CN203059708U - Combined pipe cover - Google Patents

Abstract

The utility model discloses a combined pipe cover which comprises a pipe cover and a rubber plug. The rubber plug is positioned in the pipe cover; a groove part beneficial to puncture is arranged on the rubber plug; a hole is formed in the top of the pipe cover in the position corresponding to the groove part; a sealing membrane used for sealing the hole is also arranged on the pipe cover; and the pipe cover and the rubber plug adopt an integrally formed structure. The combined pipe cover prevents the rubber plug inside the pipe cover from being directly exposed to the air by arranging the sealing membrane used for sealing the hole at the top of the pipe cover on the pipe cover, and eliminates the phenomenon that blood sampling accident occurs because the groove part of the rubber plug is easily polluted, further more, the pipe cover and the rubber plug adopt an integrally formed structure, the process for assembling the pipe cover and the rubber plug is reduced, so that the production cost is reduced.

Further, diaphragm seal also is provided with the protuberance of being convenient to grip.

Further, the pipe lid comprises the pipe tegmental wall, the inside of pipe tegmental wall is provided with boss is positioned at pipe tegmental wall inner and upper with formation upper chamber, plug comprises tight plug hat of filling upper chamber, the plug hat is extended with the plug neck that diameter diminishes downwards, makes that the space between plug neck and the boss closely cooperates with the test tube that is used for sealing.

Further, diaphragm seal covers by welding or bonding the connection with pipe.

The utlity model has following beneficial effect:

This utility model compound tube lid by cover the diaphragm seal that is provided for sealing the hole that is positioned at the pipe tops at pipe, has been avoided being arranged in the inner plug of pipe lid and has been directly exposed to air, and the concave part of eliminating plug is vulnerable to pollute the situation that causes the blood sampling accident to take place; And pipe lid and the structure that plug is formed in one in this utility model compound tube lid have been saved the pipe lid operation required with the plug assembling, thereby have been reduced manufacturing cost.

Except purpose described above, feature and advantage, this utility model also has other purpose, feature and advantage.With reference to figure, this utility model is described in further detail below.

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, but the multitude of different ways that this utility model can be defined by the claims and cover is implemented.

Referring to Fig. 1, preferred embodiment of the present utility model provides a kind of compound tube lid 10, comprise that pipe covers 1 and plug 2, plug 2 is positioned at pipe and covers 1, plug 2 is provided with and is beneficial to the concave part 21 that pierces through, pipe cover 1 top and is provided with hole 12 in the position corresponding with concave part 21, manages and covers the diaphragm seal 3 that also is provided with on 1 for closed hole 12.Diaphragm seal 3 will be managed 12 sealings of the hole covered on 1, be directly exposed to air thereby avoided being arranged in the concave part 21 that pipe cover on 1 the plug 2, and the concave part 21 of having eliminated plug 2 is vulnerable to pollute the situation that causes the generation of blood sampling accident.

Preferably, diaphragm seal 3 covers on 1 by welding or be bonded in pipe, will be positioned at hole 12 sealings that pipe covers 1 top.

With reference to Fig. 2, manually tear diaphragm seal 3 in use for convenience, diaphragm seal 3 also is provided with the protuberance of being convenient to grip 31.
