(about administration time effect)

Illustrate and use the nutrient administration group 1 of above structure to carry out the step of nutrient administration to patient.

First, the operators such as doctor or nurse are suspended on one end of sack 100 on support as shown in FIG. 1, make port one 01 with lid 15 together with towards below.On the other hand, make one end of tube for transfusion 30 through nozzle 20, one end engagement of tube for transfusion 30, in the engagement stage portion 2032 of nozzle body portion 21 inside, is extended from top ends 2033.And, also can before fabrication stage or outbound, in advance nozzle 20 be connected with tube for transfusion 30.

On the other hand, be connected on the pipe end of the regulation that is disposed in patient's side being arranged on tube for transfusion 30 another distolateral insertion sections 33.

Then, operator as shown in FIG. 2 limit makes bearing surface 200 mention nozzle 20 limits towards top to make not note interferingly with engagement pawl 153,154 angle that nozzle 20 rotates around axle center in conjunction with bead 201,202, and the bearing surface 200 that makes nozzle 20 and the bearing surface 161 of lid 15 connect (with reference to the first direction that in Fig. 2, the arrow by vertical direction represents).Thus and thus, operator makes nozzle 20 relatively move, contact with lid 15.Now, the protuberance 160 of lid 15 and sealing 155 (rib 155a～155c) insert the inside of nozzle body portion 21.

By carrying out above operation, the outer peripheral face of protuberance 160 becomes the state contacting liquid-tightly with the inner face of nozzle body portion 21, the inside of nozzle body portion 21 and the protuberance 160 and the sealing 155 and extraneous air isolation that cover 15, form nozzle 20 and the connection status of covering 15.

Then, operator is in order to fix (locking) by nozzle 20 and the connection status of lid 15, clip operating portion 205,206 with finger, make nozzle 20 relatively rotate to the angle (second direction representing with curvilinear arrow in reference to Fig. 2) of 60 ° around the axle center of nozzle 20 with respect to lid 15.Now, the inner peripheral surface limit of the outer peripheral face of protuberance 160 and nozzle body portion 21 maintains liquid-tight state limit and slides over each other, and relatively rotates around the axle center of nozzle 20.So, before above-mentioned rotation operation, be positioned at the engagement pawl 153,154 (with reference to Fig. 5 (a)) by direction of rotation upstream side than eaves portion 2013,2023, follow above-mentioned rotation operation to enter between bearing surface 200 and eaves portion 2013,2023, edge upwards pushes away eaves portion 2013,2023 limits away from the direction of bearing surface 200 and enters (with reference to each arrow of Fig. 5 (b)).So the final and engagement pawl abutting part 2011,2021 of engagement pawl 153,154 connects, and stops it to advance.The now protuberance 1531,1541 of engagement pawl 153,154 and be arranged on the recess 2014,2024 chimeric (Fig. 5 (c)) in eaves portion 2013,2023.Had this chimeric, nozzle 20 is over combination (locking) action of lid 15.

After block action is over, because nozzle 20 is combined with interconnected state securely with lid 15, be therefore not easy to throw off.

Wherein, Fig. 6 (a) is the state before locking, and Fig. 6 (b) be blocking, is respectively for illustrating that transfusion that nozzle 20 forms with the configuration relation of lid 15 with by rib 155a～155c (sealing 155) opens the figure of mechanism.In this figure, as representing nozzle 20 with the cross section structure that the line that is 120 ° through embeded

slot

3020b, 3020c, through the angle of the axle center rotation around nozzle body portion 21 dissects.And Fig. 7 (a), (b) represent respectively the configuration relation of nozzle 20 before locking, under blocking and lid 15, are the front view of looking down along the axle center of nozzle 20 from nozzle tip portion 2033.Fig. 7 (a), (b) dot the profile in conjunction with bead 201,202.

As above-mentioned Fig. 2, after just nozzle 20 being connected to and covering on 15, rib 155a～155c is only in the inside of nozzle body portion 21, in only chimeric with embeded slot 2030a～2030c state (with reference to Fig. 6 (a), Fig. 7 (a)).Under this state, if operator carries out above-mentioned block action for operating operation portion 205,206, make nozzle 20 rotate to the words of the angle of 60 ° with respect to lid 15 axle center taking nozzle body portion 21 around this axle as rotating shaft, each rib 155a～155c under the chimeric state of embeded slot 2030a～2030c together with nozzle 20 with rotation, in rotary moving to departing from 60° position, origin-location around above-mentioned rotating shaft.Follow this in rotary moving, the connecting portion 1550a～1550c that is positioned at rib 155a～155c root is cut off and ruptures.So internally there is (Fig. 6 (b), Fig. 7 (b)) near nozzle body portion 21 in gap 156a～156c.Wherein, Fig. 6 (b) represents: each rib 155a～155c is taking the axle center of nozzle body portion 21 as rotating shaft is in rotary moving to departing from the angle of 60 ° of original positions, result that connecting portion 1550a～1550c ruptures as having there is the lid 15 of gap 156a～156c.

As described above, follow block action in rotary moving by rib 155a～155c, connecting portion 1550a～1550c fracture, thus stream 159 is just communicated with nozzle 20 1 sides by gap 156a～156c.Keep during this period the liquid-tight state between the outer peripheral face of protuberance 160 and the inner peripheral surface of nozzle body portion 21.Hung down because sack as Fig. 1 100 makes to cover 15, therefore the nutrient in sack 100, at the internal circulation of lid 15 and nozzle body portion 21 under deadweight, can pass through tube for transfusion 30 to patient's side administration.Like this, nutrient administration group 1 becomes the administration that can start nutrient together with being over lid 15 block action with nozzle 20, even therefore in the time that the inner sealing of 15 pairs of sacks 100 of lid is disengaged, nutrient is also always isolated with extraneous air.Thus, owing to can positively avoiding that impurity when nutrient administration patient is sneaked into from extraneous air to nutrient through gap 156a～156c, therefore very effective on administration of health.Nutrient administration group 1 from lid is different to having at the necessary existing structure that covers perforate before nozzle connects, after nozzle 20 is connected with lid 15 and with covering in 15 locking is over, can removes in the sealing this point of covering 15 and can bring into play by leaps and bounds superior safety.

And, nozzle 20 and lid 15 only, by using special each other combination, each joint portion (be engagement pawl 153,153 and in conjunction with bead 201,202, sealing 155 and embeded slot 2030a～2030c) of forming closely here, just can normally connect and locking.Owing to requiring strict like this connection selectivity, even can not connect when therefore operator will be connected with configuration lid 15 to other tube for transfusion of patient by mistake, therefore can positively prevent the problem that mistake connects.Nutrient administration group 1 also can be brought into play high safety in this.

In addition, although lid 15 has connecting portion 1550a～1550c to rotate completely fracture, sealing 155 when separating because of nozzle 20, but due to rib 155a～155c with the chimeric state of embeded slot 2030a～2030c under keep, therefore can not flow to tube for transfusion 30 1 sides from the sealing 155 that covers 15 separation.

And, move and follow in the opening operation of this stream 159 for lid 15 and the combination of nozzle 20, as long as make them mobile just passable relative to each other.Therefore, can make to cover 15 situations about moving with respect to nozzle 20 or make nozzle 20 with respect to lid 15 situations about moving arbitrary situation under move.

Below by with the difference of example 1 centered by other examples of the present invention are described.

< example 2>

Then the Fig. 8 representing represents that nozzle 20A side is that Male Connector, lid 15A side are the example 2 that Female Connector forms.Although Fig. 8 to be shown in nozzle 20A top, lid 15A is shown in to below in order to illustrate, when use as shown in Figure 1, 2, the upper and lower relation changeabout of both configurations.

As with the difference of example 1, lid 15A is using the upper surface of columned lid base portion 151A as bearing surface 161A, that surrounds this bearing surface 161A erects cylindrical portion 163 peripherally.Wherein, adapt by the external diameter that makes the internal diameter of cylindrical portion 163 and the main part 21A of nozzle 20A, the main part 21A of nozzle 20A inserts the inside of (or being pressed into) cylindrical portion 163.Around the peristome 164 of cylindrical portion 163, be formed with a pair of

engagement pawl

153A, 154A with above-mentioned 153,154 same structures.Central authorities at bearing surface 161A form the sealing 155A same with 155 by the connecting portion same with 1550a～1550c, are formed with the gap being communicated with the stream of lid 15A under each rib 155a～155c.Above-mentioned stream and above-mentioned gap are respectively the structure same with 159 and 156a～156c.

On the other hand, nozzle 20A is made up of main part 21A and a pair of

combination bead

201A, 202A.

Main part 21A is cylinder, and on face thereunder, configuration and the bearing surface 200A that the bearing surface 161A of lid 15A connects, arrange sign face 204A on face up.

Character and the arrow same with 204 are implemented in surface at the face of sign 204A, are connected with in the central tube for transfusion 30.

Be the structure same with 201,202 in conjunction with

bead

201A, 202A, for can with the structure of engagement pawl 153,154 combinations, be equally spaced formed on the side of main part 21A.In the structure shown in Fig. 8, covered by box-shaped framework in conjunction with the element of

bead

201A, 202A, cannot see from outside.

In addition, surround sign face 204A circle-shaped rib (cylindrical portion) around although the structure shown in Fig. 8 erects, this not necessarily.

In the central authorities of bearing surface 200A, be formed with and there is shape that can be chimeric with each rib 155a～155c of sealing 155, the embeded slot 2030A of radial (three wedge-likes).

And, axially running through bearing surface 200A and indicating face 204A to be formed with and amount to 3 nozzle bore L1, L2, L3 along its cylinder on main part 21A.Each peristome that this nozzle bore L1, L2, L3 make bearing surface 200A side nozzle 20A is latched to cover on 15 after be formed on sealing 155 under above-mentioned gap be communicated with and make to indicate each peristome of face 204A side and the internal communication of tube for transfusion 30 and form.

Although nozzle bore L1, L2, L3 are here circular section shape, also can adopt the shape of square-section, or carry out the adjusting of nozzle hole count increase etc.

There is the lid 15A and nozzle 20A of above structure in use when, also play all effect roughly the same with nutrient administration group 1.

That is, when operator, nozzle 20A being connected to and covering on 15, note

engagement pawl

153A, 154A and non-interference in conjunction with

bead

201A, 202A, the main part 21A of nozzle 20A is squeezed in the cylindrical portion 163 of covering 15.Then, sealing 155A is fitted in embeded slot 2030A, completely the 21A of nozzle body portion is squeezed in cylindrical portion 163, until the mutual butt of bearing

surface

200A, 161A.

By this operation, the side of the 21A of nozzle body portion contacts liquid-tightly with the inner face of cylindrical portion 163, reaches nozzle 20A and covers being connected of 15A.

Then, in the situation that maintaining this connection status, operator makes nozzle 20A rotate to the angle of 60 ° around the axle center of this nozzle 20A, make

engagement pawl

153A, 154A respectively with in conjunction with

bead

201A, 202A combination, by carrying out like this block action.Follow this block action, be fitted to sealing 155A in fitting portion 2030A in rotary moving, above-mentioned connecting portion fracture, above-mentioned gap in the face of nozzle bore L1, L2, present L3.Thus, the nutrient in sack 100 can be passed to tube for transfusion 30 1 sides by nozzle bore L1, L2, L3.

By above action, also same with example 1 in example 2, the nutrient in sack 100 does not contact with extraneous air in use, can remove the sealing of covering 15A, prevent that foreign body from sneaking into the pollution of the nutrient causing, can be wholesomely by nutrient administration patient.And because the sealing of lid 15A is removed and always reached under the state of lid 15A and nozzle 20A connection status, therefore nutrient also can prevent from covering the problem outside escaping to such as 15 above-mentioned gap.And example 2 structurally has strict connection selectivity mutually owing to covering 15A and nozzle 20A, therefore can also play the effect that positively prevents lid 15A to be connected to the problem on different tube for transfusions by mistake.

In addition, although Fig. 8 for example understands the structure that forms fitting portion 2030A and nozzle bore L1, L2, L3 on nozzle 20A, but also can as the nozzle of example 1 20, form the space cylindraceous (stream) being communicated with tube for transfusion 30 in the inside at the 21A of nozzle body portion, embeded slot 2030a～2030c that formation can be chimeric with rib 155a～155c on this inwall cylindraceous.

< other business >

Although above-mentioned example 1 shows, 3 rib 155a～155c are combined into the sealing 155 that radial (three wedge-likes) forms, the radical that is arranged to radial rib is not limited to this, can be both 1 or 2, can be also more than 4.

And, also can replace rib is set, and with the axis parallel ground of nozzle, make length direction evenly erect bar (column), the root of this bar around, form the connecting portion being formed by thinner wall section, under bar, formation is equivalent to the hole in above-mentioned gap.In this case, by nozzle, form can insertion rod recess replace above-mentioned embeded slot, make each bar remove the design of the sealing of covering etc. along with block action fractures, reveals gap (hole) at root.And, can also utilize and there is single three-dimensional shape the combination of sealing and the embeded slot that can be chimeric with it of (rectangular-shaped, polygon prism shape etc.).But, adopting any structure in the situation that, all to note also keeping the inside of the nozzle body portion of liquid-tight state, stream opening not contact this point with extraneous air nozzle being connected to after covering.

In addition, in order to improve the liquid-tight property between lid and nozzle, can be for example arrange the seal members such as liner at bearing surface or the side face of protuberance etc. of lid on any.And, the smooth surface treatment of contact surface that can also be used for making lid and nozzle to contact with each other.

And, about lid, protuberance is not set on bearing surface, directly sealing is set on bearing surface, also can prevent stream opening time, stream contacts with extraneous air.But, in order also to guarantee liquid-tight property good between lid and nozzle before locking, wish to arrange protuberance, increase the liquid-tight contact area of lid and nozzle.Therefore the design of, carrying out that as example 2 cylindrical portion contacts liquid-tightly with nozzle body portion etc. is preferred.

And nozzle and lid are not limited to uses engagement pawl and the structure in conjunction with bead combination, also can use integrated structure in addition.For example, also can lid be combined with nozzle with being threadedly engaged with.
