As shown in Figure 5, the second housing 22 with in the cylinder recess 44 of large-diameter portion 42, be inserted with the part of the first housing 21, particularly state and this first housing 21 of the part of cap 29 sides in the first housing 21 link.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, at this moment, the spray nozzle part 48 of the second housing 22 disposes in the mode that the valve member 30 towards the first housing 21 extends.
In the adapter 20 of said structure, by the second housing 22 is relatively moved along axis direction with respect to the first housing 21, thereby can make the second housing 22 be communicated with position (with reference to Fig. 5 (a)) between switching with non-with respect to the relative position of the first housing 21 being communicated with position (with reference to Fig. 5 (b)).When carrying out described relatively moving, jut 37 moves along path of navigation 53, be at above-mentioned relative position in the situation of non-connection position, become jut 37 be arranged in path of navigation 53 a side opposite with minor diameter part 43 sides (first housing 21 sides) the end and with the state of path end face 56b butt.In addition, in this case, under the effect of path protuberance 58, jut 37 is suppressed with the situation that path 54 enters to mounting or dismounting from path of navigation 53.On the other hand, be in the situation that is communicated with the position at above-mentioned relative position, become jut 37 be arranged in path of navigation 53 minor diameter part 43 sides (opposition side of the first housing 21) the end and with the state of path end face 56a butt.
Next, non-connected state and the connected state of adapter 20 are described respectively.
At first, shown in Fig. 5 (a), when adapter 20 was in non-connected state, spray nozzle part 48 was with respect to valve member 30 configured separate, was formed with the gap of regulation between the leading section of spray nozzle part 48 and valve member 30.At this moment, spray nozzle part 48 is in the state of the valve port 39 that does not pass valve member 30, and valve port 39 is in inaccessible state.That is, the first path 40 of the first housing 21 is by valve member 30 obturations, 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 20 outside connections of adapter.
On the other hand, shown in Fig. 5 (b), when adapter 20 was in connected state, spray nozzle part 48 passed the valve port 39 of valve member 30, became thus the state that the first path 40 and alternate path 50 are interconnected.Under the logical 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.At this moment, the inner peripheral surface of the valve port 39 of valve member 30 and the outer peripheral face of spray nozzle part 48 connect airtight mutually, and the air-tightness between described two sides is guaranteed.
As mentioned above, in above-mentioned adapter 20, be connected with air feed pipe arrangement 16 at the first housing 21, be connected with the syringe 25 of air supply pump 24 at the second housing 22.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 insertion state, on the inner peripheral surface of air feed pipe arrangement 16 by bonding the first path 40 that is fixed on the first housing 21.Thus, connecting air feed pipe arrangement 16, the first paths 40 at the first housing 21 is communicated with air feed pipe arrangement 16.
In addition, be connected with the oral area 25a (with reference to Fig. 4) of syringe 25 at the connecting portion 49 of the second housing 22.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, connect syringe 25 at the second housing 22, alternate path 50 is communicated with syringe 25.
Next, the using method of hemostasis utensil 10 described.At this, suppose to penetrate the situation of stopping blooding as the hemostasis object in the position with this will guiding cover and penetrate under the state of tremulous pulse of upper arm parts.In addition, describe centered by the operation when air bag 13 air supplies being made air bag 13 expand especially at this.
When stopping blooding operation, at first, with air bag 13 with as penetrating under the state that the position offsets of hemostasis object position belt body 11 is wrapped in upper arm parts, and by face button 14 that belt body 11 is fixing.
Next, use air supply pump 24 to air bag 13 air supplies and fill the operation of air to air bag 13.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 by carrying out repeatedly (be twice at this) air supply of air bag 13 is carried out to the fills with air of air bag 13.
Particularly, at first, as the air feed operation first time, the relative position of the second housing 22 in the adapter 20 with respect to the first housing 21 is being made as under the state of non-connection position, pull air supply pump 24 piston 26 and to the air of syringe 25 interior filling ormal weights.For example, to syringe 25 interior filling 35cm
3Air.Then, the second housing 22 is switched to from non-connection position with respect to the relative position of the first housing 21 be communicated with the 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.And, under this connected state, by piston 26 being pressed in the syringe 25 and the air in this syringe 25 being supplied with to air bag 13.
Next, as the air feed operation second time, again the second housing 22 is switched to non-connected state with respect to the relative position of the first housing 21 from connected state, and to air, for example 35cm of syringe 25 interior filling ormal weights
3Air.Then, the second housing 22 switched to from non-connection position again with respect to the relative position of the first housing 21 be communicated with the position, by piston 26 is carried out push operation the air in the syringe 25 are supplied with (replenishing) to air bag 13.Thus, in air bag 13, fill ormal weight (70cm by the air feed operation that amounts to twice
3) air, air bag 13 becomes the swelling state of regulation.And, thereby utilize the air bag 13 hemostasis by compression object positions of this expansion to carry out the hemostasis at this position.
Then, the second housing 22 is switched to non-connected state with respect to the relative position of the first housing 21 from connected state.Thus, the valve port 39 of blocking valve member 30 prevents the adverse current from the air of air bag 13.Therefore, the swelling state of air bag 13 is maintained, and the hemostasis at hemostasis object position is proceeded.
From the hemostasis at the object position that begins to stop blooding to having passed through official hour during this, confirm the hemostasis state at hemostasis object position, and carry out the adjustment of the level of compression of air bag 13 according to this hemostasis state.For example, in the situation of fully not stopped blooding in hemostasis object position, air bag 13 is replenished the level of compression that air improves 13 pairs of hemostasis of air bag object position.Particularly, the relative position of the second housing 22 with respect to the first housing 21 is being made as under the state of non-connection position, to syringe 25 interior filling air, then above-mentioned relative position switched to and be communicated with the position and the air in the supplementary injection device 25 in the air bag 13.On the other hand, crossing strong to the compressing at hemostasis object position and making in the situation of patient's pain, reducing level of compression to hemostasis object position by a part of removing the air in the air bag 13.Particularly, the second housing 22 switched to respect to the relative position of the first housing 21 be communicated with the position, by pulling piston 26 with the part of the air in the air bag 13 to syringe 25 interior attractions.After the adjustment of level of compression finishes, the second housing 22 is switched to non-connection position with respect to the relative position of the first housing 21.
From beginning hemostasis through the stipulated time affirmation of state (hemostasis during) after, the second housing 22 is taken off from the first housing 21.When taking off, the second housing 22 that is in non-connection position is rotated centered by its axis, thereby make jut 37 enter mounting or dismounting with path 54 (specifically being the part of radially extending of mounting or dismounting with path 54) from path of navigation 53, then the second housing 22 layback opposite with the first housing 21 on the axis direction dragged and with jut 37 to mounting or dismounting with pulling out outside the path 54 (specifically being the part along the axis direction extension of mounting or dismounting with path 54).Need to prove, when making the second housing 22 rotation, control operating portion 47 and make this second housing 22 rotations.Thus, take off air supply pump 24 from hemostasis utensil 10, finish a series of operation.
According to the structure of present embodiment described above in detail, can access following excellent results.
The adapter 20 of present embodiment constitutes, and possesses the first housing 21 that is connected with air feed pipe arrangement 16 and the second housing 22 that is connected with the syringe 25 of air supply pump 24, and described each body 21,22 is assembled in the mode that can install and remove.And, under described assembled state, can with the second housing 22 with respect to the relative position of the first housing 21 connection position that the first path 40 and alternate path 50 are communicated with switch described each path 40,50 disconnected non-connections between the position, when above-mentioned relative position was in non-connection position, air can flow into respect to alternate path 50.Thus, when when air bag 13 is replenished air, air bag 13 being carried out for the second time later air Injection, can under the states of two bodies 21,22 assemblings, above-mentioned relative position be switched to non-connection position and to syringe 25 interior filling air, then, above-mentioned relative position is switched to be communicated with the position and the air in the syringe 25 are supplied with (replenishing) to air bag 13.At this moment, when the replenish air of carrying out to air bag 13, need not to carry out syringe 25 is taken off or again connects loaded down with trivial details like this operation from adapter 20, therefore can easily carry out the operation that air bag 13 is replenished air.
In addition, because the first housing 21 can be installed and removed mutually with the second housing 22, therefore can keep under the first housing 21 and the state that air feed pipe arrangement 16 sides are connected, keep under the second housing 22 and the state that syringe 25 sides are connected enforcement for a series of operation of stopping blooding.For connecting, this mistake that medical apparatus mistake beyond syringe 25 leading sections and the hemostasis utensil is connected when preventing from stopping blooding operation such unfavorable condition, syringe 25 leading sections can be described as favourable structure.That is, although the oral area 25a of syringe 25 is the structure that conforms on the specification with the connecting portion 49 of the second housing 22 as described above, as long as conforming to, specification then also can link with hemostasis utensil medical apparatus in addition.For this point, by like that syringe 25 and adapter 20 (second housing 22) is affixed as mentioned above, just can prevent reliably that described mistake from connecting.
When the second housing 22 is made as non-connection position with respect to the relative position of the first housing 21, owing to limited the releasing of two bodies 21,22 assembling, therefore with after fills with air is in the air bag 13, can under syringe 25 and state that adapter 20 (second housing 22) is being connected, syringe 25 and air bag 13 be held in unconnected state.In this case, from being filled, air bag 13 can be described as preferred structure when after air begin through the stipulated time air bag 13 being replenished air.
Be formed with path of navigation 53 at the second housing 22, be provided with the jut 37 that is directed path 53 guiding at the first housing 21.And, in the second housing 22, make the second housing 22 with respect to the relative position of the first housing 21 from non-connection position when being communicated with the position displacement, a side path end face 56a limits the displacement of crossing this connection position among each path end face 56a, 56b of the tunnel end of the both sides by regulation path of navigation 53.And, make above-mentioned relative position when being communicated with the position to the displacement of non-connection position, the path end face 56b by the opposing party limits the displacement of crossing this non-connection position.In this case, can suitably carry out the second housing 22 is communicated with the operation of position between switching with non-with respect to the relative position of the first housing 21 being communicated with the position.In addition, carry out the displacement restriction of above-mentioned relative position by each path end face 56a, the 56b that utilizes path of navigation 53, thus simplification that can implementation structure and obtain simultaneously above-mentioned effect.

(4) in the respective embodiments described above, use valve member 30 as closure member, but also can use other closure member.For example, as shown in figure 11, also can use the check-valves 141 of duck-beak type as closure member.Described check-valves 141 has the valve port 141a of slit-shaped.Valve port 141a becomes at ordinary times inaccessible state under the effect of the elastic force of check-valves 141, the pressure differential in the front and back of check-valves 141 is timing, be the pressure in pressure ratio downstream of upstream side of check-valves 141 opening when large.
In Figure 11, in the first housing 21 (main part 28), alternate path 50 this check-valves 141 is set midway, the ratio check-valves 141 in alternate path 50 is by the end of the second housing 22 sides, specifically be provided with the circular containment member 142 that is made of silicone rubber in the end of the second housing 22 sides of alternate path 50.The state setting that containment member 142 connects airtight with the inner peripheral surface of its outer peripheral face and alternate path 50, its internal diameter is less than the external diameter of spray nozzle part 48.Need to prove, in Figure 11, for convenience of description, only illustrate spray nozzle part 48 for the second housing 22.
In above-mentioned structure, the second housing 22 can switch between these three positions, the 3rd position shown in the second position shown in the primary importance shown in Figure 11 (a), Figure 11 (b), Figure 11 (c) with respect to the relative position of the first housing 21.And in order to carry out the switching of described three positions, the structure of the path of navigation also structure from above-mentioned the first embodiment is different.Particularly, shown in Figure 11 (a-2)～(c-2), this routine path of navigation 146 therein way has the via intermedia 150 that radially extends, and is connected with two path of navigation sections 148,149 of extending along axis direction via this via intermedia 150.Two path of navigation sections 148,149 extend to opposition side on axis direction from the both ends of middle path 150 respectively, particularly, the first path of navigation section 148 extends to the opposition side of the first housing 21, and the second path of navigation section 149 extends to the first housing 21 sides.
In above-mentioned structure, shown in Figure 11 (a-1), when above-mentioned relative position was in primary importance, the spray nozzle part 48 of the second housing 22 separated at axis direction with respect to the first housing 21, and the first path 40 and alternate path 50 become non-connected state.At this moment, the jut 37 of the first housing 21 is arranged in the tunnel end of the first housing 21 sides of the second path of navigation section 149.
In addition, shown in Figure 11 (b-1), when above-mentioned relative position is in the second position, becomes spray nozzle part 48 and pass the inside of containment member 142 and the state that separates from check-valves 141.At this moment, the inner peripheral surface of the outer peripheral face of spray nozzle part 48 and containment member 142 becomes tightlock status, thus, become the state that the space between the check-valves 141 and containment member 142 in the first path 40 (below, be called dead-air space 153) is cut off with respect to the ventilation of outside.And alternate path 50 is communicated with this dead-air space 153.Under this state, when passing through air supply pump 24 to dead-air space 153 air supply, the pressure in this space 153 raise, and the valve port 141a of check-valves 141 opens.Thus, can carry out to the air supply of air bag 13.In addition, under the described second position, the jut 37 of the first housing 21 is arranged in the tunnel end of the first housing 21 sides of the first path of navigation section 148.
In addition, shown in Figure 11 (c-1), when above-mentioned relative position is in the 3rd position, become that spray nozzle part 48 passes the valve port 141a of check-valves 141 and state that the first path 40 and alternate path 50 are communicated with.Under this state, by pulling the piston 26 of air supply pump 24, thereby can attract the air in the air bag 13.Thus, in the situation that the hemostasis processing of carrying out based on hemostasis utensil 10 finishes, can air bag 13 be shunk by described attraction.In addition, under described the 3rd position, the jut 37 of the first housing 21 is arranged in the tunnel end of a side opposite with the first housing 21 sides of the first path of navigation section 148.
