Description
Technical field
This utility model relates to a kind of blood mouth sealing device for blood perfusion device.
Background technology
In recent years, blood purification therapy develops rapidly in China and popularizes.Wherein hemoperfusion is one of important way of blood purification.At present, blood perfusion technique is widely used in clinical, not only has good curative effect to serious symptom poisonous substance, drug intoxication, and also can be used for the treatment of many chronic and refractories and difficult disease.Therefore the demand of disposable blood perfusion device increases year by year.Blood perfusion device, in blood purification process, is connected in the circulation bloody path outside lead body, and when blood flows through tank body, adsorbent is by the toxicant absorption in blood, and the blood be cleaned enters body-internal-circulation again.So sealed type storage after the sterilizing of perfusion device, particularly sterilizing, transport extremely important.In the process of sealing transport, if perfusion device is poorly sealed, air can be caused to enter, pollute the material of filling in perfusion device, and content can leak out, and causes perfusion device contaminated equally.Blood mouth on perfusion device gland and blood mouth small cap are one of key points of perfusion device sealing, present great majority are all adopt threaded engagement, push down blood mouth by sealing gasket and reach sealing, facts have proved that this sealing means single pass screwed tight pushes down blood mouth sealing effectiveness not satisfactory, become a difficult point of perfusion device sealing.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of blood mouth sealing device for blood perfusion device, is applicable to overcoming deficiency of the prior art.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: for the blood mouth sealing device of blood perfusion device, comprise lid and blood mouth mouth, described blood mouth mouth can be stretched in described lid bottom, the outer wall that described lid stretches into described blood mouth notch portion has external screw thread, and described blood mouth mouth inwall has the female thread with described external screw thread adaptation;
Described lid external wall of upper portion has annular groove, described blood mouth mouth outer wall have two groups of clamping unit, described clamping unit lays respectively at the both sides of described blood mouth mouth, described clamping unit comprises the pole of horizontal direction, articulated jib, inserted block and back-moving spring, described pole one end is fixed on the outer wall of described blood mouth mouth, described articulated jib and described pole hinged, the two ends of described back-moving spring are individually fixed in inside described blood mouth mouth outer wall and described articulated jib, described inserted block is fixed on the upper end of described articulated jib, and described inserted block one end can be stretched in described annular groove.
Further, the top of described articulated jib has towards the handle extended away from described blood mouth mouth outer wall direction.
Further, described blood mouth mouth upper surface has the groove that can hold sealing ring in the position that described lid contacts.
The advantage that this utility model has and good effect are: owing to adopting technique scheme, good sealing effect, not easily loosen distortion in transit.

Fig. 1 is overall structure cross-sectional schematic of the present utility model;
In figure: 1-lid; 2-external screw thread; 3-annular groove; 4-blood mouth mouth; 5-pole; 6-articulated jib; 7-inserted block; 8-back-moving spring.
Detailed description of the invention
As shown in Figure 1, this utility model provides a kind of blood mouth sealing device for blood perfusion device, and comprise lid 1 and blood mouth mouth 4, blood mouth mouth 4 can be stretched in lid 1 bottom, the outer wall that lid 1 stretches into blood mouth mouth 4 part has external screw thread 2, and blood mouth mouth 4 inwall has the female thread with external screw thread 2 adaptation;
Lid 1 external wall of upper portion has annular groove 3, blood mouth mouth 4 outer wall have two groups of clamping unit, clamping unit lays respectively at the both sides of blood mouth mouth 4, clamping unit comprises the pole 5 of horizontal direction, articulated jib 6, inserted block 7 and back-moving spring 8, pole 5 one end is fixed on the outer wall of blood mouth mouth 4, and articulated jib 6 is hinged with pole 5, and the two ends of back-moving spring 8 are individually fixed in inside blood mouth mouth 4 outer wall and articulated jib 6, inserted block 7 is fixed on the upper end of articulated jib 6, and inserted block 7 one end can be stretched in annular groove 3.
In said structure after lid 1 and blood mouth mouth 4 screw, inserted block 7 stretches in annular groove 3, and under the effect of back-moving spring 8, inserted block 7 makes lid 1 loosen with coordinating of annular groove 3, ensure that the sealing of lid.
The top of articulated jib 6 has towards the handle (not shown) extended away from blood mouth mouth 4 outer wall direction, is convenient to inserted block 7 from pull-out in annular groove 3.
Blood mouth mouth 4 upper surface has the groove (not shown) that can hold sealing ring in the position that lid 1 contacts.
Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to this utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
