Abstract
The utility model discloses a hemoperfusion device. Filter screens (4) are arranged between end covers (2) and end surfaces of a middle cylinder (1), wherein plain cushions (6) are arranged between the end covers (2) and the filter screens (4); two raised waterproof lines (2b) are arranged on the end surfaces of the end covers (2), which are in contact with the plain cushions (6); a gland (5) is in thread fit with one end part of the middle cylinder (1); the edge of the gland (5) extends outwards to form a protective circle (5b); and ring-shaped stepped surfaces are arranged on the inner wall of the gland (5) to limit the outer edges of the end covers (2), so as to tightly press the end covers (2) on a cylinder opening of the middle cylinder (1). The hemoperfusion device sealed by adopting a thread fit manner has the advantages that the processing technology is relatively simple, special equipment is not needed in the production process, and the sealing performance is good; and as the processing technology is simple, the processing precision is improved, the reject rate is greatly reduced and the production cost is saved.
Description
Technical field
This utility model relates to medical instruments field, relates in particular to the blood perfusion device that a kind of blood purification is used.
Background technology
In recent years, the blood purification therapy develops rapidly and popularizes in China.Wherein hemoperfusion is one of important way of blood purification.At present, blood perfusion technique is widely used in clinical, not only serious symptom poisonous substance, drug intoxication is had good curative effect, and also can be used for the treatment of many chronic and refractories and difficult disease.So the demand of disposable blood perfusion device increases year by year.
Blood perfusion device is connected in the outer circulation bloody path of lead body in the blood purification process, and adsorbent is with the absorption of the toxicant in the blood when tank body for blood flow, and the blood that is cleaned gets into body-internal-circulation again.So the sterilization of perfusion device, the particularly sealing after the sterilization are stored, transportation is extremely important.In the transportation, if the perfusion device is poorly sealed, can cause the material of filling in the air admission perfusion device internal contamination perfusion device, gnotobasis is destroyed, and content can leak out, and causes the perfusion device contaminated equally.
At present, the blood perfusion device of being produced is that ultra-sonic welded is an one.This structure is through the production practices in 2 years, and it is very high to add the man-hour permissible accuracy in the mould manufacturing; Percent defective during injection moulding is than higher, and production process needs specialized apparatus simultaneously, and complex process, processing cost are higher relatively.
The utility model content
This utility model technical problem to be solved is to provide a kind of technology manufacturing simple blood perfusion device.
The technical scheme of this utility model is following: a kind of blood perfusion device; Comprise middle tube (1), end cap (2), small cap (3), filter screen (4) and gland (5), its key is: tube (1) two ends are sealed by an end cap (2) respectively in said, and said end cap (2) central authorities are provided with blood mouth (2a); This blood mouth (2a) is by small cap (3) press seal; Be provided with filter screen (4) between said end cap (2) and middle tube (1) end face, be provided with plain cushion (6) between this end cap (2) and the filter screen (4), said end cap (2) and plain cushion (6) end face that is contacted are provided with the water-proof wire (2b) of two convexities; Said gland (5) cooperates with middle tube (1) end thread; This gland (5) edge extends to form guard ring (5b) outward, and it is spacing to end cap (2) outer edge that said gland (5) inwall is provided with annular step surface, and end cap (2) is pressed on middle tube (1) nozzle.
Selection seals through threaded engagement, the stubborn mode that connects, and abandons ultra-sonic welded, and the technology manufacturing is relatively simple, and production process does not need special equipment, greatly reduces percent defective; Simultaneously end cap (2) is pressed tightlyer with the water-proof wire (2b) that plain cushion (6) end face that is contacted is provided with two convexities, and sealing effectiveness is better like this, guard ring (5b) the intensity of having strengthened gland (5) is set, and can erect placement.
The axial uniform distribution of above-mentioned gland (5) outer circumference surface fluted (5a).Be in order to increase friction, to make things convenient for gland (5) to be tightened on the middle tube (1).
The T shape silica gel point pad (7) of sealing blood mouth (2a) oral area is housed in the small cap (3).Blood mouth (2a) and end face are all sealed, form the two dimension sealing.
Above-mentioned blood mouth (2a) and small cap (3) threaded engagement, the peripheral end cap (2) of said blood mouth (2a) is gone up and is provided with salient point with the corresponding position of small cap (3) end face, and said blood mouth (2a) end face is provided with and the corresponding groove of this salient point.After small cap (3) is tightened with blood mouth (2a), after salient point gets into corresponding groove, has the revolution of preventing, with the effect of its pinning.
Beneficial effect: this utility model adopts threaded engagement to seal, and processing technique is fairly simple, and production process does not need specialized apparatus; Favorable sealing property is because the simplification of processing technique has reduced machining accuracy; Greatly reduce percent defective, practiced thrift production cost.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment this utility model is described further:
Like Fig. 1, Fig. 2, shown in Figure 3, a kind of blood perfusion device is made up of middle tube (1), end cap (2), small cap (3), filter screen (4) and gland (5) etc.Tube (1) two ends are sealed by an end cap (2) respectively in said; Said end cap (2) central authorities are provided with blood mouth (2a); This blood mouth (2a) is by small cap (3) press seal; Be provided with filter screen (4) between said end cap (2) and middle tube (1) end face, be provided with plain cushion (6) between this end cap (2) and the filter screen (4), said end cap (2) and plain cushion (6) end face that is contacted are provided with the water-proof wire (2b) of two convexities; Said gland (5) cooperates the axial uniform distribution of gland (5) outer circumference surface fluted (5a) with middle tube (1) end thread.This gland (5) edge extends to form guard ring (5b) outward, and guard ring (5b) outer end is concordant with small cap (3) outer end, and it is spacing to end cap (2) outer edge that said gland (5) inwall is provided with annular step surface, and end cap (2) is pressed on middle tube (1) nozzle.Blood mouth (2a) and small cap (3) threaded engagement are equipped with the T shape silica gel point pad (7) of sealing blood mouth (2a) oral area in the small cap (3).The peripheral end cap (2) of said blood mouth (2a) is gone up and is provided with salient point with the corresponding position of small cap (3) end face, and salient point forms a circle on the end cap (2) of blood mouth (2a) periphery.Said blood mouth (2a) end face is provided with and the corresponding groove of this salient point.
