Described valve body 12 can be made up of polymethyl methacrylate (PMMA or acrylic acid), acronitrile-butadiene-styrene (ABS), polrvinyl chloride (PVC) or other medical grade polymer any well known in the art.Described sheath pipe 11 can be made up of PEP (FEP) or the high density polyethylene (HDPE) extruded or other material any with suitable bio-compatibility.Sheath pipe 11 can have the diameter of any size.Sheath pipe 11 can be connected with valve body 12 by any suitable mode, as undertaken connecting or being in clamping connection by being provided with flange by bonding, welding, or connected by any suitable mode that those skilled in the art can expect.
Shown in Fig. 3 is the structural representation of haemostatic valve 10 according to preferred embodiment of the present utility model; Shown in Fig. 4 is sectional view along A-A line in Fig. 3.As shown in Figure 2 and Figure 4, described valve body 12 comprises far-end and near-end, is provided with proximal end cap 13 at the near-end of described valve body 12, is provided with distal end cap 16 at the far-end of described valve body 12.Described proximal end cap 13 and distal end cap 16 can be fixed on valve body 12, as fixed by gluing or welding manner, or are fixed by any suitable mode that those skilled in the art can expect.
Described two valve blocks 14,15 are made by elastic polymer material, as silica gel, rubber, polyurethane or other suitable material.Its middle valve plate 14 is provided with aperture 41, and the diameter range of described aperture is 0.1mm to 1.5mm.Preferably, described aperture is located at the middle part of described valve block with holes 14.Another valve block 15 described is provided with otch 51, and the form of otch can be linear cuts, as any suitable shape that straight line or shaped form etc. it may occur to persons skilled in the art that.Described curve can be any suitable shapes such as circular arc line.Described linear cuts refers to that the otch be located on valve block is harmless otch.Described linear cuts can be one, two or more pieces, and described otch can be pass-through cuts, also can be the non-penetrating otch being distributed in described band otch valve block 15 both sides.Described non-penetrating otch refers to that the degree of depth of described linear cuts is less than the thickness of valve block, and it does not switch to the another side of valve block.Preferably, described otch is linear incision, and more preferably, described otch is word otch or a cross recess.This otch not only structure is simple, also reliable and stable.Described linear cuts can be located at the middle part of described valve block, also can be located at other position on described valve block.Preferably, described linear cuts is located at the middle part of described band otch valve block 15, and its length range is 1mm to 5mm.Described linear cuts perpendicular to described valve block, also can favour described valve block when cutting.Described inclination refers to parallel with the normal plane of valve block plane.
According to this utility model one preferred embodiment, the otch 51 on described valve block 15 is the non-penetrating otch of two words, is distributed in the both sides of described band otch valve block 15.Described two word otch cutting-ins are identical.Described two word otch can be mutually vertical, also can be the angle setting in other.Preferably, described two word otch are mutually vertical.Described two word otch can intersect in the inside of band otch valve block 15, also can be non-intersect.
Described two valve blocks 14,15 can be rotary structures, can be provided with protruding 17,18 in the middle part of it.Described two valve blocks 14,15 also can be non-rotary structure or other suitable structure, and it can not have projection yet.According to this utility model one preferred embodiment, described two valve blocks 14, the direction of the projection 17,18 on 15 is oppositely arranged.Described protruding 17,18 can also be located at described two valve blocks 14, other optional position on 15.Described projection be arranged so that two valve blocks 14,15 can play good sealing function.Because described projection is coaxial with described valve body, therefore also serve certain guide effect.Described two valve blocks 14, the projection on 15 matches, when have run through thing by time, the hole on described valve block 14 serves the effect of sealing; When do not run through thing by time, the linear cuts on described valve block 15 serves sealing function.
In use, the surface of two valve blocks 14,15 of described haemostatic valve contacts, and there is interference crush.When described two valve blocks 14, when being provided with protruding 17,18 in the middle part of in the of 15, the described protruding surface of 17,18 contacts, and there is interference crush.When described two valve blocks 14, when not having projection on 15, then two valve block surfaces contact, and there is interference crush.Due to two valve blocks 14, when the surface of 15 contacts, there is interference crush, under making described haemostatic valve no matter be in malleation or the environment of negative pressure, all there is good sealing property, can loss of blood be prevented, also can prevent outside air from entering in body.
Described two valve blocks 14, are provided with valve block location structure 19 between 15, be fixed the outer ring of two valve blocks 14,15 by proximal end cap 13 and valve body 12.Described valve block location structure 19 can be snap ring, polygonized structure, also can be other suitable structure.Described two valve blocks 14,15 also can adopt other fixed form.Described valve block location structure 19 adjusts the clamping force of two valve block outer rings together with valve body with proximal end cap, prevents it from coming off, and adjusts the relative axial position of two valve blocks simultaneously.
According to this utility model one preferred embodiment, first sheath pipe and convergent divergent channel are combined together, send in body along seal wire, then seal wire is withdrawn from.Due to the sealing property of haemostatic valve 10, blood can not flow out external.The street corner, Rule that can also be connected by haemostatic valve 10 one end is to injecting heparin in body, and due to the sealing property of haemostatic valve 10, air can not enter in body.
Embodiment of the present utility model is not limited to described in above-described embodiment; when not departing from spirit and scope of the present utility model; those of ordinary skill in the art can make various changes and improvements to this utility model in form and details, and these are all considered to fall into protection domain of the present utility model.
