Abstract
The utility model discloses a medicine liquid filter with screw threads. The medicine liquid filter with the screw threads is composed of an upper shell body with an inner cavity, a medicine liquid filtering membrane and a lower shell body with an inner cavity. The upper shell body and the lower shell body are both provided with taper pipes, and are fixed and connected to a whole in a sealing mode, and the medicine liquid filtering membrane is fixed in the inner cavity of the upper shell body or the lower shell body. The medicine liquid filter with the screw threads is characterized in that connecting threads are arranged on the peripheral wall of the cone joint of the lower shell body. The connecting threads are added to the outer surface of the cone joint which is 6:100 of the lower shell body of the medicine liquid filter, and therefore the aim of connecting the medicine liquid filter and a transfusion needle seat through the threads is achieved, and the medicine liquid filter has the advantages of being high in seal performance and high in solid degree. Therefore, the phenomenon that the matching position of a transfusion needle and the medicine liquid filter loosens is solved, and inconvenience brought to a patient and medical workers is avoided. At the same time, the medicine liquid filter is simple in structure, convenient to operate, low in cost, easy to achieve and suitable for being popularized and used widely.
Description
Technical field
This utility model relates to medical apparatus and instruments, specifically a kind of liquid medicine filter for transfusion device.
Background technology
Liquid medicine filter is mounted in the equipment of disposable transfusion device terminal, mainly is comprised 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 upper 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 waste and the pollution of medicinal liquid, also can cause the misery of changing the transfusion device secondary puncture to the patient, also increase workload to medical personnel simultaneously.
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.
The technical scheme that this utility model adopts to achieve these goals is as follows: a kind of screw thread liquid medicine filter, by forming with the upper shell of inner chamber, liquid medicine filtering membrane with the lower house of inner chamber, on upper shell and the lower house all with Taper Pipe, wherein upper shell and lower house are sealedly and fixedly connected and are integral, described liquid medicine filtering membrane is fixed in the inner chamber of upper shell or lower house, it is characterized in that: described lower house cone joint periphery wall is provided with connecting thread.
According to a kind of screw thread liquid medicine filter described in the utility model, it is characterized in that described liquid medicine filtering membrane is separated into two parts with upper shell and the fixing rear inner chamber that forms of lower house.
This utility model increases connecting thread at liquid medicine filter lower house 6:100 cone joint outer surface, therefore realizes liquid medicine filter and the purpose that the transfusion needle stand is threaded, and has good airproof performance, and firmly degree is high.So just solve the phenomenon that transfusion needle and liquid medicine filter cooperation place get loose, thereby avoided the inconvenience that brings to patient and medical personnel.Utility model is simple in structure, easy to operate, with low cost simultaneously, easily realizes, is fit to extensively promote the use of.
Description of drawings
Fig. 1 is this utility model structural representation
Among the figure: the 1-upper shell; 2 liquid medicine filtering membranes; The 3-lower house; The 4-connecting thread.
The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is described further.
As shown in Figure 1: a kind of screw thread liquid medicine filter, by forming with the upper shell 1 of inner chamber, liquid medicine filtering membrane 2 with the lower house 3 of inner chamber, on upper shell 1 and the lower house 3 all with Taper Pipe.Wherein upper shell 1 and lower house 3 are sealedly and fixedly connected and are integral, and described liquid medicine filtering membrane 2 is fixed in the inner chamber of upper shell 1 or lower house 3, and liquid medicine filtering membrane 2 just is separated into two parts with upper shell 1 and the lower house 3 fixing rear inner chambers that form like this.
This utility model improvements of the present utility model just are to be provided with connecting thread 4 at lower house 3 cone joint periphery walls, and concrete is the 6:100 cone joint periphery that connecting thread 4 is arranged on the liquid medicine filter lower house.The infusion needle seat inner chamber also is designed to screw-like in use, so so that liquid medicine filter be threaded with the transfusion needle stand.When liquid medicine filter and transfusion needle stand when cooperating, by rotation transfusion needle stand liquid medicine filter is cooperated closely with the needle stand of infusing, until rotate motionless till.Needle stand cooperates with liquid medicine filter firmly without leaking like this, has so just solved that transfusion needle and liquid medicine filter cooperation place get loose, the phenomenon of leakage, thereby has avoided the inconvenience that brings to patient and medical personnel.Therefore this screw thread liquid medicine filter principle is simple, easy and simple to handle, safe, easily realize, relatively be fit to promote the use of widely.
