25 leading section and the medical apparatus beyond hemostatic device being connected such unfavorable condition when preventing from carrying out hemostasis operation by mistake, the mistake of syringe 25 leading section connect for can be described as favourable structure.That is, although the structure of the connecting portion 49 of the oral area 25a of syringe 25 and the second housing 22 as described above for specification conforms to, if specification conform to then also can with hemostatic device beyond medical apparatus link.For this point, by as described above by affixed to syringe 25 and adapter 20 (second housing 22), described connection by mistake just reliably can be prevented.
When the second housing 22 is set to non-interconnected position relative to the relative position of the first housing 21, owing to limiting the releasing of the assembling of two bodies 21,22, therefore air is being filled into after in air bag 13, under the state that can be connected at syringe 25 and adapter 20 (second housing 22), syringe 25 and air bag 13 is being held in unconnected state.In this case, can be described as preferred structure supplementing air to air bag 13 from filling air to air bag 13 after the stipulated time.
The second housing 22 is formed path of navigation 53, the first housing 21 is provided with the jut 37 that directed path 53 guides.And, in the second housing 22, when making the second housing 22 conjugate to connection position from non-interconnected position relative to the relative position of the first housing 21, limit the displacement of crossing this connection position by the path end face 56a of a side in each path end face 56a, 56b of the tunnel end of the both sides of regulation path of navigation 53.Further, when making above-mentioned relative position conjugate from connection position to non-interconnected position, the displacement of crossing this non-interconnected position is limited by the path end face 56b of the opposing party.In this case, can suitably carry out the second housing 22 being communicated with relative to the relative position of the first housing 21 operation switched between position and non-interconnected position.In addition, by the displacement restriction utilizing each path end face 56a, 56b of path of navigation 53 to carry out above-mentioned relative position, thus the simplification of structure can be realized and obtain above-mentioned effect simultaneously.
The adapter 20 of present embodiment is configured to, under the state containing the first housing 21 in the cylinder recess 44 of the second housing 22, two bodies 21,22 are assembled mutually, and be provided with the path of navigation 53 of the through slit-shaped of through-thickness in the surrounding wall portion 51 of surrounding cylinder recess 44.Further, when the second housing 22 becomes non-interconnected position relative to the relative position of the first housing 21, alternate path 50 is communicated with cylinder recess 44.In described structure, make cylinder recess 44 and adapter 20 ft connection via path of navigation 53.Further, when the second housing 22 is in non-interconnected position relative to the relative position of the first housing 21, because alternate path 50 is communicated with cylinder recess 44, therefore air can flow into relative to alternate path 50, namely air can flow into syringe 25.In this case, path of navigation 53 can be also used as the introducing port (blow vent) for being guided to alternate path 50 by air, thus the multifunction of path of navigation 53 can be realized.
