Abstract
A medicine liquid filter of a disposable infusion apparatus is composed of an upper housing having an inner chamber, a medicine liquid filtering membrane and a lower housing having the inner chamber; the taper pipes are provided on the upper housing and the lower housing; the upper housing and the lower housing are in sealed fixable connection; and the medicine liquid filtering membrane is fixed in the inner chamber of the upper housing or the lower housing. The utility model is characterized in that an annular positioning sleeve is arranged on the lower housing; and a positioning sheet is provided in the annular positioning sleeve. The utility model prevents the phenomenon of release of an infusion needle and the medicine liquid filter at the fitting position so as to avoid the inconvenience to the patient and the medical personnel; and meanwhile, the medicine liquid filter of the disposable infusion apparatus simple in structure, convenient in operation, low in cost, and easy in implementation is suitable for being widely popularized and used.
Description
Technical field
This utility model belongs to medical equipment, specifically is a kind of filter that is used for filtering liquid medicine on the transfusion device.
Background technology
Liquid medicine filter is mounted in the equipment of disposable transfusion device terminal, mainly is made up of housing and filter membrane, is used for the particulate matter of filtering medicinal liquid 3-5 ч.Transfusion device is in clinical use, the patient often has in various degree little trick (such as last toilet, stir etc. on one's sick bed), will pullling in various degree be arranged to transfusion device like this, the phenomenon that transfusion needle and liquid medicine filter cooperation place are loosening even come off appears sometimes, this not only can cause the waste and the pollution of medicinal liquid, also can cause the misery of changing the transfusion device secondary puncture, also increase workload simultaneously to medical personnel to the patient.
The utility model content
The purpose of this utility model is the deficiency that overcomes above-mentioned existence, and a kind of disposable infusion set liquid medicine filter that can effectively avoid transfusion needle and liquid medicine filter cooperation place to become flexible, come off is provided.
For achieving the above object, the technical scheme that this utility model adopted is: the disposable infusion set liquid medicine filter, lower house by upper shell, liquid medicine filtering membrane and the band inner chamber of being with inner chamber is formed, all have Taper Pipe on upper shell and the lower house, wherein upper shell and lower house are sealedly and fixedly connected, described liquid medicine filtering membrane is fixed in the inner chamber of upper shell or lower house, it is characterized in that lower house is provided with the circular orientation cover, is provided with spacer in the described circular orientation cover.
Circular orientation described in this utility model is set on the lower house Taper Pipe.
Described liquid medicine filtering membrane is separated into two parts with the inner chamber of upper shell and the fixing back of lower house composition.
The diametric(al) that described spacer is fixed on the inwall of circular orientation cover and direction and circular orientation are overlapped is consistent.
Described spacer is two, and symmetry is fixed on the circular orientation cover inwall.
This utility model adds a location ring set in liquid medicine filter lower house 6:100 cone joint periphery, ring set inner diameter direction adds two spacers again, when liquid medicine filter cooperates with the transfusion needle stand, the double-vane of transfusion needle stand port just is stuck on the spacer of liquid medicine filter positioner, cooperate firmly, so just solve the phenomenon that transfusion needle and liquid medicine filter cooperation place get loose, thereby avoided the inconvenience of bringing for patient and medical personnel.Utility model is simple in structure, easy to operate, with low cost simultaneously, realizes easily, is fit to extensively promote the use of.
