Abstract

The utility model relates to a syringe for internal medical care, which mainly solves the problems that: the traditional syringe with a long needle head is easy to deviate from a puncture site due to the poor hardness and easiness in shaking of a needle bar. The syringe for the internal medical care is characterized in that: the right end of a syringe cylinder (1) is in threaded connection with a connecting tube (2), and the right end of the connecting tube (2) is connected with a needle head (4). The syringe has the characteristics of good hardness and uneasiness in shaking.

Description

Syringe is used in a kind of internal medicine nursing

Technical field

This utility model relates to medical instruments field, and syringe is used in a kind of specifically internal medicine nursing.

Background technology

Usually to use the syringe that is connected with the minute hand head when in medical field, injecting; For example carry out oral cavity internal diseases or curing throat disease, used syringe is by the ordinary syringe front end minute hand head, the structure of this minute hand head and the structural similarity of common syringe needle to be installed at present; Just length extends; But because shank is long, make this minute hand head difference of hardness, be prone to shake, when puncture in the oral cavity, making a movement slightly will make needle point depart to need the site of puncture; Especially run into psychentonia or ill-matched patient, very easily cause danger.

Summary of the invention

In order to overcome the existing syringe that has the minute hand head owing to shank difference of hardness, the easy problem that is prone to depart from the site of puncture of shaking, this utility model provides a kind of internal medicine nursing to use syringe, this syringe to have the characteristics of good hardness, difficult shake.

The technical scheme of this utility model is: syringe is used in a kind of internal medicine nursing, comprises injection tube, syringe needle, and described injection tube right-hand member is connected with connection tube through screw thread, and described connection tube right-hand member connects syringe needle.

Be provided with filter pad between described connection tube and the syringe needle, the outer surface at described connection tube left end screw thread place is provided with several convexities.

The utlity model has following beneficial effect: owing to adopted such scheme; Between injection tube and syringe needle, increased connection tube,, so just increased the hardness of shank because the diameter of connection tube is bigger than syringe needle diameter; Avoid the shank shake; Simultaneously, also can alleviate the feared state of mind that some patient sees long syringe needle, avoid causing danger.

1-injection tube among the figure, 2-connection tube, 3-filter pad, 4-syringe needle.

The specific embodiment

Below in conjunction with accompanying drawing this utility model is described further:

By shown in Figure 1, syringe is used in a kind of internal medicine nursing, comprises injection tube 1, syringe needle 4; Described injection tube 1 right-hand member is connected with connection tube 2 through screw thread, and described connection tube 2 right-hand members connect syringe needle 4, and the outer surface at described connection tube 2 left end screw thread places can be provided with several convexities; Holding non-slip when connection tube 2 is connected with injection tube 1; The material of described connection tube 2 can be identical with injection tube 2, and connection tube 2 adopts interference fit with syringe needle 4, and syringe needle 4 can be directly installed on the connection tube 2.For preventing that injection from containing impurity, be provided with filter pad 3 between described connection tube 2 and the syringe needle 4, filter pad 3 can be provided with in the syringe needle 4 in advance, when connection tube 2 is connected with syringe needle 4, filter pad 3 is clipped between the two.

This syringe is owing to increased connection tube 2 between injection tube 1 and syringe needle 4; And the diameter of connection tube 2 has played over-drastic effect less than injection tube 1 diameter and greater than syringe needle 4 diameters, has increased the hardness of shank; Avoid the shank shake, can prevent that needle point from departing from the site of puncture.

Claims (1)

1. syringe is used in an internal medicine nursing; Comprise injection tube (1), syringe needle (4); It is characterized in that: described injection tube (1) right-hand member is connected with connection tube (2) through screw thread; Described connection tube (2) right-hand member connects syringe needle (4), and the outer surface at described connection tube (2) left end screw thread place is provided with several convexities, is provided with filter pad (3) between described connection tube (2) and the syringe needle (4).
