As another improvement project of this utility model, on the inwall that mixes medicine card body, be symmetrically arranged with at least two and be barb-like and be used to prevent the anti-slide fastener that medicament reservoir is loosening.
The beneficial effect of this utility model is: this utility model is with sealing shroud on the needle point below the mixed medicine card body; Sealing shroud makes the needle point that mixes medicine card body below be in sealing state; Can make passage and mixed medicine card body in the dosing crosspointer be in sealing state through sealing cover and the diaphragm seal that mixes the port setting of medicine card body, effectively avoid being polluted in passage and the mixed medicine card body in the dosing crosspointer; Protective sleeve is enclosed within outside the sealing shroud and is fixed on and mixes on medicine card body or the dosing crosspointer, and it is clean with following pin that this protective sleeve plays a part the protection sealing shroud, can avoid sealing shroud under the effect of external force, to come off from needle point; When mixing medicine; Directly with the sealing-plug of tip alignment infusion vessel, exert pressure rapidly behind the dismounting protective sleeve, needle point is advanced to sealing-plug; Along with needle point punctures downwards; Sealing shroud is punctured and is moved up along the following pin that mixes under the medicine card body, does not influence the continuation puncture of pin down, helps medicament reservoir and is connected with infusion vessel is aseptic.
Description of drawings
Fig. 1 is the cutaway view with the crosspointer drug feeding device of type self-destroyed sealing shroud.
In the accompanying drawing: 1-mixed medicine card body; 2-dosing crosspointer; 3-sealing shroud; 4-protective sleeve; 5-diaphragm seal; 6-anti-slide fastener; 7-cutting ferrule; 8-annular rubber cushion.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment this utility model is done to describe in further detail.
As shown in Figure 1, with the crosspointer drug feeding device of type self-destroyed sealing shroud, comprise cup-like structure mixed medicine card body 1, be arranged on and mix medicine card body 1 bottom and along dosing crosspointer 2, sealing shroud 3 and the protective sleeve 4 of the axial setting that mixes medicine card body 1.Dosing crosspointer 2 is one-body molded with mixed medicine card body 1, and sealing shroud 3 is enclosed within dosing crosspointer 2 and is positioned on the needle point that mixes medicine card body 1 below, and protective sleeve 4 is enclosed within outside the sealing shroud 3 and is fixed on and mixes on medicine card body 1 or the dosing crosspointer 2.In the present embodiment, the bottom of mixing medicine card body 1 has cutting ferrule 7, and the mode of protective sleeve 4 through clamping is enclosed within on the cutting ferrule 7 and with cutting ferrule 7 and is sealed and matched, and only needs during protection sealing shroud 3 protective sleeve 4 is fastened on the cutting ferrule 7 to get final product; Only need when mixing medicine protective sleeve 4 is pulled up from cutting ferrule 7.Certainly also can protective sleeve 4 be fixed on the following pin that mixes under the medicine card body 1.The port of mixing medicine card body 1 is provided with diaphragm seal 5.
Sealing shroud 3 adopts elasticity, toughness or soft material to process.Sealing shroud 3 has elasticity or toughness, can be unlikely to get loose from line slip using overall process all closely to contact with following pin outer wall.
Mix in the medicine card body 1 and be provided with annular rubber cushion 8, annular rubber cushion 8 is enclosed within outside the dosing crosspointer 2.Because of this annular rubber cushion 8 has better elastic; In the time of in medicament reservoir snaps in mixed medicine card body 1; Anti-slide fastener 6 on this annular rubber cushion 8 and the mixed medicine card body 1 can prevent effectively that medicament reservoir is loosening, and annular rubber cushion 8 seals the grafting site between medicament reservoir and the mixed medicine card body 1 fully, and the medicinal liquid seepage takes place when avoiding mixing medicine; Also but the absolutely gas-tight property in the medicament reservoir behind the mixed medicine of strict guarantee is stopped microbiological contamination danger
On the inwall that mixes medicine card body 1, being symmetrically arranged with at least two is barb-like and is used to prevent the anti-slide fastener 6 that medicament reservoir is loosening.In the present embodiment, on the inwall that mixes medicine card body 1, be symmetrically arranged with six anti-slide fasteners 6.When mixing medicine, medicament reservoir snapped in mix in the medicine card body 1, medicament reservoir can effectively avoid medicament reservoir in mixed medicine card body 1, to withdraw from or become flexible to opposite direction under the inhibition of anti-slide fastener 6.
Because of on the needle point below the mixed medicine card body 1, being with sealing shroud 3; Sealing shroud 3 makes the needle point that mixes medicine card body 1 below be in sealing state; The diaphragm seal 5 of the port setting through sealing cover 3 and mixed medicine card body 1 can make passage and mixed medicine card bodies 1 in the dosing crosspointer 2 be in sealing state, effectively avoids being polluted in passage and the mixed medicine card body 1 in the dosing crosspointer 2.Protective sleeve 4 is enclosed within outside the sealing shroud 3 and is fixed on and mixes on the medicine card body 1, and this protective sleeve 4 plays a part protection sealing shroud 3, avoids sealing shroud 3 under the effect of external force, to come off from needle point.When mixing medicine; Directly will descend needle point to stab on the sealing-plug of infusion vessel after removing diaphragm seal 5 and protective sleeve 4; Along with following needle point punctures downwards, sealing shroud 3 is punctured and is moved up along the following pin that mixes under the medicine card body 1, helps medicament reservoir and is connected with infusion vessel is aseptic.
Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation this utility model; Although with reference to preferred embodiment this utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of this utility model; And not breaking away from the aim and the scope of this utility model technical scheme, it all should be encompassed in the middle of the claim scope of this utility model.
